Previous studies have shown that exposure to particulate matter (PM) increased variety of health problems, particularly cardiovascular diseases leading to premature mortality. The cardiac effects of particulate matter containing PMinclude increased infarct size, decreased heart function, and increased arrhythmias in experimental ischemia-reperfusion models in rats. The aim of this study was to evaluate the effects of particles with an aerodynamic diameter smaller than 10μm (PM) on isolated-rat heart and also to determine the efficacy of gallic acid (GA) as a preventive agent in oxidative damage. The healthy rats were divided into 8 equal groups which served as, control, GA, PM(0.5, 2.5, and 5 mg/kg), and PM+GA groups. PMadministered into the lungs via the trachea in two stages with 48-h interval. After all experiments, the electrocardiogram was recorded. Then, the hemodynamic parameters and ventricular arrhythmias in rat isolated-hearts were assessed using Langendorff apparatus and according to the Lambeth conventions. In addition, the inflammation and oxidative stress factors in cardiac tissues were evaluated in all groups. The obtained results showed that the exposure to PM caused to decrease in cardiac hemodynamic and electrocardiogram parameters. Also, in PMrat groups, the IL-6, TNF-α, and oxidative stress parameters were increased. Gallic acid preserved the value of cardiac parameters and inflammation in rat hearts. In summary, we added a novel therapeutic effect of gallic acid for cardiac dysfunction induced by particulate matter. These findings could be related to antioxidant and antiinflammation properties and the obtained results suggest that natural antioxidant like gallic acid could be a therapeutic agent in prevention and management of health issues in the polluted areas of the world.
