Patient: Winston Waller
Physician: Morris Johnston, MD
August 1, 2018

History

This patient is a 73-year-old male nonsmoker with type 2 diabetes mellitus and hypertension. He presented to this ED with shortness of breath and was found to have an acute infarction of the anterior wall of his heart showing an ST elevation. He developed several complications, including renal failure from a combination of cardiogenic shock and toxicity from the dye used for emergency catheterization of his heart.

Hemodialysis was started during this hospitalization because of his renal failure. After spending almost a month in the hospital and developing severe deconditioning, he was discharged to a subacute rehabilitation facility.

Examination

While he was there he was noted to have symptoms consistent with mild depression, as well as a prior history of a major depressive episode in 2016. Mirtazapine (Remeron) 25 mg/day was started.

He was transferred to a skilled nursing unit for another month of rehabilitation management of his medical conditions and then discharged home to the care of his wife.
