[Competitive sports and leisure-time physical activity in patients with coronary heart disease]

During recent years, the central role of exercise in the prevention of cardiovascular disease has gradually been demonstrated, and in 2003 the consensus document of the Council on Clinical Cardiology and Council on Nutrition, Physical Activity and Metabolism on the role of physical exercise in the prevention and treatment of coronary artery disease defined sedentary lifestyle as a modifiable independent cardiovascular risk factor, responsible for 12% of total mortality in the United States and for a 1.9-fold increase in the risk of ischemic heart disease. The reduction in cardiovascular mortality and cardiac ischemic events in subjects who perform regular physical activity is mainly due to the action that exercise plays on the control of cardiovascular risk factors. In particular, physical training has proved capable of improving lipid profile, reducing blood pressure and body weight, and improving glycemic control in diabetic subjects. In patients with coronary artery disease, combined exercise training, including both aerobic activities and strength training, is currently recommended. However, physical training in patients suffering from ischemic heart disease should be carefully prescribed, in order to maximize the positive effects and minimize the risks. It is also important that physical training programs are conducted in suitable facilities, with appropriately trained staff and with technical equipment suitable to deal with any emergency situations.
