Abstract
This chapter will concisely summarize the following sections of the anticoagulation guidelines (for management of deep vein thrombosis [DVT]/pulmonary embolism [PE], see chapter on DVT/PE):
-
1.
Prevention of venous thromboembolism (VTE).
-
2.
Antithrombotic therapy in atrial fibrillation (AF).
-
3.
Antithrombotic therapy in valvular heart disease—native and prosthetic.
-
4.
Management of elevated international normalized ratios (INRs) or bleeding in patients receiving vitamin K antagonists (VKA).
-
5.
Managing anticoagulation therapy in patients requiring invasive procedures (1).
The recommendations from the American College of Chest Physicians (ACCP) employ a grading system originally described in 2001. If experts are very certain that benefits do, or do not, outweigh risks, burdens, and costs, they will make a strong recommendation (grade 1). If they are less certain of the magnitude of the benefits and the risks, burdens, and costs, and thus of their relative impact, they make a weaker grade 2 recommendation. Consistent results from randomized clinical trial (RCTs) generate grade A recommendations. Observational studies with very strong effects or secure generalizations from RCTs generate grade C+. Inconsistent results from RCTs generate grade B recommendations and observational studies generate grade C recommendations.
