The mechanisms of acute myocardial infarction depend on the site of myocardial infarction (MI). In anterior MI, the main factor is a large area of injury; in inferior MI, of importance is dysfunction of the papillary muscles and multiple lesions of the coronary artery in addition to the above factor. The site, the area of injury and the status of the coronary bed influence the rate, character and prognostic value of early load test criteria and contractile function of the left ventricle. In anterior MI, elevation of the ST segment is the most frequent criterion; in inferior MI, its depression. Their combination with other criteria for test discontinuation point to multiple lesions of the coronary artery. In patients with anterior MI, the ejection fraction of the left ventricle amounting to 40%, inadequate growth of AP, anginous pain and the T dominant elevation of the ST segment are unfavourable predictors, allowing the patients to be differentiated in accordance with the risk of postinfarction complications.
急性心肌梗死的机制取决于心肌梗死（MI）的部位。在前壁心肌梗死中，主要因素是大面积损伤；在下壁心肌梗死中，除上述因素外，乳头肌功能障碍和冠状动脉多发病变也很重要。梗死部位、损伤面积和冠状动脉床状态会影响早期负荷试验标准的速率、特征和预后价值以及左心室收缩功能。在前壁心肌梗死中，ST段抬高是最常见的标准；在下壁心肌梗死中，则是ST段压低。它们与其他试验终止标准相结合表明冠状动脉存在多发病变。在前壁心肌梗死患者中，左心室射血分数达40%、前壁心肌生长不足、心绞痛以及ST段T波优势抬高都是不良预测指标，可据此将患者按照心肌梗死后并发症风险进行区分。
