Vai trò của INR do bệnh nhân tự đo bằng Coagulacheck XS trong xử trí chống nôn sau thay van tim cơ học

Patients carrying the mechanic heart valve(s) need AVK through out the lifetime to maintain a INR therapeutic range of 2.5 - 3.5 in spite of difficult access to hospital lab. The study aims to evaluate the correlation and the agreement of INR self-monitoring with portable CoaguCheck XS versus INR determined by CA-1500 coagulation analyser in hospital lab. Results show that there are a strong, close correlation and a good agreement between the values of INR determined by the above two methods. Thus, INR self-monitored with portable CoaguCheck XS is reliable for anticoagulation management at home after mechanic cardiac valvular replacement.
