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 an 83-year-old gentleman who was admitted on , presenting with acute respiratory distress and angina pain. he had a three year history of dyspnea on exertion, worse over the several weeks prior to admission with the addition of new onset anginal pain with exertion. his cardiac risk factors included smoking and a family history of coronary artery disease. at the time of his initial workup, the patient was noted to have electrocardiogram changes suggestive of ischemia as well as enzyme levels ruling him in for a myocardial infarction. the patient was subsequently admitted. medications on admission: aspirin 325 mg p.o. q.d. physical examination: on admission, the patient was afebrile with a blood pressure of 114/60, a pulse of 70, a respiratory rate of 12 and an oxygen saturation of 90% on room air. his jugular venous pressure was at 8 cm. he had bilateral crackles, right greater than left. his heart had a regular rate and rhythm. he had a iv/vi systolic ejection murmur at the left upper sternal border that radiated to his carotids. his abdomen was soft, nontender and nondistended with normal active bowel sounds. his extremities were warm and well perfused. hospital course: as the patient ruled in for an acute myocardial infarction by enzyme and electrocardiogram criteria, he was admitted and started on an integrelin drip and heparin drip as well as p.o. aspirin and plavix. the integrelin and heparin drips both needed to be discontinued secondary to developing hematuria. the patient underwent a cardiac catheterization, which revealed 50% occlusion of the left anterior descending artery, 60% occlusion of the left circumflex coronary artery, 90% occlusion of the posterior right coronary artery and 70% occlusion of the mid right coronary artery as well as a critical aortic stenosis with an approximately 80 mmhg gradient. cardiothoracic surgery was subsequently consulted and the decision was made that the patient should undergo aortic valve replacement as well as coronary artery bypass grafting. the patient's preoperative hospital course was uneventful. he was hemodynamically stable and afebrile. on , the patient underwent uncomplicated coronary artery bypass grafting times one with a saphenous vein graft to the major obtuse marginal artery as well as an aortic valve replacement with a #21 bioprosthesis. the patient tolerated the procedure well and was transported to the cardiac surgery recovery unit intubated and in stable condition. in the unit, the patient was unable to be extubated initially secondary to respiratory acidosis. he was on neo-synephrine and nitroglycerin drips for blood pressure control as well as a dobutamine drip. in the early morning of postoperative day #1, the patient had been weaned to cpap and was subsequently extubated without incident. he was started on lopressor, the neo-synephrine and dobutamine drips were weaned and his nitroglycerin drip was discontinued. on postoperative day #2, the patient was arousable, moving all extremities to command. his chest tubes and foley catheter were discontinued and his diet was advanced. he was noted to have a wide complex tachycardia and was started on amiodarone. by the end of postoperative day #2, the patient was transferred to the floor in stable condition. on the floor, the patient remained afebrile and hemodynamically stable. the only major issue that the patient had was his delirium, which necessitated the placement of a one-to-one sitter. all sedating medications were held and the patient was frequently oriented with no effect. a psychiatry consultation was obtained, who recommended that the patient be started on low dose haldol 0.5 mg b.i.d. in an effort to clear up his delirium. this was started on postoperative day #7, at which time his one-to-one sitter was discontinued. he had no events overnight. on the morning of postoperative day #8, the patient's mental status seemed to be intact. the patient was subsequently discharged in stable condition to a rehabilitation facility on postoperative day #8. discharge medications: 1. lasix 20 mg p.o. b.i.d. times one week. 2. 20 meq p.o. b.i.d. times one week. 3. aspirin 81 mg p.o. q.d. 4. ibuprofen 400 mg p.o. t.i.d. 5. protonix 40 mg p.o. q.d. 6. colace 100 mg p.o. b.i.d. 7. percocet one to two tablets p.o. every three to four hours p.r.n. 8. albuterol nebulizers every four hours p.r.n. 9. lopressor 25 mg p.o. b.i.d. 10. captopril 25 mg p.o. t.i.d. 11. haldol 0.5 mg p.o. b.i.d. 12. amiodarone 400 mg p.o. t.i.d. times two days, then 400 mg p.o. b.i.d. times seven days, then 400 mg p.o. q.d. discharge examination: the patient was afebrile with stable vital signs. he was in no acute distress. he was alert and oriented times three. he had decreased breath sounds on the left with bilateral wheezing. his heart had a regular rhythm. his belly was soft, nontender and nondistended. his extremities were warm and well perfused. his incisions were clean, dry and intact. discharge diagnoses: coronary artery disease. congestive heart failure. critical aortic stenosis. status post coronary artery bypass
