Warty projections arise from the deposition, while subendocardial lesions may induce irregular thickenings called MacCallum plaques.
3.
Totally occluded arteries were found in 29 of 57 patients in the group without subendocardial infarctions from becoming transmural infarctions.
4.
For non-transmural ischemia ( subendocardial ischemia ) injured cells are closer to the inside of heart wall, resulting in a systolic injury current.
5.
At this point there may be signs of " ventricular strain pattern " ( ST segment depression and T wave inversion ) on the EKG, suggesting subendocardial ischemia.
6.
Side effects of " oral " minoxidil may include swelling of the face and extremities, rapid and irregular heartbeat, lightheadedness, cardiac lesions, and focal necrosis of the papillary muscle and subendocardial areas of the left ventricle.
7.
Due to the high contrast between the blood pool and the myocardium it is common to get what looks like a thin subendocardial area of ischaemia called the Gibbs artifact, this however, is less common with newer technology allowing higher resolution imaging.
8.
These arteries, when healthy, are capable of autoregulation to maintain coronary blood flow at levels appropriate to the needs of the heart attack . ( See also : circulatory system . ) The coronary arteries that run deep within the myocardium are referred to as subendocardial.
9.
In another often-cited study, Freedman focused on the issue of MI prevention by selecting 121 patients with severe single vessel disease . 64 had Q-wave infarction and 57 did not; 32 had unstable angina or subendocardial infarction . 74 totally occluded vessels and 47 subtotally occluded vessels were identified in this study, and the presence of total occlusion was the most significant predictor of the existence of collaterals . 63 of 74 ( 85 % ) of the " totalled " vessels were accompanied by evidence of collaterals, compared to 8 of 47 ( 17 % ) of the subtotalled vessels ( p = 0.001 ).
