Patients undergoing surgery for fibroid tumors of the uterus had significantly higher blood pressures (140.3/89.6 mm Hg) than those undergoing other gynecological procedures (129.5/83.5 mm Hg) in this institution. Though the fibroid patients were significantly older, heavier, and had fewer children, stratification on these variables failed to remove the blood pressure disparities. The incidence of cardiomegaly and of abnormalities found on intravenous pyelograms (IVP) was greater in the fibroid patients. The blood pressure difference between the groups persists after operation. The triad of obesity, fibromyomata uteri, and hypertension appears to constitute a syndrome.
