Target anticoagulation levels?

In this large cohort of 4202 patients followed in an anticoagulation clinic for MI, atrial fibrillation, or mechanical heart valves, researchers determined untoward effects (major thromboembolism or major hemorrhage) occurred at a rate of 4% per year. The optimal intensity (fewest number of untoward events) for heart valves was an INR 2.5-2.9, for atrial fibrillation was 3-3.4, and for MI was 3.5-3.9 (abstract).
