Abstract
ObjectiveTo determine the incidence and prevalence of transient ischemic attack (TIA) and to evaluate its epidemiological situation in Hunan province.
MethodsSeven monitoring points were randomly selected from the province, a total of 8 311 subjects aged≥50 years were then chosen by stratified sampling. The cases counted in prevalence was defined as patients diagnosed before 24:00 o'clock August 31st, 2013, and the new diagnosis for incident counting was defined as those diagnosed between 00:00 September 1st, 2012 and 24:00 August 31st, 2013.
ResultsAmong all 8 311 screened subjects, the number of TIA patients was 24 (288.8 per 100 000 people), the incidence of TIA was 7 (85.2 per 100 000 people). Standardized prevalence and incidence were 283.2 and 82.4 per 100 000 respectively using 2010 China census population. Among them, the standardized incidence rate of female was higher than that of male (114.8 per 100 000 person-years vs. 48.8 per 100 000 person-years), and the prevalence rate of males was higher than that of female (288.2 per 100 000 people vs. 273.2 per 100 000 people). Hypertension is the most important risk factor for TIA (55.2%).
ConclusionThe incidence and prevalence of TIA in Hunan province are higher than the national average. Hypertension is the main risk factor.
