Aircraft Noise can Damage the Heart

The lead and senior authors, Michael Molitor and Philip Wenzel commented: “We learned from our studies that aircraft noise exposure before MI substantially amplifies subsequent cardiovascular inflammation and aggravates ischemic heart failure, facilitated by pro-inflammatory vascular conditioning. Our translational results show that humans that had noise exposure in the past will have a worse outcome if they have an acute MI later in life.”

Transportation Noise may be a Risk Factor for Heart Disease

This is the first time that a translational study has been performed to investigate the effects of aircraft noise on acute myocardial infarction. In experimental animals and humans, aircraft noise markedly exaggerated the consequences of ischemia (left ventricular function, inflammation, and oxidative stress) in response to an acute myocardial infarction. There is no doubt anymore that transportation noise must be considered an important cardiovascular risk factor, comparable to hypercholesterolemia, hypertension, smoking, and diabetes mellitus.

The results of the study suggest, that measures to reduce environmental noise exposure will be helpful in improving the clinical outcome of subjects with MI.
