Abstract

Global longitudinal strain (GLS) measured by 2-dimensional longitudinal speckle-tracking echocardiography may be a more sensitive measure of left ventricular (LV) mechanics than conventional LV ejection fraction (EF) to characterize adverse post-ST-segment elevation myocardial infarction (STEMI) remodeling. The aim of the present evaluation was to compare changes in LV GLS in patients with versus without diabetes after the first STEMI. Patients with first STEMI and diabetes (n = 143; age 64 ± 12 years; 68% men; 50% left anterior descending artery as culprit vessel) and 290 patients with first STEMI and without diabetes matched on age, gender, and infarct location were included. LV volumes and function and 2-dimensional LV GLS were measured after primary percutaneous coronary intervention (baseline) and at 6-month follow-up. At baseline, patients with and without diabetes had similar LVEF (46.8 ± 0.7% vs 48.0 ± 0.5%, p = 0.19) and infarct size (peak cardiac troponin T: 3.1 [1.2 to 6.5] vs 3.7 [1.3 to 7.3] μg/l, p = 0.10; peak creatine phosphokinase:1,120 [537 to 2,371] vs 1,291 [586 to 2,613] U/l, p = 0.17), whereas LV GLS was significantly more impaired in diabetic patients (-13.7 ± 0.3% vs -15.3 ± 0.2%, p <0.001). Although dia...Continue Reading
