Fact vs. Fiction About Anticoagulants
While some people have strong feelings about the risks of anticoagulants, warfarin is one of the most frequently prescribed drugs in the U.S., with more than 17.8 million prescriptions dispensed annually.1 New medications are also being introduced. A significant percentage of patients undergoing mitral valve surgery also have atrial fibrillation (AF), which requires patients to be on anticoagulation.2 Fortunately, St. Jude Medical® mechanical heart valves have been studied for over 25 years and consistently demonstrate low anticoagulant-related complications.3,4
Studies have shown that anticoagulation can be managed safely for patients of all ages and in fact, perform well in selected older patients with no increased risk of bleeding or thromboembolism.5
Anticoagulation-related complications can be further reduced through patient self-testing. A randomized study showed a reduced complication with international normalized ratio (INR) self-management when compared to conventional management in the clinic.6 INR is a blood test that measures the time it takes for blood to clot and compares it to an average.
St. Jude Medical is a strong supporter of patient self-testing and works with Philips Remote Cardiac Services and HemoSense to provide patient self-testing services to physicians and patients with mechanical heart valves. Visit inrselftest.com or hemosense.com to learn more.
