对270例连续住院急性心肌梗塞(AMI)患者观察了高血压病史对老年 AMI 近期预后的影响。结果表明,老年组中有高血压病史者住院死亡率和心衰明显多于老年组中相同病史患者;老年和非老年组中有单纯高血压病史者肌酸激酶(CPK)峰值与无病史患者无明显差异,而老年组中有高血压病史患者和无病史患者的 CPK 峰值均显著低于非老年组相同病史患者(201±134对263±141;217±129对344±127IU)。提示长时间高血压引起的症状性和无症状性心肌缺血反复发作可促使侧支血管形成,老年人虽 AMI 时 CPK 峰值低,预后却较差。
The effect of the history of hypertension on the short-term prognosis of AMI was observed in 270 consecutive hospitalized patients with acute myocardial infarction (AMI). The results showed that the history of hypertension in the elderly group had significantly higher in-hospital mortality and heart failure than those in the elderly group. The peak values of the creatine kinase (CPK) in the elderly and non-elderly patients with no history of hypertension There was no significant difference between the two groups. However, the peak of CPK in elderly patients with and without history of hypertension was significantly lower than that in non-elderly patients (201 ± 134 vs. 263 ± 141; 217 ± 129 vs. 344 ± 127 IU). Suggesting that prolonged hypertension caused by recurrent symptomatic and asymptomatic myocardial ischemia can promote the formation of collateral vessels, although the elderly CPI peak AMI peak, the prognosis is poor.
