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 white male physician with past medical history significant for myocardial infarction who presented to the with two days of epigastric pain associated with fever and chills. on admission, the patient was hypotensive with a systolic blood pressure in the 60s and with creatinine 2.7. ct scan of the abdomen and pelvis obtained revealed dilated intrahepatic ducts and 1.5 cm stone in the common bile duct with a dilated common bile duct. past medical history: 1. status post myocardial infarction. 2. hypertension. 3. status post cholecystectomy in . current ejection fraction 58 percent from a negative mibi obtained in . allergies: the patient has no known drug allergies. medications: 1. aspirin 81 mg once daily. 2. atenolol 25 mg once daily. 3. vasotec 2.5 mg once daily. 4. lipitor 10 mg once daily. social history: the patient is a retired pediatrician. he denied tobacco, alcohol, or illicit drug use. family history: noncontributory. physical examination: on physical examination, the vital signs were 99.1, 95, 108/69, 17, 99 percent on 2 liters. in general, the patient was alert. he was oriented times three. he does not appear in any acute distress. heent: the pupils were equal, round, and reactive to light. normocephalic. no jvd, lymphadenopathy, or thyromegaly noted. cv: regular rate and rhythm without murmur. pulmonary: clear to auscultation bilaterally. abdomen: nondistended, soft, nontender to palpation. extremities: no peripheral edema. distal neurovascular intact. neurologic: the patient is moving all extremities. cranial nerves ii through xii intact. good motor and sensory function. hospital course: the patient presented to the on with complaints of epigastric pain associated with fevers and chills times two days. on admission, the patient's systolic blood pressure was in the 60s and his creatinine was 2.7. he was given intravenous fluids which increased his blood pressure. a ct scan of the abdomen and pelvis revealed dilated intrahepatic ducts with dilated common bile ducts and a 1.5 cm stone in the common bile duct associated with evidence of cholangitis. his lactate was 8.6. white blood cell count 14.4. the gi ercp service was contact and the patient underwent emergent ercp with sphincterotomy and stent placement. the patient's condition soon stabilized. he remained afebrile and in a stable condition throughout the rest of his hospital course. he remained in the icu for observation until hospital day number three, at which time he was transferred to the floor in stable condition. cardiology was consulted who recommended an echocardiogram which was obtained and revealed no evidence of vegetation with a normal ef of greater than 55 percent. the patient's laboratory values continued to trend downward including his white blood cell count which was 10 on the day of discharge and his total bilirubin which decreased from a level of 5 on admission to 1.0 on discharge. by hospital day number five, the patient was ambulating easily and again he was afebrile with vital signs very stable. he was tolerating a regular diet. he was without pain. he was discharged in good condition on hospital day number six with instructions to follow-up with the ercp attending and also with dr. . discharge medications: 1. aspirin 81 mg once daily. 2. enalapril 2.5 mg p.o. once daily. 3. atenolol 25 mg p.o. once daily. 4. levofloxacin 250 mg p.o. once daily times ten days. 5. flagyl 500 mg p.o. three times daily times ten days. discharge instructions: the patient is to seek medical attention if he experiences fever, chills, nausea, vomiting, or increased abdominal pain. final diagnosis: acute cholangitis. recommended follow up: dr. office at within the next few days after discharge in order to make a follow-up appointment. the patient is to contact dr. office at within the next week after discharge to schedule a follow-up appointment. major surgical or invasive procedures: ercp. condition on discharge: good. , procedure: venous catheterization, not elsewhere classified endoscopic insertion of stent (tube) into bile duct infusion of vasopressor agent diagnoses: unspecified essential hypertension acute kidney failure, unspecified unspecified septicemia severe sepsis old myocardial infarction cholangitis calculus of bile duct without mention of cholecystitis, with obstruction
