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: the patient is a 63 year old male who has been experiencing fatigue, dyspnea and left-sided chest tightness with exertion over the past two years. over the past eight months prior to admission, he has been more aware of the exertional symptoms. he recently was having increased chest tightness and neck pain any time that he walked at a risk pace. he also has been having episodes of paroxysmal nocturnal dyspnea and night sweating over the past year as well as two syncopal episodes this past summer, although they were thought to be related to hypoglycemia as his sugar was found to be less than 20 mg/dl. he has had episodes of lightheadedness as well as lower extremity edema. he denied any claudication or orthopnea. the patient was referred for a stress test in . he exercised for ten minutes on a protocol. he had chest pain and 3 to 3. depressions in the inferior lateral leads. echocardiogram revealed an ejection fraction of 41% with mild hypokinesis. cardiac catheterization done on showed three vessel coronary artery disease, normal left ventricular systolic function. he had 60 to 70% stenosis of the left anterior descending, 95% stenosis of the left circumflex. of note is that at the end of the cardiac catheterization procedure he experienced ventricular fibrillation which was promptly reversed without further episodes. as a result of the catheterization, the patient was referred for a cardiac bypass procedure. past medical history: 1. gastroesophageal reflux disease; 2. mumps at the age of 22, resulting in decreased pituitary function; 3. insulin dependent diabetes mellitus; 4. testosterone replacement requirement; 5. proteinuria; 6. lung tumor removed three years ago;

testosterone patch 10 mg p.o. q. day; prilosec 40 mg p.o. q. day; lantus 24 units q.h.s.; humalog subcutaneously; aspirin 325 mg q. day; toprol xl 25 mg p.o. q. day. laboratory data: hematocrit 34.7, white blood cell count 16.6, platelets 180. urinalysis, negative. glucose 330, creatinine 1.4, bun 34, potassium 4.5, chloride 100. alt 14, ast 14, total bilirubin 0.5, alkaline phosphatase 79. hospital course: the patient was admitted to the cardiac surgery service for a surgical intervention. on , the patient underwent coronary artery bypass grafting times four with left internal mammary artery to the left anterior descending coronary artery, saphenous vein graft to diagonal branch, saphenous vein graft to obtuse marginal branch and saphenous vein graft to the posterior lateral branch of the right coronary artery. the procedure was without complications, please see the full operative report for details. the patient was in stable condition. the patient was transferred to the cardiac intensive care unit for initial management. the patient remained intubated. the patient was gradually weaned off the ventilator as tolerated. the patient was extubated on postoperative day #1 requiring continuous neosynephrine requirement which was weaned gradually. the patient's vital signs remained stable. his electrolytes were repleted as needed. the patient remained in regular rhythm, although slightly tachycardiac. on postoperative day #2, the patient was transferred to the regular floor in stable condition. the patient continued to do very well. his chest tubes were removed on postoperative day #2. his urine catheter was removed on postoperative day #2 as well. diabetes consult saw the patient and evaluated his current management of diabetes. the pacing wires were removed on postoperative day #3. the patient remained in sinus rhythm during his stay on the service. the patient was ambulating without difficulty and was cleared by the physical therapy. the patient was discharged on to home with services in stable condition. condition on discharge: good. discharge disposition: home with services. discharge diagnosis: 1. three vessel coronary artery disease, status post coronary artery bypass graft. 2. insulin dependent diabetes mellitus. 3. hypertension. discharge instructions: 1. the patient is to follow up with his surgeon, dr. in approximately four weeks. 2. the patient is to follow up with his cardiologist in approximately two to three weeks. 3. the patient is to follow up with his primary care physician in approximately one week. 4. the patient is to remain on plavix for approximately one month. discharge medications: 1. plavix 75 mg p.o. q. day times one month 2. lopressor 25 mg p.o. b.i.d. 3. insulin subcutaneously as per instructions 4. testosterone patch 5 mg, two patches t.d. q. 24 hours 5. protonix 40 mg p.o. q. day 6. colace 100 mg p.o. b.i.d. prn constipation 7. milk of magnesia 30 ml p.o. h.s. prn constipation 8. percocet one to two tablets p.o. q. 4-6 hours prn pain 9. aspirin 325 mg ec p.o. q. day 10. potassium chloride 20 meq p.o. q. 24 hours, times ten days 11. lasix 20 mg p.o. q. 12 hours times ten days , m.d. dictated by: medquist36 procedure: (aorto)coronary bypass of three coronary arteries single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery coronary arteriography using two catheters left heart cardiac catheterization other electric countershock of heart diagnoses: coronary atherosclerosis of native coronary artery esophageal reflux unspecified essential hypertension cardiac complications, not elsewhere classified other and unspecified angina pectoris ventricular fibrillation diabetes mellitus without mention of complication, type i [juvenile type], not stated as uncontrolled 

Answer: The patient is high likely exposed to
