Jaboticaba () Attenuates Ventricular Remodeling after Myocardial Infarction in Rats.

The cardiac remodeling after myocardial infarction is characterized by inflammation and oxidative stress. Thus, this study aimed to test the hypothesis that jaboticaba, due to its anti-inflammatory and antioxidants properties, attenuates cardiac remodeling after myocardial infarction. Wistar rats were submitted to myocardial infarction due to coronary artery occlusion, and divided into four experimental groups: C, sham control animals; I, animals submitted to myocardial infarction, received a standard diet; IJ2, animals submitted to myocardial infarction, received a standard diet plus 2% jaboticaba; and IJ4, animals submitted to myocardial infarction, received a standard diet plus 4% jaboticaba.

Impact of Modality and Intensity of Early Exercise Training on Ventricular Remodeling after Myocardial Infarction.

The objective of this study was to analyze the impact of different modalities and intensities of exercise training on cardiac remodeling started early after experimental myocardial infarction (MI). Male Wistar rats, weighing 200-250 g, were subjected to experimental MI. After 5 days, the animals were allocated into three experimental groups and observed for three months: S (sedentary control animals), C (animals subjected to continuous low-intensity training), and HIT (animals subjected to high-intensity interval training).
