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: past medical history: as indicated above. past surgical history: status post cabg years ago. allergies: the patient has no known drug allergies. at-home medications: 1. cartia xl 360. 2. persantine 50 t.i.d. 3. zestril 60 q.d. 4. hydralazine 50 three times a day. 5. aspirin 325 once a day. 6. atenolol 100 once a day. 7. protonix 40 once a day. 8. hydrochlorothiazide 25 once a day. 9. lipitor 20 a day. 10. nph 24, humalog 5 units in the morning, nph 27 in the evening, humalog 6 units in the evening. 11. glucophage 1,000 b.i.d. hospital course: the patient was admitted to the cardiology medical service for workup of symptoms of acute myocardial infarction. on workup, he received an echocardiogram which showed an ef of 70% and he was taken to the catheterization laboratory which showed severe three vessel disease. he was then taken to the operating room on for an emergent coronary artery bypass operation. this was a three vessel cabg redo with vein graft to lad, ramus, and pda. the pump time was 73 minutes and cross clamp time was 62 minutes and he tolerated the procedure well. he was transferred to the csru in stable condition, intubated. in the csru, he did well and essentially started to be diuresed and was put on lopressor for blood pressure control. he was successfully transferred to the floor on . his recovery course was essentially unremarkable. the blood pressure was well controlled. his blood sugar was also well controlled. he was seen by physical therapy who cleared him for level v activity and he is discharged to home on . discharge medications: the patient was instructed to restart his home medication except persantine and plavix. the blood pressure control has been effective with his home medications, antihypertensive medication regimen, and lasix 40 t.i.d. and a prescription for lasix and potassium was given to him at the time of discharge and also dilaudid for pain medication, and colace for constipation as needed. discharge instructions: the patient is instructed to call his cardiologist for follow-up within the next two weeks for antihypertensive medication adjustment and he was also instructed to call dr. office for surgical postoperative follow-up. disposition: the patient was discharged to home in stable condition. discharge diagnosis: coronary artery disease, status post coronary artery bypass graft re-do. , m.d. dictated by: medquist36 procedure: (aorto)coronary bypass of three coronary arteries extracorporeal circulation auxiliary to open heart surgery coronary arteriography using two catheters left heart cardiac catheterization aortography diagnoses: subendocardial infarction, initial episode of care coronary atherosclerosis of native coronary artery pure hypercholesterolemia congestive heart failure, unspecified unspecified essential hypertension coronary atherosclerosis of autologous vein bypass graft personal history of tobacco use unspecified disorder of kidney and ureter coronary atherosclerosis of artery bypass graft
