BACKGROUND: Compared to individuals without type 2 diabetes mellitus, the relative increase in cardiovascular mortality is much higher in women than in men in individuals with type 2 diabetes mellitus. METHODS: We evaluated data from 7443 individuals (3792 women, 50.9%), aged 20 to 81 years, from two independent population-based investigations, SHIP-0 and MONICA/KORA S3. We analyzed the longitudinal sex-specific associations of lipoprotein(a) with cardiovascular mortality in individuals with and without type 2 diabetes mellitus using Cox regression. RESULTS: During a median follow-up of 20.5 years (136,802 person-years), 657 participants (404 men and 253 women) died of cardiovascular causes. Among individuals without type 2 diabetes mellitus, men had a significantly higher risk for cardiovascular mortality compared to women in unadjusted model and after adjustment. On the other hand, in participants with type 2 diabetes mellitus, the risk for cardiovascular mortality was not different between men and women in the unadjusted model and after adjustment for age, body mass index, low-density lipoprotein-cholesterol, fasting status and study sample (SHIP-0, MONICA/KORA S3). Further adjustment for lipoprotein(a) concentrations had no impact on the hazard ratio (HR) for cardiovascular mortality comparing men versus women in individuals without type 2 diabetes mellitus [HR: 1.94; 95% confidence interval (CI) 1.63 to 2.32; p < 0.001]. In individuals with type 2 diabetes mellitus, however, further adjustment for lipoprotein(a) led to an increased risk for cardiovascular mortality in men and a decreased risk in women resulting in a statistically significant difference between men and women (HR: 1.53; 95% CI 1.04 to 2.24; p = 0.029). CONCLUSIONS: Women are described to have a stronger relative increase in cardiovascular mortality than men when comparing individuals with and without type 2 diabetes mellitus. Higher lipoprotein(a) concentrations in women with type 2 diabetes mellitus than in men with type 2 diabetes mellitus might partially explain this finding.
背景:与没有 2 型糖尿病的个体相比,2 型糖尿病个体的心血管死亡率的相对增加在女性中比男性更高。
方法:我们评估了来自两个独立的基于人群的调查(SHIP-0 和 MONICA/KORA S3)的 7443 名个体(3792 名女性,占 50.9%)的数据。我们使用 Cox 回归分析了脂蛋白(a)与有和没有 2 型糖尿病的个体心血管死亡率的纵向性别特异性关联。
结果:在中位随访 20.5 年(136802 人年)期间,有 657 名参与者(404 名男性和 253 名女性)死于心血管原因。在没有 2 型糖尿病的个体中,男性在未经调整的模型和调整后的模型中,心血管死亡率的风险均显著高于女性。另一方面,在患有 2 型糖尿病的参与者中,在未经调整的模型和调整年龄、体重指数、低密度脂蛋白胆固醇、空腹状态和研究样本(SHIP-0、MONICA/KORA S3)后,男性和女性的心血管死亡率风险无差异。进一步调整脂蛋白(a)浓度对无 2 型糖尿病个体中男性与女性心血管死亡率的危险比(HR)没有影响[HR:1.94;95%置信区间(CI)1.63 至 2.32;p<0.001]。然而,在患有 2 型糖尿病的个体中,进一步调整脂蛋白(a)导致男性的心血管死亡率风险增加,女性的风险降低,导致男性和女性之间存在统计学显著差异(HR:1.53;95%CI 1.04 至 2.24;p=0.029)。
结论:与没有 2 型糖尿病的个体相比,在比较有和没有 2 型糖尿病的个体时,女性描述为心血管死亡率的相对增加更强。与男性相比,患有 2 型糖尿病的女性脂蛋白(a)浓度更高,这可能部分解释了这一发现。
