До сих пор существует потребность в поиске биомаркеров для раннего прогнозирования и диагностики сердечно-сосудистых осложнений (ССО) у пациентов с ИБС. Цель - определение роли матриксных металлопротеиназ (ММП-1, 8, 9) в риске развития CCО у пациентов с ИБС до и после аортокоронарного шунтирования (АКШ). Методика. В исследование включены 75 больных с ИБС до и после реваскуляризации миокарда методом АКШ, из них 40 мужчин и 35 женщин в возрасте от 45 до 74 лет. Пациенты были разделены на 2 группы: I группа - 25 больных с зарегистрированными ССО после АКШ (острый инфаркт миокарда, ишемический инсульт, тромбоэмболия легочных ветвей); II группа - 50 больных с ИБС без осложнений после реваскуляризации миокарда. Забор крови осуществлялся за сутки до операции, в 1-е, 3-и и 10-е сутки после АКШ. Определение уровня ММП-1, -8, -9 проводилось в сыворотке крови методом твердофазного ИФА, с использованием специфических реактивов «RD Diagnostics Inc.», USA. Результаты выражали в нг/мл. Данные представляли в виде медианы и двух квартилей (Me, Q, Q). Внутри и межгрупповые различия оценивали с помощью критерия Манна-Уитни, коэффициента корреляции Спирмена и критерия c в рамках прикладной программы SPSS №16. Статистически значимыми считали различия между показателями при отклонении нулевой гипотезы и уровне значимости p<0,05. Результаты. Выявлено статистически значимое повышение концентрации ММП-1 и ММП-8 у больных в I группе. Не выявлено значимой динамики ММП-9 у пациентов после реваскуляризации миокарда. Заключение. Полученные результаты свидетельствуют, что уровень ММП-1 2,5 нг/мл и более у пациентов с ИБС является диагностическим критерием риска возникновения ТЭ осложнений. Не установлено связи между повышенным содержанием ММП-8 и наличием осложнений у пациентов после операции. Не выявлено значимой динамики ММП-9 у пациентов после реваскуляризации миокарда. There is still a great need for detection of biomarkers for early prediction and diagnosis of cardiovascular complications (CVC) in patients with CHD. Objective: To determine the role of MMP-1, 8, 9 in the risk of CCO in patients with CHD before and after coronary artery bypass grafting (CABG). Methods. The study included 75 patients with coronary heart disease before and after myocardial revascularization by CABG, including 40 men and 35 women aged from 45 to 74 years. Patients were divided into two groups: I group - 25 patients with CVC registered after CABG (acute myocardial infarction, ischemic stroke, pulmonary thromboembolism Branch); II group - 50 patients with coronary heart disease without complications after myocardial revascularization. Blood sampling was performed the day before surgery, on the 1st, 3rd and 10th days after CABG. Determining the level of MMP-1, 8, 9 in the serum was performed by ELISA using reagents specific «RD Diagnostics Inc.», USA. Results are expressed in ng/ml. Data are presented as medians and quartiles of two (Me, Q25, Q75). Within and between-group differences were evaluated using the Mann - Whitney, Spearman correlation coefficient and c
Aim and Scope: A total of 125 patients suffering from ischemic heart disease (IHD) were examined before and after coronary artery bypass grafting (CABG), there were 79 males and 46 females aged 45-74 years among them. Study blood samplings were performed a day before and then on the 1 st , 3 rd , 7 th , and 12 th day after the surgery. Material and Methods: Intra-and inter-group differences were estimated with Mann-Whitney U-test, Spearman's rank correlation and χ 2 test using application software SPSS v.16. Differences between parameters in case of deviation from null hypothesis and level of significance P < 0.05 were considered to be statistically significant. Result and Discussion: The levels of tumor necrosis factor-α (TNF-α) (χ 2 = 4.28, Р < 0.05, AUC = 0.91), interleukin (IL)-10 (χ 2 = 3.97, P < 0.05, AUC = 0.829), and matrix metalloproteinases (MMP)-1 (χ 2 = 6.66, Р < 0.01, AUC = 0.963) were defined to be early and excessively increased before CABG and in early postsurgical period in patients with post-operative thromboembolic complications, suggesting the patients with IHD have a high risk of the complications mentioned above after CABG surgery. The association of TNF-α hyperproduction (above 30 pg/ ml) on the 1 st day after CABG and hemorrhagic complications development in patients after CABG was revealed (χ 2 = 4.0, P < 0.05, AUC = 0.776). Conclusion: The maximum increasing of IL-6 level inpatients of all examined groups was present immediately after surgery, which was caused by surgical injury. The analysis of MMP-8 and MMP-9 did not reveal a correlation between their increased levels and the presence of complications in the patients after the surgery. The expression of the first tissue inhibitor of metalloproteinases was moderately increased in patients of all groups with no significant difference in its levels between the groups
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
