Acute coronary syndromes are a frequent cause of hospital admission for patients with coronary artery disease. The pathophysiology of acute coronary syndromes often involves plaque rupture or fissure with platelet aggregation. Recognition of the importance of platelet aggregation resulted in several large randomized trials testing 3 types of platelet antagonists, aspirin, glycoprotein IIb/IIIa inhibitors, and adenosine diphosphate inhibitors. A thorough understanding of the data, risks, and benefits of these therapies is important to optimize treatment of the patient with an acute coronary syndrome. Recognition that there is a great deal of interpatient variability in response to these antiplatelet therapies highlights the need for future research in this area. 相似文献

A simplified approach to the management of non-ST-segment elevation acute coronary syndromes 总被引:5,自引:0,他引:5
Context While current practice guidelines provide an evidence-based approach to management of acute coronary syndromes (ACS), application of the evidence by individual physicians has been suboptimal. Objective To assess and synthesize the evidence regarding optimal management of nonST-segment elevation ACS (NSTE-ACS). Data Sources Systematic searches of peer-reviewed publications were performed in MEDLINE and the Cochrane Database from January 1990 through November 2004, with consultation by content experts. Search terms included antiplatelet therapy, antithrombotic therapy, angiotensin-converting enzyme inhibition, angiotensin receptor blockade, -blockade, hypertension, hyperlipidemia, cigarette smoking, diet, diabetes mellitus, exercise, myocardial ischemia, and coronary artery disease. Study Selection and Data Extraction Criteria for selection of studies included controlled study design, English language, and clinical pertinence. Data quality was based on the publishing journal and relevance to clinical management of NSTE-ACS. Data Synthesis While outcomes of controlled studies support a comprehensive approach in the management of patients with NSTE-ACS, many physicians perceive existing guidelines as lengthy and complex. After risk stratification to identify those patients most likely to benefit from an early invasive vs early conservative strategy, a comprehensive management plan can be assembled through an "ABCDE" approach. The elements of this include "A" for antiplatelet therapy, anticoagulation, angiotensin-converting enzyme inhibition, and angiotensin receptor blockade; "B" for -blockade and blood pressure control; "C" for cholesterol treatment and cigarette smoking cessation; "D" for diabetes management and diet; and "E" for exercise. Conclusion An "ABCDE" approach for the management of NSTE-ACS provides a practical and systematic means to implement evidence-based medicine into clinical practice. 相似文献

目的探讨曲美他嗪联合生脉注射液在非ST段抬高性急性冠脉综合征(NSTEACS)中的应用。方法将选择的46例NSTEACS患者随机分为对照组与治疗组,在常规药物治疗的基础上,对照组加用曲美他嗪治疗,治疗组则在对照组治疗的基础上加用生脉注射液进行治疗。观察并比较两组患者治疗总有效率、治疗前后血浆高敏C-反应蛋白(hs-CRP)、一氧化氮(NO)以及内皮素(ET)水平变化。结果治疗组治疗总有效率为91.30%,显著高于对照组的82.61%,差异有统计学意义(P〈0.05);治疗后两组患者血浆hs-CRP及ET水平均显著降低,NO水平显著升高(P〈0.05),以治疗组变化更为显著(P〈0.05)。结论曲美他嗪联合生脉注射液治疗NSTEACS疗效肯定,可显著改善内皮功能并抑制炎症,疗效优于单用曲美他嗪。 相似文献

目的评价血管性血友病因子(von Willebrand factor,vWF)对判断非ST段抬高的急性冠脉综合征(NSTE-ACS)患者预后的意义。方法70例NSTE-ACS患者,检测基线时、入选12 h及48 h血浆vWF水平。研究的复合终点包括随机入选后30 d内的死亡、心肌梗死或复发心肌梗死以及复发心绞痛。比较发生终点事件与未发生终点事件的患者之间血浆vWF水平的区别。结果①在随访30 d时,22例(31.4%)发生了至少一个终点事件。在有终点事件的患者与无终点事件的患者间,48 h与基线vWF浓度的差值为100±34%比73±33%(P〈0.05)。②在有终点事件的患者与无终点事件的患者间,男性比率为55%比75%(P〈0.05),多支血管病变比率为73%比50%(P〈0.05)。结论非ST段抬高的急性冠脉综合征发病早期48 h内vWF的浓度升高是30 d终点事件的独立预测因素。 相似文献

Admissions to emergency care centres with acute coronary syndromes remain one of the principal burdens on healthcare systems in the Western world. Early pharmacological treatment in these patients is crucial, lessening the impact on both morbidity and mortality, with the cornerstone of management being antiplatelet agents. While aspirin and clopidogrel have been the drugs of choice for nearly a decade, an array of newer, more potent antiplatelet agents are now available or in late stage development. Data are rapidly gathering suggesting these agents have superior anti-ischaemic properties, improving patient outcomes, but that for some agents increased vigilance and appropriate patient selection may be necessary to guard against bleeding complications. In this review, the authors aim to deliver an overview of the changing field of antiplatelet therapy and provide information about the relative risks and benefits of these newer agents, many of which will be entering widespread clinical use imminently. 相似文献

Context The American College of Cardiology/American Heart Association (ACC/AHA) guidelines for the management of nonST-segment elevation acute coronary syndromes (NSTE ACS) recommend early invasive management for high-risk patients, given the benefits with this approach demonstrated in randomized clinical trials. Objectives To determine the use and predictors of early invasive management strategies (cardiac catheterization <48 hours following presentation) in high-risk patients with NSTE ACS and to examine the association of early invasive management with mortality. Design, Setting, and Patients The CRUSADE (Can Rapid Risk Stratification of Unstable Angina Patients Suppress Adverse Outcomes With Early Implementation of the ACC/AHA Guidelines) Quality Improvement Initiative evaluated care patterns and outcomes for 17 926 high-risk NSTE ACS patients (positive cardiac markers and/or ischemic electrocardiographic changes) based on ACC/AHA guidelines recommendations at 248 US hospitals with catheterization and revascularization facilities between March 2000 and September 2002. Main Outcome Measures Use of early invasive management within 48 hours of presentation, predictors of early invasive management, and in-hospital mortality. Results Of the 17 926 patients analyzed, 8037 (44.8%) underwent early cardiac catheterization less than 48 hours following presentation. Predictors of early invasive management included cardiology care, younger age, lack of prior or current congestive heart failure, lack of renal insufficiency, ischemic electrocardiographic changes, positive cardiac markers, white race, and male sex. Patients treated with early invasive management were more likely to be treated with medications and interventions recommended by the ACC/AHA guidelines and had a lower risk of in-hospital mortality after adjusting for differences in clinical characteristics and after comparing propensity-matched pairs (2.5% vs 3.7%, P<.001). Conclusions An early invasive management strategy is not utilized in the majority of high-risk patients with NSTE ACS. This strategy appears to be reserved for patients without significant comorbidities and those cared for by cardiologists and is associated with a lower risk of in-hospital mortality. 相似文献
