[Invasive treatment of acute coronary syndrome in multiple affection of the coronary arteries].

A comparative assessment of the risk of invasive myocardial revascularizations in patients with multiple affection of coronary arteries and acute coronary syndrome (ACS) without stable ST-elevation on ECG was carried out. Group A (n=45) consisted of patients with one-stage revascularization with coronary bypass (CB) during ACS, group B (n=45) - balloon angioplasty /stenting of symptom-determining artery with subsequent CB in the "cold period" (6 months after ACS episode). It is demonstrated that the one-stage procedure (i.e. multiple CB during ACS) is more effective compared with two-stage invasive treatment because of lower lethality and lower rate of CHD complications.
