Dr Manoj Kumar 02 05 Cardiovascular diseases are the most frequently used cause of death in the world with a big impact on health care systems and millions of human lives Early diagnosis and accurate detection are important for effective intervention and treatment planning Predictive modeling techniques in general have long been quite promising as applied to improving the accuracy and efficiency of heart disease detection especially with new approaches in deep learning Convolutional neural networks CNNs recurrent neural networks RNNs hybrid approaches and other technologies and concepts are all part of deep learning approaches which are widely used to analyze complex cardiovascular data like electrocardiograms ECGs medical imaging or clinical records In order to enhance performance accelerate convergence and improve the models interpretability optimization techniques like particle swarm optimization and genetic algorithms are also employed This survey offers a complete review of the latest advances in deep learning methodologies for cardiovascular health prediction with a focus on key methodologies commonly used datasets performance metrics and realworld applications In addition we discuss challenges associated with predictive modeling using deep learning which include data imbalance model interpretability and privacy The paper aims at providing a valuable resource for the researcher and the practitioner giving insights into current trends and potential solutions up to future directions in using deep learning for cardiovascular disease prediction and prevention Copyright (c) Journal of Science Engineering Technology and Management Science.
