Objective: The risk of aortic dissection is 100-fold increased in Turner syndrome (TS). Increased blood pressure (BP) and heart rate is present as well as an increased risk of ischemic heart disease and diabetes. This study aimed to prospectively assess heart rate variability (HRV) in TS and its relation to aortic dimensions.Methods: Adults with TS (n=91, aged 37.4±10.4 years) recruited through the Danish National Society of Turner Syndrome...

Background: Aortic dissection causes excess mortality in Turner syndrome, and this increased risk is associated with aortic dilation, congenital cardiovascular abnormalities, karyotype, and blood pressure. But risk factor identification is inadequate, and the natural course of aortopathy in Turner syndrome is poorly investigated.Design and methods: Prospective follow-up study in women with Turner syndrome (n=102, examined twice) and healthy age-ma...

Objective: QT interval prolongation of unknown aetiology is common in Turner syndrome (TS). This study set out to explore the presence of known pathogenic long QT (LQT) mutations in TS and to examine the corrected QT interval (QTc) over time and relate the findings to the TS phenotype.Methods: Adult females with TS (n=102) were examined thrice with a mean follow-up of 4.7±0.5 years, and 68 age-matched healthy controls were examined once. QT...

Objective: Early puberty is associated with increased risk of subsequent cardiovascular disease. Low sex hormone-binding globulin (SHBG) levels are a feature of early puberty as well as conditions associated with increased cardiovascular risk. The aim of the present study was to evaluate SHBG as predictor of glucose metabolism and metabolic risk during puberty.Research design and methods: Cross-sectional study on 132 healthy Caucasian children and adoles...

Objective: The short-term cardiovascular effects of continuous ghrelin infusion in healthy humans remain to be studied.Methods: Fifteen healthy, young and normal-weight men volunteered to participate in a randomized double-blind, placebo-controlled cross-over study. The local ethics committee approved the study. We used a constant infusion of human ghrelin at a rate of 5 pmol/kg body weight per minute for 180 minutes and measured peak left ventricular my...
