Air Pollution, Exercise, and Cardiovascular Risk

It’s no surprise that poor air quality causes health problems.

I occasionally used to run in downtown Baltimore; the revitalized Inner Harbor is a vibrant place to run. Yet each time I finished, a thin but noticeable coat of dirt covered my body. I never got so dirty running my usual suburban routes and even on my trail runs.

What a Catch-22: sit around, don’t exercise and have a heart attack vs. run/exercise outside and have a heart attack.

NEJM — Air Pollution, Exercise, and Cardiovascular Risk
There is mounting evidence that exposure to higher levels of air pollution is associated with adverse cardiovascular consequences. A recent scientific statement from the American Heart Association concluded that transient changes in air pollution are associated with a short-term increased risk of cardiovascular disease and death. There is also convincing evidence for an association between air pollution and myocardial ischemia and infarction, ventricular arrhythmia, heart failure exacerbation, and stroke.
