This case involves a middle-aged male patient who had a medical history significant for diabetes and obesity who was being treated for a cardiovascular condition with a diuretic medication. The Plaintiff presented at the defendant nephrologist’s office after undergoing a series of lab tests, one of which revealed an imbalance in his blood urea nitrogen and serum creatinine. The nephrologist immediately discontinued the patient’s medication, without consulting with his cardiologist or ordering regular blood work to monitor the patient’s condition once the drug was discontinued. After a few weeks, the patient began to experience serious cardiovascular complications, including congestive heart failure, which eventually culminated in cardiac arrest. As a result, the patient was seriously and permanently injured, and will require a lifetime of ongoing care.
