Prognostic impact of angiography-derived index of microcirculatory resistance in patients with dilated cardiomyopathy.

ABSTRACT: Coronary microvascular dysfunction (CMD) has recently been associated with adverse cardiovascular events in patients with heart failure. We investigated the relationship between late gadolinium enhancement (LGE) and CMD, as well as the prognostic value of CMD in predicting long-term prognosis in patients with dilated cardiomyopathy (DCM). Patients with DCM who underwent both cardiac magnetic resonance imaging and coronary angiography were consecutively enrolled. CMD was evaluated using the angiography-derived index of microcirculatory resistance (angio-IMR). The primary endpoint was composite endpoints of all-cause mortality or heart failure hospitalization within 3 years. Among 108 patients (median age, 64 years; women, 27 %), 18 % (19 patients) experienced composite endpoints. The median
