Effects of empagliflozin on cardiorespiratory fitness and significant interaction of loop diuretics.

ABSTRACT: The effects of empagliflozin on cardiorespiratory fitness in patients with type 2 diabetes mellitus (T2DM) and heart failure with reduced ejection fraction (HFrEF) are unknown. In this pilot study we determined the effects of empagliflozin 10?mg/d for 4?weeks on peak oxygen consumption (VO2 ) in 15 patients with T2DM and HFrEF. As an exploratory analysis, we assessed whether there was an interaction of the effects of empagliflozin on peak VO2 of loop diuretics. Empagliflozin reduced body weight (-1.7?kg; P?=?.031), but did not change peak VO2 (from 14.5?mL kg-1 min-1 [12.6-17.8] to 15.8 [12.5-17.4] mL?kg-1 min-1 ; P?=?.95). However, patients using loop diuretics (N?=?9) demonstrated an improvement, whereas those without loop diuretics (N?=?6) experienced a decrease in peak VO2 (+0.9 [0.1-1.4] vs -0.9 [-2.1 to -0.3] mL?kg-1 min-1 ; P?=?.001), and peak VO2 changes correlated with the baseline daily dose of diuretics (R?=?+0.83; P?
