Objectives: ST-segment elevation myocardial infarction (STEMI) can be associated with many conduction disturbances including complete atrioventricular block (CAVB). CAVB complicating STEMI resulted in an increased mortality before the modern era of primary percutaneous coronary intervention (PCI). The aim of this study was to ascertain the rate and risk factors for CAVB in STEMI patients undergoing rapid reperfusion with PCI. Methods: We analyzed 223 patients presenting with STEMI. Patient characteristics, procedural characteristics, and in-hospital data were compared between patients with and without CAVB. Results: Out of 223 patients, 174 underwent PCI; the majority (87%) was African-American. CAVB was present in 8 patients (4.6%), and 6 of them had RCA occlusion. Independent predictors of CAVB included diabetes mellitus, female gender, lower systolic and diastolic blood pressure, and inferior-lateral/lateral STEMI. Ten patients (5.7%) required temporary pacing at presentation; only 1 patient required permanent pacing before discharge. No patient with anterior STEMI developed CAVB. Conclusions: The incidence and in-hospital mortality rate of CAVB in patients with STEMI who underwent primary PCI was reduced when compared to data from the thrombolytic era. This may be due to faster flow recovery in the infarct-related artery achieved with PCI.
Цель исследования. Изучение видового состава и инфицированности клещей-переносчиков возбудителей клещевых инфекций на территории Кемеровской области. Материалы и методы. Изучены морфологические признаки 1295 экземпляров клещей рода Ixodes, собранных с растительности области. Для определения роли клещей рода Dermacentor исследовано 1867 клещей разного вида. Определение видовой принадлежности 186 клещей в суспензиях проводили с использованием разработанной методики на основе метода мультипрайм-ПЦР в реальном времени для генотипирования клещей разных видов. Инфицированность 409 клещей, собранных с растительности, и 186 экземпляров, снятых с пострадавшего населения, возбудителями клещевого энцефалита (КЭ) иксодовых клещевых боррелиозов (ИКБ), гранулоцитарным анаплазмозом (ГАЧ), моноцитарным эрлихи
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.
