Effects of glucagon-like peptide-1 agents on left ventricular function: systematic review and meta-analysis.

The cardiovascular safety of many glucagon-like peptide-1 agents (GLP-1 agents) is unclear. In this study, we assess the effects of the GLP-1 agents on left ventricular function in patients with type 2 diabetes (T2DM) and/or cardiovascular disease (CVD).
