Effects of Empagliflozin in Heart Failure Patients with Type 2 Diabetes: A Biomarker Perspective
Abstract
Sodium-glucose co-transporter inhibitors significantly reduce cardiovascular mortality, hospitalization for heart failure, and improve renal outcomes regardless of diabetes status. This study investigated the effect of empagliflozin on plasma biomarkers to explore underlying mechanisms.Adult patients with type 2 diabetes and heart failure with either left ventricular ejection fraction≤45% (EFFORT-1) or>45% (EFFORT-2) were recruited. Patients received 25 mg empagliflozin or placebo for 48 weeks. Plasma levels of endothelin-1, galectin-3, insulin-like growth factor binding protein-7, and kidney injury molecule-1 (KIM-1) were measured at baseline and at weeks 2, 12, 24, and 48. A total of 63 patients were recruited, 24 in EFFORT-1 and 39 in EFFORT-2. Empagliflozin significantly reduced KIM-1 levels by 38% at week 48 in EFFORT-2 compared with placebo (95% confidence interval: -57%, -13%). No significant impact on other biomarkers was observed.Empagliflozin demonstrated, as shown by the decrease in KIM-1 levels, a renal tubular protective effect in heart failure patients with type 2 diabetes.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 63 participants or records.
