Fact Sheet
Secondhand Smoke Causes Heart Disease
(May 2007)
- Secondhand smoke exposure has immediate adverse effects on the cardiovascular
system and causes coronary heart disease.1
- Secondhand smoke is estimated to cause from 22,700 to 69,600
premature deaths from heart disease each year in the United States
among nonsmokers.2
- Nonsmokers who are exposed to secondhand smoke at home or at
work increase their risk of developing heart disease by 25–30%.1
- Breathing secondhand smoke can have immediate adverse effects on
your blood and blood vessels, potentially increasing the risk of a heart
attack.1
- Breathing secondhand smoke interferes with the normal functioning
of the heart, blood, and vascular systems in ways that increase
the risk of a heart attack.
- For some of these negative effects, the immediate impact of
even short exposures to secondhand smoke appears to be almost as
large as that observed in active smokers.
- Even a short time in a smoky room can cause your blood platelets
to become stickier.
- Even brief secondhand smoke exposure can damage the lining of
blood vessels.
- Short exposures to secondhand smoke can decrease coronary flow
velocity reserves to levels observed in smokers and reduce heart
rate variability.
- Adults who breathe 5 hours of secondhand smoke daily have higher
levels of the “bad” cholesterol that can clog the arteries of the
heart.
- Coronary heart disease is the single leading cause of death in the United States. In 2003, an estimated 1.2 million Americans had a coronary attack.3 Many Americans have heart disease without knowing it.4
- Persons who already have heart disease are at especially high risk
of suffering adverse effects from breathing secondhand smoke, and should
take special precautions to avoid even brief exposures.1
- Secondhand smoke exposure can also make a heart attack more
severe than it would have been in the absence of exposure.1
