First seen Mar 31, 2026 · Last updated May 14, 2026 · Updated 5 times

Summary

This study looked at whether the hormones progesterone (in women) and testosterone (in men) can reduce dangerous changes in heart rhythm caused by certain medications. 73 healthy older adults (postmenopausal women and men 65+) took either the hormone or a placebo, then received a small dose of a heart-rhythm-altering drug. Researchers measured how the heart's electrical activity changed to see if the hormones offered protection.
