Outline of Final Research Achievements

Chronic mechanical load to myocardium due to hypertension or cardiac valve diseases leads to the heart failure. Any substances that mediate such response look “evil”, though, they also have physiological roles. Therefore, it is important to understand their physiological and beneficial roles, otherwise any attempts aimed to eliminate such “evil” substances would have side effects by eliminating their physiologically required roles. In the present study, roles of reactive oxygen species (ROS), which has been regarded as an “evil” substance, in physiological and pathological response to myocardial mechanical load was studied, and its role in linking cardiac physiology and pathophysiology was demonstrated. The present results may be useful for the development in safe methods for the treatment and/or prevention of heart failure without side effects.
