N2 - BACKGROUND: In patients with newly diagnosed heart failure (HF) and left ventricular ejection fraction (LVEF) <50%, little is known whether LVEF per se or presence of coronary artery disease (CAD) provides independent prognostic information on all-cause mortality. METHODS AND RESULTS: Using the WDHR (Western Denmark Heart Registry), we identified 3620 patients with newly diagnosed HF and LVEF 10% to 49% referred for first-time coronary angiography as part of general workup of HF. Patients were stratified by LVEF (10%-35% versus 36%-49%) and presence of CAD. We estimated 10-year all-cause mortality risk and calculated hazard ratios adjusted for relevant comorbidities and risk factors (aHRs). CAD was present in 1592 (44%) patients. Lower LVEF was associated with a relative 15% increased 10-year mortality: 37% for LVEF 36% to 49% versus 42% for LVEF 10% to 35% (aHR, 1.15 [95% CI, 0.99-1.34]). This result did not change when stratified into those with CAD (52% versus 56%; aHR, 1.11 [95% CI, 0.91-1.35]) and those without CAD (27% versus 33%; aHR, 1.24 [95% CI, 0.97-1.57]). In comparison, presence and extent of CAD were associated with a relative 43% increased 10-year mortality (CAD versus no CAD, 55.0% versus 31.5%; aHR, 1.43 [95% CI, 1.25-1.64]). Compared with a matched general population, excess mortality risk was higher for patients with HF and CAD (54.7% versus 26.3%; aHR, 2.10 [95% CI, 1.85-2.39]) versus those with HF and no CAD (31.4% versus 17.2%; aHR, 1.76 [95% CI, 1.52-2.02]). CONCLUSIONS: Among newly diagnosed patients with HF and LVEF <50%, presence and extent of CAD are associated with substantial higher all-cause mortality risk than lower LVEF.
