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: this 82-year-old white male with a history of cvas and severe rheumatoid arthritis who presented to the as a transfer from an outside hospital with rapid atrial fibrillation and chest pain. the patient initially presented to his urologist's office the morning of the 29th complaining of right-sided chest pain and flank pain, which had been present for one month, but was worse on the day of admission. the patient pain presented as sharp, nonexertional, mildly pleuritic, not associated with shortness of breath, nausea, vomiting or diaphoresis. the patient was sent home from the doctor's office after being told he was fine but called his doctor when he found himself unable to rise from a chair at home. the patient was found by ems to be tachypneic with heart rates in the 220s, irregular, with stable blood pressure. he was given adenosine up to 12 mg with no effect. he then received 20 mg intravenous diltiazem with heart rate in the 150s. the patient arrived at in the emergency room with a heart rate of 136. systolic blood pressure of 92. he was given diltiazem .25 mg intravenous times one and then a drip was started at 15 mg per hour. on interview, patient gave clear history of sudden onset of chest pressure at 2 p.m., mildly pleuritic with diaphoresis, mild shortness of breath, no electrocardiogram changes. the first enzymes were negative. blood pressure support was attempted with two liters normal saline. the 02 saturations decreased. patient was given esmolol drip, gtt, and then his heart rate down to the 90s but systolic blood pressure continued to be in the 90s. dopamine drip was then added when the systolic blood pressure went down to the 60s. chest x-ray was consistent with congestive heart failure and d dimer returned positive so heparin was started. the decision was made to transfer the patient to the at that point. they added levophed to increase the blood pressure and ceftriaxone was given empirically without blood cultures being drawn. the patient was transferred to with stable blood pressure on levophed, dopamine, diltiazem drip and esmolol drip. the esmolol drip and the diltiazem drip were discontinued on arrival at . also discontinued secondary to his low blood pressure. vancomycin and flagyl were given for presumptive sepsis. medical history: significant for rheumatoid arthritis, cva in with no deficiencies and a questionable possibility of having a transurethral resection of prostate back in . allergies: he had no known drug allergies. medications on admission: codeine, celebrex, prednisone 5 mg po q.d., prilosec, methotrexate, aspirin, folate, axid and xanax. social history: patient quit cigarettes when he was in his 60s. he does not drink alcohol. lives in , with his wife. family history: noncontributory. physical examination: temperature 99.1. heart rate of 121-126. heart rate 16-20. blood pressure 112/72. 02 saturation 96% on 100% nonrebreather. patient was alert and responsive. pupils equal, round and reactive. extraocular motions intact and full. oropharynx was unremarkable. neck was in a tag collar, no lymphadenopathy, no jugular venous distention noticed. heart was irregularly irregular with no murmurs, rubs or gallops. lungs showed diffuse loud crackles bilaterally. abdomen was soft, nondistended, nontender with positive bowel sounds. extremities showed trace pedal edema, 1+ pedal pulses bilaterally, the right groin femoral line was in place and was a triple lumen catheter. hospital course: on admission to the medical intensive care unit, the patient began to decompensate both from a blood pressure and a respiratory prospective. he was ultimately intubated around 3 p.m. and his blood pressure was maintained with four different pressor agents including vasopressin, dopamine, phenylephrine and levophed. he was also given antibiotics including ceftazidime, vancomycin and flagyl overall for presumed sepsis. the patient's blood pressure did not increase and in conversation with the family, the patient was made "do not resuscitate." his blood pressure and heart rate continued to decline. he was unable to be maintained and his heart eventually stopping and the ventilator was then discontinued. he was pronounced dead at 12:55 a.m. on the for presumed sepsis leading to cardiovascular collapse, respiratory failure, respiratory arrest and cardiac arrest. the family agreed to having an autopsy performed. , m.d. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours insertion of endotracheal tube arterial catheterization diagnoses: congestive heart failure, unspecified unspecified septicemia atrial fibrillation personal history of tobacco use acute respiratory failure personal history of other diseases of circulatory system unspecified disorder of kidney and ureter retention of urine, unspecified rheumatoid arthritis
