[Tobacco smoking among hospitalised patients with coronary arterial disease].

The impact of tobacco smoking on the development of cardio-vascular diseases, including coronary arterial disease (CAD) is very well known by now. More than 1/3 of the Polish adult population are affected which roughly corresponds with WHO accepted percentage of smokers world-wide (over 30%, over 15 years of age). Smokers with cardio-vascular problems are, naturally, even more dramatically affected.
