| Outline of Final Research Achievements |
The frequency of sarcopenia was 27.8% for men and 41.8% for females in patients with cardiovascular disease admitted to our Heart Center. The prevalence of sarcopenia was high in patients with heart failure and CKD. Furthermore, we examined blood biomarkers related to muscle atrophy and sarcopenia, and revealed that adiponectin, GDF-15, and acylcarnitine are closely related. In the future, we will extract and quantify microRNAs in exosomes from preserved blood and investigate the further biomarkers. We also examined the effects of new rehabilitation methods, low-intensity electrical stimulation under moderate blood flow restriction known as KAATSU training, and waon therapy using thermal stimulation, as a countermeasure. Particularly, in this study, the fact that basic experiments could prove muscle hypertrophic effect and its underlying molecular mechanisms on skeletal muscles may have provided important information as a basis for future clinical research.
