Meta-analysis addressing the impact of cardiovascular-acting medication on peak oxygen uptake of patients with HFpEF.
Abstract
As our therapeutic armamentarium for HFpEF is insufficient, research has been focusing on the potential beneficial effect of existing pharmaceutical regimens on this specific patient population. A series of RCTs have recently examined the impact of various pharmaceutical treatments with proven benefit in HFrEF, on the improvement of symptoms of HFpEF patients. This systematic review and meta-analysis comprised studies of adult patients with HFpEF and evaluated the impact of different cardiovascular acting medication on cardiorespiratory fitness, reflected by peak VO2 values measured during CPET. The primary outcome was difference between groups in the change of peak VO2 (ΔpeakVO2). Literature search involved PubMed/MEDLINE, Scopus and Web of Science databases. Our search identified 3634 records and 19 studies were included in qualitative analysis; 12 studies with 1341 patients were finally included in primary outcome analysis. ΔpeakVO2 between baseline and study-end did not significantly change after treatment with spironolactone, ivabradine, sildenafil, or oral inorganic nitrate and neither did difference in 6MWT distance after treatment with spironolactone. Spironolactone led to statistically significant reduction in E/E' ratio study-end values (WMD - 1.64, 95%CI - 2.42 to - 0.86, I2 = 87%, p < 0.0001), as well as to a significant increase in MLHFQ values (WMD 0.75, 95%CI 0.02 to 1.48, I2 = 0%, p = 0.65), indicating deterioration in HRQoL among HFpEF patients.
