冠心病中最为常见的一种类型就是心绞痛。心绞痛是一种临床综合症,其发生原因是冠状动脉心肌血液供应不足导致心肌急剧或短暂缺氧缺血,最终导致心肌坏死;其发病机制是因为心肌暂时性缺血缺氧,乳酸等代谢产物对心肌自主神经造成刺激,传入纤维末梢导致疼痛;临床表现是阵发性胸骨后压榨性疼痛并伴有放射性左上肢疼痛;依据其临床表现,可以分为稳定型、不稳定型和变异型心绞痛。如果不对处于心绞痛持续发作期的患者进行及时有效的救治,心绞痛可能会发展为急性心肌梗死,严重时患者的生命还会受到危及。
One of the most common types of coronary heart disease is angina. Angina is a clinical syndrome that occurs because of insufficient or insufficient blood supply to the coronary arteries leading to acute or transient myocardial hypoxia and myocardial necrosis; its pathogenesis is due to transient ischemia and hypoxia in the myocardium, metabolites such as lactate Stimulate the autonomic nerve of the heart and afferent fibers lead to pain; clinical manifestations are paroxysmal post-sternal pain and radioactive left upper extremity pain; according to its clinical manifestations, it can be divided into stable, unstable and variant Angina. If you do not promptly and effectively treat patients in the continuous episode of angina, angina pectoris may develop into acute myocardial infarction, and in serious cases the patient’s life will be endangered.
