Cardiovascular Effects of Secondhand Smoke: Nearly as Large as Smoking

  title={Cardiovascular Effects of Secondhand Smoke: Nearly as Large as Smoking},
  author={Joaquin Barnoya and Stanton A. Glantz},
Background—Secondhand smoke increases the risk of coronary heart disease by ≈30%. This effect is larger than one would expect on the basis of the risks associated with active smoking and the relative doses of tobacco smoke delivered to smokers and nonsmokers. Methods and Results—We conducted a literature review of the research describing the mechanistic effects of secondhand smoke on the cardiovascular system, emphasizing research published since 1995, and compared the effects of secondhand…

Smoking, Secondhand Smoke, and Cardiovascular Disease

A comprehensive tobacco control program, that includes taxation, smoke-free environments, and exposing the tobacco industry, has been shown to be effective in decreasing smoking prevalence and cardiovascular disease mortality.

Cardiovascular Effects of Second-hand Smoke Help Explain the Benefits of Smoke-free Legislation on Heart Disease Burden

Cardiovascular nurses should advise their patients and relatives to avoid SHS exposure and demand smoke-free workplaces and homes.

Secondhand smoke as an acute threat for the cardiovascular system: a change in paradigm.

Data strongly suggest that passive smoking is capable of precipitating acute manifestations of CVD (atherothrombosis) and may also have a negative impact on the outcome of patients who suffer acute coronary syndromes.

Protecting Europeans from secondhand smoke: time to act.

The authors conclude, ‘clinicians need to inform their patients about the risks associated with passive smoking and strongly support the enforcement of smoking bans in all public places’ and this advice comes at an important time for cardiologists and others concerned with heart health in Europe, where the movement for smoke-free air has finally arrived.

Exacerbation of Viral Myocarditis by Tobacco Smoke: The Catecholamine Hypothesis

Making all workplaces smoke free as been accomplished for the commercial aircraft industry would in one year prevent about 1500 myocardial infarctions and 350 strokes, and result in nearly 49 million dollars in savings in direct medical costs.

Association between secondhand smoke exposure and hypertension: nearly as large as smoking.

Current evidence regarding the association between secondhand smoke exposure and hypertension as well as exploration of the links between SHSE and hypertensive end-organ damage are focused on.

This paper reexamines the empirical relation between self-reported low levels of active smoking and risk of coronary heart disease (CHD) in public-domain data from the National Health and Nutrition Examination Survey (NHANES).

Secondhand smoke exposure and cardiovascular disease

It has become clear that short-term, intense exposure to SHS may function as an important trigger of clinical manifestations of CHD via multiple mechanisms such as endothelial dysfunction, platelet activation, oxidative stress, inflammation, and alterations of the autonomic nervous system.

Exposure to Secondhand Smoke and Biomarkers of Cardiovascular Disease Risk in Never-Smoking Adults

Background— Exposure to secondhand smoke has been associated with a disproportionately high risk of coronary heart disease, thought to be mediated through inflammation, platelet aggregation, and/or

Effects of Tobacco Smoking on Cardiovascular Disease.

Physicians should be particularly alert to the development and progression of heart failure, atrial fibrillation, and venous thromboembolism, as well as ischemic CVD among tobacco smokers.



Secondhand smoke: the evidence of danger keeps growing.

Passive smoking and cardiovascular risk.

Evidence indicates that nonsmokers are more sensitive to smoke, including cardiovascular effects, and that sidestream smoke contains higher concentrations of gas constituents, including carbon monoxide, which makes passive smoking a relevant risk factor for heart disease morbidity and mortality.

How acute and reversible are the cardiovascular risks of secondhand smoke?

The results of the observational study in Helena, MT are provocative: hospital admissions for acute myocardial infarction declined by about 40% during the six months in which a comprehensive local ordinance on clean air was in effect, and rebounded after the ordinance was suspended.

Association between passive cigarette smoking and the risk of developing acute coronary syndromes: the CARDIO2000 study

The hypothesis that passive smoking increases the risk of developing acute coronary syndromes among nonsmokers is supported and the public health consequences of passive smoking with regard to coronary heart disease may be important.

Passive smoking and heart disease. Mechanisms and risk.

OBJECTIVE--Recent clinical, laboratory, and epidemiological evidence that passive smoking causes heart disease was reviewed, with particular emphasis on understanding the underlying physiological and

Effect of exposure to secondhand smoke on markers of inflammation: the ATTICA study.

Passive smoking and the risk of heart disease.

The public health burden due to ETS exposure is likely to be much greater for heart disease than for lung cancer, which has been the focus of most debate to date.

Acute effects of passive smoking on the coronary circulation in healthy young adults.

Passive smoking substantially reduced coronary flow velocity reserve in healthy nonsmokers, providing direct evidence that passive smoking may cause endothelial dysfunction of the coronary circulation in nonsmoker.

Passive smoking and heart disease. Epidemiology, physiology, and biochemistry.

The combination of epidemiological studies with demonstration of physiological changes with exposure to ETS, together with biochemical evidence that elements of ETS have significant adverse effects on the cardiovascular system, leads to the conclusion that ETS causes heart disease.
