ABSTRACT
Background: Approximately half of the patients with chronic heart failure have preserved left ventricular systolic function. The trials of rennin-angiotensin system inhibitors (RASIs) in this population have yielded mixed results. We performed a meta-analysis of these trials to evaluate the safety and efficacy of RASIs in heart failure with preserved ejection fraction patients.Methods: A total of 8425 patients from six prospective randomized controlled trials were analyzed. The end points extracted were total mortality, cardiovascular mortality, hospitalization for heart failure, worsening of heart failure, worsening of renal failure, hyperkalemia, hypotension, six minute walk test, quality of life score. RASIs evaluated were perindopril, enalapril, ramipril, valsartan, candesartan and irbesartan. Combined odds ratios (OR) across all the studies and 95% confidence intervals (CI) were computed.
