Cardiometabolic Risk and Cardiovascular Disease in Young Women With Uterine Fibroids

Abstract

Uterine fibroids are associated with hypertension and cardiometabolic risk factors, yet the onset and severity of cardiovascular disease (CVD) in women with fibroids remain understudied. We used data from the National Health and Nutrition Examination Survey to assess the association between uterine fibroids, cardiometabolic risk, and CVD (ischemic heart disease, heart failure, and stroke). Among 5,552 women aged 20-54 years in our sample. Hypertension was more common in those diagnosed with fibroids (n=700; 33.4% vs. 15.3% in controls, p<0.001), but these women were also older (44 (SD=7) years vs. 35 (SD=10) years). When stratified by median age, women aged 35 or younger with fibroids (n=97) were more likely than controls (n=2771) to have hypertension (14.1% vs. 2.4%), obesity (51.5% vs. 32.5%), and diabetes mellitus (4.8% vs. 1.9%). Women older than 35 with fibroids also had higher cardiometabolic risk and rates of CVD than controls (8.5% vs. 4.5%). The odds ratio of CVD in women with fibroids, compared to the controls, was 3.10 with 95% confidence interval (CI) of 2.21 to 4.34. The odds ratio decreased to 1.63 (95%CI: 1.11 to 2.38) after adjusting for age, BMI, African ancestry, fasting plasma glucose, cholesterol, education, smoking history, and postmenopausal status and to 1.60 (95%CI: 1.08 to 2.37) after further adjusting for systolic blood pressure. These data indicate that uterine fibroids are associated with a worse cardiovascular risk profile, including hypertension, in relatively young women, leading to early CVD. A women-specific research agenda is urgently needed to study the nature of these associations and design preventive strategies to prevent cardiovascular events in young women with fibroids.
