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: mr. is a 64-year-old male who was admitted to the cardiology service on with an episode of chest pain. his workup revealed that he had severe reversible perfusion defects in his lateral and inferolateral walls on perfusion studies. they also found that he had an ejection fraction of 46%. the patient complains of symptoms of neck pain radiating to the chest and back for the last four months. his pain is associated with significant gas and would last approximately one to five minutes. it would come on with meals, exertion, rest, and more recently he has woken him from sleep. his pain would also resolve with resting, burping, and passing flatus. he typically has diaphoresis with his pain but rarely becomes nauseated. he has not had any vomiting. he reports that his pain has become more frequent occurring anywhere from one to five times per day. of note, he also sleeps on two pillows at night but denies having any paroxysmal nocturnal dyspnea. past medical history: 1. renal cell carcinoma, now status post left nephrectomy. 2. chronic obstructive pulmonary disease. 3. ? hyperlipidemia. he denies having any history of diabetes or hypertension, prior myocardial infarction or coronary artery disease. past surgical history: past surgical history was notable only for an appendectomy and a hernia repair. social history: he is married and lives with his wife. has smoked half a pack of cigarettes per day for the last 40 years. medications on admission: 1. enteric-coated aspirin. 2. ativan 1 mg p.o. b.i.d. physical examination on presentation: on physical examination his pulse was 59, his blood pressure was 146/83, he was saturating 96% on room air. his neck was without jugular venous distention. there was no bruits. his lungs were clear to auscultation. his heart had a regular rate and rhythm without murmurs, rubs or gallops. the abdomen was soft and nontender with normal active bowel sounds. extremities revealed he had 1+ dorsalis pedis and posterior tibialis pulses bilaterally. pertinent laboratory data on presentation: on laboratory studies, his baseline blood urea nitrogen 23 and creatinine was 1.4. his white blood cell count on admission was 8. his hematocrit was 40. his inr was 1.3, and his liver function tests were normal. hospital course: the patient was admitted to the cardiology service and had a cardiac catheterization. he was started on intravenous nitroglycerin which appeared to have been continued up until the time of operation. following his catheterization, his renal function was stable with no resultant increase in his creatinine. preoperatively he was started on lipitor. prior to his operation, he had an episode of chest pain while in the hospital. for this reason, he was started on intravenous heparin, and his intravenous nitroglycerin was continued. while he was waiting for his operation he also had three to four episodes of polymorphic nonsustained ventricular tachycardia at the rate of 150 to 180. this was while he was experiencing chest pain. he was loaded with magnesium, and his nitroglycerin was titrated. on , the patient was taken to the operating room where he had a coronary artery bypass graft times two. vessels grafted were left internal mammary artery to diagonal and saphenous vein graft to obtuse marginal. total cardiopulmonary bypass time was 54 minutes. cross-clamp time was 29 minutes. the patient's procedure itself was unremarkable. he was taken intubated to the cardiothoracic intensive care unit on a nitroglycerin and propofol drips. later that evening, he was extubated, and the following morning his chest tube was discontinued. he was transferred to the hospital floor. there, he had a temperature of 101.2 on the evening of the first postoperative day. a sputum sample was sent that grew both oropharyngeal flora and gram-negative rods suggesting hemophilus influenza. he was started on oral levaquin. during his postoperative recovery, on day two, he had an episode of rapid atrial fibrillation to 190 beats per minute. during this time he was mentating correctly and sustained his blood pressure. this broke spontaneously after approximately two minutes with no intervention. he was loaded with both calcium and magnesium for marginally low levels and given an extra dose of lopressor. the next day his lopressor was subsequently increased. he had no further episodes of atrial fibrillation for the remainder of his hospitalization. by the fourth postoperative day, the patient was eating, ambulating, and voiding. he was afebrile and felt well enough to be discharged home. in addition, the physical therapy staff ambulated with him and felt that he was safe to be discharged. discharge status: on the patient was discharged to home in the care of his family. condition at discharge: in stable condition. discharge followup: he was instructed to follow up with his primary care physician, . , in two weeks and with dr. in six weeks. medications on discharge: (the patient was discharged to home on the following medications) 1. levaquin 500 mg p.o. q.d. (times seven days). 2. lopressor 50 mg p.o. b.i.d. 3. aspirin 325 mg p.o. q.d. 4. lipitor 10 mg p.o. q.d. 5. colace 100 mg p.o. b.i.d. 6. lasix 20 mg p.o. b.i.d. (times seven days). 7. potassium chloride 20 meq p.o. b.i.d. (times seven days). 8. percocet one to two tablets p.o. q.4-6h. p.r.n. discharge diagnoses: 1. coronary artery disease; now status post coronary artery bypass graft times two. 2. nonsustained ventricular tachycardia. 3. nonsustained rapid atrial fibrillation. , m.d. dictated by: medquist36 procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery combined right and left heart cardiac catheterization coronary arteriography using two catheters diagnostic ultrasound of heart (aorto)coronary bypass of one coronary artery percutaneous [endoscopic] gastrojejunostomy diagnoses: coronary atherosclerosis of native coronary artery intermediate coronary syndrome chronic airway obstruction, not elsewhere classified cardiac complications, not elsewhere classified atrial fibrillation peripheral vascular disease, unspecified surgical operation with anastomosis, bypass, or graft, with natural or artificial tissues used as implant causing abnormal patient reaction, or later complication, without mention of misadventure at time of operation personal history of malignant neoplasm of kidney acquired absence of kidney
