Hidden fat, hidden risk: study probes heart danger in slim women
NCT ID NCT06818500
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether women with a normal BMI but higher body fat have hidden blood vessel problems. Researchers will measure how their blood vessels react after a fatty meal and a stressful task. The goal is to understand if body composition matters more than weight for heart disease risk.
