Item Effect of an Educational Programme on Knowledge of Patients with Replaced Heart Valves Regarding Warfarin Therapy.(Al Neelain University, 2017) Mohammed Khalid Hussien KhalidBackground: Since the inception of heart valve replacement surgical operations, the lives of millions of patients with damaged heart valves have been saved. However, the replaced valves constitute triggering factors for intravascular thrombosis in these patients. Thus, anticoagulation medication becomes a necessity as a lifelong management. Warfarin is one of the preferred anticoagulants in common use with the advantage of being orally administered. However, it has a narrow therapeutic range so much so that bleeding or coagulation is an easily reached complication. Therefore, the drug should be kept under tight control that depends on the measurement of international normalized ratio and monitoring of the early warning signs and symptoms. Successful management of the patient depends on the full awareness of the treating personnel and the patient as the principal stakeholder about the drug and its side effects. This goal can be achieved through patient education about the drug, which is considered in many anticoagulation systems as a part and parcel of the medical management.
