The role of statins in the primary and secondary prevention of cardiovascular events is well known. An important adverse event associated with statin treatment is myopathy; intensive physical effort in patients treated with statins increases the risk of muscle injury/myopathy. In this article we discuss the benefits and risks associated with statin treatment in patients undergoing cardiac rehabilitation after acute coronary syndromes and/or coronary revascularization procedures. In our opinion, the benefits of the secondary prevention of coronary heart disease achieved with statins seem to outweigh the hazards associated with statin therapy. The careful selection of patients for both treatment with statins and the gradual intensification of physical training in the course of cardiac rehabilitation appears to constitute an important element of the therapeutic approach.
