Unstable Angina in the Era of Cardiac Troponin Assays with Improved Sensitivity – a Clinical Dilemma

Clinical Significance • The diagnosis of unstable angina is still commonly used, even in the era of more precise cardiac troponin assays. • Elevated cardiac troponin levels are common in patients considered having unstable angina. • Unstable angina patients have a non-neglectable risk of adverse cardiovascular events. • The clinical management of patients with unstable symptoms rather should depend of an estimation of their ischemic risk than on the basis of strictly applied diagnostic criteria.
