Resumen

The aim of this study was to define influence of completeness heart revascularization on a functional condition of myocardium at ischemic cardiomyopathy. Materials and methods. 61 men and 5 women aged from 46 till 73 years with the diagnosis an ischemic cardiomyopathy were investigated before and after coronary angioplasty (EDV LV -256,1 ± 7,4 ml, EF LV - 36,1 ± 1,1%). 46 patients had at receipt CHF with NYHA functional class 4, 20 - CHF with NYHA functional class 3. Functional status (6-minute walking test) - 109,7 ± 20,5 m. Chronic total occlusion was the major type of coronary artery disease (92 of 176 epicardial branches). By means of echocardiography and quantitative gated SPECT estimated dynamics of systolic and diastolic function, change of perfusion, thickening and myocardial movement. Results. The full revascularization managed to be executed to 32 patients, incomplete - to 34 patients (34 occluded arteries didn't manage to be opened). In the whole group the 6-minute walking test increased to 268,2 ± 19,9 m (p < 0,001), EF LV grew to 39,9±1,1% (p < 0,01) due to reduction of end systolic volume, degree of mitral regurgitation decreased from 1,6 ± 0,1 to 1,2 ± 0,1 (p < 0,007), pulmonary artery pressure decreased from 39,1 ± 1,7 to 32,1 ± 1,2 mm Hg (p < 0,01). Distinctions in dynamics of the main functional indicators between groups of complete and incomplete revascularization it isn't revealed. The factor of expressiveness of collateral blood flow in the region of occluded arteries probably compensates violation of an antegrade blood flow and defines a myocardial condition. Conclusion. The volume of myocardial revascularization at patients with ischemic cardiomyopathy isn't defining factor in a clinical condition of them after executed percutaneous coronary intervention.
