[Is always chronic total occlusion indication for recanalization in patients with multi-vessel disease].
The issue of recanalization chronic total occlusion (CTO) up today stays unsolved. Existence of viable myocardium in the CTO basin is regarded to be one of the proofs in cases of transitory ischemia or in the state of hibernation. But, the question of CTO opening in presence of acinetic segments is still under discussion. The aim of our study is testing assumption that CTO recanalization in the presence of other stenotic arteries, improves global and regional contractility of myocardium. One hundred and twenty patients with MI after one month were enrolled. To diagnose viability of myocardium 72% of patients went through stress-echocardiography with small dozes of dobutimin. After, all patients were divided into two groups: who have to undergo complete revascularization (Group I- 35,5%), and those who have to undergo only CTO revascularization (Group II- 64,5%). There were no significant statistic differences in hemodynamic parameters between groups. In case of multi-vessel disease restoration of antegrade flow in CTO caused to block of CAD attacks and symptoms of congestive heart failure. Therefore, results of the study let us state existence of CTO as indication for angioplasty of infarct-related artery.
