Secondhand Smoke May Be More Dangerous Than Previously Thought
Secondhand smoke exposure found to be an equivalent or stronger risk factor than high cholesterol, hypertension, and diabetes
New research presented last week at the American College of Cardiology Meeting in San Francisco found that 26% of never smokers exposed to secondhand smoke as either an adult or child had signs of coronary artery calcification compared to 18.6% for the general population. When the researchers took other risk factors into consideration, the association still remained with those exposed to low, moderate, or high amounts of secondhand smoke being 50, 60, and 90%, respectively, more likely to have evidence of calcification compared to those with minimal exposure.
The researchers noted that the findings add to the evidence of the need to protect people from secondhand smoke. They also suggested that a discussion of secondhand smoke exposure be included in routine medical exams.
