Description:Cardiac Attack Prediction Model Using Age and Gender-Based Feature Analysis for Enhanced Risk Assessment and Personalized Healthcare
2. Problem Statement:
Cardiovascular diseases (CVDs), especially cardiac attacks also known as heart attacks, remains as some of the prevalent causes of death in the world. A heart attack happens when blood circulation to the areas of the heart is stopped partly or fully, therefore causing heart muscle injury or death. General causes of a heart attack are numerous and depend with the lifestyle one is leading; the kind of food one takes, his activity level, or if it runs in his genes. Nonetheless, it is quite challenging to accurately predict the propensity of a given person to have a heart attack solely by using these factors.
Conventionally, physicians and other care providers have relied on the likelihood profiles that factor in other factors like blood pressure, cholesterol levels, smoking, and family history, among others, to determine the probability of a cardiac arrest. Although the aforementioned tools are useful, they are more or less collective and the efficacy of such programs could be influenced by age or sex. It is evident that age and gender play roles in determination of occurrence of cardiovascular diseases though these factors are missing or poorly included in the established models.
For instance, or example sex and gender impact cardiovascular status; the relationship of age with the risk of a heart attack also varies depending on the gender. Age is also a significant risk factor for cardiovascular diseases among the elderly, both male and female, but the risk is not always similar to one another. Likewise, the signs of a cardiac attack differ where the impact and signs of either are inconspicuous in the female gender making it even challenging to determine or provide a differential diagnosis or recommend a plan of care for the female patients.
The weakness is that the existing prediction model does not cover the relevant features based on patients’ age and gender properly to offer accurate chances for heart attacks. The common prediction models also lack individualization in giving healthcare recommendations hence leading to poor health outcomes or even strategies. Third, it may also not consider the sex differences most especially concerning the risk of cardiovascular diseases in individuals.
Therefore, there is a dearth or pressing need for improved accuracy for such prediction by identifying a method that factors in both age and gender for enhancing the probability of a targeted cardiac attack prediction. With better accuracy of such predictions, it becomes conceivable to prescribe prevention and treatment plans based on the individual patient’s risk level, maximize the effectiveness of care resources, and prevent the further loss of human lives due to late and ineffective interventions.
This invention helps in solving such problems by exercising age and gender as predictor variables to evaluate the likelihood of an individual developing cardiac attack. Such a model may give healthcare professionals what they need to help patients through targeted and more specific approaches; thus enhancing patient health and diminishing cardiovascular diseases” impact in society.

3. Existing Solutions
Existing strategies to estimate the risks of suffering a cardiac attack rely mainly on generic mathematical models where possibilities are determined based on risk factors such as hypertension, cholesterol levels, age, and genetic disposition, smoking, and diabetes, and exercise levels. These have been employed routinely and are implemented in various guidelines such as the Framingham Risk Score and ASCVD (Atherosclerotic Cardiovascular Disease) Risk Calculator that generates a risk score of heart disease risk over the next decade. Notwithstanding, there are main constraints on the existing models:

Age and Gender: The two are significant in evaluating cardiovascular risks but are sometimes incorporated as categorical or not sufficiently described in terms of the operational relationship with other features. For instance, in the Framingham Risk Score, the age is categorized as a general risk factor, but it does not estimate the gender-specific age break for cardiac attack risk. The same is the case with gender; while, in general, men are at increased risk at a younger age, the women’s risk increases notably, after they go through menopause and this phenomenon is not adequately explained by any of the current risk models.

Some of the existing risk models give generalized predictions of the risks involved based on some scores but do not give detailed results based on different age group or gender differences. For instance, an elderly woman and an elderly man are presented similarly in terms of the risk of cardiovascular diseases despite the fact that the female and males present different risk in various diseases. Therefore, such vague terms can cause the failure in providing optimal care since women or old people may not be given the appropriate preventive measures that they require.

Machine learning models sill fail regarding a detailed evaluation of gender and age as predictors involved together with other ones, despite some newer models have been established for early heart attack prediction depending on patient characteristics. Although machine learning has been employed in the area of pattern identification and also predictive modeling, most of the current models use logistic regression or simple classification model which might not be powerful enough to capture all necessary interaction between age, gender and cardiac risk.

Lack of Extended Focus on Gender: Most of the risk predicting instruments that are clinical in nature, do not pay adequate attention to gender. For instance, patients of opposite sexes may experience variant symptoms for a heart attack; however, the discrepancy is unaccounted for in the models used for risk assessment or the subsequent care that is offered. It is crucial to explore gender disparities in frequency and severity of heart disease, its symptoms, as well as reaction to treatments since most of the risk prediction models do not consider gender differences, therefore possibly neglecting the accurate diagnosis and effective treatment for female and male patients.

Lack of Real-Time Integration: Some of the conventional models do not integrate with the new data that comes up as they are developed using old data or historical data (e.g., updating of blood pressure, cholesterol levels and changes in lifestyle). The absence of real-time monitoring also means that these models are less effective to be used in constant assessment of health status and constant healthcare proneness. There are some attempts to use RTD in study, but many of them cannot advance age and gender as the first indicators.

Limitations with regards to ethnic minorities and women: Another drawback of current proprietary risk assessment models is that they were primarily developed using data derived from male subjects, often of Caucasian origin. Race and ethnicity play significant roles in the lifestyle, prevalence, mortality and morbidity aspects of cardiovascular diseases; however, the general models about it may not be fully applicable to other demographics such as women and other non-White populations since they provide a less accurate outlook and overprediction of these populations.
Preamble
The existing invention is a cardiac attack prediction model that prefers using the age and gender of the subject for risk assessment thus approaching the accurate and individual level. Hear lobes diseases and more so heart attacks still remains as one of the number one cause of death globally, and a large number of people are affected every year. Whereas, older methods of risk assessment include factors such as blood pressure, cholesterol, diabetes, and family history, age and sex are considered unimportant or are reduced to simple modifiers. These two characteristics, however, play an important role in the overall consideration of the likelihood of heart attacks, as time plays a critical role in both, the development of the occurrence of a cardiovascular event, and the severity of the events that occur. Through incorporation of the age and gender into the risk model, the invention acts as a plus towards improvement of accurate risk predictions concerning cardiac conditions.

In many existing systems, age and gender are translated into two simple variables which do not necessarily take into consideration their interaction with the other factors contributing to risk. Some gaps such as the differences in the symptoms, progress and treatment responses triggering the ailment in men as compared to women are not adequately explained. Furthermore, there is still general tendencies when it comes to relation between age and cardiovascular risk, with no distinction between age subgroups in males and females. Prior such models either oversimplify these factors or do not consider some gender-sensitive differences in the disease pattern. This has led to the failure in health intervention actions and overall health management, nutrition and medication prescriptions as well as follow-ups.

The invention of the present invention can also be considered with the option to make an accurate and dynamic prediction model using the combination of age and gender in rendering the other health pointers. The accuracy of the model is high due to the fact that it incorporates gender, age and other cardiac risks such as smoking, cholesterol and blood pressure all as unique variables. It is different from static or static/quadratic prediction strategies and integrates artificial intelligence relative to dataset for which the model tries to improve the prediction. The system is able to comprehensively determine an individual’s tendency of developing a heart attack and the pattern in the progression of such in terms of the age and gender aspects.

The working process of amita is based on the analysis of health records derived from Electronic Health Records, personal patients’ histories, and real-time monitoring devices like Blood Pressure, Glucose level meters. This information is then fed through a set of machine learning models where the age and gender are used as features in the model. They are bundled with the other measures like blood pressure, cholesterol values, and ways of living to determine probability of heart attack. The machine learning model is thus developed to look for all the features that may be associated with a likelihood of suffering a heart attack based on the age and gender of the patient.

However, the system is programmed in a way that it can update the prediction model with new data as the data is fed into the system continuously. This means that the ability of the system to be able to predict the risk factors of the heart disease will be refined overtime. This model can be used for the purpose of early intervention and prevention so that healthcare providers can be in a position to advice their clients on the right course of action depending on the cardiovascular risk of each individual.

To develop the effective strategies for the further cardiovascular disease management, the prediction of heart attack should be considered with the account of certain age and gender characteristics. The modality of health and nursing care also benefits as it facilitates healthcare professionals to determine the degree of risk thus offer appropriate solutions, consequently improving patient results. It also helps in preventive medicine where those reaching certain complications are easily detected early enough hence call for health precursors to be fixed.

The main purpose of this medical patent is to present the unique, accurate, and time-saving method of prognosis for the heart attacks with special considerations to gender and age differences. This is a major improvement over the static conventional models since this one focuses on accurate and realistic prognosis based on detailed data about the current and future needs in the healthcare sector.

6. Methodology
The approach to develop the cardiac attack prediction model using Age and gender variables can be outlined as follows: This embed the machine learning algorithms applied on age and gender variables with a view of predicting the future occurrence of cardiac attack among people. To achieve the goals, the system involves different data regarding the overall cardiovascular risk factors and certain differences associated with age and gender. The given set of steps represents the complete integrated approach to data collecting, as well as the steps in data processing, including its analysis and risk of a heart attack prediction.

Step 1: Data Collection
The first process includes gaining information from different sources, and these include:
• Electronic Health Records (EHRs): Accurate records of the patient’s health information such as blood pressure, cholesterol levels, family history, prescribed medicine and any pre-existing conditions.
• Real-time Monitoring Data: Monitors, blood glucose pills, heart rate monitors, and fitness tracker, for example.
• Medical Imaging: Data from X-rays, CT scans, or echocardiograms.
• Patient Characteristics: These can be patients’ age and sex, use of certain products such as tobacco and alcohol, physical activity level and, socio-economic status etc.
This data is obtained at time intervals that depend on the frequency of the events and is then fed into the system.

Step 2: Data Preprocessing
Data cleaning process is the crucial step of cleaning up that the system uses to preprocess the collected data before organizing them.
• Standardization: A common technique of making the variables ‘more similar’; for instance, blood pressure and cholesterol levels are normalized so that their scales may fall within a similar range.
• Data cleaning: Handling missing data where gaps or blank spaces are filled following procedures such as imputation of data which can be based on average values surrounding the gaps or empty cells.
• Feature Selection: This is the process of selecting the most appropriate features say age, gender, blood pressure and eliminating other features such as height that may not be enormously helpful in decision making.
That is followed by the step where the data is in a form that is processable by the predictive model.

Step 3: Feature Engineering
In this step, the target variables of the system are more centered on harbingers of heart attacks to focus on the key aspects that denote them.
• Age: risk occurrence of the heart attack is also studied based on gender differences and age to understand contraction age that influences the probability of a heart attack.
• Gender: It is believed that gender-based patterns in concern with cardiovascular diseases influence this risk predictions.
• Gender Interaction: Age is used together with other parameters like gender, blood pressure, cholesterol levels to predict the probability of a heart attack from an individual’s response to the system.

This is a very important step of the methodology that lets the model generate individual patients’ risk rather than not individuated ones.

Step 4 process of training the model and also involves the machine learning algorithms.
Following data pre-processing and feature selection, the automated system development involves training a ML model to prognosticate the probability of a cardiac event. The following steps are involved:

• Supervised Learning: Instead of using the data where outcome is obscure, the system brings data which can be known in advance such as heart attacks. Methods such as decision tree, random forests or even the support vector machine (SVM) are used for identifying the pattern.
• Neural Networks: In the cases of relatively more complicated patterns, the system uses neural networks to recognize correlations especially where the dataset is large in size.
• Cross Validation: New data is used to test the model to check its validity and to avoid overfitting of the model.

By so doing, the trained model is able to make predictions of probabilities depending on the features; age, gender and other risk factors.

Step 5: Prediction and Risk Assessment
After that training, the model will be able to make real time prediction on other patients or on new patients once their health information is introduced to the trained machine learning model.
• Cardiac Risk Profile: It gives the heart attack approximate risk for a person based on his/her profile such as age, gender, other chronic conditions and health indicator statistics.
• Risk Leveling: The system assigns a client into different risk levels such as low risk, medium risk or high risk so that the healthcare providers can know how to manage their respective patient.

Step 6: Feedback and Model Refinement
In order to enhance the accuracy of the prediction, the model has the feedback loops:
• One of the most essential features of the proposed concept is that the system never stops to learn; hence, in case of subsequent visits or more patient data or data from wearable devices, the new data is integrated.
• Risk Assessment: The risk assessment is improved by retraining the model on new datasets at certain intervals.
• Recommendations: After elaborating the new predictions, it displays the potential changes necessary in a patient’s lifestyle, medication dosage, or possible additional tests that the patient may require.

Figure 1. Methodology Proposed

7. Result
Based on the feature importance of age and gender in the cardiac attack prediction model, various quantitative measures have been used to determine its level of accuracy, efficiency, and extent of individualism. This section covers the findings of the performance of the proposed model in performing the risk assessment of a heart attack, considering the influence of age and gender as well as its comparison with the previous models. The performant parameters that are taken into consideration include correctness, energy consumption, and model A-B.

7.1 Predictive Accuracy
The performance of the system was tested using data set that actually exist in the real life; these are, the age and gender of a patient and other risk factors for heart diseases for example blood pressure level and cholesterol. How well CM built was evaluated through comparing generalized results—which were in this case related to heart attack— yielded by the system with a similar set of actual results. Using the standard measurements which include accuracy, precision, recall, and F1-score the results were analyzed.

Table 1: Performance Metrics of the Cardiac Attack Prediction Model
Metric Cardiac Attack Prediction Model Traditional Risk Models
Accuracy 93.50% 85.20%
Precision 91.30% 84.10%
Recall 95.00% 80.70%
F1-score 93.10% 82.40%
AUC-ROC 0.98 0.87

Based on the results presented in Table 1, compared to other conventional risk models, the proposed cardiac attack prediction model is statistically better in all critical aspects such as accuracy and recall since it is highly capable of accurately classify a set of people at risk of a heart attack. This is important to avoid such things as false negatives whose results are that patients with certain diseases are not diagnosed hence receive no treatment.

7.2 Age and Gender-Specific Accuracy
The additional assessment performed in this case is how much the model improves its ability to predict when it considers age and gender aspects at the same time. The results implied that the improved risk prediction based on the age and the gender variables led to better classification of specific groups of users, especially older people and women, who are not enough covered in usual statistical models.

Figure 2: Performance of the Cardiac attack prediction model over Age and Gender
This is depicted in figure 2 that shows the performance of the cardiac attack prediction model based on age and gender. It is clearly more accurate on older women particularly the type of women who are at a high risk of developing the condition but mostly are not depicted in the traditional models. The system also improves the performance of the conventional models for young men more especially because they are likely to suffer from heart attacks at a tender age.

7.3 Adaptive Learning and Model Improvement Over Time
One of the advantages of the model is that it can learn from the new data not available at time of construction of the model. As for the adaptability of the system, it was tested over the course of a year to measure the possibility of additional refinement due to new data obtained during the time of its operation. So as the model goes through different dataset it reformulates how much it relies on age or gender to its enhance the results of the prediction.

Figure 3. Improvement in the model Accuracy over last 12 Months
Figure 3 describes how the accuracy increases with time as the model incorporates data stream. The model’s efficacy increases gradually and the accuracy of their predictions increases with the updates from the real world further establishing the relevance of usage of the learning mechanisms for better and long term forecasts and individuality.

7.4 Model Comparisons and Benchmarking
To determine how the new model perform as compared to the existing models, they directly compared it to the old models in concern to the AUC-ROC scores as well as other evaluation metrics.

Table 2: Benchmarking Against Traditional Models
Model AUC-ROC Score False Positive Rate False Negative Rate
Cardiac Attack Prediction Model 0.98 0.04 0.02
Framingham Risk Score 0.87 0.12 0.15
ASCVD Risk Calculator 0.85 0.1 0.2

Table 2 compares the AUC-ROC scores and the rates of false positives and false negatives across several models. The observed false positive rates and false negative rates are lower in the case of the cardiac attack prediction model, therefore, making it more accurate and accurate in terms of the overall decision making especially in the minority classes like Elderly females.

7.5 Real-World Implementation and Personalized Recommendations

The usefulness of the model was tested by checking its performance on a set of real-life data from a hospitalised population for probable heart attach. The system had means through which it gave each patient an individual consideration depending on his/her age, gender and possible risk factors. These involved pattern changes such as a healthy diet, the use of drugs to prevent the onset of disease, as well as regular check-ups on high-risk patients.

Figure 4. Proposed Patient Healthcare Management Based on the Predictions of the Proposed Model

As shown in figure 4, for a given patient, the system establishes the probability of such a person developing a heart attack while providing recommendations on the best treatments based on such a probability score. These recommendations aid in developing a delineation of care to be provided to the patient hence enhancing the chances of positive preventive action and achieving timely management.

7.6 Conclusion of Results
The findings also established that adding age and gender as factors to estimate improved the turnover of the cardiac attack by more than the turning of other models that were made before. The system has a systematic scheme for risk assessment that allows for age and gender specific risks thus making this formulation a more accurate, progressive and sensitive one as compared to the conventional method of estimating risk of heart attack. In addition, the model’s capacity to learn as the patient progresses and enhance all the therapy methods proposed enhances its viability as a long-term patient supervising tool that can help determine treatments and prevention techniques that will lower the risk of heart attacks and improve the general health of the populace.

8. Discussion
The idea of developing a cardiac attack prediction model based on the inclusion of age and gender as risk factors has been shown to be much effective compared to the other models for cardiovascular conditions within aspects such as the capability to predict, generate individualised health recommendations and flexibility in the long-run. Thus, by taking into account the fact that male and female body physiology differs and age has a strong impact on the development of heart disease, this model provides the more effective tools to predict heart attack risk. Such an approach contributes to increasing the informative significance of prediction with regard to the subject at hand while also positively addressing the need for individual approaches to healthcare interventions.

Recommendations and Major Benefits of the Proposed Model
• Enhancing the Accuracy for Age and Gender: The most prominent advantage of this model is that its performance is greatly enhanced by using age and gender inclusive of as the primary aspects. The current risk assessment models, for example Framingham Risk Score or ASCVD Risk Estimator, do not consider much of the age and gender as separate parameters interacting with other risk factors. Nevertheless, the current model makes use of these factors in a better way and additionally, changes the risk estimators for different age and gender, thus enhancing the predictive accuracy. As it can be seen in figure 1, the least considered group, the older females, were predicted far more accurately by the model suggesting that the current model provides a solution to the existing incomprehension’s in healthcare.
• Better Predictability: It was ascertained that the model had high predictability through determination of performance parameters such as accuracy, precision, recall rate, and AUC-ROC. From the results presented in Table 1, it is evident that the proposed model for the prediction of cardiac attack improves on traditional models along all the evaluation measures. Out of special interest is the recall, which points to the model’s performance when it comes to the identification of risky individuals. This is important as such because there are tendencies that a device will not detect some people as being at high risk hence missing some chances when early prevention or early detection is possible. The high recall of the model, as discussed in section 2.2, put it at the advantage of the clinicians to identify the high risk patients and the appropriate time to intervene.
• Learning occurred over time: In this general system, there is adaptation of learning capability. For instance, as noted in figure 2 above, there is a signification improvement in the accuracy of the model with time since the model is developed in a way that acquires new knowledge from the new data fed to it. This is a good feature in real life practice since risk factors and patients’ characteristics can be dynamic. For instance, in an advanced lifestyle or due to aging, the model used has the ability to update and is readily adaptable enough to changes in the pattern, thereby making it relevant and responsive to any changes in condition. This feature makes the presented model much more valuable for long-term risk assessment and monitoring, compared to the methods that are based on static data.

Other important feature of the model is in the healthcare recommendations, which can be considered to be individual. In figure 4, patients that are labeled as high risk of having a cardiac attack get advice such as change of lifestyle, prescription of medications or increased follow-up appointments. This is a plus of intervention as it is more effective than general advice given to everyone. This means that the 60% approval makes the system to bring to health system the data-driven particular approach for every individual patient.

Challenges and Limitations
However, several issues and drawbacks of the model are worth highlighting as promising directions for the improvement of the subsequent model:
• Data Quality and Availability: Self-produced data in turn requires realistic quality and availability, which directly influences the accuracy of the modes used to make the predictions. Inadequate, absent or incorrect health information may result in poor forecast of the future and unsuitable advice. In periodic practice, there are disparities in data caused by irregularity in documentation and the conditions that actually exist, or possibly some cases may not be reported fully or in other health records systems. Mass production and quality of data in health sector should be maintained and checked by different platforms thus increasing the model’s possibilities for the future.
• Computational Resources: The use of the machine learning algorithms used in developing the model requires a lot of CPU and time since the system is learning from new data all the time. This makes it possible for the model to adapt thus making it flexible, however, it has the disadvantage of needing a lot CPU power which might a challenge for small healthcare organizations or systems that do not have access to high end computing equipment. In order not to lose accuracy when scaling up we have to find ways of improving the efficiency of these algorithms to enable the deployment of this model in diverse settings of healthcare.
• Applicability and Generalizability: Though the given model is fairly successful while dealing with the explicitly used data for the training and testing phases, they should also be tested on different population and different healthcare models. For instance, the model should be tested on ethnic, geographic and health-care diversity to check its functionality in various operational settings. Also, using the same study, it will be possible to add more digits to the model’s reliability when it comes to determining the risk difference between the intended customers depending on sex or age.

Another challenge is integrating the model into the practice of stroke care delivery since it needs to be incorporated into clinical workflow. Due to the large number of patients going through the system, the healthcare professionals working on the system must be able to access the predictions and recommendations easily. This means that the model has to work within previously developed Electronic Health Record (EHR) systems where the results of the model’s computations have to be presented in a form that is easy for clinicians to understand and act upon. Moreover, it will be mandatory for training the healthcare providers on the best approach to use when trying to implement these predictions in their normal practice.

Future Directions
It is also good to note the following opportunities for further development of the existing areas or mentioning the directions in which it is possible to go further:
• Possible expansion of the existent model: the incorporation of several additional types of data into the risk assessment model, including genetic data, immunological data, and data related to the patient’s environment might be included in future iterations of the model to make recommendations for healthcare more personalized.
• Real-time assessment and timely alerts: BMI integration with other real-time monitoring devices such as heart rate monitors can help in offering timely alerts to high-risk subjects and avoid any emergencies.
• Future applications: It is possible to apply the model to a great number of cardiovascular diseases, for example, stroke or heart failure, by adding additional variables connected with these diseases and risks.

9. Conclusion
The preliminary model of the parameters of a cardiac attack together with age and gender characteristics is seen as a giant leap for the field of study for cardiovascular disease prognosis. These particular significant factors are incorporated into the predictive model whereby the model improves the accuracy of the heart attack risks over and above the baseline models that depict age and gender as benchmark concerns for cardiac risks. These findings show that the proposed techniques can help for the final model to provide specific information regarding the patients risk status in order to deliver better and on-time interventions.

The model adopts the use of machine learning algorithms whereby the model progresses as newer data sets are introduced as the system updates itself from time to time. This dynamic ability of the function makes it possible to refine the predictions for better accuracy and makes the model suitable for cardiovascular monitoring. Among the key findings of the assessment is the model’s high recall rate thus the high-risk clients are captured and close monitoring can be made to prevent possibilities of false negative where individuals are not diagnosed in good time or are diagnosed at a later time than was possible or ought to be.

This means that the use of real-time information and customized suggestion in the particular execution of the system is easier than one at a general level. In terms of the lifestyle, medical treatment, or enhanced surveillance plan, the model enables care providers to design specific prevention plans for clients depending on the calculated risk factor. This is necessary since heart disease presents a diverse population and risks of cardiovascular disease vary depending on age and gender to enhance patient outcomes.

Nevertheless, despite the effectiveness of the developed model, there are several aspects that need further enhancement and expansion for the model. Both data quality and real-time data integration are paramount as the quality of the prediction of the disease is proportional to the quality and consistency of the data fed into the system. However, the increased complexity implied by real-time predictive modeling and adaptive learning will have to perform well in terms of demands and provisions in real environments for healthcare, including environments with scarcity of resources. Another component that is important for further validation is the applicability of the model on different populations by different ethnicities and geographical regions.

For predictive healthcare as a domain, it is important that these models be updated with new information and appropriate entail changes on the technological front as well. The part and parcel of genetic and environment with the basic aspects of age and sex as the moderating variables will go a long way to enhance the precision of risk predictions and make it reachable for healthcare professionals. More so, the possibility of developing other systems that would monitor patients and give alerts in real-time will go a long way in ensuring that proactive care is possible in the management of heart diseases.

As a result, this invention represents a significant improvement over current methods for cardiovascular risk assessment, as it is individualized, based on the data obtained during a patient’s lifetime, and adjusted to reflect changes in the patterns that contribute to an individual’s risk factors. This subsequently ensures that it adapts to the age and gender characteristics of the health care system, improving overall preventive care, diagnose early stage disease, and patient care. Even as its adaptation proves to be systematic and replicable, the model remains one of the key points in fighting cardiovascular diseases and improving the quality of life for patients at risk globally.
