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: the patient is a 65 year old male with a history of dyspnea on exertion for six to 12 months. an echocardiogram performed in revealed aortic stenosis with a left ventricular ejection fraction of 55% to 60%. the patient had an exercise tolerance test on which showed severe inferior defect with partial reversibility as well as reversible septal ischemia. cardiac catheterization was performed on , which revealed a left ventricular ejection fraction of 60%, pulmonary artery wedge pressure of 11 and aortic stenosis with a mean gradient of 22 mm of mercury with a valve area of 1.2 cm2. it also revealed three vessel coronary artery disease. past medical history: 1. hypercholesterolemia. 2. noninsulin dependent diabetes mellitus. 3. hypertension. 4. degenerative joint disease. 5. benign prostatic hypertrophy. medications on admission: atenolol, lipitor, glyburide and aspirin. allergies: the patient has no known drug allergies. physical examination: on physical examination on admission, the patient had a blood pressure of 171/71, pulse 53, sinus bradycardia, temperature 96.3 and oxygen saturation 98% in room air. general: well appearing middle-aged male in no acute distress. head, eyes, ears, nose and throat: unremarkable with the exception of some jugular venous distention. chest: clear to auscultation bilaterally. cardiovascular: regular rate and rhythm, normal s1 and s2, grade ii/vi systolic murmur. abdomen: soft, nontender, nondistended. extremities: without edema, 2+ dorsalis pedis and posterior tibialis pulses bilaterally. laboratory data: preoperative electrocardiogram revealed normal sinus rhythm. preoperative laboratory values were unremarkable with the exception of a glucose of 307. hospital course: the patient was admitted directly to the preoperative holding area and taken to the operating room on , where he underwent coronary artery bypass grafting times four as well as an aortic valve replacement with a 25 mm pericardial tissue valve. postoperatively, the patient was transported from the operating room to the cardiac surgery recovery room, where he was being atrially paced. he was on insulin and propofol drips. the patient was hemodynamically stable, however, due to increased chest tube output of approximately 400 cc/hour for the first couple of hours postoperatively, the patient was taken back to the operating room for re-exploration for bleeding on the evening of surgery. there was a small distal branch of the right internal mammary artery which was found to be bleeding, and repaired. postoperatively from the re-operative procedure, the patient was transported again to the cardiac surgery recovery room, where he remained hemodynamically stable. he was on a low dose neo-synephrine drip initially, which was weaned off within the first few hours of arrival. the patient was also on an insulin drip for a short while in the postoperative period. the patient was weaned from the mechanical ventilator and extubated on postoperative day one. he also transferred out of the intensive care unit to the telemetry floor on postoperative day one in stable condition. the patient had a physical therapy evaluation on , postoperative day one, and was begun on cardiac rehabilitation. on postoperative day two, , the patient remained in stable condition. his atrial pacing was discontinued and he had remained in normal sinus rhythm with a rate in the 80s and with a stable blood pressure. the patient was noted to have some decreased breath sounds bilaterally. a chest x-ray was obtained at that time, which revealed bibasilar atelectasis and small bilateral pleural effusions. later that day, the patient's foley catheter was discontinued as well as his chest tubes, and he began ambulating. on postoperative day three, the patient continued to progress from a physical therapy standpoint and remained stable hemodynamically. over the next two days, the patient continued to progress well. he remained hemodynamically stable and today, , postoperative day five, he remains stable and is ready to be discharged to home. condition on discharge: temperature 98.3, pulse 72, normal sinus rhythm, blood pressure 98/58, respiratory rate 18 and oxygen saturation 94% in room air. the patient's weight today is 111 kilograms, which is up seven kilograms from his preoperative weight of 104 and his blood sugar has been in the 90s. physical examination on discharge: the patient is alert and oriented with no apparent neurologic deficits. lungs are clear to auscultation bilaterally. heart sounds are a regular rate and rhythm. sternum is stable with incision clean, dry and intact. abdomen is soft, nontender and nondistended. extremities are warm and well perfused with some peripheral edema noted. the patient is also noted to have some blistering at his saphenous vein harvest site, however, there is no erythema or purulent drainage noted; there is a small amount of serous drainage. laboratory data: the patient's most recent laboratory values are from , which showed a white blood cell count of 11,000, hematocrit 26, platelet count 119,000, sodium 141, potassium 4.3, chloride 108, bicarbonate 24, bun 19, creatinine 0.6 and glucose 162. disposition: the patient is being discharged home today with visiting nurse follow-up due to the wound blistering on the right thigh area. dressing changes, if the patient is having blistering, should be vaseline or neosporin applied to the blistered area and a dry sterile dressing placed over that as long as it continues to have any blistering. follow-up: the patient is to follow up with dr. in one month for a postoperative check, telephone number . the patient is also to follow up with his primary care physician, . , in three to four weeks, or sooner if necessary. discharge diagnosis: aortic stenosis, status post aortic valve replacement. coronary artery disease, status post coronary artery bypass grafting. noninsulin dependent diabetes mellitus. hypertension. , m.d. dictated by: medquist36 procedure: (aorto)coronary bypass of three coronary arteries single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery diagnostic ultrasound of heart other esophagoscopy open and other replacement of aortic valve with tissue graft diagnoses: coronary atherosclerosis of native coronary artery intermediate coronary syndrome pure hypercholesterolemia diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled aortic valve disorders hemorrhage complicating a procedure 

Answer: The patient is high likely exposed to
