Inappropriate microvascular constriction produced transient ST-segment elevation in patients with syndrome X.
OBJECTIVES The aim of this project was to study the responsible site(s) and underlying cardiac disease(s) of patients with transient ST-segment elevation and normal coronary angiograms. BACKGROUND Transient ST-segment elevation has been demonstrated in patients with variant angina or unstable angina. In those patients, epicardial coronary arteries, not microvessels, are always the responsible...
متن کامل[Differential characteristics of patients with acute coronary syndrome without ST-segment elevation compared to those with transient ST-segment elevation].
OBJECTIVE To evaluate different characteristics of patients with acute coronary syndrome (ACS) without ST-segment elevation compared with transient St-segment elevation. DESIGN An observational, prospective study. SETTING A 12-bed coronary care unit. PATIENTS Consecutive patients of ACS without persistent ST-segment elevation. MAIN VARIABLES OF INTEREST The population was divided intro ...
متن کاملTransient ST-Segment Elevation
AN IDEAL LESION for coronary artery bypass graft surgery is a severe proximal narrowing of a major coronary artery with a distal vessel free of severe disease. It would be helpful if it were possible to identify those patients likely to have such ideal "surgical" lesions prior to arteriography by means of the electrocardiogram. It has been proposed that the presence of transient ST-segment elev...
متن کاملPlatelet activation and microvascular injury in patients with ST-segment elevation myocardial infarction.
BACKGROUND Dual antiplatelet therapy reduces the risk of thrombotic complications after primary percutaneous coronary intervention (PCI). AIM To assess whether inhibition of platelet function attenuates microvascular damage in patients with ST-segment elevation myocardial infarction (STEMI). METHODS We studied 83 STEMI patients treated with primary PCI. Platelet aggregation was measured on ...
متن کاملStudy of the Duration, Outcomes, and Related Factors of Reperfusion Therapy in Patients with ST-Segment Elevation Myocardial Infarction
Background and Objective: One of the most important advancements regarding the care of patients with acute myocardial infarction is the administration of anti-coagulation medicines (e.g., streptokinase). However, it must be noticed that this medicine requires rapid and timely administration. Moreover, Percutaneous Coronary Intervention (PCI) is increasingly used as a method of revascularization...
