Left ventricular systolic dysfunction predicts long-term major microvascular complication outcomes in type 1 diabetes. The Pittsburgh Epidemiology of Diabetes Complications (EDC) study of childhood onset diabetes.


ABSTRACT: OBJECTIVES:We aimed to assess association between abnormal LVEF, in the absence of coronary artery disease (CAD), and 25-year incidence of major outcomes of diabetes (MOD) in a cardiology substudy of the Pittsburgh Epidemiology of Diabetes Complications cohort of childhood-onset type 1 diabetes. METHODS:115 normotensive type 1 diabetes individuals without known CAD, underwent a baseline exercise radionuclide ventriculography. Abnormal LVEF was defined as a resting ejection fraction <50% or a failure to increase ejection fraction with exercise by >5% (men) or a fall in ejection fraction with exercise (women). Cox proportional hazards models were used to predict the composite endpoint of MOD (first instance of major CAD, stroke, end-stage renal disease, blindness, amputation or diabetes-related death). RESULTS:Mean baseline age was 28 and diabetes duration 19?years. In a mean follow-up of 19?years, 50 MOD events were identified. Allowing for established risk factors at baseline, abnormal LVEF (n?=?22) independently predicted MOD incidence (HR?=?2.12, 95% CI: 1.12-4.00, p?=?0.022) but not major CAD (HR?=?1.33, 95% CI: 0.53-3.33, p?=?0.539). CONCLUSIONS:An abnormal LVEF may identify diabetic cardiomyopathy and predict long term risk of MOD (but not CAD alone) in type 1 diabetes individuals, consistent with it reflecting microvascular disease.
