ABSTRACT
OBJECTIVE:
To compare the therapeutic warfarin and aspirin efficacies for treatments of atrial fibrillation (AF) complicated with stable coronary heart disease particularly in older Chinese patients.METHODS:
In our prospective study 101 patients with AF and stable coronary heart disease older than 80 years were randomized into two groups. One group (n = 51) basically received 1.25 mg/day warfarin per os, followed by addition of 0.5 - 1.0 mg/day from day 3 - 5 if the international normalized ratio (INR) was initially < 1.5 and in order to achieve a maintained INR between 1.6 and 2.5 (warfarin group). The second group (n = 50) received 100 mg aspirin per day (control group). All patients were medicated and monitored for a period of 2 years. The primary endpoint was the occurrence of ischemic stroke or systemic embolism, and the composite secondary endpoint was non-fatal myocardial infarction and all causes of death. For safety evaluation, the hemorrhage rates were recorded.RESULTS:
The warfarin medication was superior regarding the overall occurrence of ischemic stroke or systemic embolism as well as non-fatal myocardial infarction and all causes of death outcomes compared to aspirin administration during the 2 years of medication (17.6% vs. 36.0%, p = 0.03), while there was no significant difference of mild (5 vs. 4), severe (2 vs. 1), and fatal (1 vs. 1) hemorrhage incidences between the warfarin and aspirin groups (p > 0.05).CONCLUSION:
Warfarin was found to be more efficacious than aspirin for an anticoagulation therapy of older Chinese patients with AF and stable coronary heart disease.
