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 ...
七、超声心动图观察的重点 The abnormalities in wall motion associatedwith ischemia are characterized by • Diminished or absent inward endocardialmotion • Impaired systolic myocardial thickening (inthe normal condition it is gre...
The resulting ischemia (restriction in blood supply) and ensuing oxygen shortage, if left untreated for a sufficient period of time, can cause damage or death (infarction) of heart muscle tissue (myocardium). Classical symptoms of acute myocardial infarction include sudden chest pain (typically ...
Dec et al. found that only 5.4% of 146 patients suffered from myocardial ischemia or infarction within the first 6 months following LT [37]. Patel et al. conducted a retrospective study of LT patients who were evaluated preoperatively with coronary angiography and found that only 3.9% of 283...

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
Myocardial infarction (MI) (ie, heart attack) is the irreversible death (necrosis) of heart muscle secondary to prolonged lack of oxygen supply (ischemia). Approximately 1.5 million cases of MI occur annually in the United States. See the images below. Acute myocardial infarction, reperfusion type...
acute myocardial infarction (AMI) and normoglycaemia was not achieved [7]. Recently, early management of dysglycaemia in acute myocardial ischemia has been studied. Selker et al. have shown prehospital glucose- insulin-potassium to decrease hospital mortality and cardiac arrest incidence of patient...
