Incidence of Thromboembolism After Stopping Anticoagulant Therapy

摘要: Anticoagulant therapy was discontinued because of hemorrhage on 74 occasions and stopped electively 166 others, the incidence subsequent thromboembolism in these two populations compared. Patients were placed low-, intermediate-, or high-risk categories, depending presence absence factors previously shown to be associated with significant differences incidence. The proportion patients "hemorrhage" "elective" who fell into each category similar comparable other relevant respects. Comparison by means a chi-square contingency analysis failed show any relapse rates during part 16-week follow-up period. Stopping anticoaguant is not therefore risk which demonstrably greater than that observed after discontinuing treatment electively.
