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: is significant for chronic obstructive pulmonary disease, hypertension, congestive heart failure, coronary artery disease, status post coronary artery bypass graft in , paroxysmal atrial fibrillation and pacemaker secondary to complete heart block, peptic ulcer disease, alcohol use and anxiety. allergies: no known drug allergies. medications: lasix 80 mg p.o. q.d., spironolactone 25 mg p.o. q.d., buspar 10 mg p.o. t.i.d., aspirin 81 mg q.d., toprol xl 50 mg p.o. q.d., terazosin 20 mg p.o. q.d. social history: the patient lives with his wife at home. he denies any alcohol or drug use and quit smoking previously. physical examination: on admission vital signs:99.1, 106/92, 76, 26, 99% on nonrebreather. general appearance: a pleasant male in no apparent distress. skin: positive skin tenting. head, eyes, ears, nose and throat: anicteric, oropharynx clear. neck: jugular venous pressure at approximately 6 cm, no lymphadenopathy. cardiovascular: regular rate and rhythm, s1 and s2. pulmonary: diffuse rhonchi bilaterally. abdomen: positive distention, no abdominal tenderness, positive bowel sounds. extremities: no edema, no calf tenderness. neurologic: alert and oriented times three. rectal: brown stool, trace guaiac positive. laboratory data: white count 18.1, hematocrit 41.5 and platelets 127. electrolytes: 135, 5.0, 90, .7, 69, 3.5 an 193. coagulation studies: 13.6, 31.5 and 1.2. ck was 63, troponin 0.4. urinalysis was negative for leukocyte esterase, had large blood, negative nitrites, negative glucose but 750 rbcs, 11 to 20 white blood cells and moderate bacteria. electrocardiogram showed normal sinus rhythm at 76 beats per minute with primary av conduction and block and a pr interval of approximately 240. abdominal x-ray showed air filled loops of small bowel with colonic distention, fecal material in the cecum and colonic distention as well. chest x-ray showed heart size within normal limits, a pacemaker in place and no infiltrates, no pneumothorax, question of atelectasis in the right middle lobe. arterial blood gases: 7.30/73/96 with a lactate of 1.7. the patient was admitted to medical intensive care unit. he was treated for presumed pneumonia with likely component of congestive heart failure. however, his respiratory status continued to worsen with large amounts of secretions and increasing abdominal distention possibly, secondary to ileus, and the patient was intubated. he was treated with an aggressive bowel regimen with improvement in his ileus and decrease the distension. despite continued aggressive care, the patient remained ventilator dependent and was unable to be liberated from mechanical ventilation. he subsequently had a congestive heart failure exacerbation. given the patient's previously expressed wished, his family felt he would not want continued intubation and would want to be extubated. they understood that this would likely result in his passing away but felt strongly this was most consistent with his wishes. therefore, the endotracheal tube was withdrawn on and the patient was treated aggressively with lasix for his congestive heart failure and antibiotics for presumed pneumonia along with aggressive suctioning of his secretions. unfortunately, he passed away on the evening of from respiratory failure despite the aforementioned measures. he was kept comfortable throughout. , m.d. dictated by: medquist36 d: 20:16 t: 20:41 job#: procedure: continuous invasive mechanical ventilation for 96 consecutive hours or more insertion of endotracheal tube arterial catheterization diagnoses: acidosis urinary tract infection, site not specified congestive heart failure, unspecified acute kidney failure, unspecified atrial fibrillation obstructive chronic bronchitis with (acute) exacerbation acute respiratory failure pneumonia due to pseudomonas paralytic ileus 

Answer: The patient is high likely exposed to
