[Lifestyle and cardiovascular risk].

This paper describes the relation between lifestyle and cardiovascular risk globally and for each lifestyle risk factor. In 3 large studies (Interheart, HALE project and the Nurses' health study), four risk factors have been identified: smoking, diet, low level of exercise and low or no alcohol consumption. Prevention of atherosclerotic diseases can be obtained by smoking cessation, diet modifications aimed at lowering body weight and having a Mediterranean style diet, continuing lifelong physical activity such as walking more than two hours a week. Alcohol consumption, although related to lower risk, cannot be prescribed as a preventive action.
