Coronary revascularization of patients before non-cardiac surgery today is actual medical treatment. The reason is prolongation of average age of our population, arising of percutaneous coronary interventions (PCI), coronary artery bypass grafts (CABG) and non-cardiac surgery in the elderly. Cardiologist has to resolve two main problems in these patients: 1. When one does indicate the revascularization? 2. What to do with patients after these revascularizations? The resolution is stratification of the risk of ischemic heart disease, realization of PCI or CABG in high risk patients, correct medical treatment and establishing risk and timing of non-cardiac surgery.
