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 73-year-old female who originally presented with a persistent cough. at the time, a chest x-ray was performed, which showed an abnormal mediastinum. a suspicion was raised about a possible ascending aortic aneurysm. a follow-up ct scan was performed, which showed a 5.2 x 5.4 cm in diameter aneurysm that appeared to taper at the level of the innominate artery. the patient's echocardiogram showed good left ventricular function with mild left ventricular hypertrophy. in addition, the patient was noted to have a moderately dilated aortic root and 2+ aortic insufficiency with mild aortic stenosis, mitral regurgitation, and tricuspid regurgitation. in addition, the patient underwent cardiac catheterization preoperatively, which showed two vessel disease with disease in the left anterior descending artery, first diagonal, and a large obtuse marginal. the patient presented to cardiac surgery for a possible surgical intervention. past medical history: 1. coronary artery disease 2. hypertension 3. peptic ulcer disease 4. depression 5. valvular disease allergies: no known drug allergies. medications on admission: 1. zestril 40 mg by mouth once daily 2. imipramine 100 mg once daily 3. trazodone 100 mg daily at bedtime 4. atenolol 25 mg once daily 5. nexium as needed laboratory data: hematocrit 30.8, white blood cell count 9.1, platelets 72. glucose 110, bun 23, creatinine 1.4, sodium 137, potassium 4.5. hospital course: the patient was admitted to the cardiac surgery service. given the history of ascending aortic aneurysm and coronary artery disease, the patient underwent: 1. resection and repair of ascending aortic and proximal aortic arch aneurysm 2. coronary artery bypass graft x 1 3. aortic valve replacement the patient tolerated the procedure well, which was performed on . there were no complications. the resection and repair of the ascending and proximal arch aortic aneurysm was performed with hemi-arch-type repair using 26 mm gel-weave dacron tube graft. the aortic valve replacement was done with a 21 - pericardial bioprosthesis. the patient remained intubated and was transferred to the intensive care unit in stable condition. she remained intubated. the patient was diuresed appropriately. the patient was started on several medications to maintain her systolic blood pressure at 120 or below. on postoperative day one, the patient was noted to have decreased bowel sounds and dark-colored drainage from the mouth. vancomycin and levofloxacin were added empirically. the patient was continued on nitro drip to help maintain her pressures. she was also continued on lopressor and hydralazine, as well as labetalol. the patient was extubated on . she tolerated extubation well, without any complications. the patient was noted to have periods of confusion. of note is that the patient had to go back to the operating room for a chest evacuation of a hematoma and suturing of a bleeding vessel. cardiology was consulted to assist with blood pressure control. cardiology recommendation was to initiate more aggressive diuresis, to continue labetalol, captopril and hydralazine. her antidepressant medication (imipramine) was discontinued. the patient was transferred to the regular floor in stable condition. on , the patient appeared to be in increased respiratory distress. she had crackles on examination bilaterally. she was thought to be fluid overloaded. a chest x-ray done at the time showed bilateral pleural effusions, left significantly greater than right, with associated left lower lobe collapse/consolidation. the patient was diuresed more. an electrocardiogram was obtained, which showed no change. in addition, left thoracentesis was performed, with significant amount of fluid drained. in addition, a pigtail catheter was placed by bedside and fluid was drained with suction. a follow-up chest x-ray obtained on the following day showed significant improvement in the amount of fluid present in the lungs. consequently, the pigtail catheter was removed on . the other issue was the patient's decreased appetite, which has been going on for the last week or so. the patient was restarted on her outpatient dose of imipramine. she was encouraged to eat and also to ambulate. physical therapy was following her during the hospitalization course. the patient remained afebrile. she was improving her oxygenation. the patient was discharged to a rehabilitation facility in stable condition. condition on discharge: good. discharge disposition: rehabilitation facility. discharge diagnosis: 1. ascending aortic aneurysm status post resection and repair of the ascending aortic and proximal aortic arch aneurysm 2. coronary artery disease status post coronary artery bypass graft x 1 3. aortic valve replacement 4. hypertension 5. depression die instructions: 1. the patient is to follow up with her surgeon, dr. in approximately four weeks. 2. the patient is to follow up with her primary care physician, . , in approximately one to two weeks. 3. the patient is to follow up with the cardiologist in approximately three to four weeks. discharge medications: will be dictated separately. , m.d. dictated by: medquist36 procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery diagnostic ultrasound of heart enteral infusion of concentrated nutritional substances thoracentesis percutaneous [endoscopic] gastrostomy [peg] incision of mediastinum open and other replacement of aortic valve with tissue graft resection of vessel with replacement, thoracic vessels diagnoses: coronary atherosclerosis of native coronary artery unspecified pleural effusion unspecified essential hypertension thoracic aneurysm without mention of rupture hematoma complicating a procedure aortic valve disorders accidental puncture or laceration during a procedure, not elsewhere classified hemorrhage complicating a procedure 

Answer: The patient is high likely exposed to
