Smoking causes Cardiovascular dieseases

CARDIOVASCULAR DISEASE

The most common cause of death in the United States is coronary heart disease, and over the past 20 years many studies have shown an association between this disease and smoking. In coronary heart disease, the coronary arteries which nourish the heart muscle itself become narrowed by deposits. When one of the coronary arteries becomes obstructed, usually by a clot that forms in the narrowed, roughened vessel, a heart attack results.


Certainly many factors may enter into the development of coronary artery disease. Sedentary living is one. Diet, particularly diet heavily laden with fats, is another. Excess weight may be involved. High blood pressure is an important factor. But cigarette smoking has been found to be associated with the disease to the point that, as far back as 1965.
