Overwhelming medical and scientific research concludes that cigarette smoking causes lung cancer, heart disease, emphysema and other serious diseases in smokers. Smokers are far more likely to develop serious diseases, like lung cancer, than nonsmokers. There is no "safe" cigarette.
Smokers who have heart failure can automatically eliminate a major source of stress on their heart by quitting. Each puff of nicotine temporarily increases heart rate and blood pressure, even as less oxygen-rich blood circulates through the body. Smoking also leads to clumping or stickiness in the blood vessels feeding the heart. People who quit smoking are more likely to have their heart failure symptoms improve.
