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 who had experienced a week's worth of crescendo angina, chest pain and shortness of breath. this ultimately led to this present admission. his past cardiac history includes two weeks of angina in that ultimately ended up in cardiac catheterization in , leading to diagnosis of a complex left anterior descending lesion. at that time, he underwent a percutaneous intervention and had balloon angioplasty. subsequent to this, he had a recurrence of his anginal symptoms in , therefore prompting another cardiac catheterization which showed a re-narrowing of the similar left anterior descending lesion and consequently underwent percutaneous transluminal coronary angioplasty, brachytherapy, and cutting balloon. after completing that, the patient was chest pain-free until approximately one week prior to this admission, when he began with the crescendo anginal symptoms, chest pain and shortness of breath that prompted him to be admitted on , where he underwent cardiac catheterization showing a right dominant circulation system with a 70% left anterior descending lesion with 90% distal disease past the site of the stent. on obtuse marginal i had an ostial and mid-lesions sequentially of 80% stenosis. the right coronary was 90% stenosed as well. the left circumflex had 30% disease, and 90% ostial lesion at the first run-off from the circumflex. his preoperative laboratories were notable for a hematocrit of 26, bun and creatinine of 19 and .9. past medical history: hypertension for seven years, hypercholesterolemia, coronary artery disease. past surgical history: percutaneous transluminal coronary angioplasty in , percutaneous transluminal coronary angioplasty in with brachytherapy and cutting balloon. he has also had an appendectomy in the distant past. allergies: no known drug allergies. medications on admission: aspirin 325 mg once daily, toprol 100 mg once daily, plavix 75 mg once daily, cozaar 50 mg once daily, lipitor 10 mg once daily, and a multivitamin. hospital course: he was admitted to the c-med service, where he was ultimately referred to the cardiac surgical care unit with dr. . consultation with dr. revealed that he necessitated coronary artery bypass graft, and the patient subsequently went to the operating room on . in the operating room, dr. performed a coronary artery bypass graft x 4, with left internal mammary artery to left anterior descending, saphenous vein graft to diagonal, saphenous vein graft to obtuse marginal i, sequentially to the obtuse marginal iii. the patient's pericardium was left open. he had a right radial a-line, a right internal jugular swan-ganz catheter, two ventricular and two atrial leads, as well as two mediastinal and one left pleural chest tube. he was on amiodarone and milrinone, as well as epinephrine, propofol, nitroglycerin and neo-synephrine. he was brought to the cardiac surgical recovery unit, where his drips were weaned to amiodarone .5, milrinone .6, and neo-synephrine .5 to maintain cardiovascular parameters of 83 and sinus, blood pressure of 99/40 after two units transfused, as well as shovel mask at 100% for the arterial blood gas of 7.34/46/113/26/-1. his lactate was 3.8, down from 4.8 postoperatively. his hematocrit was 26.6 after transfusion of two units for a hematocrit of 21. preoperative hematocrit was 30. bun and creatinine were 19 and .9. his mixed venous gases were checked. they ultimately revealed a value of greater than 60, and therefore no more blood transfusion was carried out. his milrinone drip was weaned. he was kept on oral amiodarone for ventricular ectopy and ventricular tachycardia that had occurred postoperatively. lasix and lopressor were held for blood pressure issues. his chest tubes remained for high outputs on postoperative day number one. he was started on a regular diet, and given a regular sliding scale insulin postoperatively. by postoperative day number two, he was transferred to the floor. the foley was removed. he was given a 48 hour course of diamox to start his diuresis. he was tolerating a full diet. his lasix, lopressor and aspirin were subsequently started. his hematocrit was 23. his bun and creatinine were 19 and .7 on day number two, and he was continuing on oral amiodarone. by postoperative day number three, the patient was up and mobilizing with physical therapy without any difficulty. he had no recurrence of his ventricular ectopy or ventricular tachycardia. his lopressor dosages were titrated. his wires were removed on postoperative day number three. he was given a physical therapy and rehabilitation screening, which ultimately revealed that he was ambulator and independent enough to warrant discharge to home. his hematocrit was 24, his bun and creatinine were 20 and .9 respectively on postoperative day three. by postoperative day number four, he was ambulating at a level iv. his chest tubes, foley and wires were all removed. his continued aggressive pulmonary toilet and, by postoperative day number five, he was at a level v, tolerating a full diet, with a hematocrit of 25, bun and creatinine of 22 and 1.0. his vital signs were 99.2 for a t-max, 75 and sinus rhythm, 100/59 for blood pressure. stable sternum was noted on examination. he had no drainage or erythema. his wound was open and dry to air. he had a regular heart rhythm, with no murmur or rub or gallop rhythm. his abdomen was benign. his lower extremities were warm and well perfused. the right saphenous vein graft site was clean, dry and intact, well approximated. trace edema with palpable pulses distally. discharge medications: lopressor 25 mg by mouth twice a day, k-dur 20 meq by mouth once daily, lasix 20 mg by mouth every morning for seven days, colace 100 mg by mouth twice a day, zantac 150 mg by mouth twice a day, aspirin 325 mg by mouth once daily, amiodarone 400 mg by mouth twice a day to continue for one week and then change to 400 mg by mouth once daily for two weeks and then end, lipitor 10 mg by mouth once daily, percocet 5/325 one to two tablets by mouth every four to six hours as needed. follow up: to be seen by dr. 30 days from the time of discharge. he will see his cardiologist after three weeks. he will have a wound check in seven days. he will also go home with vna services. no heavy lifting nor any driving for 30 days. condition on discharge: stable, afebrile, sinus rhythm. discharge status: to home with vna services. discharge diagnosis: 1. status post coronary artery
