Left ventricular mass (LV mass) and function were assessed in 16 acromegalic patients by echocardiography, and rest and exercise gated blood pool scanning (GBPS) respectively. At the time of study, five patients had active acromegaly, five were hypertensive and three had coexisting coronary artery disease. Increased LV mass was found in six (38%) patients, of whom four were hypertensive and two others had active acromegaly of long duration. One normotensive patient, who did not have coronary disease, had increased LV mass associated with persistently elevated growth hormone (GH) levels for the previous 11 years. Abnormal LV function, as detected by GBPS, occurred only in the three patients with coronary disease. Thus, acromegaly is associated with increased LV mass in hypertensive patients and normotensive patients who have prolonged elevation of GH levels prior to adequate treatment. We found no detectable impairment of LV function, at rest or exercise unless other cardiac disease was present.
