[The Multimorbid Patient: Use of New Oral Anticoagulants in Patients with Chronic Kidney Disease].

The Multimorbid Patient: Use of New Oral Anticoagulants in Patients with Chronic Kidney Disease Abstract. Increasing life expectancy in Western countries is associated with a high prevalence of multiple chronic diseases which is defined by the term "multimorbidity". Many of these patients suffer from chronic kidney disease (CKD) and thrombogenic comorbidities such as atrial fibrillation with the need for oral anticoagulation. For decades vitamin K antagonists have been exclusively prescribed for oral anticoagulation. However, due to altered pharmacokinetics and bioavailability of these drugs in CKD, a significant risk of bleeding exists. The introduction of direct oral anticoagulants as a new and promising alternative to vitamin K antagonists was -especially for CKD patients - highly anticipated. However, data from randomized studies are missing for older patients with advanced CKD. Consequently, a careful evaluation of the risk-benefit ratio is recommended for this sensitive patient population.
