<br /><br />Testing for circulating troponin is a mainstay of a heart attack workup. Troponin is a cardiac protein that is released into the bloodstream by damaged heart muscle. <br /><br />To investigate whether more routine troponin level testing might be of predictive value, University of Edinburgh researchers drew troponin levels on 4240 subjects with a history of angina, chest pains of cardiac origin. Troponin levels were 2-fold higher in those subsequently found to have coronary artery disease on cardiac angiography. Those with troponin levels higher than 10 ng/L had a 50% higher risk of heart attack or death.<br /><br />The researchers suggest that more routine troponin level determinations may alert patients and their medical teams to potential risks and thereby save lives.<br /><br />https://www.jacc.org/doi/10.1016/j.jacc.2023.05.046<br /><br />#troponin #heartattack #cardiovascular #coronaryaterydisease<br />
