Sun Q, Wang Q, Wang X, et al. - Among 2,019 individuals, aged ≥ 40 years, who were free of stroke and living in rural communities in China, researchers conducted this population-based study to examine the prevalence and cardiovascular risk factors (CRFs) of asymptomatic intracranial atherosclerotic stenosis (aICAS). Through face-to-face interviews, physical examination, and laboratory test, data on demographics, CRFs, and health conditions were gathered in October 2017-May 2018. Data reported that aICAS was detected in 153 persons of the 2019 candidates. It was noted that aICAS' overall prevalence was 7.6%, and moderate-to-severe aICAS prevalence was 5.0%. Among rural-dwelling middle-aged and older Chinese people, asymptomatic ICAS is common. The authors concluded that aICAS is strongly associated with hypertension, diabetes, overweight or obesity and high hypersensitive C-reactive protein, particularly when coexisting.
