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 patient is a 63-year-old man with past medical history significant for diverticulitis and ventral hernia repair with mesh who presented to the er at 2 a.m. with 12 hours of abdominal distention, nausea, vomiting x1, and pain, which the patient described as being more like fullness. he denied any fever or chills, chest pain, or shortness of breath. these symptoms have not happened previously. past surgical history: notable for a colostomy and colonic resection in for perforated diverticulitis, which was subsequently reversed and a ventral hernia repair with mesh in . the patient has also had a right total hip replacement. past medical history: ankylosing spondylitis. allergies: the patient has no known drug allergies. current medications: 1. hydrochlorothiazide 12.5 mg. 2. toprol 50 mg. 3. diovan 80 mg. 4. piroxicam 20 mg for arthritis and the ankylosing spondylitis. social history: the patient smokes one to two cigarettes per week and is a social drinker. physical examination on admission: temperature 99.2 degrees, pulse 86, blood pressure 125/99, respiratory rate 16, and saturating at 97 percent on room air. lungs are clear to auscultation bilaterally. heart is regular rate and rhythm. abdomen is soft and somewhat distended with diffuse mild tenderness. the patient has no rebound. no evidence of hernia. rectal examination is without masses and guaiac negative. laboratory data: on transfer from the outside hospital, white count 17.6, hematocrit of 48.1. chem-7 within normal limits, although notation is made of a creatinine of 1.2. hospital course: the patient was seen and examined by dr. and dr. . the initial plan on his presentation was to place a nasogastric tube, make the patient n.p.o., hydrate with iv fluids, and attempt nonoperative management depending on the patient's clinical course. later on that evening, however, it was felt that the patient was appearing to have developed a complete obstruction and the patient was taken to the operating room for an exploratory laparotomy and extensive lysis of adhesions. please refer to the operative note by dr. for more details on that operation. due to the patient's history of ankylosing spondylitis and a very difficult intubation, postoperatively, the patient was transferred to sicu where he had a stable course without significant incident. on postoperative day two, , the patient was transferred to the floor. vital sings were stable. breath sounds continued to be somewhat coarse. physical examination was otherwise unremarkable. the patient's wound was noted to be clean, dry, and intact. the patient was encouraged to ambulate as much as possible and was given aggressive pulmonary toilet with regards to incentive spirometer use and early ambulation. pain control was managed with the patient- controlled analgesia pump. on , it was noted that the patient's condition continued to improve. note was made of slight erythema at the left margin of his incision and the abdomen was otherwise soft. no focal tenderness. due to the patient's improving clinical status, the nasogastric tube was discontinued on and his diet was advanced to sips and clear liquids. the foley was taken out and the patient continued to improve. on , the patient continued to improve, although it was noted that he felt a slight bloating sensation even on the clear sips and the patient's diet was not advanced further that day. late in the evening of , in fact at 12:30 a.m. on , house staff was called to see the patient for a ten-beat run of ventricular tachycardia on the telemetry monitor. the patient was also complaining of left shoulder pain that was focal and nonradiating. the patient denied diaphoresis or shortness of breath, although he did have a slight episode of nausea prior to the event. note was made of a significantly elevated blood pressure to 190/100, other vital signs were unremarkable. the patient was given a 1 mg of morphine sulfate for pain control and an increased dose of intravenous lopressor. the patient's blood pressure came down to 180/102. the patient was alert, somewhat anxious, and was not diaphoretic. heart was regular rate and rhythm. lungs were clear to auscultation. a 12-lead ekg was performed and no change was appreciated from his ekg of . other measures initiated at that time were to restart the patient on his home dose of diovan, increase his iv lopressor dose to 10 mg q.6 h. he was started on aspirin 325 mg and was given an order for nitro paste as necessary and electrolyte check in the morning. results of stat chemistry showed a low magnesium of 1.4; this was appropriately repleted; and on recheck, the patient's magnesium rebounded to 2.6. the patient was once again made n.p.o., although the ng tube was not replaced. throughout the day of , the patient continued to do well and tolerated limited p.o. intake. after being initially n.p.o. that morning, he was seen and examined by the attending once again. after this hypertensive event, his blood pressures had stabilized to 165/91. his cardiac enzymes were negative for infarction. the patient's diet was gradually advanced; and on , the patient was given a regular diet, which he tolerated well. also on , the patient had one bowel movement, which was considered an encouraging sign of return of bowel function. he was transitioned to entirely oral medicines. the patient continued to do well throughout the day. on , the patient was once again feeling very well. his abdominal examination was reassuring. the incision was noted to be clean, dry, and intact. it was decided to discharge the patient home in good condition. discharge medications: the patient was discharged home on his customary cardiac regimen of 50 mg toprol xl q.d., 80 mg of diovan q.d., and 12.5 mg of hydrochlorothiazide q.d. discharge instructions: the patient was given instructions to return to see dr. in one week for removal of the staples. discharge diagnoses: partial small bowel obstruction. ankylosing spondylitis. postoperative hypotension. postoperative volume depletion. acute hypertensive crisis. , procedure: venous catheterization, not elsewhere classified arterial catheterization other lysis of peritoneal adhesions suture of laceration of small intestine, except duodenum diagnoses: other iatrogenic hypotension unspecified essential hypertension cardiac complications, not elsewhere classified accidental puncture or laceration during a procedure, not elsewhere classified paroxysmal ventricular tachycardia intestinal or peritoneal adhesions with obstruction (postoperative) (postinfection) 

Answer: The patient is high likely exposed to
