ARTICLE HIGHLIGHTS
Research background
Dipeptidyl peptidase-4 (DPP-4) inhibitors are a safe and efficacious treatment option in type 2 diabetes mellitus (T2DM).
Research motivation
Recently, several large, cardiovascular-outcome, randomized controlled trials (RCTs) with DPP-4 inhibitors in patients with T2DM have been published, raising some doubts on the cardiovascular efficacy and safety of this drug class.
Research objectives
Herein the authors provide the most updated and broad relevant meta-analysis by pooling data of interest from the available cardiovascular-outcome RCTs, addressing the cardiovascular efficacy and safety of this drug class.
Research methods
The authors searched PubMed and grey literature sources for all published RCTs assessing cardiovascular outcomes with DPP-4 inhibitors compared to placebo until October 2020.
Research results
Overall, DPP-4 inhibitors seem to have a neutral effect on most surrogate cardiovascular outcome endpoints, such as cardiovascular death, myocardial infarction, stroke, hospitalization for heart failure decompensation, hospitalization for unstable angina or coronary revascularization.
Research conclusions
DPP-4 inhibitors do not provide any clear cardiovascular benefit in patients with T2DM.
Notably, DPP-4 inhibitors are not associated with a significant effect on the risk for major cardiac arrhythmias, except for atrial flutter, increasing the risk by 52% compared to placebo.
Research perspectives
DPP-4 inhibitors do not provide any clear cardiovascular benefit in patients with T2DM.
