Long-term surrogate cardiovascular outcomes of SGLT2 inhibitor empagliflozin in chronic heart failure: a systematic review and meta-analysis
Abstract
The sodium‒glucose cotransporter-2 (SGLT2) inhibitor empagliflozin (EMPA) has been demonstrated to reduce the risk of cardiovascular mortality or hospitalization for heart failure (HF) in patients. Nevertheless, data concerning the long-term cardiovascular effects in clinically important subgroups are scarce. A prespecified meta-analysis of randomized controlled trials (RCTs) was conducted to assess the long-term effects of EMPA on cardiovascular outcomes in HF patients, regardless of HF type and glycemic status. The assessment included parameters related to left ventricular (LV) remodeling, including the LV volume, the LV mass index (LVMI), the ejection fraction, the systolic blood pressure, and biomarkers. Moreover, the effects of the treatment on exercise capacity and quality of life (QoL) were analyzed. Furthermore, these cardiovascular parameters were evaluated in prespecified subgroups of HF patients, including type of HF, type 2 diabetes status, and duration of therapy. The quantitative meta-analysis was synthesized and analyzed via the statistical software Stata 17.0. The meta-analysis revealed that EMPA administration significantly contributed to a reduction in systolic blood pressure (SBP) (MD = 4.93 mmHg, 95% CI=[-9.67, -0.19]; P < 0.0001) and left ventricular end-diastolic volume (LVEDV) (MD=-18.03 mL, 95% CI=[-25.4, -10.67], P < 0.0001). Furthermore, left ventricular end-systolic volume (LVESV) (MD=-16.09 mL, 95% CI=[-26.94, -5.25]; P < 0.0001) and N-terminal…
