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 48-year-old male with a past medical history of coronary artery disease status post stent to left main and lad in , hypertension, hypercholesterolemia, who complained of having substernal chest pain over the course of one week. patient had a routine appointment with his cardiologist on . had an ekg which showed a complete bundle branch block. he was admitted to to rule out mi and was negative by enzymes. he underwent a cardiac catheterization on , which showed a left main stent in place and patent, but there was question as to whether there was ostial stenosis. the patient was transferred to on . patient underwent a repeat cardiac catheterization at a high grade stenosis at the ostium of the left main just proximal to the stents. there was kinking of the left main at the origin of the stents. the lad had no stenosis and stents were widely patent, fully expanded. the left circumflex had a stent which had a suboptimal expansion in the mid portion. there was 70% stenosis of the large obtuse marginal 1 and another 50% stenosis in the mid lcx just after the take off of the left om-1. patient was admitted to cardiac surgery for coronary artery bypass graft on . past medical history: 1. as mentioned above, coronary artery disease status post stent to lad in , left main lad and left circumflex stent in . 2. hypertension. 3. hypercholesterolemia. the patient denies diabetes. allergies: patient denies any allergies to any medications. social history: the patient denies smoking, but drinks about two drinks per weekend. physical exam on admission: patient was afebrile, heart rate of 57, blood pressure 126/88 with respiratory rate of 18. patient was alert and oriented times three and not in any acute distress. heent examination showed pink, moist oropharyngeal mucosa. pupils are equal, round, and reactive to light and accommodation. neck was supple, no jvd were appreciated, no carotid bruits were heard. cardiovascular examination: regular, rate, and rhythm s1, s2, no murmurs were heard. respiratory examination: lungs were clear to auscultation bilaterally. abdominal examination: good bowel sounds, soft, nontender, nondistended. groins were without hematoma and without bruit. distal pulses dorsalis pedis and posterior tibialis were 2+ bilaterally. extremities were without edema. laboratory examinations: white count 7.4, hematocrit 39.8, platelets 192. chemistries: sodium 138, potassium 3.9, chloride 104, co2 25, bun 14, creatinine 0.9, glucose of 118, ast 29, alt 45, alkaline phosphatase 34, t bilirubin 0.5. urinalysis was negative. chest x-ray was clear without any infiltrates or consolidations. ho course: patient underwent a coronary artery bypass x3 on with dr. . the patient had lima to lad, saphenous vein graft to left pda, and saphenous vein graft to obtuse marginal. please see the operative report for further details. in the immediate postoperative period, patient was taken to the cardiac surgery recovery unit in stable condition and intubated. patient was successfully extubated on postoperative day 0, and postoperative pain was adequately managed with morphine. during postoperative day one, the patient had some ectopy for which the patient received electrolyte repletion. during postoperative day two, the patient was noted to have developed a subcutaneous emphysema over the neck and anterior chest. patient received a left sided chest tube with chest tube put to suction. it was also noted that patient had a right sided pneumothorax on his postoperative chest x-ray. therefore, patient also received a right sided chest tube with chest tube put to suction. patient's hematocrit postoperatively dropped down to 20.8 and the patient received transfusion of 1 unit of packed red blood cells, and patient received p.o. lopressor for beta blockade to suppress ectopy that patient had postoperatively. by end of postoperative day three, patient was well and was transferred to the regular floor. on postoperative day four, patient's hematocrit seemed to have drifted back down to 20.2 and patient received two more units of packed red blood cells. chest x-ray taken after insertion of chest tube showed resolution of the pneumothoraces and well expanded lung fields bilaterally. by postoperative day four, left chest tube was d/c'd without any patient's discomfort. on postoperative day six, the patient's right sided chest tube was also removed without any discomfort or shortness of breath. patient's subcutaneous emphysema which extended from the neck down to the anterior chest and down to the forearm bilaterally, remained stable and the patient is discharged on postoperative day seven after having completed all the physical therapy requirements for post coronary artery bypass graft recovery. laboratories on discharge: white count of 8.9, hematocrit of 29.3, platelets 272. chemistries: sodium 139, potassium 4.5, chloride 104, co2 28, bun 18, creatinine 0.8, glucose of 108, magnesium was 1.9. condition on discharge: stable. discharge disposition: discharged to home. discharge diagnoses: 1. unstable angina. 2. coronary artery disease status post stent in and . 3. postoperative subcutaneous emphysema and right sided pneumothorax. 4. hypertension. 5. hypercholesterolemia. 6. complete bundle branch block. discharge medications: 1. lasix 40 mg p.o. q.d. x1 week. 2. potassium 20 meq p.o. q.d. x1 week. 3. percocet 5/325 mg 1-2 tablets p.o. q.4h. prn pain. 4. tylenol 650 mg p.o. q.4h. prn pain, please skip a dose of tylenol if you are taking a dose of percocet. 5. aspirin 325 mg p.o. q.d. 6. plavix 75 mg p.o. q.d. 7. colace 100 mg p.o. b.i.d. 8. lopressor 100 mg p.o. b.i.d. 9. lipitor 10 mg p.o. q.d. fo: patient is to followup with his primary care physician, . in two weeks and is to have followup of his lfts for followup of his statin medications. patient is to followup with dr. his cardiologist in two weeks. patient is to followup with dr. in his office in four weeks. , m.d. dictated by: medquist36 d: 11:13 t: 11:31 job#: procedure: insertion of intercostal catheter for drainage insertion of
