Abstract

According to data from the Ministry of Health, cardiovascular diseases are the most common cause of death in all regions of Brazil, representing 28.6% of the 1,170,498 deaths in 2011. Among them we highlight the coronary arterial diseases and Heart Failure (HF). Among the factors related to the development of HF, the Cardiac Remodeling (CR) process is one of the most important. Recently, Exposure to Cigarette Smoke (ECS) has been investigated in experimental studies and clinical trials, as one of the causes of RC. It is believed that the increased inflammation and oxidative stress are involved in this process. In order to attenuate the CR process induced by ECS, various substances are being studied. Among these substances with anti-inflammatory and antioxidant potential, fruit as cajá is one of the most important. The cajá (Spondias Mombin-SM), is an ovoid fruit characterized by presenting juice sweet/sour, found mainly in the States of north and northeast of Brazil. It is believed that its effects are secondary to phenolics, flavonoids and carotenoids present in fruit. Study that evaluated the administration of cajá before myocardial aggression by isoproterenol observed increased activity of superoxide dismutase and catalase and reduced concentrations of GSH and malondialdehyde. However, the effects of cajá on cardiac remodeling process induced by the ECS has not yet been studied. Thus, we believe that, by their antioxidant and anti-inflammatory effects, SM supplementation can attenuate the CR process induced by ECS. Therefore, the objective of this study is to evaluate the influence of cajá supplementation on cardiac remodeling process induced by ECS in rats. (AU)
