Abstract
Background: Medications known to improve outcomes in heart failure (HF) are either not prescribed or prescribed at sub-therapeutic doses. The addition of clinical pharmacists to the HF team positively impacts optimizing prognostic medications for a patient with HF with reduced ejection fraction (HFrEF).
Objective: To assess the intervention of the clinical pharmacist as part of the multidisciplinary (MD) team in up-titration to achieve target doses of key therapeutic agents for HFrEF.
Methods: This was a prospective one group pretest-posttest interventional study; a comparison of the target dose achievement of key therapeutic agents for HFrEF was performed before and after clinical pharmacist interventions.
Results: Out of 110 HFrEF patients, 57.3% were males, and the mean age of patients was 55.8 years (SD 12.6). Cardiomyopathy was the leading cause of HF. At baseline, 86% were on angiotensin-converting enzyme inhibitors/angiotensin receptor blockers/angiotensin receptor-neprilysin inhibitors (ACEIs/ARBs/ARNi) and 93.6% on beta blockers (BBs). At the end of study, the proportion of patients achieved the target dose was significantly increased (0 vs 77.4%, 6.8 vs 85.4%, and 0 vs 55.6%) for ACEIs, ARBs and ARNi, respectively, and (8.6% vs 66.1%; P = 0.001) for BBs. Moreover, the up-titration process was associated with significant improvement in most clinical as ejection fraction and New York Heart Association (NYHA) scale and laboratory characteristics.
Conclusion: As a part of the MD team in the outpatient HF clinic, the clinical pharmacists increased the percentage of HFrEF patients achieving the target or maximal doses of key therapeutic agents and improving clinical and laboratory parameters.
