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: this is a 74-year-old male from referred to dr. for cardiac consultation. the patient denied any history of myocardial infarction or prior cardiac catheterizations. he stated that for several years he has had on and off mild chest discomfort or aching in his chest that seemed to occur with exertion. the patient had ett done in which revealed 1.0-1.5 mm st segment depression in leads v5 and v6. cardiac catheterization revealed significant coronary artery disease. past medical history: mitral valve prolapse. depression. hiatal hernia. history of bronchitis. past surgical history: cholecystectomy. hernia repair. tonsillectomy. medications: aspirin 81 mg q.d., tylenol 50 mg q.d., ................. 1000 mg q.d., lescol 40 mg q.d., norvasc 5 mg q.d., amitriptyline 10 mg q.h.s. physical examination: vital signs: the patient was afebrile. vitals signs stable. lungs: clear to auscultation bilaterally. heart: regular, rate and rhythm. abdomen: benign scar. soft, nontender, nondistended. extremities: no edema. no varicosities. laboratory data: on admission sodium was 141, potassium 4.1, chloride 100, bicarb 31, bun 12, creatinine 0.8, glucose 120; white count 8.1, hematocrit 42.8. hospital course: the patient went to the operating room on , for coronary artery bypass grafting times four. the lima went to the left anterior descending, and the saphenous vein graft went to om1, diagonal 1, posterior descending artery. the patient was transferred to the intensive care unit and rapidly extubated. he was atrial paced with bradycardia. his neo-synephrine drip was appropriately weaned on postoperative day #1. on postoperative day #2, he was tolerating p.o. intake well, and he was transferred to the floor. bypass times from his surgery was 77 min, xt was 67 min. on postoperative day #2, his mediastinal and pleural tubes were removed. a .................. chest x-ray revealed no pneumothorax. on postoperative day #3, his atrial and ventricular wires were removed, and the patient was in normal sinus rhythm. his foley catheter was also removed. on postoperative day #4, the patient achieved level iv activity. his central venous line was also discontinued. on exam his sternum was stable and revealed no drainage, and his saphenous vein graft sites were clean, dry, and intact. discharge laboratory data: white count 10.3, hematocrit 26.4, platelet count 270; sodium 135, potassium 4.9, chloride 99, bicarb 30, bun 13, creatinine 0.6, glucose 128. condition on discharge: stable. discharge medications: lopressor 25 mg b.i.d., lasix 20 mg b.i.d. x 7 days, kcl 20 mg x 7 days, colace 100 mg b.i.d., ecotrin aspirin 325 mg q.d., lipitor 20 mg q.d., tylenol #3 tab p.o. q.4-6 hours p.r.n. discharge status: home. follow-up: the patient will follow-up with his primary care physician and cardiologist in three weeks. he will be followed by dr. in four weeks. discharge instructions: no driving for one month. no lifting of greater than 10 lbs for approximately six weeks. discharge diagnosis: status post coronary artery bypass grafting times four. , 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 intraoperative cardiac pacemaker diagnostic ultrasound of heart other esophagoscopy diagnoses: coronary atherosclerosis of native coronary artery intermediate coronary syndrome pure hypercholesterolemia unspecified essential hypertension mitral valve insufficiency and aortic valve insufficiency other specified cardiac dysrhythmias 

Answer: The patient is high likely exposed to
