Official title: The Cardiovascular Impact of Hot Flushes
Run by University of Minnesota · NCT05251324 · Data updated 2026-11-12
This study tests how hot flushes affect heart and breathing responses in postmenopausal women to see if symptoms and body fat impact these effects.

What this trial studies
This observational study aims to investigate the physiological responses during hot flushes in postmenopausal women. It will utilize a temperature-controlled heating pad to induce hot flushes and assess cardiovascular and respiratory responses in symptomatic versus asymptomatic women. The study will also explore the influence of body fat percentage on the severity and frequency of hot flushes. The findings could provide insights into the cardiovascular risks associated with vasomotor symptoms in postmenopausal women.
Why it matters
Potential benefit: If successful, this study could enhance understanding of the cardiovascular risks linked to hot flushes, potentially leading to better management strategies for postmenopausal women.
How similar studies have gone: While studies on hot flushes and cardiovascular responses exist, this specific approach using a controlled induction method is relatively novel.
