Abstract

Subjects and Methods: Patients after mechanical valve replacement at The Cardiovascular imaging and exploring Department of Hue Central Hospital. Cross- sectional descriptive study. Results: Problems on using anticoagulants: taken regularly (97.36%), right dose (92.10%), stopped abruptly (9.64%). Using of other drugs that is the risk of bleeding when combined with anticoagulants (12.28%), arbitrarily used more other drugs without consulting your doctor (21.05%), using the foods reduces the effect of the drug (28.94%). Understanding of patients after valve replacement: Most patients know that heavy exercise is not good, using other drugs (except anticoagulants) are recommended by doctors, re-examination is on time (over 80%) the rate of re-examinations due to chest pain (70.58%), dyspnea (81.81%) and increased edema (71.42%). 82.35% of patients with bleeding gums re-exam, hematemesis (66.66%), epistaxis (25%). 50, 88% of patients do not know what disease they have, what kind of surgery (54.39%), the reason for INR test (56.15%), do not know of anticoagulant interactions with other drugs and why anticoagulants must be used at a rate of 95.62% and 94.74% respectively খাদ Navigation K Conclusion: The majority of patients after mechanical valvular replacement know how to use drugs as well as how to take care for themselves, but there are still many cases who are not fully understand their disease as well as treatment, caring after mechanical vavular replacement.
