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: mr. is a 73-year-old male who presented during a routine physical examination with dr. with an abnormal ekg. the patient was promptly referred to a cardiologist who then obtained a stress echocardiogram that determined an ejection fraction of 40-45% with basal inferior, basal posterior, and inferior septal hypokinesis with severe akinesis of the septal portion consistent with prior myocardial infarction. given these findings the patient was referred to for cardiac catheterization. the patient underwent a cardiac catheterization on which determined that the left ventricular ejection fraction was 45% with right dominant coronary artery. the patient's left main coronary artery showed moderate calcification with left anterior descending coronary artery also with moderate calcification with d1 a dominant diagonal, with a 90% lesion with heavy calcification. additionally, the right coronary artery also showed occlusion in the mid segment but the distal vessel filled from the l-r collaterals. given these findings the patient was referred to the cardiothoracic surgery for coronary artery bypass grafting evaluation. past medical history: 1. hypertension. 2. hypercholesterolemia. 3. morbid obesity. 4. noninsulin dependent diabetes mellitus. 5. cataracts. 6. sleep apnea. 7. chronic obstructive pulmonary disease. 8. emphysema.

was administered for cardiac catheterization. social history: the patient is retired from tire company. the patient is currently married and lives in with his wife. physical examination: vital signs were temperature 97.4, pulse 80 and sinus, blood pressure 121/79, respiratory rate 20, 90% room air saturation. the patient is a well-developed, well-nourished male in no apparent distress at the time of discharge. the patient was fully oriented to time, place and purpose of why he was in the hospital. heent: sclerae anicteric. cranial nerves ii-xii were intact. no evidence of cervical lymphadenopathy. mucous membranes were moist with no evidence of oral ulcers. there was no evidence of cervical lymphadenopathy noted. chest: clear to auscultation bilaterally. the patient has a skin graft on the sternum which is well healing with no evidence of erythema, no evidence of purulent drainage, however some mild serosanguinous drainage was noted on the superior portion which was noted to be normal by the plastic surgical service. epigastric midline incision was also well healing without any erythema and no evidence of drainage. the chest was otherwise clear to auscultation bilaterally. cardiac: regular rhythm and rate, no evidence of murmurs. abdomen: soft, obese but nontender to palpation with positive bowel sounds and no evidence of hepatosplenomegaly and no inguinal lymphadenopathy. extremities: the right lower extremity is healing well with no edema and no erythema. laboratory data: as of the white blood cell count was 7.3, hematocrit 32.2, platelet count 440. sodium 138, potassium 4.3, chloride 103, bicarbonate 25, bun 32, creatinine 1.1, glucose 105, calcium 8.9, magnesium 2.1. hospital course: the patient is a 73-year-old male who presented to the cardiothoracic surgery service with right coronary artery dominant vessel occlusion in the mid segment and 80% mid segment lesion in the left anterior descending coronary artery mid segment lesion in the left anterior descending coronary artery along with d1a dominant diagonal with 90% lesion with heavy calcification. after obtaining a successful preoperative evaluation, the patient underwent an uncomplicated coronary artery bypass grafting x 4 (left internal mammary artery to left anterior descending coronary artery, saphenous vein graft to right posterior descending coronary artery, saphenous vein graft to obtuse marginal, saphenous vein graft to diagonal) on . postoperatively the patient was extubated and transfused with three units of packed red blood cells and four units of fresh frozen plasma with two units of platelets. the patient also maintained good oxygen saturation post extubation and maintained adequate blood pressures after lasix administration and beta blocker initiation. by postoperative day number two the patient's foley catheter was removed. that evening the patient developed an episode of rapid atrial fibrillation to 130-140 beats per minute which was treated initially with 10 mg of lopressor and 500 cc of normal saline bolus to maintain the systolic blood pressure greater than 100 mmhg. because of the hypotensive episode, 150 mg of amiodarone bolus was administered and the patient's rhythm converted to sinus. by postoperative day number four the patient's chest tubes were removed and the patient was anticipated for discharge. during the following day during a careful examination, a sternal click was found along with increasing pulmonary congestion with productive yellow cough. further evaluation was required and the patient was maintained in the hospital. by postoperative day number seven, the decision was made to take the patient back to the operating room to repair the sternal dehiscence. the patient underwent an uncomplicated sternal debridement and localization of substernal fat and closure with wires. the patient also underwent a bronchoscopy for the presence of productive cough. postoperatively the patient was taken to the cardiac surgery recovery unit for close observation and maintained on simv ventilation, and zosyn. the intraoperative bronchoscopy result revealed normal nares and nasopharynx, oropharynx, larynx, and mild secretions in the airways. given chest x-ray findings which showed bibasilar atelectasis and rather unimpressive bronchoscopy findings, the patient was initiated on aggressive chest physiotherapy regimen. vancomycin was also added during this time. the patient was then extubated on postoperative day number two following the sternal debridement and the patient maintained good oxygen saturation on four liters nasal cannula. however by postoperative day number six, the patient's sternum continued to drain a substantial amount of serosanguinous fluid and plastic surgery continued to examine the patient and closely monitor the necessity of incising the obvious area of infection. by postoperative day number eight the decision was made to take the patient back to the operating room for another sternal debridement with placement of split-thickness skin graft on the sternal wound site. this procedure occurred uneventfully however during the following day the patient required right chest tube placement to maintain reexpansion of the lung for the presence of pneumothorax. the patient's condition continued to improve following the second sternal debridement and split-thickness skin graft. despite the overall clinical improvement the patient continued to require ventilatory support following the second sternal debridement. the pulmonary service was consulted at this time and after careful examination, it was determined that the patient's diaphragm was working properly. the patient exhibited good strength along with a chest x-ray which did not show a focal infiltrate. the patient's effusions were also small and moderate on the ct suggesting that his persistent ventilatory dependence was not completely mechanical in nature. subsequently the patient's narcotic usage was decreased and the patient was continued to be weaned off of the ventilatory support. by postoperative day number 11 following the second debridement, the patient's mental status improved and the patient appeared to be breathing on minimal positive pressure support, therefore the patient was extubated successfully. by postoperative day number 13, the patient's pressure and oxygen saturation maintained adequate levels and physical therapy reevaluation was sought. the patient was also transferred to the floor given the stable clinical status. by the patient's white blood cell count rose moderately and urinalysis indicated the patient had developed a urinary tract infection following prolonged catheterization. the foley catheter was promptly removed and the patient was initiated on oral ciprofloxacin. by postoperative day number 17 following the second debridement, the patient's graft site continued to take well with no evidence of erythema or purulent drainage and the patient continued to progress adequately while being oriented x 3. at this time after discussion with the plastic surgery service the decision was made to discharge the patient to the rehabilitation service for wound care as well as for physical therapy for endurance training purposes. condition on discharge: good. discharge status: to rehabilitation facility. discharge diagnoses: status post coronary artery bypass grafting x 4 (lima to lad, svg to rpda, svg to om, svg to diagonal). discharge medications: 1. ciprofloxacin 500 mg p.o. b.i.d. x 3
