Quiz
Two days ago you admitted a 72-year-old woman with end-stage renal disease on dialysis who had developed new-onset atrial fibrillation causing a mild acute diastolic congestive heart failure exacerbation. Transthoracic ECG showed a preserved left ventricular ejection fraction and no significant valvular disease. After two sessions of dialysis in the hospital and initiation of a beta-blocker for control of her heart rate, she is stable and ready for discharge. Her discharge weight is 75 kg.
Which of the following recommendations should you make to this patient regarding anticoagulation for prevention of stroke and systemic embolism from atrial fibrillation?
A. Take warfarin with a international normalized ratio goal of 2.5.
B. Take apixaban 2.5 mg twice a day.
C. Take apixaban 5 mg twice a day.
D. Discuss the risks/benefits of various treatment approaches with the patient, and involve the hospital pharmacist as well as the patient’s nephrologist, cardiologist, and/or primary care provider in the decision making process to reach a consensus and to ensure a safe follow-up plan.
The best answer is D. While A, B, and C are all reasonable approaches based on the available data and current guidelines, the best approach is to involve the patient and the multidisciplinary team in the decision making process. When more clinical trial data becomes available in the future, the optimal approach to managing patients such as this one may become clearer, but until then it makes sense to take into account individual patient characteristics and patient preferences.
