Tea catechins have many biological functions; these effects are induced by the suppression of several inflammatory factors. However, the effects of catechins on ventricular remodeling after myocardial ischemia have not been well investigated. To test the hypothesis that catechins can attenuate chronic ventricular remodeling after myocardial ischemia, we performed oral administration of catechins into rat myocardial ischemia models. We analyzed the mechanisms using physiological, pathological and molecular examinations. Although severe myocardial fibrosis with enhancement of inflammatory factors were observed in the non-treated ischemia group on day 28, catechins attenuated these changes with suppressed NF-κB and matrix metalloproteinases without systemic adverse effects. Catechins are potent for the suppression of chronic ventricular remodeling after myocardial ischemia because they are critically involved in the suppression of several inflammatory genes.
