Стресс-эхокардиография в оценке отдаленных исходов после чрескожных коронарных вмешательств у больных со стабильной ишемической болезнью сердца

Aim. To study the possibilities of stress echocardiography (EchoCG) in the assessment of clinical state of patients after percutaneous coronary intervention (PCI). Material and methods. We included into this study 80 patients with stable ischemic heart disease. After preliminary examination, all patients underwent PCI. Stress EchoCG was carried out in 6 and 12 months after PCI. Results. Clinical effect assessed in 12 months after revascularization was good in 90 % of patients. We registered significant increase of exercise capacity (from 97 to 118 W; p=0.001), increase of double product (from 232 to 275; p=0.009), decrease of myocardial ischemia volume (regional contractility impairment index before PCI 1.36, a year after PCI 1.16; p=0.001). The incidence of restenosis was 7.5%. Restenosis was accompanied by a deterioration of clinical status of patients (silent myocardial ischemia, angina recurrence). The accuracy of stress echocardiography in detecting myocardial ischemia in patients after PCI was 94 %. Conclusion. Stress EchoCG has high diagnostic accuracy for detection of myocardial ischemia in patients after PCI during the first 12 months after revascularization.
