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...

In the healthy individual the heart can tolerate large increases of workload for ...

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...
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...
Sleep disorders increase the risk and mortality of heart disease, but the brain-heart interaction has not yet been fully elucidated. Cuproptosis is a copper-dependent type of cell death activated by the excessive accumulation of intracellular copper. Her

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 ...
Infarction, death of tissue resulting from a failure of blood supply, commonly due to obstruction of a blood vessel by a blood clot or narrowing of the blood-vessel channel. The dead tissue is called an infarct. Myocardial infarction (heart attack)—deat
