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 59-year-old male who had non-q-wave myocardial infarction on treated with ptca stent to mlad, dlad, and prca and mrca. the patient underwent a follow-up study in which showed apical and septal ischemia. cardiac catheterization showed isr treated by ptca/brachy therapy of mid and distal left anterior descending stents, prca stent and ptca stent to prca. the patient presented with recurrent exertional chest tightness for the past three weeks. past medical history: hypertension. hypercholesterolemia. anxiety disorder. coronary artery disease. status post multiple ptca and stent placement. medications on admission: altace 10 mg p.o. q.d., lopressor 12.5 p.o. b.i.d., klonopin 1 q.d., lipitor 20 q.d., .................., aspirin, fish oil, prozac 40 mg p.o. q.d., trazodone 1 tab p.o. q.h.s., plavix 75 mg p.o. q.d., imdur 30 mg p.o. q.d. allergies: no known drug allergies. physical examination: general: the patient was a well-developed, well-nourished male in no apparent distress. heent: cranial nerves ii-xii intact. no evidence of scleral icterus. moist mucous membranes. no evidence of oral ulcers. chest: clear to auscultation bilaterally. sternal incision site with no evidence of erythema, with good healing. cardiovascular: regular, rate and rhythm. no1 murmurs. abdomen: soft, nontender, nondistended. no evidence of guarding or rebound. laboratory data: cbc on , was with a white count of 7.2, hematocrit 27, platelet count 257. hospital course: the patient is a 59-year-old male status post non-q-wave myocardial infarction in with history of multiple ptca and stents presenting with recurrence of exertional chest tightness times three weeks. the patient underwent an uncomplicated coronary artery bypass grafting times four (lima to left anterior descending, saphenous vein graft to distal right coronary artery, saphenous vein graft to posterolateral om, sequential). postoperatively the patient was taken to the csru for close observation. after being extubated, the patient maintained good oxygenation on 2 l nasal cannula which was ultimately weaned off. by postoperative day #3, chest tube, foley and pacing wires were all removed. at this time, the patient was transferred to the floor at which point the patient was tolerating a regular diet, making good urine output, and maintaining good pressure with good oxygen saturation. because the patient achieved level 5 physical therapy goal which involves being able to climb stairs, the decision was made to discharge the patient on postoperative day #5 in good condition. condition on discharge: good. discharge status: to home. discharge diagnosis: status post coronary artery bypass grafting times four. discharge medications: prozac 40 mg p.o. q.d., trazodone 25 mg p.o. q.h.s. p.r.n. insomnia, clopidogrel 75 mg p.o. q.d., oxazepam 15-30 mg p.o. q.h.s. p.r.n. insomnia, milk of magnesia 30 cc p.o. q.h.s. p.r.n. constipation, percocet tab p.o. q.4 hours p.r.n. pain, aspirin 325 mg p.o. q.d., ranitidine 150 mg p.o. b.i.d., colace 100 mg p.o. b.i.d., furosemide 40 mg p.o. b.i.d., potassium 20 meq p.o. b.i.d., metoprolol 25 mg p.o. b.i.d. follow-up: the patient was instructed to follow-up with dr. in days. the patient was also instructed to follow-up with dr. in 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 diagnostic ultrasound of heart aortography diagnoses: coronary atherosclerosis of native coronary artery intermediate coronary syndrome pure hypercholesterolemia unspecified essential hypertension percutaneous transluminal coronary angioplasty status anxiety state, unspecified old myocardial infarction 

Answer: The patient is high likely exposed to
