Coronary heart disease represents a big problem today since it represents a big socio-economic problem. In developed countries, it is the leading cause of mortality, despite the fact that mortality from this disease has decreased in the last three decades. It occurs among members of both sexes, although it occurs more often in men in a ratio of 4:1. It causes more death, disability and economic loss than any other disease. Coronary heart disease represents a set of clinical syndromes as a result of which the coronary circulation is changed and the imbalance between myocardial oxygen demand and myocardial oxygen supply, which causes myocardial ischemia. The most common cause of ischemic heart disease is atherosclerotic disease of the coronary arteries. Coronary disease prevention plays an important role here, and it can be divided into primary and secondary prevention. Primary preventive measures refer to the prevention of the clinical manifestation of the disease, and include the prevention of risk factors or their removal, which refers to smoking cessation, healthy nutrition and regular physical activity. Secondary prevention measures are applied to patients who have already been diagnosed with the disease. The role of physiotherapists is to contribute to the implementation of preventive measures through proper education and motivation of patients. Coronary artery disease is also one of the most common causes of cardiac arrest. During a cardiac arrest, there is an inability to pump blood to other parts of the body, which represents an emergency and requires a quick reaction of a person who is near such a patient. The emergency procedure of providing cardiopulmonary resuscitation can help save the life of an accident victim. Knowledge of basic life support algorithms is essential here, which greatly contributes to the possibility of a positive outcome and increases the probability of survival of a person who has experienced a cardiac arrest. Education of healthcare workers and knowledge of the procedures for providing cardiopulmonary resuscitation and using an automatic external defibrillator greatly contributes to the safety of the person providing CPR, which also contributes to the faster reaction needed in such emergencies.
