ABSTRACT
BACKGROUND AND PURPOSE:
The incidence of ischaemic stroke has increased or remained high in China; however, little population-based evidence is available on the incidence and survival of lacunar infarction (LAC). We examined the incidence of LAC in a northern Chinese (Beijing) population and monitored survival.METHODS:
A prospective registry population-based study was conducted over a 6-year period in a general, unselected, and representative community in Beijing with approximately 100,000 long-term permanent residents. All first-ever stroke cases were registered.RESULTS:
A total of 1184 patients with ischaemic stroke were identified; 36.9% (437 cases) were classified as LAC. Age-standardized incidence rates of LAC ranged from 24.0 to 51.3/100,000 with an average rate of 35.3/100,000 during study period. The incidence of LAC increased with age before 70 years. The incidence of non-LAC increased with age. There were no significant differences in crude incidence of LAC between men and women (78.4/100,000 vs. 75.4/100,000). The incidence of non-LAC was significantly higher in men than in women (155/100,000 vs. 107/100,000, P < 0.001). The 28-day case fatality proportions were significantly lower in patients with LAC (0.5%) versus non-LAC (14.9%). One year after acute stroke onset, the survival rates between LAC and non-LAC were similar.CONCLUSION:
LAC is a common stroke subtype in Northern China. Men or the elderly are more likely to have non-LAC. Long-term survival following LAC is similar to non-LAC patients.
