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: service: ccu history of present illness: this is a 73-year-old gentlemen with a past medical history of three vessel coronary artery disease, status post a coronary bypass graft in with a saphenous vein graft to left anterior descending along with an saphenous vein graft to an om and an saphenous vein graft at that time was not used. patient was in his usual state of health until the morning of admission when he presented to an outside hospital with severe substernal chest pain that failed to radiate to the extremities, the jaw, or back. he did complain, however, of some shortness of breath, nausea, and diaphoresis. he states that his symptoms had been increasing in intensity for about one to two weeks, but the most intense he had experienced since his coronary artery bypass graft 20 years ago. he rates the pain as a 9 on a scale of . the patient attempted to relieve his chest pain with an antacid along with sublingual nitroglycerin. he was rushed to the emergency room. electrocardiogram failed to show any st changes, however, his troponin was 1.9 and his ck was 16.9. he was then transferred to for further evaluation. a catheterization on the revealed severely elevated filling pressures with a wedge of 25 and a left ventricular end-diastolic pressure of 30. cardiac output was 5.6 liters with a cardiac index of 2.5 liters/minutes/meters squared. the left ventriculography revealed a moderately depressed ejection fraction of about 41% along with global hypokinesis and a more severe inferior hypo-akinesis with 2+ mr. the coronary angiography revealed the left anterior descending totally occluded proximally. the left circumflex was a diffusely diseased vessel. the oms were completely occluded. the right coronary artery was also completely occluded proximally and was filling by collaterals. the graft angiography revealed a 95% ostial stenosis of the saphenous vein graft to the left anterior descending. the saphenous vein graft to the om had a 90% ostial stenosis along with an 80% mid stenosis and a 40% touchdown stenosis. the saphenous vein graft to the posterior descending artery was known to be occluded. a intraaortic balloon pump was placed and the patient was returned to the coronary care unit for further management. past medical history: 1. coronary artery disease, status post a coronary artery bypass graft in . it was a three vessel coronary artery bypass graft with an saphenous vein graft to the left anterior descending, an saphenous vein graft to the om and saphenous vein graft to the right coronary artery. 2. diabetes mellitus. 3. peripheral vascular disease. 4. hyperlipidemia. 5. hypertension. 6. hypothyroidism. 7. peptic ulcer disease. 8. gastroesophageal reflux disease. 9. gout. medications on admission: 1. aspirin 325 mg po q.d. 2. heparin. 3. metoprolol 12.5 mg b.i.d. 4. simvastatin 80 mg q.d. 5. losartan 50 mg q.d. 6. regular insulin sliding scale. 7. zoloft 200 q.d. 8. allopurinol 300 q.d. 9. pantoprazole 40 q.d. 10. synthroid 150 mcg q.d. allergies: patient reports no known drug allergies. social history: he is retired. he lives with his wife. reports a 40 pack year history. he quit at the time of his coronary artery bypass graft 20 years ago. he denies any alcohol or intravenous drug use. family history: significant for a mother who had coronary artery disease. physical examination: the patient was afebrile. a blood pressure of 102/64. heart rate of 92 beats per minute. respiratory rate of 24 breaths per minute. an oxygen saturation of 94% on six liters of nasal cannula. in general, this is an obese elderly gentlemen who was in no apparent distress. his pupils equal, round and reactive to light and his extraocular movements were intact. his mucous membranes was moist and his oropharynx was clear. patient had an extremely thick neck and jugular venous pressure and lymphadenopathy could not be appreciated. his heart was regular rate and rhythm with distant heart sounds. there was a faint systolic ejection murmur at the right upper sternal border. his lungs showed diffuse crackles, predominantly in the lower half of both lungs. he had decreased breath sounds in the apexes of both lungs. his abdomen was obese, nontender, slightly distended, but not firm. he had positive bowel sounds. his extremities had chronic venous stasis changes along with +2 pedal edema bilaterally. dorsalis pedis pulses were appreciated. laboratories upon admission: revealed a white blood cell count of 9.45, a hematocrit of 28.9, a platelet count of 248,000. sodium of 140, potassium 4.3, chloride 102, bicarbonate 27, bun of 31, creatinine of 1.2 and a glucose of 268. his calcium was 8.8, magnesium of 1.6, phosphate of 2.7. his inr was 1.2. electrocardiogram showed sinus rhythm. a first degree av block, left axis deviation, right bundle branch block, left atria was slightly enlarged. there were q waves in the inferior leads. there was also q waves in the anterior lateral leads. hospital course: this is a 73-year-old gentlemen with known coronary artery disease, status post a three vessel coronary artery bypass graft in who presented with severe saphenous vein graft occlusion. his problem list includes the following: 1. cardiac: the patient was evaluated by the cardiothoracic surgery team who felt that the patient was not a surgical candidate given the lack of touchdown sites and severely elevated procedureal risk. he was then referred to the interventional cardiology service for possible pci intervention on femoral-femoral bypass support. after reviewing the films, the interventional cardiology service felt that his two grafts were stentable but with severely elevated risk that was lower than redo cabg. he went to the laboratory and was placed on the bypass machine and successfully had his two occluded saphenous venous grafts stented. he was then returned to the floor. the intraaortic balloon pump was removed and the medical regimen was optimized. he had no evidence of post-procedure myocardial infarction. this included placing the patient on an aspirin, plavix, a low dose beta-, angiotensin receptor and a statin. an echocardiogram was performed which revealed that he had a left ventricular ejection fraction of about 40%. it also showed severe akinetic and hypokinetic left ventricle. the echocardiogram also estimated the patient to have +2 mitral regurgitation. during the patient's stay, he had no chest pain or other myocardial infarction symptoms. he remained in sinus rhythm with limited ectopy on telemetry. 2. pulmonary: the patient was electively intubated for agitation. during his time, he appears to have developed a possible aspiration pneumonia for which he was treated with levofloxacin, vancomycin, and flagyl. he was also aggressively diuresed secondary to pulmonary edema. he was successfully weaned from the ventilator and remained on nasal cannula oxygen at the time of this dictation. 3. renal: the patient's baseline creatinine was estimated at about 1.3. following the dye load that he received during his two procedures, he developed acute renal failure with a creatinine that bumped to 2.2. his medications were renally dosed and nephrotoxins were avoided. at the time of this discharge summary, his creatinine had decreased from 2.2 to 1.4. 4. hematology: following return of the catheterization laboratory, the patient started to have some bright red blood by the nasogastric tube. the integrilin was discontinued and his hematocrit was followed. he did receive two units of packed red blood cells during his stay and his hematocrit bumped appropriately. he remained on a proton pump inhibitor throughout his stay. the patient's blood was cleared very rapidly after discontinuing the integrilin and his hematocrit remained stable and he had no signs of hemodynamic instability. 5. endocrine: patient with a history of diabetes. his sugars were extremely elevated and the patient was placed on an insulin drip for better control. gradually, the insulin drip was weaned off and the patient was placed back on his home insulin dose. patient also has a history of hypothyroidism. he remained on his home dose of levothyroxine. 6. infectious disease: the patient had several fevers along with an elevated white blood cell count. multiple cultures were drawn. he showed that he had gram positive organisms growing out of blood cultures. these were later identified as a staphylococcus which was coag negative. he was treated with vancomycin. the patient also had a respiratory culture which grew out h. influenza. he was treated with levofloxacin. this concludes the discharge summary for from until . there will be another addendum which will cover his discharge medications and discharge planning along with his time course from this period on. , m.d. dictated by: medquist36 d: 01:58 t: 14:32 job#: procedure: continuous invasive mechanical ventilation for 96
