四种缺血性卒中复发风险评分系统的性别差异

In general, recurrence prediction of ischemic stroke relies on scoring models based on risk factors, but the overall predictive validity is barely satisfactory. Gender, as one of risk factors of recurrence, has not been included in most scoring systems yet, which might be one of the impacting factors to predictive validity. Inherent differences, such as sex hormone, between male and female may be the independent risk factors of stroke recurrence. Meanwhile, different tolerance to a specific risk factor between male and female may also affect the predictive validity; for instance, male have better tolerance to risk factors including diabetes and hypertension. Therefore, this paper makes analysis to gender differences in evaluative validity of each item and overall effect among the four major recurrence prediction scoring systems for ischemic stroke (including CHADS2 scoring system, CHA2DS2-VASc scoring system, Essen stoke risk scoring system and ABCD2 risk scoring system).
