This 74-year-old gentleman with insulin-dependent diabetes mellitus, hypertension, and coronary artery disease presented with substernal chest pain on exertion and was admitted with T wave inversions in leads V3 and V4. Cardiac cath showed a 95% ostial LAD lesion, a 60% mid LAD lesion, an 80% distal LAD lesion, a 70% proximal D1 lesion, a 40% proximal circumflex lesion, a 90% ostial OM1 lesion, and a 100% proximal RCA lesion; he underwent CABG x3 with a Y graft, SVG1 connecting SVG2 to the LAD, SVG2 connecting the aorta to OM1, and SVG3 connecting to PDA. The patient is a Spanish-speaking only male who is neurologically intact, moving all extremities, getting in and out of bed, and very independent. He had a ventricular fibrillation arrest in the operating room due to an aprotinin reaction, necessitating open cardiac massage and requiring lidocaine and amiodarone use during the code. Medication on admission included Lopressor 50 mg p.o. t.i.d., Lisinopril 40 mg p.o. daily, Aspirin 325 mg p.o. daily, Hydrochlorothiazide/triamterene one tablet daily, Atorvastatin 80 mg p.o. daily, and Lantus 50 cc daily. The patient developed a deep sternal infection with E. coli and was started on Flagyl and Vancomycin for presumed aspiration pneumonia, Imipenem for ID's recommendation, and Nitrofurantoin and Ceftazidime for UTI. He is on Lopressor 25 mg q.6h, Amlodipine 5 mg b.i.d., Lasix 20 mg p.o. b.i.d., Aspirin, Atorvastatin, Lantus, NovoLog, and Diabetes Management. Imipenem and Vancomycin need to be continued for six weeks. He had a small area of erythema on his chest wound, but it is intact and he is being followed by Plastics. He had one brief episode of atrial fibrillation during a coughing spell, but it resolved and he is on antihypertensive medication. He was deemed fit for transfer back to the Step-Down Unit on postoperative day #18.
