Abstract：Objective To study the use of warfarin in valvular atrial fibrillation patients and non-valvular atrial fibrillation patients; to observe the rate of reaching international normalized ratio(INR) standard after using warfarin.Methods All 969 cases of hospitalized patients with atrial fibrillation were divided into two groups,valvularatrial fibrillation group(161 cases) and nonvalvular atrial fibrillation group(808 cases).The differences of warfarin utilization rate and success rate with statistical between two groups,and the overall success rate of INR of 307 patients who used warfarin in 969 atrial fibrillation patients were studied.Results Regarding the use of warfarin,there was a statistical difference between valvular atrial fibrillation patients and patients with non-valvular atrial fibrillation (P ＜ 0.05) ; there was no difference of success rate [57.8％ ((93/161) vs 26.5％ (214/808)(P ＞ 0.05) among 307 cases of atrial fibrillation with the use of warfarin.Conclusion The utilization rate of warfarin is low in patients with atrial fibrillation and the INR success rate is low.
