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 69-year-old obese white male with a history of chronic obstructive pulmonary disease who, in of this year, was found to have an abdominal aortic aneurysm measured at 5.9 cm. the patient presents for an elective abdominal aortic aneurysm repair. the incidental finding was during a cardiac angiography done at hospital. the patient denies any claudication, rest pain, abdominal pain, or back pain. past medical history: (past medical history is significant for) 1. chronic obstructive pulmonary disease. 2. coronary artery disease. past surgical history: past surgical history is significant for an umbilical hernia repair in and a right inguinal hernia repair. medications on admission: none. allergies: no known drug allergies. physical examination on presentation: the patient was obese, in no acute distress. vital signs were stable. the chest was clear to auscultation bilaterally. the heart was regular. the abdomen was soft and nontender. there was a small palpable hernia lateral to the umbilicus which was reducible. there was no expansile mass. bilaterally, distal pulses were intact. pertinent laboratory data on presentation: preoperative laboratories were significant for a hematocrit of 50. inr was 1.1. blood urea nitrogen was 17, and creatinine was 1.1. pertinent radiology/imaging: preoperative imaging included an angiography which showed a severely angulated abdominal aorta with aneurysmal dilatation of the infrarenal aorta. preoperative electrocardiogram revealed sinus with a left shift. hospital course: on the day of admission, the patient went to the operating room and underwent an open abdominal aortic aneurysmal repair and incisional hernia repair. the patient tolerated the procedure well and was extubated postoperatively and transferred to the vascular intensive care unit after an uneventful recovery in the postanesthesia care unit. the patient remained hemodynamically stable during the postoperative period requiring no pressor support. the patient was maintained on an epidural for the first three postoperative days with adequate pain control and was transitioned to subcutaneous and oral pain regimens. the patient's wound remained clean, dry, and intact. he completed a course of perioperative antibiotics. the patient's distal pulses remained intact, and the patient was evaluated by physical therapy and was ambulating without difficulty at the time of discharge. on postoperative day four, the patient's diet was advanced, and the patient has since had flatus and a bowel movement. the patient's laboratory values were significant for a drop in his platelet count, and a heparin-associated thrombocytopenic antibody was sent which was still pending. the patient had been off of heparin since then, and his platelet count has since stabilized. discharge disposition: the patient was stable and ready for discharge to home. discharge diagnoses: 1. abdominal aortic aneurysm; now status post repair. 2. coronary artery disease. 3. chronic obstructive pulmonary disease. medications on discharge: (medications on discharge included) 1. tylenol no. 3 one to two tablets p.o. q.4h. as needed. 2. colace 100 mg p.o. twice per day times two weeks and as needed thereafter. discharge instructions/followup: the patient was to follow up with dr. in 7 to 10 days for staple removal. condition at discharge: condition on discharge was stable. , m.d. dictated by: medquist36 procedure: resection of vessel with replacement, aorta, abdominal incisional hernia repair diagnoses: coronary atherosclerosis of native coronary artery incisional hernia without mention of obstruction or gangrene other emphysema abdominal aneurysm without mention of rupture 

Answer: The patient is high likely exposed to
