Clinical characteristics and outcomes of patients with angina and heart failure in the CHARM (Candesartan in Heart Failure Assessment of Reduction in Mortality and Morbidity) Programme.
To investigate the relationship between angina pectoris and fatal and non-fatal clinical outcomes in heart failure with reduced and preserved ejection fraction (HF-REF and HF-PEF, respectively).Of 7599 patients in the CHARM program, 5408 had ischaemic heart disease; 3855 had HF-REF (ejection fraction ≤45%) and 1553 had HF-PEF. These patients were separated into three groups: no history of angina, previous angina, and current angina. Three coronary outcomes were examined: fatal or non-fatal myocardial infarction (MI); MI or hospitalization for unstable angina (UA); and MI, UA or coronary revascularization. The composite heart failure outcome of cardiovascular death or heart failure hospitalization (HFH) was also analysed, along with its components and all-cause mortality. New York Heart Association functional class was worse in both HF-REF and HF-PEF patients with current angina compared with patients without angina (P < 0.001 and P = 0.005 respectively), despite similar clinical examination findings and ejection fraction. Patients with current angina had a higher risk of all three coronary outcomes (adjusted hazard ratios ranging from 1.8-3.1) than those without angina but did not have a higher risk of heart failure outcomes or all-cause mortality.In patients with heart failure current angina is associated with significantly more functional limitation and a higher risk of coronary events, across the spectrum of left ventricular ejection fraction.
