Endothelial and Microvascular Functions in Patients With Myocardial Ischemia

Cardiovascular diseases (CVD) are responsible, throughout the world, for high mortality rates and cardiovascular morbidity. Endothelial dysfunction is the earliest marker of clinical atherosclerosis development. Human studies show that endothelial and microvascular dysfunction are independent predictors of ischemic cardiovascular events and long-term prognosis. The study´s objective is to evaluate the endothelial and peripheral microcirculation changes by venous occlusion plethysmography (VOP), nailfoldvideocapillaroscopy (NVC) and serum biomarkers in patients with myocardial ischemia detected by scintigraphy and normal coronarography.
