Although the observed progress in the cardiovascular disease treatment, the incidence of new and recurrent coronary artery disease remains elevated and constitutes the leading cause of death in the developed countries. Three-quarters of deaths due to cardiovascular diseases could be prevented with adequate changes in lifestyle, including increased daily physical activity. New evidence confirms that there is an inverse dose-response relationship between physical activity and cardiovascular disease and mortality risk. However, participation in moderate to vigorous physical activity may not fully attenuate the independent effect of sedentary activities on increased risk for cardiovascular diseases. Physical activity also plays an important role in secondary prevention of cardiovascular diseases by reducing the impact of the disease, slowing its progress and preventing recurrence. Nonetheless, most of eligible cardiovascular patients still do not benefit from secondary prevention/cardiac rehabilitation programs. The present review draws attention to the importance of physical activity in the primary and secondary prevention of cardiovascular diseases. It also addresses the mechanisms by which physical activity and regular exercise can improve cardiovascular health and reduce the burden of the disease.
Core tip: This review describes the benefits of physical activity in primary and secondary prevention of cardiovascular disease. Physical inactivity is related to high blood cholesterol and accumulation of visceral fat, accompanied by low-grade vascular inflammation, which in turn is associated with insulin resistance and atherosclerosis leading to the development of coronary artery disease. In contrast, physical activity decreases vascular inflammation, and improves endothelial function and coronary circulation, preventing myocardial ischemia. Health professionals and policy makers in public health should align strategies to increase participation in physical activity.
