Heart disease risk calculators may be failing to identify many Indians at risk: Study

Widely used heart disease risk calculators may be failing to identify a large proportion of Indians at risk, according to new research. The study, conducted by a team of scientists from various institutes in India, analysed 4,975 patients with first-time heart attacks. It found that nearly 80% of those who eventually had a heart attack weren't classified as 'high-risk' beforehand.
