Heart attacks and myocardial ischemia can be diagnosed by electrocardiogram (EKG). Some of the changes are typical, others are more subtle, and none of the changes are completely sensitive or specific. Additionally, myocardial infarctions demonstrate typical changes over time, or "evolve" in ...
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...
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...
Molecular mechanisms associated with the loss of cardiomyocytes during myocardial infarction (MI) and ischemia-related cardiac diseases are not yet fully understood. Nogo-C is an endoplasmic reticulum protein ubiquitously expressed in tissues including in the heart, however, the cardiac function of Nogo...

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...
However, these entities can also be associated with myocardial infarction in case of clinical evidence of acute myocardial ischaemia with rise and/or fall of cardiac troponin. Table 1. Elevations of cardiac troponin values because of myocardial injury Injury related to primary myocardial ischaemia ...
