[Effectiveness of early invasive strategy of treatment of angina of new onset].

Aim of the study was to assess effectiveness of early invasive strategy of treatment of angina of new onset (ANO). We conducted comparative assessment on invasive and noninvasive risk estimation in 106 patients admitted to N.V.Sklifosofsky Institute of Urgent Aid in 2003-2007. Percutaneous coronary interventions (PCI) on symptom related artery (SRA) within single procedure were carried out in 74 cases (70%), indications to coronary artery bypass surgery were detected in 16 cases (15%), in 16 more cases conservative treatment was used. The data obtained showed that it is rational to consider ANO as unstable angina in all cases including those without progression. Visualization of coronary arteries gives possibility to define significance of SRA and zone at risk of injury, determine indications to myocardial revascularization, and avoid inadequacy of noninvasive assessment of risk and choice of treatment tactics. The method of choice in the treatment of patients with ANO is PCI performed during single procedure. Detection of indications to coronary artery bypass surgery in low risk patients and in absence of progression confirm necessity of routine use of invasive strategy which provides timely pathogenetic treatment. Absence of indications to myocardial revascularization detected in sporadic cases provides possibility to avoid groundless hospitalizations.
