Heart failure (HF) with depressed systolic function is increasingly prevalent in the United States with coronary artery disease (CAD) the most common etiology. Definitive determination of an ischemic vs. non-ischemic etiology of HF often requires invasive x-ray coronary angiography. Both coronary magnetic resonance imaging (cMRI) and late gadolinium enhancement (LGE) have shown promise in the non-invasive detection of CAD in HF patients.
We hypothesized that the combination of cMRI and LGE would have superior performance to either test alone.
We studied a consecutive series of patients with depressed left ventricular ejection fraction (≤ 40%) who underwent both cMRI and LGE. cMRI evidence of CAD in a territory that matched the wall motion abnormalities or subendocardial LGE was considered evidence of CAD. For combined assessment, evidence of CAD by either test was considered a positive result.

Positive Predictive Value
Negative Predictive Value
Among patients with depressed LVEF, cMRI is superior to LGE alone or a combined assessment in characterizing ischemic vs. non-ischemic etiologies of HF with depressed systolic function.
