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 71 year old retired medical doctor who had percutaneous transluminal coronary angioplasty , for coronary artery disease. on workup, it was discovered that he had advanced t2 no distal esophageal gastric cancer, esophageal adenocarcinoma. past medical history: 1. coronary artery disease, percutaneous transluminal coronary angioplasty times two, no history of myocardial infarction. 2. chronic atrial fibrillation. 3. hypertension. family history: noncontributory. social history: he is an ex-smoker of greater than twenty years. he denied ethanol abuse. allergies: questionable allergy to penicillin. physical examination: on admission, physical examination was unremarkable. hospital course: he was taken to the operating room on , for an esophagogastrectomy using approach by dr. and dr. , assistants dr. and dr. , general endotracheal anesthesia. please see the operative note for full details. postoperatively, the patient was doing well. he had an epidural and we were using lopressor for rate control and he was in the intensive care unit at that time. he was on vancomycin and flagyl postoperatively. on postoperative day one, the patient was transferred from the post anesthesia care unit to the floor. acute pain service was involved with reverse pain control. on , at 4:00 p.m. the patient's blood pressure dropped to 70/40 with the heart rate in the 100s. electrocardiogram showed atrial fibrillation. urine output had dropped to 15 ccs per hour since 7:00 a.m. that morning. he was bolused. at 2:00 a.m. on , the patient went to cardiac arrest and was resuscitated and was sent to the intensive care unit. central lines were placed and the patient was in grave condition. the patient's kidney function was slightly affected as he went into some degree of renal failure with a rising creatinine which resolved toward his discharge date. the patient was intubated and sedated in the unit. on the evening of , the patient was extubated and was alert and confused and was again in atrial fibrillation. the patient remained in the unit anticoagulated on heparin with chest tubes and nasogastric tube. the patient's creatinine at this point had decreased to 1.5 from a high of 2.2. the patient on postoperative day five, , had recovered well and was transferred to the floor where rate control was an issue. the patient was getting tube feeds and was npo. pca was discontinued. foley was discontinued and central line was discontinued on . on , it was noted that the patient's white count had increased and his back wound was dehiscing. the middle third was opened and drainage came out. he was packed with gauze. the patient was continued on vancomycin, levofloxacin and flagyl. the patient was confused and a code purple was declared on , and psychiatry was involved. his haldol was changed and adjusted. heparin was discontinued on the patient on , and coumadin was begun since his inr was now therapeutic. for the rest of the stay and postoperative day number nine, we continued the antibiotics. his chest tube was put to water seal. the patient's chest tube was removed. on , inferior aspect of the abdominal wound was showing some drainage and the patient's diet was being advanced and we continued wet to dry dressings at this point. however, the patient was then made npo. the patient's tube feeds continued. cat scan was done on the patient and showed question of a leak. on , the ct scan questioned a leak, however, no direct leak was seen as some retromediastinal and supradiaphragmatic air and debris was seen. the patient had a nasogastric tube placed by fluoroscopy on 0/25/02, and nutrition was once again involved as he was made npo as previously stated. electrolytes were repleted. the patient's inr was continuously adjusted to be 2.0 to 2.5 and lovenox was temporarily used for two days until for a moment when his inr dropped below 2.0. at the patient's behest, a medical consultation was called on , with regard to controlling his atrial fibrillation. an echocardiogram was done to check his left ventricular function and right ventricular function which came back normal. we continued vancomycin, levofloxacin and flagyl. barium swallow ct was done on , which showed the question of a leak as well. however, no direct leak was seen. the patient was transfused one unit of packed red blood cells to adjust for hematocrit which had fallen to 22.0 range and lopressor was changed to 50 mg p.o. t.i.d. in an attempt to control his atrial fibrillation. during this time of admission on , and onward, we were using lasix to help diurese the patient. the patient was complaining of edema and was noted to be puffy and likely fluid overloaded. the patient had an episode of ventricular tachycardia on , which was nonsustained and seven beats long and a cardiology electrophysiology consultation was called. they suggested increasing his lopressor and discontinuing the diltiazem which we did. they suggested a blood transfusion, discontinuing diltiazem and lopressor to be 100 mg t.i.d. which we did. the patient's nasogastric tube was discontinued on , had a ct scan which showed unlikely to be a current leak since no communication was seen between the collections and esophageal and gastric anastomosis. the patient was allowed to have a clear liquid diet which he tolerated. discharge summary addendum to follow. , m.d. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours other enterostomy insertion of endotracheal tube enteral infusion of concentrated nutritional substances total esophagectomy diagnoses: coronary atherosclerosis of native coronary artery
