In a prospective, multi-center cohort study, 106 consecutive participants with preserved ejection fraction were evaluated with coronary angiography, invasive coronary physiologic and vasoreactivity testing, and cardiac magnetic resonance imaging. A total of 51% of the study participants had obstructive epicardial coronary artery disease, 66% had endothelium-independent coronary microvascular dysfunction, and 24% had endothelium-dependent coronary microvascular dysfunction.
The findings of this study suggest that obstructive epicardial coronary artery disease and coronary microvascular dysfunction are common and often unrecognised in hospitalised patients with heart failure with preserved ejection fraction.
