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: mrs. is a pleasant 73-year-old female who presented preoperatively for an electrode mitral valve replacement, as well as coronary artery bypass graft surgery. she has had recurrent episodes for congestive heart failure and chest pain. past medical history: 1. noninsulin dependent diabetes. 2. hypertension. admission medications: 1. glipizide. 2. atenolol. 3. univasc. 4. lasix. 5. isordil. 6. nitroglycerin patch. allergies: penicillin. admission physical examination: general: the patient is a well appearing 73-year-old female in no acute distress. skin: intact. head, ears, eyes, nose and throat: unremarkable. neck: no jugular venous distention. trachea was midline. lungs: clear to auscultation bilaterally. heart: regular rate and rhythm. abdomen: soft and nontender. extremities: warm and well perfused. neurologic: alert and oriented, had no carotid bruits. hospital course: mrs. presented to the hospital for an elective coronary artery bypass graft and a mitral valve replacement. she received this operation on with the following anatomy: 1. left internal mammary artery to lad. 2. saphenous vein graft to pda. 3. mitral valve replacement. 4. carotid endarterectomy. initially, mrs. postoperative course was unremarkable. she was transferred to the intensive care unit for her initial postoperative care. she was transferred out of intensive care on postoperative day #2 and was undergoing physical therapy for her discharge to home. on the night of , however, she developed atrial fibrillation which was not an unexpected event, given a large left atrium found intraoperatively. initially, her atrial fibrillation was managed with lopressor and had to be further managed with amiodarone loading. she was also started on anticoagulation as per recommendation by cardiology/electrophysiology. her anticoagulation was initially heparin drip which was switched to coumadin and once an inr of 1.5 or above was achieved, heparin was stopped. at this time, given her deconditioning secondary to bed rest and atrial fibrillation which was required because of tachycardia secondary to exertion, mrs. required a longer convalescence. her urine output was also found to be inadequate, which was assessed to be likely secondary to poor atrial kick. she therefore received transthoracic echocardiogram which was unchanged from her preoperative report. given these findings, she was reevaluated by cardiology and on she was cardioverted back into sinus rhythm. since her cardioversion, she has remained stable in sinus rhythm and her lopressor had to be decreased in dose secondary to higher dose during her atrial fibrillation for rate control. she currently need rehabilitation for physical therapy work and to meet discharge goals. her renal function is also improving post cardioversion. on discharge, she is able to ambulate, is tolerating regular diet, is voiding spontaneously. she is in sinus rhythm and her renal function is improving. she is to follow up with dr. in his office within one month and dr. for cardiology within one month. discharge medications: 1. amiodarone 400 mg po qd x1 month, starting , then 200 mg po qd, then as per cardiology. 2. colace 100 mg po bid. 3. glipizide 5 mg po qd. 4. zantac 150 mg po bid. 5. aspirin 325 mg po qd. 6. captopril 12.5 mg po tid. 7. lopressor 25 mg po bid. 8. insulin sliding scale regular before meals and at bed time with blood sugar of 200 to 250 give 3 units subcutaneous, with 251 to 300 give 9 units subcutaneous, with 301 to 350 give 12 units subcutaneous. the patient's blood sugars have been running in the high 100s. 9. lasix 20 mg po qd x3 days. 10. potassium chloride 20 milliequivalents po qd x3 days. follow up: dr. within one month and dr. in cardiology in one month. please monitor electrolytes while patient is on diuretic. discharge status: rehabilitation. discharge condition: good. discharge diagnoses: 1. mitral regurgitation. 2. coronary artery disease. 3. coronary artery bypass graft x2. 4. mitral valve replacement. 5. postoperative atrial fibrillation, now in sinus. , m.d. dictated by: medquist36 procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery other electric countershock of heart (aorto)coronary bypass of one coronary artery diagnoses: coronary atherosclerosis of native coronary artery intermediate coronary syndrome mitral valve disorders congestive heart failure, unspecified unspecified essential hypertension cardiac complications, not elsewhere classified atrial fibrillation paroxysmal ventricular tachycardia diabetes with ophthalmic manifestations, type ii or unspecified type, not stated as uncontrolled
