Machine and deep learning methods have gained significant prominence in the healthcare industry, particularly for the prediction of cardiac diseases. The increasing prevalence of heart-related diseases underscores the necessity for proactive and accurate healthcare interventions. Machine learning, a data-driven approach, can play a crucial role in recognizing and addressing cardiovascular risks. To achieve this, researchers have utilized a range of classification techniques, such as Support Vector Machines, Random Forests, and Naive Bayes, to unravel the intricate aspects of heart disease prediction. Additionally, ensemble learning techniques, especially Stacking Technique, is employed to further enhance predictive accuracy. However, the ensemble approach has certain limitations. Therefore, confusion matrices are utilized for thorough evaluation and validation, offering better classifier performance. As research advances, prediction models aim to achieve higher accuracy and generalizability. Insights from confusion matrices can help researchers to make more robust and dependable predictions.Future research will investigate the deep learning models to detect subtle patterns in electrocardiogram data, with the aim of enabling earlier identification of cardiovascular conditions. Additionally, the integration of wearable sensor technologies holds promise for continuous risk monitoring and the development of personalized healthcare interventions. These technological advancements possess the potential to fundamentally transform the field of cardiac care, facilitating earlier disease diagnosis and substantially enhancing patient prognosis. In conclusion,the convergence of machine learning and deep learning models heralds a novel era for precision medicine, where data-driven insights empower stakeholders to tackle formidable challenges with unparalleled effectiveness.
