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 77-year-old gentleman with a history of aortic stenosis. the patient is morbidly obese with a longstanding history of hypertension. he complained only of mild dyspnea on exertion with no chest pain and rest symptoms. serial echocardiograms showed an increasing severity of his aortic stenosis. therefore, the patient was admitted in for cardiac catheterization. past medical history: his past medical history at that time was significant for hypertension, aortic stenosis, morbid obesity, remote tobacco history, and venous stasis ulcerations. past surgical history: surgical history was significant for left cataract surgery, tonsillectomy, variceal surgery. allergies: he stated an allergy to norvasc (which increased lower extremity edema). medications on admission: (his medications at that time included) 1. lisinopril 40 mg by mouth once per day. 2. spironolactone 25 mg by mouth once per day versus twice per day (depending on lower extremity edema). social history: remote tobacco use. he quit times four years. social alcohol use; decreased over the last four years. physical examination on presentation: the patient's height was 5 feet 10 inches, his weight was 310 pounds, his heart rate was 68 (sinus rhythm), his blood pressure was 146/60, his respiratory rate was 20, and his oxygen saturation was 99% on room air. in general, a well-developed obese gentleman with severely draining venous stasis ulcerations. he was in no acute distress. head, eyes, ears, nose, and throat examination revealed the sclerae were anicteric. not injected. the extraocular movements were intact. the neck was supple. there was no jugular venous distention. no bruits. there was no lymphadenopathy. the oropharynx was clear. cardiovascular examination revealed a regular rate and rhythm. there was a harsh 3/6 systolic perisystolic murmur. the lungs were clear to auscultation bilaterally. the abdomen was obese, soft, and nontender. bilateral groin tenia. extremity examination revealed bilateral venous stasis changes to just below the knees. positive ulcerations draining clear to green fluid on the right lateral leg and medial left leg. pulse examination revealed carotid pulses were 2+ bilaterally, radial pulses were 2+ bilaterally, femoral pulses on the catheterization site on the right were 2+, and popliteal pulses were 2+ bilaterally. neurologically, motor and sensory examinations were grossly intact. cranial nerves ii through xii were grossly intact. pertinent laboratory values on presentation: white blood cell count was 9.3, his hematocrit was 33.9, and his platelets were 288. sodium was 136, potassium was 4.7, chloride was 100, bicarbonate was 30, blood urea nitrogen was 23, and his creatinine was 1.1. his inr was 1.3. pertinent radiology/imaging: an electrocardiogram revealed a sinus rhythm with left ventricular hypertrophy and nonspecific st-t wave changes in v4 through v6. echocardiogram showed concentric left ventricular hypertrophy with severely dilated left atrium, and an ejection fraction of 75%, and a mild resting left ventricular obstruction. cardiac catheterization showed 50% left main, 30% left anterior descending artery, 40% diagonal, 20% right coronary artery, and an aortic valve area of 1.3 cm2. concise summary of hospital course: as stated previously, the patient was a direct admission to the operating room. on , the patient underwent an aortic valve replacement with a #23 pericardial tissue valve and a coronary artery bypass graft times one with a left internal mammary artery to the left anterior descending artery. please see the operative report for full details. the patient tolerated the procedure well and was transferred from the operating room to the cardiothoracic intensive care unit. at the time of transfer, the patient's heart rate was a paced at 91 beats per minute. he had a mean arterial pressure of 65 and a central venous pressure of 10. he had levophed at 0.1 mcg/kg per minute and propofol at 30 mcg/kg per minute. in the immediate postoperative period, the patient had a labile blood pressure. a bedside transesophageal echocardiogram done at that time showed some degree of systolic anterior motion. his levophed and neo-synephrine drips were weaned off, and he was treated with volume. following that, he was hemodynamically stable. his anesthesia was reversed, he was weaned the ventilator, and was successfully extubated. he remained hemodynamically stable throughout the postoperative day and on postoperative day one. on postoperative day two, the patient had a labile blood pressure requiring low-dose neo-synephrine to maintain an adequate blood pressure. he was also noted to have a white blood cell count of 21. he was pan-cultured and had a chest x-ray at that time. the chest x-ray revealed bibasilar atelectasis, but no evidence of failure, pneumothorax, or infiltrate. additionally, the patient's swan-ganz catheter was discontinued. once per day three, the patient was weaned from all cardioactive intravenous medications. his chest tubes were discontinued and diuresis was begun. once per day four, the patient continued to be hemodynamically stable. he remained in the cardiothoracic intensive care unit for vigorous pulmonary toilet. by postoperative day five, the patient continued to progress slowly. he was hemodynamically stable. his pulmonary status seemed to be slowly improving, and he was transferred from the intensive care unit to the two for continued postoperative care and cardiac rehabilitation. over the next several days, the patient had an uneventful hospital course. with the assistance of the physical therapy staff and the nursing staff, the patient's activity level was gradually advanced. on postoperative day six, his temporary pacing wires were discontinued. he continued to make slow progression in his activity level. on postoperative day seven, it was decided that the following day the patient would be stable and ready to be transferred to rehabilitation for continued postoperative care. at the time of discharge, the patient's physical examination was as follows. vital signs revealed his temperature was 97.2 degrees fahrenheit, his heart rate was 66 (sinus rhythm), his blood pressure was 118/60, his respiratory rate was 20, and his oxygen saturation was 93% on room air. his weight preoperatively was 291 kilograms. at discharge, his weight was 305 kilograms. laboratory data revealed his white blood cell count was 10.8, his hematocrit was 27.7, and his platelets were 262. sodium was 138, potassium was 4.4, chloride was 101, bicarbonate was 26, blood urea nitrogen was 32, creatinine was 1, and blood glucose was 142. physical examination revealed the patient was alert and oriented times three. he moved all extremities. he followed commands. respiratory examination revealed scattered wheezes throughout. cardiovascular examination revealed a regular rate and rhythm. normal first heart sounds and second heart sounds. no murmurs. the sternum was stable. the incision with steri-strips opened to air.
