Secondhand Smoke Exposure is a Major Cause of Heart Attacks
- Even brief exposure to secondhand smoke can trigger a heart attack.1
- In just five minutes of exposure, secondhand smoke makes it harder for the heart to pump blood.2
- In 20-30 minutes, fat and blood clots build up in the arteries, increasing the chance of heart attacks and stroke.2
- After 2 hours of secondhand smoke exposure, the heart rate speeds up and leads to abnormal heart rhythms (which can lead to death).2
- A heart attack may be more severe than it would have been in the absence of exposure to secondhand smoke.3
Secondhand Smoke Exposure is a Major Cause of Heart Disease and Stroke
- Fine particle air pollution, carbon monoxide, and nicotine in secondhand smoke are linked to heart disease.1
- Exposure to secondhand smoke has immediate adverse effects on the heart and blood vessels and it causes heart disease and increases the risk of stroke.2
- People who are exposed to secondhand smoke increase their risk of heart disease by 25-30%.1
- Secondhand smoke and its toxic chemicals damage the cardiovascular system by causing inflammation and blood clots. This evidence suggests that a causal relationship between secondhand smoke and stroke is biologically plausible.1,3
- Adults who breathe secondhand smoke every day have higher levels of the “bad” cholesterol that can clog the arteries of the heart.3
Smoke-free Laws and Heart Attacks
- After strong smoke-free laws go into effect, communities experience a 15% drop in heart attacks during the first year, with continued decline of 36% in 3 years.4
- Smoke-free laws create healthy places for workers and patrons to breathe clean air, and they reduce health care costs. Smoke-free laws are a known public health solution.1
