Abstract:
Heart and circulatory system disorders (CVDs) remain the primary cause of mortalityglobally, necessitating innovative approaches for early diagnosis and treatment. This
research explores the use of machine learning methods for predicting cardiac diseases, by utilizing a comprehensive dataset gathered from four reliable sources. The dataset, integrated based on 11 common features, underwent rigorous preprocessing to ensurehigh data quality for model training. Several machine learning algorithms, suchas
Logistic Regression, Random Forest, and Gradient Boosting and a hybrid model
Voting Classifier were employed to develop predictive models. The performance of
these models was assessed using standard metrics like accuracy, precision, recall, F1score, and confusion matrices. The research revealed that the Logistic Regressionmodel attained an accuracy of 80.52%, the Random Forest model reached 98.05%, theGradient Boosting model achieved 95.13%, and the Voting Classifier achieved99.03%. Ensemble methods, particularly the Voting Classifier, demonstrated superior
predictive accuracy, highlighting the value of combining multiple models. Ethical
considerations, such as data privacy, bias mitigation, and transparency, wereaddressed to ensure the responsible application of machine learning in healthcare. Thefindings suggest that machine learning techniques significantly improve the earlyprediction of cardiac diseases, facilitating timely medical interventions andpersonalized treatment plans, which can improve patient outcomes, lower mortalityrates, and boost healthcare efficiency. The study underscores the importance of
continuous improvement, interdisciplinary collaboration, and ethical responsibilityinthe deployment of machine learning technologies. Future research should explore theintegration of additional features, real-time data, and the application of machinelearning to other chronic diseases to further advance the field. These findings
contribute to the broader goal of leveraging advanced algorithms to revolutionizecardiac disease diagnostics and treatment, promoting a more effective and sustainablehealthcare system.
