You can treat his hpothyroidism with thyroid replacement and continue the amiodarone or stop the amiodarone. His atrial fibrillation will likely recur in this case, as his ejection fraction is low. He may be able to use other medications such as tikosyn, dronaderone or sotalol to keep him in rhythm. If he is not symptomatic with the atrial fibrillation he may simply need to be rate controlled and anticoagulated with coumadin.
What is the etiology of his cardiomyopathy?
Thank you so much for the answer. His CHF is believed to be a result of previously untreated or silent MI 's. His coronaries were badly atherosclerotic, not stentable. His PMH includes controlled hypertension, controlled type 2 DM. No hypercholesterolemia. He has history of poor circulation in his legs, and when the grafts were taken from his leg, the first leg did not have good enough veins for grafting. Not sure why they did not take mammary vessels. Any additional advice is greatly appreciated.
