Abstract
Diabetic cardiomyopathy (DCM) was defined left ventricular dysfunction in the absence of hypertension, coronary artery disease or valve disease. It involves a progression from normal heart to preclinical left ventricular diastolic and systolic dysfunction followed by overt echocardiographic evidence of left ventricular (LV) dysfunction and finally symptomatic heart failure. The objective of this case control cross sectional observational study is to assess the impact of type1 diabetes on left ventricular function using speckle tracking echocardiography, even in the asymptomatic subjects. Secondary endpoints are to determine its relation to age, duration of DM, HbA1c, obesity indices and other diabetic complications such as microangiopathies. The study population included 30 normotensive type1diabetic patients for less than 10 years without known cardiovascular disease (group A) and 30 normotensive type1diabetic patients for more than 10 years without known cardiovascular disease (group B) and 30 healthy age and sex matched volunteers
