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: patient is a 77-year-old gentleman with a history of left squamous cell carcinoma on his stomach and left flank, who underwent placement of tissue expanders on . the patient is returning for removal of the tissue expanders as well as excision of the left flank squamous cell carcinoma. previous medical history: 1. coronary artery disease. 2. hypertension. 3. melanoma of the stomach. 4. necrotizing fasciitis. 5. status post nephrectomy. 6. myocardial infarction x2. 7. angina. medications on admission: 1. cartia 100 mg p.o. q.d. 2. lopressor 50 mg p.o. b.i.d. 3. prazosin 5 mg p.o. b.i.d. 4. percocet 1-2 tablets p.o. q.4-6h. prn pain. brief summary of hospital course: the patient was admitted on and underwent the operative procedure performed by the purple surgery service with dr. and the plastic surgery service performed by dr. . patient tolerated the procedure without any difficulty and there were no complications. for full description, please see the operative notes dated . following the operation, the patient was transferred to the trauma sicu for initial recovery. patient was noted to have an increase in o2 requirement and tachycardia, and a chest x-ray at that time showed a right lower lobe collapse. following the patient's extubation, the patient's o2 saturation was 85% on 3 liters nasal cannula prompting his transfer to the sicu. on postoperative day #3, the patient underwent acute pulmonary decompensation with severe hypoxia and patient had to be reintubated. patient tolerated the reintubation without any difficulty. following the patient's intubation, the patient underwent a bronchoscopy and a bronchoalveolar wash was done. returning was blood tinged fluid from the left lobes. the fluid returned from the wash was cultured and grew out serratia marcescens. due to these cultures, the patient was placed on levofloxacin and zosyn. also on , the patient developed atrial fibrillation with his heart rate oscillating between the 90s to 160s. the patient was on a cardizem drip, and was given lopressor, which did not manage either his heart rate nor his rhythm. the patient was then started on amiodarone drip following 150 mg iv bolus. the patient had to be electrically cardioverted and then was able to maintain his rhythm on the amiodarone drip. over the next couple days through , the patient remained intubated and continued to produce large quantities of thick sputum, which hampered his extubation. patient did have one respiratory trial with decreased amount of peep, but this was not tolerated and the patient was maintained on the ventilator. patient had to be continually suctioned every 2-3 hours for a thick tan yellow sputum. from a cardiovascular standpoint, the patient remained in normal sinus rhythm and had no further episodes of atrial fibrillation. on , the patient was seen and evaluated by cardiology for an elevated troponin and a borderline mb index. patient was complaining of slight amount of chest pain corresponding to the increase in troponin, which was worrisome for evolving myocardial ischemia. it was advised that the patient would be increased on his beta-blocker, placed on aspirin, and to have an echocardiogram performed. the patient underwent echocardiogram on the and this showed the following: severe global left ventricular systolic dysfunction of multivessel coronary artery disease, and moderate mitral valve regurgitation. following the echocardiogram, the patient was placed on lisinopril 5 mg p.o. q.d. and increased up to 10 mg as he was able to tolerate that. it was also advised that the patient undergo a stress test with the resolution of his current acute illness either as an inpatient or following discharge. patient's toprol xl was also increased to 100 mg p.o. q.d. and the patient was continued on amiodarone 200 mg q.d. on , postoperative day #10, the patient was weaned down to pressure support, and was able to tolerate this well. patient continued to have vast quantities of thick white secretions. his lungs were clear overall. patient continued to be diuresed. planned to get 1-2 liters off per day. on , the patient was extubated and was able to maintain his oxygen saturations on 50% fio2 via face mask tent. patient was started on clear liquids and his diet was advanced as tolerated. on , the patient was transferred out of the unit onto the surgical floor. while on the floor, the patient had an uneventful recovery and was able to be discharged to acute rehabilitation facility. discharge disposition: the patient will be discharged to acute care facility. follow-up instructions: the patient was instructed to followup with dr. in weeks following discharge and dr. during the same time period. patient was advised to please call to make these appointments. discharge condition: the patient was discharged in good condition: afebrile, tolerating regular diet without difficulty, ambulating with assistance. maintaining oxygen saturations with supplemental oxygen. discharge diagnoses: 1. status post resection of squamous cell carcinoma of the left flank. 2. status post excision of sinus tract. 3. status post removal of tissue expanders. 4. status post ventral hernia repair. 5. omental flap harvest. 6. status post advancement of skin flaps. 7. myocardial infarction x2. 8. coronary artery disease. 9. reintubation for hypoxia. 10. prolonged intubation. 11. atrial fibrillation. 12. electrocardioversion. discharge medications: 1. plavix 75 mg p.o. q.d. 2. metoprolol 50 mg p.o. b.i.d. 3. lisinopril 5 mg p.o. q.d. 4. aspirin 325 mg p.o. q.d. 5. timolol malleate 0.5% drops one drop b.i.d. in both eyes. 6. amiodarone 200 mg tablets one tablet p.o. b.i.d. 7. lasix 20 mg p.o. q.d. 8. potassium chloride 20 mg p.o. q.d. while on lasix. 9. zosyn 4.5 grams iv q.6h. for 11 days. 10. reglan 10 mg iv q.6h. 11. lansoprazole 30 mg p.o. q.d. 12. metoprolol 5 mg iv q.6-8h. prn systolic blood pressure greater than 160. , m.d. dictated by: medquist36 procedure: venous catheterization, not elsewhere classified continuous invasive mechanical

Answer: The patient is high likely exposed to
