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: patient is a 78-year-old male with a history of chronic stable exertional angina with episodes several times per week. patient had positive st changes on ekg and a catheterization at outside hospital which showed left main and three-vessel disease. patient also at this time reported some symptoms of unstable angina. past medical history: 1. coronary artery disease. 2. hypertension. 3. hypercholesterolemia. 4. peripheral vascular disease. 5. prostate cancer. 6. osteoarthritis. past surgical history: 1. left carotid endarterectomy. 2. lumbar disc surgery. 3. knee surgery. medications on admission: 1. aspirin 325 mg p.o. q. day. 2. atenolol 25 mg p.o. q. day. 3. lipitor 10 mg p.o. q. day. 4. vasotec 10 mg p.o. q. day. 5. norvasc 5 mg p.o. q. day. 6. isosorbide dinitrate 2.5 mg p.o. q.i.d. 7. percocet, one to two tabs, p.o. q. 4 to 6 hours p.r.n. for pain. 8. nitro patch 0.5 tp p.r.n. for chest pain. allergies: patient has no known drug allergies. cardiac catheterization showed ejection fraction of 45%, 70% occlusion of the left main, 70% occlusion of the left anterior descending, 100% occlusion of the right coronary artery, and moderate mitral regurgitation. echocardiogram on showed left ventricular hypertrophy with moderately decreased left ventricular function, moderate mitral regurgitation, moderate tricuspid regurgitation. laboratory data on admission: patient had a white count of 6.7, hematocrit 34, platelets 186, sodium 140, potassium 4.2, chloride 107, bicarbonate 26, bun 18, creatinine 1.1, glucose 120, pt 12.9, inr 1.1, ptt 49.3 on heparin drip. physical examination: patient is awake, alert, and oriented times three. head is normocephalic, atraumatic; no scleral icterus noted. heart is regular rate and rhythm. chest is clear to auscultation bilaterally. abdomen is soft, nontender, nondistended; positive bowel sounds. extremities are warm and well perfused; no cyanosis or edema noted. patient has equal grip strength bilaterally. pulse exam is 2+ bilaterally throughout; no carotid bruits noted. summary of hospital course: patient is a 78-year-old male with history of hypertension, hypercholesterolemia, and chronic angina who underwent elective catheterization at outside hospital revealing significant three-vessel disease and an ekg which revealed st changes. patient was transferred to from outside hospital for further evaluation and treatment of cardiac disease. was placed on heparin drip 900 units an hour. cardiac surgery was consulted on and preoperative workup was initiated for coronary artery bypass graft surgery with dr. . on patient underwent carotid ultrasound which showed no significant stenosis in the right or left carotid arteries. preoperative echocardiogram displayed an ejection fraction of 30 to 35% with normal left atrium and mild dilatation of left ventricle. on patient was taken to the operating room for coronary artery bypass graft times three, more specifically, 1) left internal mammary artery graft to left anterior descending, 2) saphenous vein graft to descending right coronary artery, 3) saphenous vein graft to diagonal. in addition, closure of atrial septal defect. surgeon was dr. . assistants were dr. ................ and physician assistant . for more detail, please see operative reports. postoperatively, patient was taken to the cardiac surgery recovery unit where the patient was extubated at midnight following a day of surgery. on postop day number one swan ganz catheter was discontinued. in addition on postop day number one patient was transfused two units of blood for a hematocrit of 28. later on in postoperative day number one patient was transferred to the floor, where he did well. on postoperative day number two patient chest tube and pacing wires were discontinued, as well as the foley. patient was seen by physical therapy, who cleared him eventually for home. on postoperative day number three patient had no events, was feeling well, working with physical therapy. on postoperative day number four patient was physical therapy level 5 and deemed well enough to go home, where he has ample family support. disposition: to home with vna. discharge condition: good. discharge diagnoses: 1. coronary artery disease. 2. hypertension. 3. hypercholesterolemia. 4. peripheral vascular disease. discharge medications: 1. colace 100 mg p.o. b.i.d. 2. ranitidine 150 mg p.o. b.i.d. 3. aspirin 325 mg p.o. q. day. 4. plavix 75 mg p.o. q. day times three months. 5. percocet, one to two tabs, p.o. q. 4 to 6 hours p.r.n. for pain. 6. isosorbide mononitrate 30 mg p.o. q. day. 7. lasix 20 mg p.o. q. day times two weeks. 8. metoprolol 25 mg p.o. b.i.d. 9. potassium chloride 20 meq p.o. q. day times two weeks. die instructions: 1. patient is to follow up with the primary care physician in one to two weeks. please call for appointment. 2. follow up with cardiologist in one to two weeks. please call for appointment. 3. follow up with dr. in approximately one month. please call for appointment. , 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 other and unspecified repair of atrial septal defect transfusion of packed cells diagnoses: coronary atherosclerosis of native coronary artery intermediate coronary syndrome pure hypercholesterolemia mitral valve disorders unspecified essential hypertension ostium secundum type atrial septal defect diseases of tricuspid valve 

Answer: The patient is high likely exposed to
