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 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 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
