Background. The prevalence of chronic heart failure in the world is increasing; however, it stabilizing developed countries. One reasons for this stabilization an improvement acute coronary syndrome treatment and revascularization. Revascularization patients with syndromes without signs left ventricular dysfunction less effective. promising methods assessing detection electrical mechanical dyssynchrony myocardium (DM). However, has not been sufficiently studied artery (CA) disease. purpose was to assess relationship between myocardial degree occlusion disease who underwent Materials methods. hundred thirty-four (35 infarction 99 syndromes) angiography revascularization arteries were included study. According results angiography, divided into 3 groups: 12 had unchanged CA (group 1), 17 atherosclerotic lesions 2), 105 occlusion. Among those occlusion, 10 people than 50 %, 26 from 80 36 more 33 complete at least one artery. In all patients, parameters DM determined by ultrasound method. Results. first group, (25 %) DM, second — 4 (23.5 %), group 42 (40 DM. detected 18 (53 cases. Septal posterior wall motion delay (SPWMD) did differ significantly comparison groups; increased 64.8 ± 43.2 ms compared 40.8 13.1 (p < 0.05). SPWMD a significant correlation (r = 0.254, p 0.009). interventricular significantly, 61.3 40.5 33.4 3.4 Left filling time shorter incomplete (47.3 10.4 vs. 54.2 5.7 ms, respectively; ejection different groups, but correlated 0.241, 0.013). early deceleration, beginning QRS complex peak systolic velocity significantly. longer (32.6 8.5 ms), 0.26, 0.007). Conclusions. A third study frequency diagnosed half manifested itself SPWMD, increase period pre-ejection aorta and, as result, delay. An also found associated diastolic reduced time.
