Background In contrast with the setting of acute myocardial infarction, there are limited data regarding the impact of diabetes mellitus on clinical outcomes in contemporary cohorts of patients with chronic coronary syndromes. We aimed to investigate the prevalence and prognostic impact of diabetes according to geographical regions and ethnicity. Methods and results CLARIFY is an observational registry of patients with chronic coronary syndromes, enrolled across 45 countries in Europe, Asia, America, Middle East, Australia, and Africa in 2009–2010, and followed up yearly for 5 years. Chronic coronary syndromes were defined by ≥1 of the following criteria: prior myocardial infarction, evidence of coronary stenosis >50%, proven symptomatic myocardial ischaemia, or prior revascularization procedure. Among 32 694 patients, 9502 (29%) had diabetes, with a regional prevalence ranging from below 20% in Northern Europe to ∼60% in the Gulf countries. In a multivariable-adjusted Cox proportional hazards model, diabetes was associated with increased risks for the primary outcome (cardiovascular death, myocardial infarction, or stroke) with an adjusted hazard ratio of 1.28 (95% confidence interval 1.18, 1.39) and for all secondary outcomes (all-cause and cardiovascular mortality, myocardial infarction, stroke, heart failure, and coronary revascularization). Differences on outcomes according to geography and ethnicity were modest. Conclusion In patients with chronic coronary syndromes, diabetes is independently associated with mortality and cardiovascular events, including heart failure, which is not accounted by demographics, prior medical history, left ventricular ejection fraction, or use of secondary prevention medication. This is observed across multiple geographic regions and ethnicities, despite marked disparities in the prevalence of diabetes. ClinicalTrials identifier ISRCTN43070564
Цель исследования: улучшить результаты хирургического лечения ишемической болезни сердца с помощью исполь зования высокой эпидуральной блокады на основании оценки диастолической функции миокарда в предоперацион ном и раннем послеоперационном периодах. Материалы и методы: больные ишемической болезнью сердца (61 па циент), которым была выполнена операция коронарного шунтирования. В зависимости от методики анальгезии пациенты были разделены на 2 группы. Основную группу составили 30 больных, которым в раннем послеоперацион ном периоде проводилась высокая эпидуральная блокада. В группе контроля (31 пациент) использовался традицион ный метод обезболивания парентеральным введением наркотических анальгетиков. В динамике выполнялось ЭХО КГ исследование, при котором исследовались показатели трансмитрального потока. Также оценивали клиническое течение послеоперационного периода и длительность пребывания в отделении реанимации. Результаты: наличие ди астолической дисфункции исходно выявлено практически у всех больных. В раннем послеоперационном периоде в основной группе отмечено достоверное улучшение диастолической функции миокарда на фоне высокой эпидураль ной блокады. В группе контроля улучшения показателей, характеризующих диастолическую функцию левого желу дочка, не наблюдалось. Эти больные также требовали более длительного пребывания в специализированном реани мационном отделении. Заключение: использование эпидуральной блокады в послеоперационном периоде приводит к улучшению диастолической функции миокарда левого желудочка. Ключевые слова: диастолическая дисфункция, эпидуральная блокада, коронарное шунтирование.Objective. To improve the outcomes of surgical treatment of coronary heart disease, by using high epidural block on the basis of evaluation of myocardial diastolic function in the preoperative and early postoperative periods. Materials and methods. 61 patients with coronary heart disease underwent coronary bypass surgery. According to the methods of analgesia, the patients were divided into 2 groups. A study group included 30 patients who had undergone high epidur al block in the early postoperative period. A control group comprised 31 patients, wherein the conventional method for analgesia was applied through the parenteral administration of narcotic analgesics. Follow up EchoCG was made, by examining the parameters of transmitral flow. The clinical course of a postoperative period and the length of stay in intensive care units were estimated. Results. Baseline diastolic dysfunction was detected in practically all patients. In the early postoperative period, the study group showed a significantly better myocardial diastolic function during high epidural block. In the control group, there was no improvement of the parameters characterizing left ventricular dias tolic function. These patients longer stayed in a specialized intensive care unit. Conclusion. The postoperative employ ment of epidural block results in improved left ventricular diastolic function. Key words: diastolic dysfunction, epidur al block, coro...
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.
