Background: The QT interval, corrected for sex and heart rate (QTc), measures the duration of the cardiac action potential and can indicate the risk of arrhythmias. The QT interval is typically longer in women compared to men; a phenomenon often attributed to estrogen's effects. However, conflicting data exist regarding the effects of gonadotropin-releasing hormone agonist (GnRHa) and gender-affirming hormonal treatment (GAHT) on QT intervals and dispersi...

Introduction: Turner syndrome (TS) is a genetic condition which is reported to be associated with electrocardiogram (ECG) abnormalities, of which the rate-corrected QT interval (QTc) is the most common indicated deviation. Our objectives were to gain more insight in the prevalence of QTc-prolongation using both Bazett's and Hodge's correction formulas in patients with TS of all ages and to investigate whether QTc prolongation is more prevalent in patie...

Background: Congenital adrenal hyperplasia (CAH) is characterized by cortisol deficiency and hyperandrogenism. Both hyperandrogenism and treatment with supraphysiological doses of glucocorticoids may cause unfavorable changes in the cardiovascular risk profile of CAH patients. Data on the cardiac function in CAH patients is scarce.Objective and hypotheses: To evaluate the cardiac function in pediatric CAH patients.Method: The cardi...

Background: Patients with congenital adrenal hyperplasia (CAH) are at risk of developing an unfavorable cardiovascular risk (CVR) profile. Data on the CVR profile in pediatric CAH patients are scarce.Objective and hypotheses: To evaluate the CVR profile of pediatric CAH patients.Method: A cross-sectional study in CAH patients (8–16 years) was performed (n=27). Blood was taken to evaluate several circulating CVR marker...
