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 44 year old male with known coronary artery disease status post inferior myocardial infarction and status post stenting of the right coronary artery in . the catheterization at that time also demonstrated multiple lesions of the left anterior descending and left circumflex. subsequently he was stable and underwent a second catheterization in because of more recurrent chest pain, which showed good result in the right coronary artery, no change in the left coronary artery lesion. since then he continued on a stable course until the past week when he developed progressive episodes of chest pain. the pain began to occur at rest and it was not relieved with nitroglycerin sublingual. he was promptly brought to . past medical history: 1. hypertension. 2. hypercholesterolemia. 3. decreased hdl. 4. coronary artery disease; myocardial infarction in 12/. past surgical history: 1. status post right coronary artery stenting in . 2. status post left ankle surgery. allergies: include vicodin and question of an intravenous antibiotics, unknown name. medications on admission: 1. aspirin 325 mg p.o. q. day. 2. toprol xl 100 mg p.o. q. day. 3. lisinopril 5 mg p.o. q. day. 4. lipitor 10 mg p.o. q. day. 5. multivitamin one p.o. q. day. 6. calcium supplement q. day. social history: the patient is married with three children, exercises on a regular basis. he is a past smoker who quit in . denies any etoh. physical examination: on admission, the patient has vital signs which are stable. heent is within normal limits. neck shows no lymphadenopathy, no bruits. chest is clear to auscultation. heart is regular rate and rhythm with no murmur. abdomen is soft, nontender. extremities with normal pulses; no edema. laboratory: on admission, white blood cell count of 6.0, hematocrit of 39, platelets of 216. sodium of 143, potassium of 4.5, bun of 14, creatinine of 1.2, glucose of 69, inr 1.0. ekg was significant for normal sinus rhythm with normal axis. no evidence of ischemia. hospital course: on the day of admission, the patient underwent cardiac catheterization. this revealed 90% stenosis of the right coronary artery, 70% stenosis of the proximal left anterior descending, mid-lad, and 70% stenosis of the diagonal 1, 70% stenosis of the proximal circumflex and 90% stenosis of the obtuse marginal 1. on hospital day two, the patient went to the operating room where he underwent coronary artery bypass graft times five. he had left internal mammary artery to the left anterior descending, saphenous vein graft to diagonal, saphenous vein graft ramus; saphenous vein graft to right coronary artery and left radial artery to the obtuse marginal. he tolerated this procedure well; was transferred to the intensive care unit, intubated and on a nitroglycerin drip. , m.d. dictated by: medquist36 procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery coronary arteriography using two catheters angiocardiography of left heart structures diagnostic ultrasound of heart (aorto)coronary bypass of four or more coronary arteries diagnoses: coronary atherosclerosis of native coronary artery intermediate coronary syndrome pure hypercholesterolemia unspecified essential hypertension personal history of tobacco use percutaneous transluminal coronary angioplasty status old myocardial infarction other complications due to other cardiac device, implant, and graft 

Answer: The patient is high likely exposed to
