Is Low Anticoagulation Intensity More Beneficial For East Asians With Mechanical Heart Valves? A Meta-Analysis

For the East Asian patients using the low thrombogenic risk mechanical valves (bileaflet prothetic valve and Medtronic-Hall tilting leaflet prothetic valve), excellent results can be achieved by adopting the anticoagulation intensity(median INR:2.05-2.25)which is lower than the recommended intensity
