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: past medical history: this patient has a past medical history significant for hypertension, hypercholesterolemia, diverticulosis, benign prostatic hypertrophy, achilles tendinitis. social history: he is a former smoker who quit 26 years ago. medications preoperatively: his medications preoperatively included aspirin 81 mg po qd, flomax 0.4 mg po qd and a multivitamin. allergies: his allergies include penicillin. medications on transfer: his medications on transfer to the hospital included lipitor 20 mg po qd, lopressor 25 mg po bid, colace prn and nitropaste q6h prn. hospital course: this is a 75 year old man who has no previous history of cardiac disease who presented to an outside hospital after experiencing two to three days of chest pain. he was then transferred to on for cardiac catheterization which revealed an 80-90 percent ostial left main disease, 80- 90 percent right coronary artery disease and an ejection fraction of 60 percent. an intraaortic balloon pump was placed in the cath lab following the procedure and he was subsequently referred for coronary artery bypass grafting. he underwent coronary artery bypass grafting times three on with the left internal mammary artery to the left anterior descending artery, saphenous vein graft to the obtuse marginal artery and saphenous vein graft to the right coronary artery as well as a right coronary artery endarterectomy. total cardiopulmonary bypass time was 65 minutes. total cross clamp time was 57 minutes. the patient was transferred from the operating suite to the cardiac surgery recovery unit in stable condition on iv nitroglycerin and propofol. the patient was extubated without event on postoperative day 1 in the morning with the patient's intraaortic balloon pump still at 1:1. he was eventually weaned off the intraaortic balloon pump which was discontinued on at which time he was started on lasix and lopressor with a good urine output. the patient continued to complain of incisional pain which was treated with percocet and morphine for breakthrough pain; however, remaining hemodynamically stable in sinus rhythm. the patient continued to advance his diet tolerating po's well with his foley catheter being discontinued on postoperative day 2. he was transferred from the cardiac surgery recovery unit to the floor on postoperative day 3 in stable condition; however, still somewhat slow to ambulate. the patient was reportedly feeling well. however, he complained of his inability to sleep due to his difficulty breathing at night. the patient had a pulmonary consult on at which time they recommended that due to his sleep apnea, he would benefit from using cpap on the floor overnight. however, without the patient having a sleep study or continuous o2 monitoring, they felt that this cpap may not benefit him since it could not be titrated. therefore, the patient was recommended to go home with supplemental oxygen once his volume status was optimized. the patient continued to progress well on the floor. however, he started to develop mild sternal drainage on for which he was started on vancomycin with a low grade temperature of 99 and a white count of 10. his sternal drainage subsided and he was felt ready to be discharged home with services. he was discharged in stable condition. on physical examination, he was neurologically awake and alert times three. his heart was regular rate and rhythm with no murmurs or rubs. from a respiratory status, he had decreased breath sounds in his left base. he had positive bowel sounds, tolerating a regular diet. his sternum was stable with only mild serosanguinous drainage from the distal 2-3 cm of his sternum. his right lower extremity vein harvest site was clean, dry and intact. he was afebrile with a blood pressure of 122/66 and normal sinus rhythm at 81 beats per minute, sating at 96 percent on room air with a white count of 10.9. discharge medications: lasix 20 mg po qd for seven days, potassium chloride 20 meq po qd for seven days, colace 100 mg po bid prn, ranitidine 150 mg po bid, percocet one to two tablets po q4h prn pain, plavix 75 mg po qd, lipitor 20 mg po qd, tamsulosin 0.4 mg po qhs, metoprolol 50 mg po bid, clindamycin 300 mg po q8h for five days and aspirin 325 mg po qd. discharge instructions: the patient was given follow-up instructions to follow up with the np or week to follow up on his sternal drainage. he was to follow up with dr. in one to two weeks and dr. in one to two weeks as well as dr. in four weeks. discharge diagnosis: the patient was discharged home in stable condition with a discharge diagnosis of coronary artery disease status post coronary artery bypass grafting. , procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery coronary arteriography using two catheters (aorto)coronary bypass of two coronary arteries angiocardiography of left heart structures left heart cardiac catheterization diagnostic ultrasound of heart implant of pulsation balloon nonoperative removal of heart assist system diagnoses: subendocardial infarction, initial episode of care coronary atherosclerosis of native coronary artery pure hypercholesterolemia unspecified essential hypertension hypertrophy (benign) of prostate without urinary obstruction and other lower urinary tract symptom (luts) unspecified sleep apnea diverticulosis of colon (without mention of hemorrhage) 

Answer: The patient is high likely exposed to
