STRATIFICATION OF CHRONIC ISCHEMIC HEART DISEASE DEPENDING ON DIAGNOSIS METHODS AND TREATMENT WAYS

Chronic stable angina in about 50% of all patients is usually caused by occlusion of at least one large epicardial coronary artery by an atheromatous plaque. Angina pectoris results from a mismatch in myocardial oxygen demand, leading to myocardial ischaemia. The indications for coronary revascularisation continue to evolve as scientific and technical advances improve both the results obtained with optimal drug therapy and the methods of revascularisation. A critical issue is the extent to which all forms of therapy are used appropriately based on guidelines and appropriateness criteria, especially with regard to cost and access to care. If symptoms and quality of life do not improve with drug therapy alone, an initial trial of drug therapy with the option to proceed to revascularisation is appropriate. Overall, these results support the recommendations and raise questions about the feasibility of coronary revascularisation, particularly percutaneous coronary intervention
