Consider the following medical report that includes the patient's historical health records. Use it to predict the disease that the patient is high likely exposed to. 

 Medical Report: history of present illness: this is a 65-year-old white male with coronary artery disease, status post cabg/avr, history of congestive heart failure, diabetes mellitus, chronic renal insufficiency, peripheral vascular disease, status post right femoropopliteal bypass graft, bladder carcinoma, mrsa who developed ischemic ulcers of the left foot about two months prior to admission. the patient had been hospitalized at the in on the medical service for a supratherapeutic inr and ischemic left foot. arteriogram done at that time showed that the patient had nonreconstructable disease. the patient was discharged home and followed as an outpatient. three weeks prior to admission the patient developed increasing pain in his left foot. he presented to the where x-rays showed probable osteomyelitis with air in the soft tissues. the patient requested a transfer to the for evaluation and treatment by dr. . past medical history: 1. coronary artery disease, myocardial infarction x 3; cabg/avr in . positive persantine mibi study in led to a transthoracic echocardiogram showing an ejection fraction of 40%. cardiac catheterization on showed patent grafts and no intervention was necessary. 2. congestive heart failure. 3. diabetes mellitus. 4. chronic renal insufficiency. 5. gi bleed secondary to aspirin. 6. bladder cancer. 7. hypercholesterolemia. 8. nephrolithiasis. 9. rheumatoid arthritis. 10. supratherapeutic inr of 6 during hospitalization. 11. mrsa foot culture . 12. rheumatoid arthritis. 13. chronic anemia. 14. peripheral vascular disease. past surgical history: 1. cabg/avr in . 2. right femoropopliteal bypass graft . family history: a brother died of liver cancer at age 55. mother died of brain cancer at age 75. social history: the patient is married and lives with his wife. is a retired probation officer. he quit smoking cigarettes about eight years ago after a 100-pack-year history. he occasionally uses alcohol, no drug use. allergies: 1. intravenous contrast caused atn in . 2. oxacillin caused a rash. 3. iron/niacin caused a rash. 4. percocet and darvocet caused unknown reaction;
