Why the study?
Coronary angiography is commonly performed to assess obstructive CAD in HFrEF, but the frequency of obstructive CAD, its independent predictors, and associated outcomes needed to be determined.
What is the prevalence, predictors, and survival impact of obstructive coronary artery disease in patients with HFrEF undergoing coronary angiography?
Cohort (n=260)
What is the prevalence, predictors, and survival impact of obstructive coronary artery disease in patients with HFrEF undergoing coronary angiography?
Obstructive CAD is present in nearly half of HFrEF patients undergoing coronary angiography, and its presence without revascularization is associated with significantly lower survival.

Ghazni et al. (2019) conducted a cohort in Heart failure with reduced left ventricular ejection fraction (HFrEF) (n=260). Coronary angiography was evaluated on Frequency of obstructive CAD (OCAD).
