摘要
目的 :调查我国心肌梗塞 (MI)病人合并无症状性脑梗塞 (AI)的发生率 ,探讨其 CT表现特点和危险因素。方法 :对 84例 MI患者和 75例对照者行头颅 CT扫描。结果 :84例 MI患者中 ,检出 AI2 3例 ,发生率为2 7.38% ;对照组 75例 ,检出 AI者 3例 ,检出率为 4.0 % ,两组间有非常显著的差异 (P<0 .0 0 1)。腔隙性梗塞占 MI患者伴发 AI的 86 .96 % ,皮质梗塞占 8.7% ,腔隙性梗塞最多见于基底节 (75 % )。伴高血压病的 MI患者 AI发生率显著高于无高血压病者 (P<0 .0 5 )。结论 :我国 MI病人中 AI是相当常见的 ,高血压是 MI伴发 AI的危险因素。
Objective:To investigate the incidence of asymptomatic infarction (AI) in Chinese patients with myocardial infarction(MI)and to explore the computed tomographic(CT) characteristics and risk factors of AI.Methods:A brain CT scan was performed in 75 controls and in 84 MI patients free of any history of stroke and unrelated to the symptoms and signs of the index stroke.Results:AI was observed in 23 (27 38%) of the 84 patients and 3 (4 0%) of the 75 controls.There was a significant difference of the incidence of AI between the two groups( P <0 001).Of all AIs in MI patients,lacunar infarct accounted for 86 96%,cortical infarct accounted for 8 7%.Silent lacunae were most often located in the basal ganglia(75%).The incidence of AI in MI patients with hypertension is higher than that of AI in MI patients without hypertension( P <0 05).Conclusion:In Chinese patients with MI,AIs are fairly common.Hypertension is the risk factor for AI in patients with MI.
