Study on 79 patients taking anticoagulant drugs with VKAs who had an INR (International Normalized Ratio) index of more than indicated anticoagulation dose with VKAs therapy.Results: A total of 79 patients, mean age 65.65 ± 12.17 years [33:85], the elderly group is common (73.4%). Patients had hemorrhage disorders account for 22.8%. The INR index had an average value was 5.88 ± 3.0 [3.02– 23.95]; The INR> 5 level group is a higher risk of bleeding than the INR ≤ 5 level group, it’s the statistical significance (p < 0.001). The risk factors such as drugs to treat dyslipidemia, hyperthyroid, amiodarone, beta blocker, prednisone, NSAIDs (Non-steroidal anti-inflammatory), BMI (Body Mass Index), smoke and alcohol that the risk factors of increasing of bleeding when receiving anticoagulants but it’s not statistically significant yet (OR > 1, p > 0.05); These patients using coenzyme Q10 and green vegetable nutrition such as cruciferous vegetables (Brassicaceae, Asteraceae) are quite common (31.6% and 35.4%), its effect on coagulation with vitamin K and cause of the increased in risk of bleeding was statistical significantly with OR = 5.28 (CI: 1.72– 16.17, p < 0.01), and OR = 2.99 (CI: 1.01– 8.80, p < 0.05) respectively.Conclusion: Most patients in over-anticoagulation were the elderly group. Patients had hemorrhage disorders account for 22.8%. The INR> 5 level group was a higher risk of bleeding than the INR ≤ 5 level group with statistical significance. Patients using Coenzyme Q10 and green vegetable nutrition such as cruciferous vegetables (Brassicaceae, Asteraceae) are quite common, its effect on coagulation and cause of the increased risk of bleeding complication with statistical significance.Keywords: risk factors, bleeding, VKAs overdose, INR |
