本文研究显示变异型心绞痛无论从发作的诱因和轻重、发作时心率血压的变化和ECG上ST段是否抬高或压低及发作后T波的改变等方面都有较大差异。8例AMI中5例心绞痛史不足一个月,提示及早诊治可减少AMI的发生率。
This study shows that variant angina pectoris has a great difference in terms of the causes and severity of the episode, the change of heart rate and blood pressure at the time of attack, whether the ST segment is elevated or depressed on ECG, and the change of T wave after the onset of stroke. 5 cases of AMI in 8 cases history of angina less than one month, suggesting that early diagnosis and treatment can reduce the incidence of AMI.
