Incidence of complications after cardiac surgery

The leading cause of death worldwide is cardiovascular disease, according to the World Health Organization (WHO), predominating in elderly patients.1 The treatment for these diseases is through surgery, the vast majority being performed by the Unified Health System, medications, changes in eating habits and physical activity. Surgery is a safe procedure for the treatment of coronary artery disease (CAD), as it can be performed in elderly, diabetic patients with low left ventricular ejection fraction.
