背景と目的:
これまでの研究では,血栓溶解療法後の機能的転帰が男性よりも女性の方が悪いかどうかについて,相反する結果が報告されている。本研究では,中国人急性虚血性脳卒中患者における性差と静脈内血栓溶解療法の予後との関係を検討することを目的とした。
BACKGROUND AND PURPOSE: Previous studies have reported conflicting results as to whether women have poorer functional outcome than men after thrombolytic therapy. This study aims to investigate the relationship between sex differences and the prognosis of intravenous thrombolysis in Chinese patients with acute ischaemic stroke.
方法:
本試験に登録された患者は,中国急性虚血性脳卒中血栓溶解透析モニタリング登録試験の患者であった.主要転帰は機能的転帰不良であり、3ヵ月間の修正ランキンスコアが3~6と定義された。安全転帰は症候性頭蓋内出血(SICH)と7日以内と90日以内の死亡であった。性格差と予後の関連を評価するために、重回帰モデルを用いて潜在的共変量を補正した。さらに、発症前のランキンスコア、ベースラインのNational Institute of Health Stroke Scale(NIHSS)スコア、およびTrial of Org 10172 in Acute Stroke Treatment(TOAST)のタイプとの相互作用を統計学的に分析した。
METHODS: The patients enrolled in this study were from the Chinese Acute Ischemic Stroke Thrombolysis Monitoring and Registration study. The primary outcome was poor functional outcome, defined as a 3-month modified Rankin score of 3-6. The safe outcome was symptomatic intracranial haemorrhage (SICH) and mortality within 7 days and 90 days. Multiple Cox regression model was used to correct the potential covariates to evaluate the association between sex disparities and prognosis. Furthermore, the interaction of preonset Rankin scores, baseline National Institute of Health Stroke Scale (NIHSS) scores and Trial of Org 10172 in Acute Stroke Treatment (TOAST) types was statistically analysed.
結果:
女性541名、男性899名の計1440名の患者を募集した。ベースライン情報によると、女性は発症時の年齢が高く(66.2±11.2歳 vs 61.0±11.3歳、p<0.001)、心房細動の既往歴がある可能性が高い(25.3% vs 11.2%、p<0.001)。001)、心房細動の既往歴がある可能性が高く(25.3% vs 11.2%、p<0.001)、入院時のNIHSSスコアが高い(12.3±6.8 vs 11.6±6.7、p=0.04)。不満足な機能回復の予後解析では、男女間で有意差はなかった(45.9%対37.1%、調整後OR1.01、95%CI 0.75~1.37)。安全な転帰については、女性ではSICHと死亡の割合が比較的高いが、統計的有意差には至らなかった。性、年齢、発症前のランキンスコア、NIHSSスコア、TOAST分類、静脈内血栓溶解療法の予後との有意な相互作用は認められなかった。
RESULTS: A total of 1440 patients were recruited, including 541 women and 899 men. The baseline information indicated that women were older at the time of onset (66.2±11.2 years vs 61.0±11.3 years, p<0.001), and more likely to have a history of atrial fibrillation (25.3% vs 11.2%, p<0.001), and had a higher NIHSS score on admission (12.3±6.8 vs 11.6±6.7, p=0.04). According to the prognosis analysis of unsatisfactory functional recovery, there was no significant difference between women and men (45.9% vs 37.1%; adjusted OR 1.01, 95% CI 0.75 to 1.37). As for the safe outcome, the proportion of SICH and mortality in women is relatively high but did not reach statistical significance. There was no significant interaction with sex, age, preonset Rankin score, NIHSS score, TOAST classification and the prognosis of intravenous thrombolysis.
結論:
中国の虚血性脳卒中患者では,女性の方が高齢で発症時の重症度が高いにもかかわらず,静脈内血栓溶解療法後の予後は男性と有意差がない。
CONCLUSIONS: For Chinese patients with ischaemic stroke, although women are older and more severe at the time of onset, the prognosis after intravenous thrombolysis is not significantly different from men.
