Endothelial Dysfunction in Acromegalic Patients: A Case-Control Study

Acta Endo (Buc) 2018, 14 (3): 384-388
doi: 10.4183/aeb.2018.384

Purpose. Assessing cardiovascular risk in patients with acromegaly using traditional cardiovascular risk factors is inadequate. Endothelial dysfunction seems to be a much better indicator for assessing cardiovascular risk in acromegaly. The study aims to compare from this point of view two groups of patients, with hypertension and with acromegaly. Methods. The first group consists of 54 patients with acromegaly and the second group of 64 hypertensive patients. Endothelial dysfunction was evaluated by the FMD method. The relationship between endothelial dysfunction, specific humoral markers of acromegaly and traditional cardiovascular risk factors was analysed in both groups. Results. Although the presence of cardiovascular risk factors was statistically significantly higher in the group of hypertensives (the most important were age, blood pressure, glycemia, hypertriglyceridemia and SCORE), the presence of endothelial dysfunction was higher in the acromegaly group (61.10% vs. 32.10%, p=0.02). The best correlation with endothelial dysfunction in acromegaly group was the level of GH (28.9±28 vs. 11.7±10.3, p=0.003). Conclusions. The presence of endothelial dysfunction in patients with acromegaly is highly dependent on the level of GH and traditional cardiovascular risk factors are less important. In these patients the cardiovascular risk should not be evaluated in the same way as in normal population.
