Second hand smoke exposure raises heart disease risk by 90%

Second hand smoke exposure raises heart disease risk by 90%

Most people understand that smoking is the #1 cause of death worldwide but most people also do not understand that being around smokers – even if you do not smoke – is just as bad for you and your children.

“This research provides additional evidence that secondhand smoke is harmful and may be even more dangerous than we previously thought”
Dr. Harvey S. Hecht.

From the Heart Disease and Stroke 2013 Statistical Update – Smoking and Tobacco Use, Harvey S. Hecht, MD, of Mount Sinai Medical Center in New York City, and colleagues, have just reported online in JACC: Cardiovascular Imaging that:

  • Those with the highest amount of cigarette smoke exposure were 90% more likely to have coronary plaque than the general public
  • There was a very significant and independent dose-response relationship of secondhand tobacco smoke exposure to coronary artery calcification in non-smokers
  • The odds associated with developing coronary disease from secondhand smoke were greater than diabetes, high cholesterol, high blood pressure or renal disease
  • The overall prevalence of coronary artery plaque in those exposed to secondhand smoke was 24% - rising to 26% in those with the highest exposure
  • This study proves a clear dose-response relationship between secondhand smoke exposure and the earliest detectable signs of heart disease

Study by Hecht HS, et al “Secondhand tobacco smoke in never smokers is a significant risk factor for coronary artery calcification” J Am Coll Cardiol Cardiovascular Imaging 2013.  Data from 3,098 asymptomatic people who had never smoked in the Flight Attendant Medical Research Institute International Early Lung Cancer Action Program CT (a lung screening program), compiled in the Heart Disease and Stroke 2013 Statistical Update – Smoking and Tobacco Use ‘Smokeless Tobacco and CVD’ as presented by Hecht to the American College of Cardiology meeting, in San Francisco, March 2013.  As reported by MedPage Today on March 08, 2013.
