Abstract
The American College of Chest Physicians (ACCP) guidelines addressing antithrombotic therapy, first published in 1986,1 have been updated about every 3 years. The eighth edition of the guidelines [now called “Antithrombotic and Thrombolytic Therapy: American College of Chest Physicians Evidence-Based Clinical Practice Guidelines (8th Edition)]” is published as a special supplement of CHEST this month.2 Over the past 2 decades, these guidelines have adapted to trends in evidence-based medicine and helped to raise the standards for guideline methodology.345678 The eighth edition has, judging by the numerous daily requests for the publication date, been one of the most anxiously anticipated products of the ACCP.
This document provides an extensive update of evidence-based guidelines for the management of thromboembolic conditions affecting the venous and arterial systems (including the coronary, cerebral, and peripheral arteries), and the cardiac chambers, including native and prosthetic valves. The guidelines also address the management of thromboembolism in the pediatric population and during pregnancy, the management of patients who are treated with anticoagulants and require bridging therapy because of an intercurrent invasive procedure, and the management of heparin-induced thrombocytopenia. We also include chapters reviewing the pharmacology of the approved anticoagulants (heparin, low-molecular-weight heparins, fondaparinux, hirudin, bivalirudin, and argatroban), antiplatelet drugs (aspirin, clopidogrel, ticlopidine, dipyridamole, and the glycoprotein IIb/IIIa antagonists), and thrombolytic agents (streptokinase, tissue plasminogen activator, and the tissue plasminogen activator analogs tenecteplase and retoplase). These introductory chapters include recommendations for the dosing and monitoring of anticoagulants and antiplatelet agents.
Rank | Definition |
|---|---|
| 1 | This guideline is new and represents the best available evidence at this time. It will be reviewed on an annual basis to determine if it remains current. |
| 2 | This guideline is reviewed on an annual basis and there have been new studies published since the guideline was developed. However, the Health and Science Policy (HSP) Committee determined that these studies are not sufficient to warrant changing the guideline at this time. The information contained in this guideline provides the user with the best evidence available at the time the guideline was published. Readers are encouraged to search the current literature as a supplement to using this guideline. |
| 3 | This guideline is reviewed on an annual basis. The HSP Committee determined that new studies have been published that warrant an update of the (fill in) chapter/section of this practice guideline. The HSP Committee also determined that the remainder of the chapters/sections does not require updating and these recommendations remain current. |
| 4 | This guideline is reviewed on an annual basis. The HSP Committee determined that new data are available that are sufficient to potentially change guideline recommendations and a full revision is warranted. |
| 5 | This guideline has been reviewed on an annual basis. The HSP Committee has decided it is outdated; however, it has been retained for historical and/or educational purposes. These guidelines should be used with caution for clinical decision-making purposes. |
The evidence-based practice guidelines published by The American College of Chest Physicians (“ACCP”) incorporate data obtained from a comprehensive literature review of the most recent studies available at the time of publication. Guidelines are intended for general information only, are not medical advice, and do not replace professional medical care and physician advice, which always should be sought for any specific condition. Furthermore, guidelines may not be complete or accurate because new studies that may have become available late in the process of guideline development may not be incorporated into any particular guideline before it is disseminated. ACCP and its officers, regents, governors, executive committee, members and employees (the “ACCP Parties”) disclaim all liability for the accuracy or completeness of a guideline, and disclaim all warranties, express or implied. Guideline users always are urged to seek out newer information that might impact the diagnostic and treatment recommendations contained within a guideline. The ACCP Parties further disclaim all liability for any damages whatsoever (including, without limitation, direct, indirect, incidental, punitive, or consequential damages) arising out of the use, inability to use, or the results of use of a guideline, any references used in a guideline, or the materials, information, or procedures contained in a guideline, based on any legal theory whatsoever and whether or not there was advice of the possibility of such damages.
