ABSTRACT
Objective: To describe echocardiographic abnormalities in patients with acromegaly.
Study design: Observational, prospective, cross-sectional.
Material and methods: Twenty-two patients › 18 years of age with a diagnosis of GH-secreting pituitary adenoma were assessed using echocardiogram.
Results: Six microadenomas and 16 macroadenomas were demonstrated. There were 15 females and seven males (average age 47 years; range: 22–76). Twenty were operated (90%). Biochemical disease status was as follows: 17 active, four cured and one controlled with OCT LAR. Time of evolution of signs and symptoms of acromegaly was 7.1 years (range: 1-30). Average age at diagnosis was 40 years (range: 19-60). The most representative echographic results were concentric left ventricular hypertrophy (six patients, four with systemic arterial hypertension, SAH) and mild dilatation (one patient with SAH). Systolic dysfunction was shown in one asymptomatic patient (fractional shortening ‹ 29% and FEVI 45%). Ten patients had diastolic dysfunction. Valvular involvement included mild mitral insufficiency (five patients) and mild tricuspid insufficiency (seven patients). Expanded left atrium was demonstrated in five patients (three with SAH). In two patients, three chambers were affected and four chambers in one patient. One patient had thickened intraventricular septum without hypertension.
Conclusions: Cardiac abnormalities in acromegaly are considered the major determinant of mortality and reduced life expectancy. Expansion of cardiac cavities (50%), diastolic dysfunction (45%), valvulopathy (31%) and left ventricular hypertrophy (27%) were the most frequent findings, demonstrating the importance of early detection and control of acromegaly to avoid cardiovascular repercussions.
