Related to Myocardial ischemia/infarction:subendocardial infarction congestive heart failure congestive heart failure,inability of the heart to expel sufficient blood to keep pace with the metabolic demands of the body. In the healthy individual the heart can tolerate large increases of workload for ...

An acute coronary syndrome results in a sudden reduction of blood flow to the myocardium. In the case of ST-elevation myocardial infarction (STEMI), this is usually caused by the acute rupture of atherosclerotic plaque and thrombotic obstruction of a coronary artery. Non-STEMI (NSTEMI) may be ...
The latter is presumed to result from myocardial ischemia followed by repair. Cats with end-stage HCM appear to be particularly prone to atrial thrombosis and aortic thromboembolism. Sign in to download full-size image Figure 32. End-stage (‘burn out’) HCM in a cat. Note severe dilation ...
ST Elevation and non-ST Elevation MIs When myocardial blood supply is abruptly reduced or cut off to a region of the heart, a sequence of injurious events occur beginning with ischemia (inadequate tissue perfusion), followed by necrosis (infarction), and eventual fibrosis (scarring) if the bloo...
In myocardium, such stimuli include changes in hemodynamic state such as pressure and volume overload or damage to the heart such as ischemia and reperfusion. After myocardial infarction, the heart undergoes structural adaptations that ultimately alter left ventricular size and shape, a process ...
Extensive research during the last decade demonstrated that a single systemic administration of -erythropoietin (EPO) lead to significant attenuation of myocardial infarction (MI) induced in animals, mostly small rodents, either by a myocardial ischemia followed by reperfusion or by a permanent ligation...
During approximately 2 weeks, the necrosis heals by fibrotic scar from the periphery toward the center of ischemia. This scar matures and remodels within 2 months following the myocardial infarction [1]. Ventricular arrhythmias complicate all phases of myocardial infarction and they can result in a...
Separation of the media by hemorrhage with or without an associated intimal tear is termed coronary artery dissection. The medial separation forces the intimal-medial layer (wall of the true channel) toward the true coronary lumen and produces distal myocardial ischemia/infarction (see fig.56f and...
