Abstract :

Background: Diet-induced obesity is one of the leading causes of cardio vascular morbidity and mortality that correlates with the duration and intensity of adiposity. This study tested the hypothesis that the increased time of exposure to obesity intensifies the cardiac dysfunction. In addition, it is also examined whether the functional impairment is due to increased levels of myocardial collagen. Methods: Thirty-day-old male Wister rats were distributed in control (C) and obese (Ob) groups. The C was fed a standard diet and Ob was alternately submitted to four palatable high-fat diets for 15, 30 and 45 weeks. The obesity was determined by adiposity index. The cardiac remodeling process was assessed by structural and functional analysis. Results: Adiposity index was higher in Ob than C overtime. Obesity promoted several co morbidities after 15, 30 and 45weeks. LV mass and inter ventricular septum and posterior wall thickness in dias to le after 15, 30 and 45 weeks were increased in Ob. However, obesity has led to an increase in LV relative wall thickness in the 30th and 45th weeks. Obesity did not promote changes in LV interstitial collagen in all periods. Obesity improved the systolic function after 30 weeks and myocardial dys- function after 15 weeks, however, the duration of obesity did not intensify the cardiac dys-function in vitro. Conclusions: Long time exposure to obesity does not intensify the cardiac dys-function and does not promote alterations on myocardial collagen
