Blood Flow Reserve: Effects After Training With Heavy Inspiratory Exercises
Coronary Artery DiseaseThe goal of this single-site, parallel-group, double-blind, sham-controlled randomized control trial is to examine the effect of high-intensity inspiratory muscle strength training (IMST) on coronary blood flow assessed using positron emission tomography coronary perfusion imaging in patients with coronary artery disease (CAD).
The main question it aims to answer are:
• if high-intensity IMST will improve coronary blood flow in patients with CAD, which could be assessed using positron emission tomography coronary perfusion imaging.
Participants will be asked to complete the 8-week high-intensity or low-intensity IMST. Researchers will compare high and low-intensity IMST groups to see if coronary blood flow increases after IMST.
