Impact of polyvascular disease with and without co-existent kidney dysfunction on cardiovascular outcomes in diabetes: A post hoc analysis of EMPA-REG OUTCOME.
Abstract
Abstract Aim To determine the relationship between polyvascular disease and risk of hospitalization for heart failure (HHF) and cardiovascular (CV) death in the EMPA‐REG OUTCOME population, and the relationship of kidney dysfunction co‐existent with polyvascular disease on CV/heart failure (HF) outcomes. Materials and Methods Patients with type 2 diabetes and atherosclerotic CV (ASCVD) received empagliflozin 10, 25 mg or placebo. Post hoc, subgroups were analyzed by one versus two or more vascular beds, and the estimated glomerular filtration rate ([eGFR] < vs. ≥60 mL/min/1.73 m 2 ) at baseline. The empagliflozin arms were pooled. Time to CV death, HHF, CV death (excluding fatal stroke) or HHF, all‐cause mortality (ACM) and 3‐point major adverse CV events (3P‐MACE) were assessed using multivariable Cox regression models. Results Baseline characteristics (N = 6959) within subgroups were balanced between treatment groups. In the placebo group, two or more versus one vascular bed increased HHF risk (1.59 [95% confidence interval 1.02, 2.49]), CV death (2.17 [1.52, 3.09]), CV death/HHF (1.79 [1.32, 2.43]), ACM (1.95 [1.44, 2.64]) and 3P‐MACE (1.76 [1.36, 2.27]). Hazard ratios for those with polyvascular disease/kidney dysfunction (vs. 1 vascular bed/eGFR ≥60 mL/min/1.73 m 2 ) were HHF 2.80 (1.46, 5.36), CV death 3.10 (1.87, 5.13), CV death/HHF 2.71 (1.74, 4.23), ACM 2.59 (1.67, 4.02) and 3P‐MACE 2.62 (1.82, 3.77). Empagliflozin reduced the risk of all outcomes across subgroups.…
How strong is the evidence?
Evidence Hub reads this as a secondary / pooled analysis, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 6,959 participants or records.
