The changes in right ventricular structure and function connected to traffic air pollution

According to a new study, getting exposed to the high point of air pollution from traffic is connected to the changes in the right ventricle of the heart as it contributes to the identified relation between the heart disease and exposure to air pollution. It is said by a leading author Peter Leary, MD, MS, of the University of Washington Medical Center in Seattle that, “Although the link between traffic related air pollution and left ventricular hypertrophy, heart failure and cardiovascular death is established, the effects of traffic related air pollution on the right ventricle have not been well studied.” Later the findings were published online in the American Thoracic society’s American Journal of Respiratory and Critical Care Medicine. In the study, nearly 3,896 participants involved who were free from clinical cardiovascular diseases and those who underwent cardiac magnetic resonance imaging. Well, the authors found that the more exposure to nitrogen dioxide was related with an approximate 1.0g rise in the right ventricular mass and 4.1ml rise in the right ventricular end diastolic size.
