Patients with coronary artery disease (CAD) have a lower capillary-to-fiber ratio (C/Fi) and capillary-to-fiber perimeter exchange (CFPE) index in Type II fibers compared to healthy controls.
Understanding these differences can inform targeted rehabilitation strategies for CAD patients.
StrongSupportsmedium confidence
We found that CAD had a lower capillary-to-fiber ratio (C/Fi, 35% ± 25%, P = 0.06) and capillary-to-fiber perimeter exchange (CFPE) index (23% ± 29%, P = 0.034) in Type II fibers compared with healthy controls.
Why this rating
The study involves a randomized controlled trial design.
