ABSTRACT
Objective: To describe the echocardiographic abnormalities of patients with acromegaly treated at Centro Médico Nacional «20 de Noviembre». Materials and methods: Cross-sectional and observational study of patients with acromegaly attending our clinic between February and June 2010. All subjects underwent Doppler echocardiography; clinical and biochemical characteristics of those with and without echocardiographic abnormalities were compared. Results: Thirty-five patients, 22 women (62.8%) and 13 males (32.75%), with a mean age of 52.8 ± 13 years were studied; mean disease duration was 12.9 years. Transsphenoidal surgery had been performed in 28 of the patients (80%), while 7 were waiting surgical treatment. Echocardiography revealed hypertrophy of the septum and the posterior wall in 40%. Septum thickness positively correlated with disease duration (r = 0.38, p = 0.025), history of hypertension (r = 0.51, p = 0.002) and cavernous sinus invasion on MRI (r = 0.38, p = 0.025). Diastolic dysfunction was found in 54.28% of the patients and 40% had some degree of valvular involvement. The biochemical control of acromegaly did not correlate with the echocardiographic findings. Conclusions: As expected, 40% of our patients had echocardiographic abnormalities, concentric hypertrophy of the left ventricle being the most common one. Echocardiographic findings did not correlate with the degree of biochemical control, but disease duration did, suggesting that these abnormalities are the consequence of long-term exposure to hypersomatotropinemia.REFERENCES
