Background: There is no agreement regarding the revascularization of patients with chronic total occlusions (CTO) and signs of ischеmia. Controlled randomized trials did not show prognostic benefit of revascularization. But supposed consequences of «closed» artery are dilatation of left ventricle (LV) and deterioration of LV systolic function.
Methods: 15 patients with isolated CTO of left anterior descending artery (LAD) were included. All patients had positive exercise stress echocardiography (SE) with ischemia in LAD zone. 36% patients met high risk criteria of SE (decrease of LV ejection fraction (EF)). All patients had medical treatment and did not get any revascularization. Mean follow-up period was 8.8 years. Diastolic diameter, diastolic volume, systolic volume of LV were assessed. Exercise SE was performed, EF and wall motion score index (WMSI) were estimated before and after the test.
Results: Diastolic diameter, diastolic volume reduction and systolic volume reduction were observed among patients without revascularization (p ................
