Research Abstract |
This study was to explore mechanisms related to improvement in cardiac function of advanced heart failure with a specific focus on fibrosis in the cardiac tissue. Firstly, cardiac tissue was surgically sampled from the patients having advanced heart failure at the time of left ventricular device implantation and at the time of cardiac transplantation. As a result, mechanical support by the device improved cardiac function but not reduced cardiac fibrosis. In contrast, regenerative treatment for a rat advanced heart failure model induced dynamic up-regulation and down-regulation of the factors related to synthesis and degradation of the fibrosis, consequently reducing cardiac fibrosis, indicating the importance of cardiac fibrosis in advanced heart failure.
