Abstract
It was aimed to calculate QT intervals in patients with acromegaly and to reveal its correlation between QT intervals, and growth hormone and insulin like growth factor-1. Forty-one patients with acromegaly were enrolled into the study. Another 41 individuals with similar features, such as comorbid diseases, age and sex constituted the control group. The electrocardiographies of patients with acromegaly were evaluated at the baseline and after the follow-up. Only one electrocardiography was performed for controls. QT maximum, QT minimum, QT dispersion, corrected QT maximum, corrected QT minimum and corrected QT dispersion were calculated. Baseline QT maximum, QT dispersion, corrected QT maximum and corrected QT dispersion were significantly longer than the values of controls. Corrected QT maximum and corrected QT dispersion were significantly shorter after the follow-up, compared to the baseline in patients. QT maximum, QT dispersion, corrected QT maximum and corrected QT dispersion after the follow-up were not statistically different from the values of controls. Except the negative correlation between growth hormone and corrected QT dispersion in patients after the follow-up, no other correlation was detected between QT values and growth hormone or insulin like growth factor-1 levels. Corrected QT dispersion was found to be related with the disease duration in patients. For acromegaly patients, it is important to detect clinical predictors of cardiac arrhytmias. QT dispersion is considered a beneficial predictor for ventricular arrhytmias. When compared to controls, prolonged QT intervals were determined in our acromegalic patients. We consider that QT intervals may also be utilized in the evaluation of increased cardiovascular risk in patients with acromegaly.
