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 56 year old female with a history of rheumatic heart disease and severe mitral stenosis, who had been developing gradual increase in congestive heart failure and was thus scheduled for a mitral valve repair. the patient had had chronic dyspnea on exertion which had been progressively increasing; no lower extremity edema. no fever, chills, chest pain, shortness of breath or abdominal pain. she had stable two pillow orthopnea. no rashes or urinary symptoms. past medical history: 1. rheumatic heart disease with severe mitral stenosis and mild aortic insufficiency. 2. cerebrovascular accident approximately one year ago with expressive aphasia and right hand weakness after stopping coumadin. 3. increasing cholesterol. 4. asthma. 5. status post cesarean section times two. 6. hypertension. medications: 1. coumadin 7 mg p.o. q. day. 2. penicillin vk 125 mg p.o. twice a day. 3. lipitor 10 mg tablet p.o. q. day. 4. folate 1 mg p.o. q. day. 5. calcium multivitamin one per day. 6. albuterol p.r.n. 7. cozaar 22.5, one tablet p.o. q. day. physical examination: on physical examination, she is in no acute distress. temperature maximum 98.5 f.; 64; 109/73; 16; 99% on room air. heent: pupils were equal, round and reactive to light. extraocular movements intact. oropharynx clear. pulmonary: lungs are clear to auscultation bilaterally. cardiac showed a regular rate and rhythm, ii/vi holosystolic systolic murmur; ii/vi diastolic murmur at the apex positive left. abdomen soft, nontender, nondistended, bowel sounds. extremities with no edema. two plus dorsalis pedis pulses and five out of five strength bilaterally. laboratory: on admission showed a white count of 6, hematocrit of 39.4, platelets 241. chem-7 142, 4.6, 102, 29, 18, 0.8 and 90. her inr was 3.3 and ptt of 38.7. hospital course: the patient was admitted to the hospital on , for management of her anti-coagulation prior to surgery as well as for an elective colonoscopy. she was on the cardiology service until the date of her surgery, . on , the patient underwent a mitral valve repair with a 29 millimeter mechanical valve. after surgery, the patient was transferred to the csru and was extubated on the evening of postoperative day number zero. on postoperative day number two, the patient was started on anti-coagulation. she was kept on a heparin drip and her goal inr was 3.0 to 3.5. the patient was diuresed with lasix. the patient continued to work with physical therapy throughout her postoperative course and was doing well with them. the physical therapist felt that a rehabilitation stay would benefit the patient and the plan was made for her to go the life care center in attenborough. on postoperative day number nine, , the patient's inr was 2.4. plans were made for her discharge to rehabilitation on when life care in attenborough had a bed. condition on discharge: stable. discharge status: to rehabilitation. discharge diagnoses: 1. status post mitral valve replacement with a 29 millimeter valve. discharge medications: 1. lopressor 100 mg p.o. twice a day. hold for systolic blood pressure of less than 100, heart rate less than 55. 2. vicodin one to two tablets p.o. q. four to six hours p.r.n. 3. lasix 20 mg p.o. twice a day. 4. lipitor 10 mg p.o. q. day. 5. colace 100 mg p.o. twice a day. 6. tylenol 650 mg p.o. q. four to six hours p.r.n. 7. milk of magnesia 30 cc. p.o. q. h.s. p.r.n. 8. dulcolax 10 mg p.o. or p.r. p.r.n. 9. pantoprazole 40 mg p.o. q. day. 10. coumadin with a goal inr of 3.0 to 3.5. discharge instructions: 1. the patient was sent home on a cardiac heart healthy diet. 2. she was to follow-up with dr. in four weeks. , m.d. dictated by: medquist36 procedure: extracorporeal circulation auxiliary to open heart surgery open and other replacement of mitral valve colonoscopy diagnoses: pure hypercholesterolemia unspecified essential hypertension atrial fibrillation asthma, unspecified type, unspecified rheumatic heart failure (congestive) late effects of cerebrovascular disease, aphasia mitral valve stenosis and aortic valve insufficiency
