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 73-year-old white male patient who is admitted to hospital on with an upper gastrointestinal bleed. endoscopy at that time revealed duodenal ulcer which was injected with epinephrine and he also had two avm's which were cauterized. h. pylori at that time was reportedly positive. while he was being treated at hospital in the intensive care unit, he experienced some vague abdominal pain which radiated to his chest and his neck and ultimately was found to have suffered an anteroseptal myocardial infarction. cardiac catheterization revealed a tight left main stenosis as well as three vessel coronary artery disease and he was transferred to on for coronary artery bypass graft. past medical history: significant for hypertension, hypercholesterolemia, coronary artery disease, status post remote myocardial infarction by electrocardiogram, positive claudication, peripheral vascular disease, gastroesophageal reflux disease, chronic obstructive pulmonary disease, syncope, history of prostate cancer, status post radiation treatments. he is a two pack a day smoker and question of a left carotid artery stenosis. the patient is widowed, retired and lives alone. medications: 1. losartan 50 mg p.o. q.d. 2. atorvastatin 10 mg p.o. q.d. 3. tiazac 300 mg p.o. q.d. 4. protonix 40 mg p.o. q.d. laboratory data: upon admission to the hospital were unremarkable as baseline serum creatinine was 1.3. he had a peak cpk of 454 as well as a peak troponin of 16.6. the patient was admitted with ekg st elevations in anterior leads. hospital course: he was admitted to the cardiology service and underwent a carotid artery ultrasound on , which revealed no evidence of carotid artery stenosis on the right or left and he also had his groin viewed by ultrasound which revealed no evidence of pseudoaneurysm or av fistula on either groin. gastroenterology medicine consultation was obtained at that time and it was their recommendation to do a repeat upper gastrointestinal endoscopy prior to coronary artery bypass graft. the patient also had a pulmonary medicine consultation on , due to a longstanding diagnosis of chronic obstructive pulmonary disease. their recommendation was for the patient to have pulmonary function test with bronchodilators as well. the patient did not undergo an upper gastrointestinal endoscopy because of his tenuous cardiac status and no evidence of rebleeding. his pulmonary function tests revealed likely early chronic obstructive pulmonary disease, but normal spirometry and volumes were measured at that time. the patient was taken to the operating room on , where he underwent coronary artery bypass graft times 3 with a lima to the lad, saphenous vein to the om and saphenous vein to the pda by dr. . postoperatively, the patient was transported from the operating room to the cardiac surgery recovery unit in good condition on iv propofol drip. he was weaned from mechanical ventilator and extubated the night of surgery. on postoperative day 1, he remained on an insulin drip and was continued to be followed by gi medicine service who ultimately signed off with their recommendations for h. pylori treatment. the patient was begun with cardiac rehabilitation and physical therapy. over the next couple of days, he was transferred out of the intensive care unit to the telemetry floor on postoperative day 1. the patient continued to progress from a cardiac rehabilitation and mobility stand point. he had remained hemodynamically stable and was weaning down oxygen support and progressing well with pulmonary toilet and on postoperative day 4, the patient went into rapid atrial fibrillation with a ventricular response in the 140's to 150's. he was treated with beta-blockers and amiodarone. an electrophysiology consult was obtained at that time and it was their recommendation to continue with the beta-blockers and amiodarone as well as to replace electrolytes. the patient then was noted to have a small amount of serous sternal drainage at the distal pole of his wound over the next two days or so, but this subsided without any intervention. the patient remained in the hospital for the next few days due to a rising creatinine. his lasix was discontinued as his creatinine was noted to rise. it peaked at 1.8 on and has come down to 1.7 today on . he is ready to be discharged home today with visiting nurses to monitor his wound as well as vital signs. discharge condition: the patient is afebrile. he is in sinus rhythm with a rate of about 60 to 65 per minute. his blood pressure is 96/49 this morning. his lopressor had been decreased from 50 mg b.i.d. to 25 mg b.i.d. upon discharge and his amiodarone had also been decreased from 200 three times a day to 200 mg twice a day due to some bradycardia over the past couple of days with a low rate of about 50. he is presently at a rate of 60. neurologically, the patient is grossly intact. pulmonary exam reveals the lungs are clear to auscultation bilaterally. his coronary exam is regular rate and rhythm. his abdomen is benign and his incisions are clean, dry and intact. discharge medications: 1. colace 100 mg p.o. b.i.d. 2. aspirin 325 mg p.o. q.d. 3. percocet 5/325 one p.o. q. 6 hours p.r.n. pain. 4. protonix 40 mg p.o. b.i.d. until and then decrease to q.day. 5. clarithromycin 500 mg p.o. q. 12 hours times 6 more days. 6. amoxicillin 1 gram p.o. q. 12 hours times 6 more days. 7. atorvastatin 10 mg p.o. q.d. 8. lopressor 25 mg p.o. b.i.d. 9. amiodarone 200 mg po. b.i.d times one month. this was at the recommendation of the electrophysiology service at the time he went into atrial fibrillation or this can be modified at the discretion of the patient's primary cardiologist, dr, . condition on discharge: good. the patient is discharged home. he is to follow up with dr. at cardiac surgery in six week. he is also to follow up with the patient's primary cardiologist, dr. in approximately two weeks as well as his primary care physician, . in two weeks as well. discharge diagnosis: 1. coronary artery disease, status post coronary artery bypass graft. 2. chronic obstructive pulmonary disease. 3. gastroesophageal reflux disease. 4. postoperative atrial fibrillation. 5. positive h. pylori. discharge condition: good. , procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery (aorto)coronary bypass of two coronary arteries diagnoses: coronary atherosclerosis of native coronary artery pure hypercholesterolemia unspecified essential hypertension acute myocardial infarction of other anterior wall, initial episode of care chronic airway obstruction, not elsewhere classified
