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 74-year-old male with chest pain on exertion since . the symptoms resolved with rest. during work-up he had had an echo which had shown normal left ventricular motion. it also showed moderate aortic stenosis with a peak gradient of 32 and an aortic valve area of 1 cm sq. he also had trace mitral regurg. he presents for cardiac catheterization which was significant for left main stenosis 70%, and lad of 70%, circumflex of 90%, right coronary artery 50%, diagonal 80% and ramus 80%. he had aortic gradient of 20. the patient was then evaluated for cardiothoracic surgery by the cardiothoracic surgery service for avr bypass. past medical history: significant for hypertension, hypercholesterolemia and benign prostatic hypertrophy. past surgical history: significant for hernia repair in . medications: include diovan 12.5 mg po q, lipitor 10 mg po q d, hytrin 5 mg po q d, asa 81 mg po q d, multivitamin once per day. allergies: no known drug allergies. social history: the patient is retired, sailing in the caribbean. review of systems: the patient has significant hearing loss and uses hearing aids. physical examination: the patient's heart rate is 68, blood pressure 130/60. heent: within normal limits. neck shows no bruits. chest, clear to auscultation. heart, regular rate and rhythm. no systolic ejection murmur. abdomen soft, nontender, no masses. extremities, no edema, distal pulses are intact. laboratory data: included white count of 6.5, hematocrit 39.3, platelet count 273,000, sodium 136, potassium 4.1, chloride 100, co2 29, bun 23, creatinine 1, glucose 104. hospital course: the patient returned after cardiac catheterization, returned to and on the day of admission went to the operating room and underwent coronary artery bypass graft times three with a lima to lad, svg to ramus, svg to diagonal. also underwent an avr with a 25 mm pericardial valve. the patient tolerated the procedure well, was taken to the intensive care unit on no drips. upon getting to the intensive care unit, he had labile systolic blood pressure, was placed on a nipride drip which was weaned. he received one unit of packed red blood cells. he was weaned from ventilatory support and extubated without problem. remained stable on the first postoperative night. postoperative day #1 the patient was started on po lopressor, lasix and aspirin. continued with pulmonary toilet. his diet was advanced. he was transferred to the floor in stable condition on postoperative day #2. the patient's chest tubes were removed. the patient was receiving physical therapy. on postoperative day #3 the pacing wires were removed, the drain in the right vein harvest site was removed as well. lopressor was increased for better blood pressure control. on admission he was started on captopril 6.25 mg po tid. on postoperative day #4 and #5 the patient remained stable, had been working with physical therapy and was ready for discharge home with home physical therapy. discharge diagnosis: 1. coronary artery disease, status post cabg times three. 2. aortic stenosis status post avr. 3. hypertension. 4. hypercholesterolemia. 5. benign prostatic hypertrophy. discharge medications: hytrin 5 mg po q d, lasix 20 mg po bid times 7 days, kcl 20 meq po bid times 7 days, colace 100 mg po bid, enteric coated aspirin 325 mg po q d, lipitor 10 mg po q d, lopressor 75 mg po bid, captopril 6.25 mg po tid, percocet 5/325 po q 4 hours prn. condition on discharge: stable. fop: patient to follow-up with dr. in 4 weeks. patient to follow-up with pcp, . in 2 weeks. , m.d. dictated by: medquist36 procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery (aorto)coronary bypass of two coronary arteries open and other replacement of aortic valve diagnoses: coronary atherosclerosis of native coronary artery pure hypercholesterolemia unspecified essential hypertension aortic valve disorders other and unspecified angina pectoris 

Answer: The patient is high likely exposed to
