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 65-year-old male patient who initially presented with back pain. upon work-up for that was found to have an abdominal aortic aneurysm which has been followed in recent months by echocardiography. in the aneurysm was noted to have expanded and upon work-up for abdominal aortic aneurysm resection, was found to have a positive exercise tolerance test. mr. was then referred to cardiac catheterization which revealed two vessel coronary artery disease with a left ventricular ejection fraction of 40%. past medical history: abdominal aortic aneurysm as previously noted with surgical resection pending, hypertension, arthritis, copd, status post cva years ago with no residual. medications: toprol 200 mg po q d, norvasc 10 mg po q d, ativan 0.5 mg prn, aspirin 325 mg po q d. allergies: the patient states no known drug allergies. social history: the patient is a smoker who continues to smoke ?????? pack of cigarettes per day. physical examination: upon admission revealed vital signs within normal limits and an unremarkable physical examination. hospital course: the patient was admitted to the hospital on the day of surgery, , was taken to the operating room where he underwent coronary artery bypass graft times three with a lima to the lad, a vein to the om and a vein to the diagonal. postoperatively the patient was on dobutamine, propofol iv drip and was atrially paced. he was transported from the operating room to the cardiac surgery recovery unit. postoperative day #1 the patient had been weaned off his vasoactive drip, his pulmonary artery catheter was discontinued, he had been weaned from mechanical ventilator and extubated, his chest tubes were discontinued, the patient was started on diuretic and beta blocker and was transferred out of the intensive care unit to the telemetry floor. early the following day on postoperative day #2 the patient was noted to be in rapid atrial fibrillation for which he was started on iv amiodarone as well as an increase in his lopressor dose was initiated. the patient was also noted on postoperative day #1 by routine chest x-ray which was obtained after the chest tubes were discontinued, he was noted to have bilateral apical pneumothoraces. the patient did receive bilateral chest tubes for this and was followed with subsequent chest x-rays which showed resolution in the pneumothoraces. after approximately 48 hours with the chest tubes in, the right pleural tube was discontinued with no sequella, the left, however, continued to have a small air leak and was left in for an additional 24 hours. this was ultimately discontinued on . on postoperative day #5, a follow-up chest x-ray had subsequently revealed no pneumothoraces and was essentially a normal x-ray. the patient had been started on anticoagulation due to multiple bouts of postoperative atrial fibrillation and was begun on coumadin. on postoperative day #6, , the patient remained hemodynamically stable, his oxygenation was adequate on room air, he was approximately at his preoperative weight and remained in atrial fibrillation with a controlled ventricular response and adequate blood pressure. it was felt that he had remained stable for a significant period of time and was ready to be discharged home. condition on discharge: temperature 98, blood pressure 119/58, respiratory rate 20. his weight on the day of discharge 103.2 kg which is essentially the same as his preoperative weight of 103 kg. most recent laboratory values, white blood cell count of 11.5, hematocrit 23.5 which was down slightly from his previous hematocrit of 25, although the patient was asymptomatic. with this hematocrit it was felt appropriate to discharge him and start him on iron. other laboratory values revealed a pt of 12.4 with inr of 1.1, bun 24, creatinine 1.0. on physical examination, neurologically the patient is alert and oriented with a steady gait. his cardiac exam was unremarkable while irregular with no murmur and no gallop. sternum is stable, incisions clean, dry and intact with steri-strips. his lungs are clear to auscultation. there was a tiny amount of subcu emphysema anteriorly from the 4th to 8th intercostal space. room air oxygen saturation was 96%. his abdomen was soft, obese with positive bowel sounds in all four quadrants with a palpable abdominal aortic aneurysm noted. his legs were warm, well perfused, with palpable pulses in his feet. his incision to his right leg is clean, dry with steri-strips intact and minimal edema. discharge medications: coumadin 5 mg upon the day of discharge. pt inr is to be followed by clinic and dr. office with pt, inr scheduled for with the results to be called to dr. office, to continue his coumadin dosing for his atrial fibrillation. other discharge medications, amiodarone 400 mg po tid until , then it should be decreased to 400 mg po bid times 7 days, then 200 mg q d as a maintenance dose until discontinued by primary care physician or cardiologist, lopressor 75 mg po bid, lasix 20 mg po bid times 7 days, potassium chloride 20 meq po bid times 7 days, zantac 150 mg po bid, dilaudid 2 mg po q 4-6 hours prn pain, aspirin 81 mg po q d, niferex 150 mg po q d, colace 100 mg po bid. the patient is to follow-up with dr. as previously noted for his coumadin dosing. the patient is to follow-up with dr. in 6 weeks for postoperative check. , m.d. dictated by: medquist36 procedure: insertion of intercostal catheter for drainage insertion of intercostal catheter for drainage single internal
