About

Diabetes Mellitus type 1 is characterized by an absolute insulin deficiency caused by T-cell-mediated autoimmune destruction of pancreatic β-cells . It is the predominant form of diabetes mellitus during childhood and adolescence. Hyperglycemia is a major cause of vascular and neuropathic complications that are seen in patients with diabetes mellitus type 1.

Full description

Cardiovascular risk factors remain the most controversial chronic complication in diabetes mellitus type 1 Neuropathy in diabetes mellitus type 1 can lead to abnormalities in the response of the coronary vasculature to sympathetic stimulation, which may manifest clinically as resting tachycardia or bradycardia, exercise intolerance, orthostatic hypotension, loss of the nocturnal decline in blood pressure, or silent myocardial ischemia on cardiac testing. These abnormalities can lead to delayed presentation of cardiovascular disease. An early indicator of cardiac autonomic neuropathy is reduced heart rate variability, which can be assessed qualitatively in the clinic. Limited data suggest silent myocardial ischemia is more common in the presence of cardiac autonomic neuropathy . Cardiovascular mortality is a leading cause of death in Type 1 diabetic patients, in particular in patients with nephropathy.QT dispersion defined as the difference between maximal and minimal QT intervals from different electrocardiogram leads ( the QT interval was defined as the time between the first deflection from the isoelectric PR interval and the visual return of the T wave to the T-P segment ) ,Because these electrocardiogram abnormalities may confer an increased risk of ventricular arrhythmias and sudden cardiac death , early identification may have prognostic value .
