Impact of Supraphysiological Estradiol on ECG in IVF Patients

NCT07007416 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 62

Summary

This prospective observational study aimed to evaluate the effects of supraphysiological estradiol (E2) levels, induced by gonadotropin therapy during IVF, on cardiac electrophysiological parameters. Sixty-two women aged 18-40 undergoing IVF treatment at Konya City Hospital between December 2024 and January 2025 were included.

ECG recordings were performed twice: once before gonadotropin stimulation and again on the day of hCG administration, when peak E2 levels were expected. Routine blood tests and hormone levels were also evaluated. Patients with obesity, cardiovascular disease, chronic illness, or medication use were excluded.

After treatment, significant increases were observed in PR interval, J-Tpeak, QTc, and Tp-e values. E2 changes showed a moderate negative correlation with QTc and a low positive correlation with J-Tpeak.

The results suggest that elevated E2 levels during IVF may affect cardiac electrophysiology, highlighting the need for careful monitoring in women with cardiac risk factors.
