在2,772名65 - 74岁的人群中前瞻性研究了中风的意义和短暂性脑缺血发作（TIA）的相关性。研究开始时，TIA的患病率为63/1000。TIA患病率在黑人和女性中显著高于白人和男性。只有13%的TIA患者没有任何其他心血管疾病的主要证据。白色男性、黑人男性和黑人女性TIA患者的卒中发生率高于无TIA患者。白色妇女是这一趋势的一个明显例外。TIA的发生频率与卒中风险呈正相关。TIA合并高血压患者的卒中发生率高于血压正常的TIA患者。
The significance for stroke and correlates of transient ischemic attacks (TIA) were studied prospectively in a population of 2,772 persons aged 65 to 74. The prevalence of TIA at the beginning of the study was 63 per 1,000. TIA prevalence was substantially higher among blacks and women than among whites and men. Only 13% of those with TIA were free from any other major evidence of cardiovascular disease. White men, black men and black women with TIA had higher observed incidence rates of stroke than those without TIA. White women were a notable exception to this trend. There was a positive association between frequency of TIA and risk of stroke. Those with TIA and hypertension experienced higher stroke incidence rates than normotensive persons with TIA.
