Disturbances of myocardial perfusion are mostly due to obstructive coronary atherosclerosis. The shape of the narrowed lumen is polymorphic. The localization of severe stenoses is not influenced by risk factors. Atherosclerotic changes are more frequent in the coronary arteries than in their large branches. There is a good agreement between the localization and the size of the infarct and the poststenotic or postocclusive perfusion area. As a rule there are only few atherosclerotic lesions within samll intramural arteries and arterioles of the myocardium. We could not find a positive correlation between the extent of sclerotic changes in large coronary arteries and arterioles.
心肌灌注紊乱主要归因于阻塞性冠状动脉粥样硬化。狭窄管腔的形状呈多形性。严重狭窄的定位不受危险因素影响。冠状动脉粥样硬化改变比其大分支更常见。梗死的定位和大小与狭窄后或闭塞后灌注区域之间存在良好的一致性。通常，心肌内小动脉和微动脉内只有少数粥样硬化病变。我们未发现大冠状动脉和小动脉硬化改变程度之间存在正相关。
