We used transcranial Doppler to screen 3,057 patients who had at least one vascular risk factor of hypertension, diabetes, or hyperlipidemia and found 385 (12.6%) had middle cerebral artery stenosis. Elderly, hypertension, diabetes, and hyperlipidemia were associated factors. The prevalence escalated quadratically with increasing number of associated factors: from 7.2% for one, to 29.6% for four associated factors. Asymptomatic middle cerebral artery stenosis is common in patients with vascular risk factors.
我们使用经颅多普勒对3057例至少有高血压、糖尿病或高脂血症其中一种血管危险因素的患者进行筛查，发现385例（12.6%）存在大脑中动脉狭窄。年龄较大、高血压、糖尿病和高脂血症是相关因素。患病率随相关因素数量的增加呈二次方上升：从一种相关因素的7.2%升至四种相关因素的29.6%。无症状大脑中动脉狭窄在有血管危险因素的患者中很常见。
