The uterus and the heart share a common structure and may remodel in a similar fashion, albeit temporally distinct. The authors investigated the prevalence of systemic hypertension in women with uterine leiomyomata (fibroids) and compared the prevalence in women undergoing hysterectomy for other reasons as well as in age-matched women from the National Health and Nutrition Examination Survey III (NHANES III). A total of 584 women, 205 with leiomyomata in 1999 (group A) and 379 who underwent hysterectomy for a variety of reasons in 2000 (group B) at Advocate Christ Medical Center were included. Presence of leiomyomata was confirmed by pathology. Hypertension was defined as blood pressure > or = 140/90 mm Hg or history of hypertension with or without medication use. The prevalence of hypertension in group A and B patients with leiomyomata compared with NHANES III overall was 48.6% vs. 24% (p<0.001), in African Americans 55.5% vs. 32.4% (p<0.001), and in Caucasians 51.1% vs. 23.3% (p<0.001). Leiomyomata were more frequent among hypertensive than normotensive women (57% vs. 27%). Caucasian and African-American women with leiomyomata were significantly younger and more likely to use hormone replacement therapy than others. Thus there appears to be an association between leiomyomata and hypertension, which needs to be explored in future prospective trials.
