Abstract:
AIM:To explore the effects of different intensity of warfarin on patients with coronary atherosclerotic heart disease complicated with atrial fibrillation.METHODS:One hundred and seven cases of coronary heart disease complicated with atrial fibrillation patients in our hospital were selected and were randomly divided into experimental group (n =54) and control group (n =53) by random number table.The experimental group (low intensity) received initial amount of warfarin for 1.25 mg/d,and NR monitoring 24 h after treatment,if INR< 1.4,3-5 mg/d increased by 0.5-1.0 mg/d,monitoring one time per week,INR maintained within 1.4-2.0.INR of the control group (medium intensity) maintained within 2.0-2.6.One month monitoring after INR stabilized.All patients were treated for about 4 weeks,and warfarin was maintained at a dose of 1.25-7.5 mg/d.The primary and secondary end points and bleeding events were observed and compared after 2 years of treatment.RESULTS:The INR of the experimental group and the control group were 1.71 ± 0.38,2.36 ± 0.35,respectively.The ratio of total bleeding event of the experimental group and the control group was 22.2% and 41.5%,respectively.Those of the experimental group were lower than those of the control group,and the difference was all statistically significant (P< 0.05).CONCLUSION:The efficacy of low-intensity warfarin in the treatment of coronary atherosclerotic heart disease complicated with atrial fibrillation is comparable to that of moderate-intensity warfarin therapy,but low-intensity warfarin shows better saftey.
