Researchers at the Indian Institute of Technology (IIT) Madras have developed an AI-based diagnostic tool that can detect early signs of heart attacks using wearable devices. The algorithm analyzes real-time ECG data to identify abnormal patterns that precede a cardiac event. In clinical trials conducted with Apollo Hospitals, the tool demonstrated 92% accuracy in predicting early onset of myocardial infarction. The system sends alerts to both patients and healthcare providers, allowing for immediate intervention. The technology is expected to be integrated into smartwatches and mobile apps, especially for high-risk individuals. It also supports remote monitoring, which can be life-saving in rural or underserved areas. The research has received funding from the Department of Biotechnology and is pending regulatory clearance. If approved, the AI tool could revolutionize preventive cardiology in India, where heart disease is a leading cause of mortality. The innovation reflects India’s growing capabilities in healthtech and medical AI.
