实验、流行病学和临床资料提示,引起冠状动脉粥样硬化性狭窄的机制与诱致心肌缺血急性发作的机制很不相同.西方国家人群中持续高血压者冠心病的发生率高,但促使猝死和急性心肌梗塞的机制似与血压波动(而非高血压本身)的关系更大.现就冠状动脉粥样瘤的形成和冠心病临床表现的发生,分别予以讨论.冠状动脉狭窄的发生
Experimental, epidemiological and clinical data suggest that the mechanism that causes coronary atherosclerotic stenosis is very different from the mechanism that causes acute episodes of myocardial ischemia. The prevalence of coronary heart disease is high in people with persistent hypertension in western countries, The mechanisms of sudden death and acute myocardial infarction seem to be more related to fluctuations in blood pressure than to hypertension itself, and the formation of coronary atheromas and the clinical presentation of coronary heart disease are discussed separately.Coronary stenosis occurs
