The investigators aimed to evaluate microvascular circulation with novel method: real-time myocardial contrast echocardiography in patients with type 2 diabetes and normal coronary arteries. Myocardial blood flow reserve will be determined by quantitative contrast Stress echocardiography. Diabetic individuals will be evaluate in a decompensated state (Phase 1) and after optimization of medical treatment four months later (Phase 2).
Early stages of epicardial atherosclerosis in patients with type 2 diabetes are associated with an impairment in endothelium-dependent dilation of the coronary microvasculature, indicating that the pathophysiological consequences of atherosclerosis may extend into the coronary microcirculation. The investigators will evaluate three parameters of myocardial quantification with contrast Stress echocardiography and correlate with HbA1C levels.
