The aim of this study was to analyze the structural cardiac remodeling of rats exposed to the herbicide glyphosate chronically. Twenty male adult Wistar rats (300-450 g) were used, divided into a control group (CG, n=10) and group of rats fed diet contaminated by glyphosate (OG), n =10) for 180 days. After the experimental period, the rats were euthanized and to evaluate structural cardiac remodeling the heart was dissected in the left ventricle (LV), atriums (ATs) and right ventricle (RV) and heavy. There was an increase in the atrium (CG= 0,084±0,22mg e OG 0,105±0,21mg, p=0,048), right ventricles (CG= 0,219±0,04mg e OG= 0,276±0,03mg, p=0,036) and left ventricles (CG= 0,950±0,05mg e OG= 1,030±0,09mg, p=0,040) in the group exposed to glyphosate. Glyphosate promoted an increase in the cardiac chambers of rats that ingested contaminated feed.
