近年来,许多研究对我们了解心脏性猝死、不稳定型心绞痛与急性心肌梗塞(AMI)有重要价值。提出引起这些功能紊乱的共同机理,并根据其病理生理考虑新的推断。冠状动脉(冠脉)粥样硬化的主要作用冠脉病变(CAD)的主要不良后果是动脉粥样硬化斑。这种斑块可引起或不引起严重的管腔狭窄。如无严重狭窄,一般无心肌缺血表现;如有明显狭窄,则可发生劳力性心绞痛。由于冠脉严重狭窄血流贮备受限,当应激反应
In recent years, many studies have important value in understanding sudden cardiac death, unstable angina pectoris and acute myocardial infarction (AMI). The common mechanisms responsible for these disorders are proposed and new inferences are made based on their pathophysiology. Main Role of Coronary Artery (Coronary) Atherosclerosis The major adverse effect of coronary artery disease (CAD) is atherosclerotic plaque. This plaque can cause or not cause severe stenosis. If no serious stenosis, the general performance of myocardial ischemia; if obvious stenosis, can occur with angina pectoris. Due to severe coronary stenosis blood flow reserve is limited, when the stress response
