Current methods of risk scores and symptoms to identify people at risk of a heart attack are being called into question by researchers at Mount Sinai School of Medicine. Their brief report, published in the Journal of the American College of Cardiology, suggests the current screening tools for heart attack fail to identify half of the people who are at risk. Researchers compared the accuracy of a widely-used screening tool and a newer measure that adds variables for a more comprehensive estimate of risk and lowers missed opportunities for intervention. Authors suggest switching from tools meant to detect heart disease symptoms to methods detecting plaque in arteries for earlier treatment.
