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: past medical history: 1. coronary artery disease. 2. hypertension. 3. hypercholesterolemia. 4. benign prostatic hypertrophy. 5. status post cataract surgery. preoperative medications: 1. toprol xl 100 mg p.o.q.d. 2. accupril 20 mg p.o.q.d. 3. aspirin 325 mg p.o.q.d. 4. pravachol 10 mg p.o.q.d. 5. cardura 8 mg p.o.q.d. allergies: the patient has no known drug allergies. physical examination: initial physical examination revealed the pulse 85; blood pressure 104/64; oxygen saturation 94% on four liters nasal cannula. general: the patient's general appearance is comfortable. neck: elevated jvp at 9-cm. chest: crackles bilaterally 2/3rds of the way up, right greater than left. cardiovascular: normal s1 and s2; 2/6 systolic murmur at the apex. extremities: dorsalis pedis pulses are 2+ bilaterally. extremities are without edema.; abdomen: positive bowel sounds, soft, and nontender. laboratory data: data revealed the following: white blood cell count 8.0; hematocrit 38.3; platelet count 130; chem 7 sodium 139; potassium 3.8; chloride 101; bicarbonate 29; bun 25, creatinine 1.1; blood sugar 151; pt 12.9; ptt 30.2. chest x-ray showed severe pulmonary edema, asymmetrical, right greater than left. hospital course: the patient was taken to the cardiac catheterization laboratory on . cardiac catheterization showed ef of 45% with anterior-wall hypokinesis, 70% lad lesion, 100% old left circumflex lesion, 80% pda lesion, 1+ mr. the patient underwent echocardiogram on , which showed a mildly dilated left atrium, depressed left ventricular function with global left ventricular hypokinesis, 1+ ar, 1+ mr. the patient remained in the coronary care unit for diuresis and monitoring. the patient was taken the operating room on with dr. . the patient underwent a cabg times three, lima to the lad, svg to rca, svg to om. the patient was transferred to the intensive care unit in stable condition on dopamine infusion at 5 mcg/kg per minute. please see operative note for further details. the patient was weaned and extubated from mechanical ventilation on his first postoperative evening. dobutamine infusion was weaned off with the cardiac index greater than three. the patient was transferred from the intensive care unit to the floor on postoperative #1. the patient's chest tubes were removed on postoperative day #1. the patient began working with physical therapy. on postoperative day #2, the patient was able to ambulate 500 feet and climb one flight of stairs without any assistance. the patient was cleared for discharge by the physical therapy department. on postoperative day #3, the patient was cleared for discharge to home with his daughter. on postoperative day #3, the patient was noted to be mildly tachycardiac with rates in the 90s to 100s, sinus rhythm. the patient's hematocrit, at that time, was 23.4. this was discussed with dr. . the patient was hemodynamically stable and not symptomatic from his anemia. it was decided to discharge the patient on his current dose of lopressor. the patient is to followup in one week for adjustment of medications, as necessary. condition on discharge: temperature maximum 99; temperature current 99.1; pulse 93 sinus rhythm with occasional pvcs; blood pressure 126/76; room air oxygen saturation 97%. the patient's weight on was 73.5 kg. the patient's preoperative weight was 69 kg. the patient is neurologically intact. cardiovascular: regular rate and rhythm, positive rubs, no audible murmur. respiratory rate: breath sounds are clear bilaterally. gi: the patient has positive bowel sounds. abdomen: soft, nontender, nondistended. the patient is tolerating a regular diet. the patient has trace lower extremity edema. sternal incision staples are intact. the wound is clean, dry, and intact. there is no erythema or drainage noted. the patient's appendectomy site is clean and dry without erythema or drainage noted. laboratory data: data revealed the following: white blood cell count 8.8; hematocrit 23.4; platelet count 129. the chem 7 revealed sodium 140, potassium 4.2, chloride 103, bicarbonate 31, bun 15, creatinine 0.8. discharge diagnoses: 1. status post coronary artery bypass graft. 2. hypertension. 3. hypercholesterolemia. 4. benign prostatic hypertrophy. 5. status post cataract surgery. discharge medications: 1. lopressor 50 mg p.o.b.i.d. 2. pravachol 10 mg p.o.q.h.s. 3. niferex 150 mg p.o.q.d. 4. colace 100 mg p.o.b.i.d. 5. lasix 20 mg p.o.q.d. times two weeks. 6. 20 meq p.o.q.d. times two weeks. 7. aspirin 325 mg p.o.q.d. 8. ibuprofen 400 to 600 mg p.o., q.4-6h., p.r.n. the patient inquired about restarting his cardura, which he was on preoperatively for benign prostatic hypertrophy. the patient was told that he should wait several days before resuming the medication to ensure that his blood pressure and hemodynamics remained stable on his current medication regimen. the patient is to followup with dr. in three to four weeks. the patient is to return to the clinic in two weeks for wound check and staple removal. the patient is to followup with his cardiologist in three to four weeks at home. , 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 (aorto)coronary bypass of two coronary arteries angiocardiography of left heart structures diagnoses: subendocardial infarction, initial episode of care coronary atherosclerosis of native coronary artery pure hypercholesterolemia mitral valve disorders congestive heart failure, unspecified unspecified essential hypertension 

Answer: The patient is high likely exposed to
