Prognostic impact of late gadolinium enhancement in patients with high-sensitivity troponin elevation and non-obstructive coronary arteries

Background Troponin assays have an established role in the diagnosis and risk stratification of patients with acute coronary syndromes. The lack of an accurate diagnosis and the uncertain prognosis when obstructive coronary disease is absent represents a clinical challenge. We sought to describe the distribution of late gadolinium enhancement (LGE) and its impact on hospital readmission and death in patients with raised high-sensitivity troponin T (hsTnT) not attributed to an acute coronary syndrome.
