Air pollution and strokes

This isn't the first blog posting about the potential link between air pollution and strokes, but  ran across yet another article about research on air pollution - including indoor smoking - and how air pollution, heart disease and stroke:

Pollution can come from traffic, factories, power generation, wildfires or even cooking with a wood stove. One of the most common indoor sources is smoking — a danger to the person lighting up and to those nearby.
 “There are a wide variety of things in the air. Some are natural, some are manmade,” said Russell Luepker, M.D., a cardiologist and the Mayo professor in the School of Health at the University of Minnesota. “We are all exposed, to a certain degree.”
Acute short-term effects of air pollution tend to strike people who are elderly or already struggling with heart disease, said Dr. Luepker, who is also an epidemiologist.
For instance, someone with atherosclerosis, or build up of fatty deposits on the inner lining of the arteries, experiences immediate trouble when pollutants play a role in causing plaque in a blood vessel to rupture, triggering a heart attack.
“This kind of pushes them over the cliff,” Dr. Luepker said.
