Brief summary
Left ventricular remodeling is a common complication in patients with ST-elevation myocardial infarction (STEMI ) and may lead to heart failure. Hemodynamic, metabolic and inflammatory mechanisms are involved in this pathophysiological process. Recent data demonstrated that remote, noninfarct-related region of the myocardium is also implicated. There is no data about the assessment of coronary endothelial function or myocardial fibrosis in the remote zone in patients with STEMI . The correlation between these parameters and left ventricular remodeling is not known.
Interventions
Coronary endothelial function is assessed using (15)-O water positron emission tomography and cold pressor test . The response to the test is defined by the percentage increase myocardial blood flow . Assessment of fibrosis, inflammation an endothelial function is performed using biomarkers.
