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: status post mi , chronic atrial fibrillation with anticoagulation, history of mitral valve prolapse with mild flail seen on echo in the past, and prostate problems (bph), status post turp times three, status post ccy. allergies: proscar, penicillin. medications: lisinopril, 10 mg po q d; metoprolol, 100 mg po t.i.d.; ranitidine, 150 mg po b.i.d.; simvastatin, 20 mg po q d; aspirin, 325 mg po q d. laboratory/diagnostics: patient's labs at the time of discharge, : white blood cell 9.5, hematocrit 28.3, platelets 395. chemistry: sodium 135, potassium 3.2, chloride 96, bicarbonate 27, bun 24, creatinine 1.4. pt 16.1, ptt 45.7, inr 1.7. calcium 8.4, phosphorus 3.8, magnesium 1.7. patient's potassium was replaced with approximately 80 meq of potassium prior to discharge. patient's magnesium was replaced with 4 grams prior to discharge. physical examination: vital signs: temperature 98, blood pressure 136/87, pulse 90 and irregular, history of atrial fibrillation, respirations 16, 95% on room air. heent: sclerae anicteric. cranial nerves ii-xii intact. no evidence of cervical lymphadenopathy. mucous membranes moist. on the right lateral surface of the tongue, there is an ulceration since the operation, probably caused from prolonged compression by endotracheal tube. chest: clear to auscultation bilaterally. irregular rhythm, rate, no appreciable murmur noted. sternotomy site was clean. no evidence of erythema, no evidence of drainage, and stability was confirmed with palpation. abdomen: positive bowel sounds. no evidence of hepatosplenomegaly. soft, nondistended, nontender. no inguinal lymphadenopathy noted. extremities: +1 symmetric edema, packings noted in the left lower graft site, as well as left lower leg. no evidence of erythema noted there, although serosanguinous drainage was obtained. hospital course: mr. is a 78-year-old male with past medical history remarkable for chronic atrial fibrillation and status post mi in , who presents with acute worsening of dyspnea on exertion evaluated by the medicine service with transesophageal echo, as well as cardiac catheterization. the patient's cardiac catheterization revealed 90% rca stenosis with pressure dampening and serial 70% lesions in the second diagonal branch of lad. additionally, the patient was noted to have severe mitral regurgitation with systolic function depressed with a calculated ejection fraction of 40% and global hypokinesis. given these findings, the patient underwent an uncomplicated mitral valve repair with resection of posterior leaflet and 28 mm annuloplasty ring placement. the patient also underwent an uncomplicated cabg times two (svg to diag, svg to rca). postoperatively, the patient was transferred to the csru, intubated, on levophed, vasopressant, propofol for sedation. on postoperative day one, the patient remained a paced - v paced with no evidence of ectopy and continued on simv ventilation. the patient's chest tubes remained on wall suction during this time. by postoperative day number two, the patient's pressure continued to improve and the pressors were weaned off. the patient was, also, extubated, oxygenating well, with only minimal supplemental oxygen via nasal cannula. by postoperative day number four, the patient was transferred to the floor in good condition with mild serosanguinous drainage noted in the left lower extremity of the graft sites. the patient was initiated on physical therapy for both rehabilitation screening purpose and for endurance training purpose. with increased drainage noted on the left lower extremity by the following day, the patient was initiated on levofloxacin for presumptive treatment of wound infection secondary to peri-incisional erythema which had worsened over a 24 hour interval. prior to initiating anticoagulation, patient's pacer wires were discontinued after successfully initiating a dose of metoprolol without any incidence of bradycardia. since the patient's weight had also substantially increased since admission, the patient's lasix dosing was also re-titrated higher. by postoperative day number eight, the patient was therapeutic on heparin drip at approximately 800 units per hour with ptt at 45.7 with goal range between 40-60. the patient's inr on the coumadin regimen had also increased to 1.7 with the expected target to be between 2-2.5. by postoperative day number nine, the patient was cleared by the physical therapy service, as well as the case management service, for a discharge to rehabilitation. the patient's anticoagulation regimen, at this time, was to be changed to coumadin 3 mg alternating with 4 mg. because, on the date of discharge, the patient's potassium level was found to be 3.2 after an aggressive diuresis, 80 meq of potassium was administered orally along with 4 grams of magnesium placement for a magnesium level of 1.7. these electrolyte values are to be rechecked on and potassium administration re-titrated to prevent any episode of hypokalemia. given the dramatic improvement in the patient's clinical status, decision was made to discharge the patient on to a rehab facility where patient can get the proper wound care for lower extremity wound dressing, dry packing, to be changed twice daily. condition on discharge: good. discharge status: per rehab facility. discharge diagnoses: status post mitral valve repair with resection of posterior leaflet and 28 mm annuloplasty ring, cabg times two (svg to diag, svg to rca). congestive heart failure. hypokalemia. re-titration of diuretics for hypovolemia. discharge medications: zaroxolyn, 5 mg po q d; lasix, 40 mg po t.i.d.; levofloxacin, 500 mg po q d times 10 additional days; coumadin, 4 mg, 3 mg to be alternated. patient is to be administered 3 mg of coumadin on as the initiating dose of the cycle. patient should also have a chemistry drawn on to check for presence of any hypokalemia or hypomagnesemia secondary to diuresis. metoprolol, 75 mg po t.i.d.; aspirin, 325 mg po q d; nystatin oral suspension, 5 cc po q.i.d.; potassium chloride, 40 meq po b.i.d. during the administration of lasix, as well as metolazone (this lowish should be re-titrated for adequate diuresis); simvastatin, 10 mg po q d; zantac, 150 mg po b.i.d.; colace, 100 mg po b.i.d.; tylenol, 650 mg po q 4 hours p.r.n. pain; dilaudid, 2-4 mg q 4-6 hours p.r.n. pain. follow-up plans: the patient was instructed to follow up with dr. in four weeks. patient was also instructed to follow-up with cardiologist, dr. , seven to ten days after discharge. , m.d. dictated by: medquist36 d: 09:39 t: 10:53 job#: procedure: extracorporeal circulation auxiliary to open heart surgery combined right and left heart cardiac catheterization coronary arteriography using two catheters (aorto)coronary bypass of two coronary arteries angiocardiography of left heart structures open heart valvuloplasty of mitral valve without replacement diagnoses: coronary atherosclerosis of native coronary artery other postoperative infection atrial fibrillation rheumatic heart failure (congestive) old myocardial infarction mitral valve insufficiency and aortic valve stenosis surgical operation with implant of artificial internal device causing abnormal patient reaction, or later complication,without mention of misadventure at time of operation drug-induced psychotic disorder with hallucinations 

Answer: The patient is high likely exposed to
