| Outline of Final Research Achievements |
Exercise tolerance, not left ventricular ejection fraction, was important prognostic indicator for patients with chronic heart failure. Cardiac rehabilitation can prevent major cardiac adverse events. However, this mechanism is still unknown. Skeletal muscle has recently been identified as an organ that produces and releases cytokines, named “myokines.” We investigated whether serum brain derived neurotropic factor (BDNF) level or irisin, which is one of myokines, level at discharge could predict the prognosis in patients with heart failure (HF). This study consisted of patients who were hospitalized for worsening heart failure and had cardiac rehabilitation at least 1 week. We measured serum BNDF, and irisin. One-year follow-up was completed in all of the patients. Kaplan-Meier analysis demonstrated that the event free rate was decreased in the low BDNF or irisin group. Myokines level at discharge may be a useful biomarker for the prognosis in patients with HF.
