Self-Management of Oral Anticoagulation Therapy Improves Long-Term Survival in Patients with Mechanical Heart Valve Replacement

Self-Management of Oral Anticoagulation Therapy Improves Long-Term Survival in Patients with Mechanical Heart Valve Replacement
Heinrich Koertke, MD*, Armin Zittermann, PhD, Otto Wagner, Reiner Koerfer, MD, PhD

 

BACKGROUND: The Early Self-Controlled Anticoagulation Trial has demonstrated that in patients with mechanical heart valve replacement self-management of oral anticoagulation results in less major thromboembolic events than conventional measurement by the general practitioner.

 

RESULTS: Self-management of oral anticoagulation increased long-term survival by 23% (intent-to-treat analysis) and 33% (per protocol analysis), respectively, compared with conventional measurement by the general practitioner. Possible reasons for these advantageous results in the self-management group are fewer thromboembolic events due to a higher percentage of international normalized ratio values lying in the target range compared with the conventional group.

 

CONCLUSIONS: Data indicates that self-management of oral anticoagulation is a promising strategy in order to increase long-term survival in patients with mechanical prosthetic valves.
