摘要
目的：探讨原发性高血压(essential hypertension，EH)病程在不同性别中对非瓣膜病心房颤动(non-valvular atrial fibrillation，NVAF)相关的首次血栓栓塞风险的影响。方法：连续纳入2010年1月1日至2018年12月31期间住院且年龄≥16岁的心房颤动患者进行回顾性分析。以370例首次血栓栓塞的NVAF患者为病例组，2 002例无血栓栓塞的NVAF患者为对照组。将所有研究对象按照无EH，EH病程≤10年、EH病程>10年及性别分为参照组(无EH的女性)，无EH的男性组(无EH的男性)，EH病程≤10年的女性组，EH病程>10年的女性组，EH病程≤10年男性组及EH病程>10年的男性组。采用logistic回归分析各组间的首次血栓栓塞风险，同时采用相加模型和相乘模型评价EH病程与性别在首次血栓栓塞中的交互作用。校正的因素有近期心力衰竭、年龄、2型糖尿病、血管疾病(心肌梗死、动脉狭窄)、血清肌酐、PT国际标准化比值(international normalized ratio，INR)、服用新型口服抗凝剂。结果：经多因素校正后与参照组相比，无EH男性组OR为1.40(95%CI：1.00~1.96，P=0.0048)，EH病程≤10年的女性组OR为2.49(95%CI：1.74~3.55，P<0.001)，EH病程>10年的女性组OR为1.93(95%CI：1.00~3.72，P=0.048)；EH病程≤10年的男性组OR为2.56(95%CI：1.75-3.76，P<0.001)，EH病程>10年的男性组OR为4.42(95%CI：2.54~7.70，P<0.001)。当EH病程>10年，超额相对危险度为2.35(95%CI：0.01~4.68)。EH病程与性别在logistic回归中的乘积项P始终>0.05。结论：EH病程与性别在NVAF相关的首次栓塞中存在相加交互作用。在NVAF患者中，合并EH病程>10年的男性发生栓塞风险最高，约为无EH女性的4倍。

Abstract
Objective: To evaluate the risk of non-valvular atrial fibrillation (NVAF) related initial thromboembolism for different duration of essential hypertension (EH) among different sex. Methods: A total of 370 cases and 2 002 controls were retrospectively analyzed with Logistic regression. According to different sex and duration of EH, the patients were divided into a reference group (non-EH women), a non-EH men group, a women with duration of EH ≤10 years group, a women with duration of EH >10 years group, a men with duration of EH ≤10 years group, and a men with duration of EH >10 years group. We evaluated the interactions with the measures of effect modification on both additive (relative excess risk due to interaction, RERI) and multiplicative scales. Results: Compared with the reference group, the multivariable-adjusted OR (95% CI) was 1.40 (1.00–1.96) in the non-EH men group, 2.49 (1.74–3.55) in the women with duration of EH ≤10 years group, 1.93 (1.00–3.72) in the women with duration of EH>10 years group, 2.56 (1.75–3.76) in the men with duration of EH ≤10 years group and 4.42 (2.54–7.70) in the men with duration of EH>10 years group. RERI (95% CI) is 2.35 (0.01–4.68) in the men with duration of EH >10 years group, with significant difference. But there is no interaction between duration of EH and sex on multiplicative scale. Conclusion: Duration of EH interacts with sex in initial thromboembolism on an additive scale. The risk of initial thromboembolism for NVAF men with duration of EH >10 years is almost 4 times of that for non-EH women. NVAF men with duration of EH >10 years may further benefit from more aggressive strategy of anticoagulation.
