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: past medical history: history is notable for the following: 1. hypertension. 2. arthritis. 3. urinary frequency. 4. status post hysterectomy. 5. status post cholecystectomy. 6. status post bladder suspension. medications: 1. premarin 0.625 mg po q.d. 2. miconazole 12.5 mg p.o.q.d. 3. detrol 4 mg p.o.b.i.d. 4. calcium 600 mg p.o.q.d. 5. multivitamin po q.d. 6. tylenol arthritis p.r.n. allergies: naprosyn gives her hives and lopid gives her increased liver function tests. physical examination: on physical examination, the blood pressure is 136/65; heart rate 72. neck: without carotid bruit. heart: regular rate and rhythm with a systolic murmur. lungs: lungs were clear to auscultation bilaterally. abdomen: soft, nontender. extremities: palpable peripheral pulses with no varicosities. cardiac catheterization demonstrated moderate-to-severe aortic stenosis with nonobstructive coronaries and normal pulmonary artery pressures along with a preserved left ventricular ejection fraction. hospital course: the patient was admitted to the cardiology service on , following her cardiac catheterization. the following day she was taken to the operating room, where she had an aortic valve replacement with a tissue prosthetic valve. she received a #21 ce valve. the procedure was remarkable for a transfusion requirement of 5 units of packed red blood cells, 4 units of fresh-frozen plasma and two units of platelets. total cardiopulmonary bypass time was 92 minutes. cross-clamp time was 70 minutes. postoperatively, the patient was taken intubated to the cardiac surgery intensive care unit. in the cardiac surgery intensive care unit she was extubated overnight, but required a neo-synephrine drip to maintain her blood pressure. she was slowly weaned off this drip throughout the course of the first postoperative day. by the morning of the second day she was stable enough to be transferred to the floor. however, that evening, she became tachycardiac to a pulse rate of approximately 120 to 130. the ekg at that time demonstrated a junctional tachycardia that was narrow complex in nature and very regular. she required significant doses of intravenously lopressor in order to control her rate. she ultimately required 25 units of lopressor iv and she was also transfused with one more unit of packed red blood cells. she remained stable overnight, but the following morning she had a recurrence of her tachycardia. in addition, she started to have some bronchospasm that was secondary to the iv lopressor and she may have also had an element of congestive heart failure. she was given intravenous lasix and treated with iv diltiazem. she converted after 15 mg bolus and she was started on a drip at 10 mg an hour. after this time, she remained stable. all of beta blockers were discontinued. the following day, she started to be loaded with oral diltiazem. by the 5th postoperative day, the oral diltiazem dosage increased and her drip was decreased. in addition, it became apparent at this time that she was going to need rehab following her surgery. she was started on subcutaneous heparin and screening for rehabilitation was initiated. during this time, she continued to be diuresed. she was essentially without complaint. she did require some intravenous doses of diltiazem for heart rates between 100 and 110 as her drip was being weaned and her oral doses were taking effect. on , the hospitalization was dictated in anticipation of her transfer to rehabilitation. we are anticipating that she is transferred to rehabilitation on , off her diltiazem drip, taking 90 mg po q.i.d. discharge medications: 1. diltiazem anticipated to be 90 mg po q.i.d. 2. colace 100 mg p.o.b.i.d. 3. zantac 150 mg po b.i.d. 4. lasix 20 mg b.i.d. times seven days. 5. potassium chloride 20 meq b.i.d. times seven days. 6. premarin 0.625 mg po q.d. 7. percocet 5/325 one to two po q.4h. to 6h.p.r.n. 8. tylenol 650 mg po q.4h. to 6h.p.r.n. 9. heparin 5000 units subcutaneously b.i.d. 10. oxazepam 10 mg po q.h.s.p.r.n. 11. milk of magnesia 30 cc po q.6h.p.r.n. on the afternoon of this dictation, a diabetes mellitus consultation was obtained as the patient has had some elevated blood sugars during this hospitalization and it could be that she has undiagnosed diabetes mellitus at which time she will likely be placed on an oral . the patient is to followup with her family physician, . in approximately two weeks. in addition, she is to followup with dr. in approximately four weeks. discharge diagnoses: aortic stenosis now status post tissue aortic valve replacement. secondary diagnosis: 1. hypertension, controlled. 2. previously undiagnosed adult onset diabetes mellitus. 3. junctional tachycardia, controlled. , m.d. dictated by: medquist36 procedure: extracorporeal circulation auxiliary to open heart surgery combined right and left heart cardiac catheterization coronary arteriography using two catheters angiocardiography of left heart structures injection or infusion of other therapeutic or prophylactic substance open and other replacement of aortic valve with tissue graft other conversion of cardiac rhythm monitoring of cardiac output by other technique diagnoses: pure hypercholesterolemia congestive heart failure, unspecified diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled cardiac complications, not elsewhere classified atrial fibrillation aortic valve disorders hemorrhage complicating a procedure arthropathy, unspecified, site unspecified 

Answer: The patient is high likely exposed to
