Earlier age at menopause is widely considered to be associated with an increased risk of cardiovascular disease. However, the underlying mechanisms of this relationship remain undetermined. Indications suggest that anti-Müllerian hormone (AMH), an ovarian reserve marker, plays a physiological role outside of the reproductive system. Therefore, we investigated whether longitudinal AMH decline trajectories are associated with an increased risk of cardiovascular disease (CVD) occurrence.
This study included 3108 female participants between 20 and 60 years of age at baseline of the population-based Doetinchem Cohort. Participants completed ≥1 of 5 consecutive quinquennial visits between 1987 and 2010, resulting in a total follow-up time of 20 years. AMH was measured in 8507 stored plasma samples. Information on total CVD, stroke, and coronary heart disease was obtained through a hospital discharge registry linkage. The association of AMH trajectories with CVD was quantified with joint modeling, with adjustment for age, smoking, oral contraceptive use, body mass index, menopausal status, postmenopausal hormone therapy use, diastolic blood pressure, total cholesterol, high-density lipoprotein cholesterol, and glucose levels.
By the end of follow-up, 8.2% of the women had suffered from CVD, 4.9% had suffered from coronary heart disease, and 2.6% had experienced a stroke. After adjustment, each ng/mL lower AMH level was associated with a 21% higher risk of CVD (hazard ratio, 1.21; 95% confidence interval, 1.07-1.36) and a 26% higher risk of coronary heart disease (hazard ratio, 1.25; 95% confidence interval, 1.08-1.46). Each additional ng/mL/year decrease of AMH was associated with a significantly higher risk of CVD (hazard ratio, 1.46; 95% confidence interval, 1.14-1.87) and coronary heart disease (hazard ratio, 1.56; 95% confidence interval, 1.15-2.12). No association between AMH and stroke was found.
These results indicate that AMH trajectories in women are independently associated with CVD risk. Therefore, we postulate that the decline of circulating AMH levels may be part of the pathophysiology of the increased cardiovascular risk of earlier menopause. Confirmation of this association and elucidation of its underlying mechanisms are needed to place these results in a clinical perspective.
更早的绝经年龄被广泛认为与心血管疾病风险增加有关。然而,这种关系的潜在机制仍未确定。有迹象表明,抗苗勒氏管激素(AMH),一种卵巢储备标志物,在生殖系统之外发挥着生理作用。因此,我们研究了纵向 AMH 下降轨迹是否与心血管疾病(CVD)发生风险增加有关。
这项研究包括了 3108 名年龄在 20 至 60 岁之间的女性参与者,她们是人群为基础的多滕坎姆队列的基线参与者。参与者在 1987 年至 2010 年间完成了 5 次连续的 5 年随访中的至少 1 次,总随访时间为 20 年。在 8507 份储存的血浆样本中测量了 AMH。通过医院出院登记处的链接获得了总 CVD、中风和冠心病的信息。通过联合建模来量化 AMH 轨迹与 CVD 的关系,调整了年龄、吸烟、口服避孕药使用、体重指数、绝经状态、绝经后激素治疗使用、舒张压、总胆固醇、高密度脂蛋白胆固醇和血糖水平。
在随访结束时,8.2%的女性患有 CVD,4.9%的女性患有冠心病,2.6%的女性患有中风。调整后,AMH 水平每降低 1ng/ml,CVD 的风险就会增加 21%(风险比,1.21;95%置信区间,1.07-1.36),冠心病的风险增加 26%(风险比,1.25;95%置信区间,1.08-1.46)。AMH 每年每增加 1ng/ml,CVD 的风险显著增加(风险比,1.46;95%置信区间,1.14-1.87)和冠心病(风险比,1.56;95%置信区间,1.15-2.12)。AMH 与中风之间没有关联。
这些结果表明,女性的 AMH 轨迹与 CVD 风险独立相关。因此,我们假设循环 AMH 水平的下降可能是绝经年龄较早导致心血管风险增加的病理生理学的一部分。需要确认这种关联并阐明其潜在机制,以便将这些结果置于临床视角下。
