4. DiscussionThe main finding of this study is that exercise training on peripheral and respiratory muscles in CAD patients with MetS improves respiratory function resulting in clinical improvement, as evidenced by dyspnea scores and exercise stress test results. This finding was comparable among all three study groups, although there were some differences in the PMT findings. The improvement was more pronounced in the NMES + PMT group. With few exceptions, inflammation markers (CRP and ESR) were also positively influenced by exercise. This study is the first to apply PMT and different IMT methods and investigate their effects in CAD patients with MetS.
