A research study conducted by Indian researchers has found the prominent reasons for heart attacks. “Prevalence of coronary artery disease (CAD) in India is progressively increasing as shown by data that cardiovascular diseases (CVDs) were accountable for 28.1% of total deaths and 14.1% of total disability-adjusted life years (DALYs) in 2016, compared to 15.2% and 6.9%, respectively, in 1990,” the study report says.
