Correlation of serum average hGH and IGF-1 x ULN level of acromegalic patients with cardiovascular data and autonomic neuropathy parameters.

Abbreviations: 30/15 ratio, immediate heart rate response to standing; AN, autonomic neuropathy; BP: blood pressure; EDD: left ventricular end diastolic diameter; EF: ejection fraction; ESD: left ventricular end systolic diameter; hGH: human growth hormone; IGF-1: insulin-like growth factor-1; ULN: upper limit of normal value; IVS: interventricular septum; PW: posterior wall of left ventricle; QTc: frequency corrected QT interval; QTd: QT dispersion; STVQT: short-term variability of QT interval; n = 30 for each number of XY pairs,
*P<0.05 for correlation.
