| Aims In addition to increased risk of cardiovascular disease, the prevalence of diabetic cardiomyopathy is increasingly recognized in patients with type 1 diabetes mellitus (T1DM). We aimed to identify the occurrence of subclinical markers of cardiovascular risk and cardiac dysfunction and assess their relation to clinical parameters in asymptomatic patients with T1DM. Methods and results A total of 102 patients (mean age 46 years [20-73], 62% male) with a history of T1DM ranging from 5 to 47 years underwent standard 2D and pulse-wave tissue Doppler echocardiography (Philips iE33) and computerized tomography for assessment of coronary calcium score (CACS) and visceral fat. Global peak longitudinal strain (GPLSS, speckle tracking) was calculated by offline analysis (Qlab 9.0). Whereas systolic function was preserved in all patients (LVEF > 50%), subclinical dysfunction (defined as global longitudinal peak systolic strain [GLPSS] of >-20%) was present in 39% and 66% had diastolic dysfunction. Fifty patients had a CACS above the 50th percentile according to age and gender. These patients were older, more obese, had higher levels of visceral fat, higher SBP and increased levels of LDL cholesterol. Higher CACS meant increased risk of diastolic and subclinical systolic dysfunction. However, decreased GLPSS was also detected in 30% of patients with CACS of GPLSS and CACS. Conclusion Subclinical left ventricular dysfunction and atherosclerosis were highly prevalent in asymptomatic T1DM. Abnormal GPLSS was noted with or without associated increase in CACS. Visceral fat was a strong predictor of increased CACS as well as abnormal GLPSS. |
