Abstract

Regional left ventricular (LV) myocardial functional changes in early diabetic cardiomyopathy have not been well documented. LV multidirectional strain and strain rate analyses by 2-dimensional speckle tracking were used to detect subtle myocardial dysfunction in 47 asymptomatic, male patients (age 57 ± 6 years) with type 2 diabetes mellitus. The results were compared to those from 53 male controls matched by age, body mass index, and body surface area. No differences were found in the LV end-diastolic volume index (40.7 ± 8.9 vs 44.1 ± 7.8 ml/m2, p = NS), end-systolic volume index (16.0 ± 4.8 vs 17.8 ± 4.3 ml/m2, p = NS), ejection fraction (61.0 ± 5.5% vs 59.8 ± 5.3%, p = NS). The transmitral E/A (0.95 ± 0.21 vs 1.12 ± 0.32, p = 0.007) and pulmonary S/D (1.45 ± 0.28 vs 1.25 ± 0.27, p = 0.001) ratios were more impaired in the patients with diabetes mellitus. Importantly, the diabetic patients had impaired longitudinal, but preserved circumferential and radial systolic and diastolic, function. Diabetes mellitus was an independent predictor for longitudinal strain, systolic strain rate and early diastolic strain rate on multiple linear regression analysis (all p <0.001). In conclusion, the LV longitudinal systolic and diastolic function were impaired, but the circumferential and radial functions were preserved in patients with uncomplicated type 2 diabetes mellitus.
