Determinants of troponin release in patients with stable coronary artery disease: insights from CT angiography characteristics of atherosclerotic plaque

Abstract

Chronic clinically silent rupture of non-calcified plaque with subsequent microembolisation may be a potential source of troponin elevation. In light of recent imaging studies, in which patients with positively remodeled non-calcified plaque were shown to be at high risk for developing acute coronary syndromes, hsTnT may serve as a biomarker for such 'vulnerable' coronary lesions even in presumably stable CAD.
