Исследование проведено на 284 крысах. Трансмиокардиальная реваскуляризация (ТМР) моделировалась с использованием стандартной внутримышечной иглы, Nd:YAG лазера, радиочастотного генератора с игольчатым электродом. Изучение сосудистой плотности (окраска эндотелиальной щелочной фосфатазы) и перфузии миокарда проводилось через 1, 2, 4 и 8 нед после ТМР. Максимальное увеличение сосудистой плотности наблюдалось на 4-й нед. В группах с радиочастотной ТМР и Nd:YAG ТМР удельный сосудистый объем увеличился в 5 раз (26,9 ± 1,9% и 22,2 ± 1,7% соответственно; Р &lt; 0,05) по сравнению с контрольной группой (4,9 ± 1,6%). В группе с механической ТМР удельный сосудистый объем увеличился незначительно (6,1 ± 1,3%). Увеличение накопления 99mTc-myoview происходило в группе с радиочастотной ТМР на 8-й нед и составило 2,82 ± 0,31% (Р &lt; 0,05) и 1,68 ± 0,21% в контрольной группе. Анализ сосудистой плотности указывает на близкую эффективность лазерной и радиочастотной трансмиокардиальной реваскуляризации. Радиочастотная ТМР вызывает увеличение сосудистой плотности и улучшение миокардиальной перфузии в ишемизированном миокарде.</p></abstract><trans-abstract xml:lang="en"><p>Conducted benchmark analysis of influence to mechanical punctures, transmyocardial radiofrequency influence and lazer radiating on myocardium. Study is conducted on 284 rats. Transmyocardial revascularization (ТМR) was executed with use intramuscular needle, Nd:YAG lazer, radiofrequency generator with needle electrode. Study of vascular density and myocardial perfusion was conducted through 1, 2, 4 and 8 weeks. Maximum increasing vascular density was observed on 4 week. In groups with radiofrequency TMR and Nd:YAG TMR specific vascular volume is enlarged in 5 once (26,9 ± 1,9% and 22,2 ± 1,7%, accordingly; Р &lt; 0,05) in contrast with the checking group (4,9 ± 1,6%). In the group with mechanical ТМР specific vascular volume is enlarged small (6,1 ± 1,3%). Increasing an accumulation 99mTc-myoview in the group with radiofrequency TMR occurred on 8 week by comparing with the checking group, it has formed 2,82 ± 0,31% (Р &lt; 0,05) and 1,68 ± 0,21% accordingly. Conclusion: Analysis of vascular density points to alike efficiency of lazer and radiofrequency transmyocardial revascularization. Radiofrequency ТМR causes an increasing vascular density and improvement myocardial perfusion in ischemic myocardium.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ишемическая болезнь сердца</kwd><kwd>трансмиокардиальная реваскуляризация</kwd><kwd>радиочастотная энергия</kwd><kwd>лазер</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ischemic heart disease</kwd><kwd>transmyocardial revascularization</kwd><kwd>radiofrequency energy</kwd><kwd>laser</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Chu V., GiaidA., Kuang J. et al.
