Passive smoking increases the risk of heart disease

26.06.2002


A new study published in BMC Public Health shows that breathing in second-hand smoke significantly increases the risk of developing heart problems in non-smokers. These findings have serious consequences for public health giving weight to calls for smoking to be banned in public places.



In 1995 cardiovascular diseases accounted for nearly 15 million deaths, approximately 30% of deaths worldwide. Smokers are becoming increasingly aware of the links between smoking and heart disease as warnings such as "smoking causes heart disease" are emblazoned across cigarette packaging across the world. The effects of second hand smoke or passive smoking is less clear because it is difficult to measure the exposure of non-smokers to cigarette smoke. Researchers at the University of Athens in Greece have carried out an extensive survey of approximately 2000 non-smoking patients. The patients were volunteers from two different groups, the first contained patients who had attended hospital suffering from a heart attack or acute angina that was not a result of a pre-existing condition. The second control group consisted of patients being treated as outpatients for routine examinations or minor surgical procedures who had no history of cardiovascular problems.

Both groups completed a questionnaire, which asked a variety of questions to identify factors that may put them at risk of developing heart problems. These factors included age, hypertension, high cholesterol, diabetes, a family history of heart disease, physical inactivity, obesity, poor education, depression and low income.


In addition, their exposure to second hand cigarette smoke was gauged by asking two questions: "Are you currently exposed to cigarette smoke to more than 30mins/day?" and "As an adult how many years have you been exposed to second hand smoke?"

The researchers analysed the odds of developing heart disease for non-smokers who were exposed to cigarette smoke whilst excluding the effects of other factors.

The results showed that even people who were exposed to cigarette smoke less than 3 times a week (for more than 30 minutes on each occasion) had a 26% increased risk of developing acute heart disorders. These results led the researchers to conclude that "The only safe way to protect non-smokers from exposure to cigarette smoke is to eliminate this health hazard from public places through legislation"

Indeed they go further to suggest that "the consistency of these findings ... increases the belief that the observed association (between passive smoking and heart disease) may represent cause and effect."

Im Focus: How do scars form? Fascia function as a repository of mobile scar tissue

Abnormal scarring is a serious threat resulting in non-healing chronic wounds or fibrosis. Scars form when fibroblasts, a type of cell of connective tissue, reach wounded skin and deposit plugs of extracellular matrix. Until today, the question about the exact anatomical origin of these fibroblasts has not been answered. In order to find potential ways of influencing the scarring process, the team of Dr. Yuval Rinkevich, Group Leader for Regenerative Biology at the Institute of Lung Biology and Disease at Helmholtz Zentrum München, aimed to finally find an answer. As it was already known that all scars derive from a fibroblast lineage expressing the Engrailed-1 gene - a lineage not only present in skin, but also in fascia - the researchers intentionally tried to understand whether or not fascia might be the origin of fibroblasts.
