Having vascular risk factors was associated with a 12.6% prevalence of asymptomatic middle cerebral artery stenosis, escalating from 7.2% with one risk factor to 29.6% with four.
Cross-Sectional (n=3,057)
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.
Wong et al. (Mon,) conducted a cross-sectional in Asymptomatic intracranial atherosclerosis (n=3,057). Vascular risk factors was evaluated on Middle cerebral artery stenosis. Having vascular risk factors was associated with a 12.6% prevalence of asymptomatic middle cerebral artery stenosis, escalating from 7.2% with one risk factor to 29.6% with four.
