Calcium channel blockers and outcomes in older patients with heart failure and preserved ejection fraction

Academic Article


  • Background-Little is known about associations of calcium channel blockers (CCBs) with outcomes in patients with heart failure and preserved ejection fraction (EF). Methods and Results-Of the 10 570 hospitalized patients with heart failure and preserved EF, ≥65 years, EF ≥40%, in the Organized Program to Initiate Lifesaving Treatment in Hospitalized Patients with Heart Failure (OPTIMIZE-HF; 2003- 2004), linked to Medicare data (through December 31, 2008), 7514 had no prior history of CCB use. Of these, 815 (11%) patients received new discharge prescriptions for CCBs. Propensity scores for CCB initiation, calculated for each of the 7514 patients, were used to assemble a matched cohort of 1620 (810 pairs) patients (mean age, 80 years; mean EF, 56%; 65% women; 10% black) receiving and not receiving CCBs, balanced on 114 baseline characteristics. The primary composite end point of all-cause mortality or heart failure hospitalization occurred in 82% and 81% of patients receiving and not receiving CCBs (hazard ratio for CCBs, 1.03; 95% confidence interval, 0.92-1.14). Hazard ratios (95% confidence intervals) for allcause mortality, heart failure hospitalization, and all-cause hospitalization were 1.05 (0.94-1.18), 1.05 (0.91-1.21), and 1.03 (0.93-1.14), respectively. Similar associations were observed when we categorized patients into those receiving amlodipine and nonamlodipine CCBs. Among 7514 prematch patients, multivariable-adjusted and propensity-adjusted hazard ratios (95% confidence interval) for primary composite end point were 1.03 (0.95-1.12) and 1.02 (0.94-1.11), respectively. Conclusions-In hospitalized older patients with heart failure, new discharge prescriptions for CCBs had no associations with composite or individual end points of mortality or heart failure hospitalization, regardless of the class of CCBs.
