Five million deaths are attributable to smoking each year worldwide, including 35% by cardiovascular disease is two times more than by lung cancer. Active or passive smoking, all are affected by this danger.
This year marks the gradual implementation of the law banning smoking in public places. On this occasion, the French Federation of Cardiology (FFC) and the French society of Cardiology (SFC) are committed in 2007 for a “heart without tobacco”.
No small risk tobacco
Smoking is the second most important risk of myocardial infarction, closely behind excess cholesterol. It is a full cardiovascular risk, especially for young since issue 80% of victims of myocardial infarction under 45 years old are smokers. Most people smoke, more it is exposed to this risk. Thus, there is no “small risk” tobacco since the risk increased 63% from 1 to 9 cigarettes per day.
The heart is the first victim of passive smoking, since nearly 60% deaths that are attributable to him (i.e. 3 500 people) would be due to a myocardial infarction or cerebrovascular accident.
The harmful effects of passive smoking
The risk of myocardial infarction is also passive smokers. For an exhibition from 1 to 7 hours per week, the risk increases of 24% and 62% for an exhibition of more than 22 hours per week. Finally, in France, 5,800 deaths attributed to passive smoking, about 60% are cardiovascular deaths by myocardial infarction or stroke.
“So, smoking can no longer be considered as a matter of individual choice, that is a danger to public health” judge Pr Daniel Thomas of the Institute of cardiology at Hôpital Pitié-Salpêtrière (Paris).
The benefits of stopping
Quitting smoking is the best prevention against cardiovascular disease. The new ban on smoking in public places from February 2007 should have a direct impact on the reduction of cardiovascular mortality. Following this same measure in Italy, a study found a reduction of 11% of admissions for myocardial infarction in Piedmont Hospital. Something closer to what had been observed in the United States in two cities of Montana and Colorado: the number of myocardial infarction declined significantly (respectively by 40% and 27%) after the ban on smoking in public places. “Extrapolating the results of these studies to the France we can hope to avoid 5-7,000 heart attack per year (out of a total of 120 000)” considers Pr Daniel Thomas.
After weaning, the risk of thrombosis in the smoking is reversible pretty quickly, even for heavy smokers, and especially after a cardiovascular accident. Of course, the withdrawal benefit is larger as one stops. for example, a smoker who stops between 35 and 44 years old found a life expectancy almost equal to that of non-smokers.
The figures are also talking in secondary prevention, i.e. after a cardiovascular accident: quit smoking after a heart attack decreased from 36 to 50 the risk of a new accident within 5 years.
Pr Daniel Thomas points out that “no surgical and even drug preventive measures provides also fast and important benefit without risk of deleterious effect.” Yet in France, 50% of the victims of a coronary accident resumed smoking 18 months later”.
