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: allergies: patient recorded as having no known allergies to drugs attending: chief complaint: myocardial infarction/unstable angina major surgical or invasive procedure: - cabgx4 (left internal mammary artery->left anterior descending artery, saphenous vein graft(svg)->obtuse marginal artery, saphenous vein 'y' graft to distal circumflex artery and posterior descending artery.) history of present illness: this 48-year-old patient with exertional chest pain was investigated and an angiogram showed very tight lesion in the circumflex and severe triple- vessel disease with 100% blockage of the right coronary artery and critical stenosis of the left anterior descending artery. he had persistent chest pain and hence was transferred urgently for emergency coronary artery bypass grafting. intraoperative transesophageal echocardiogram showed the ejection fraction to be about 45%. past medical history: hyperlipidemia myocardial infarction social history: works in a restaurant in food prep. current heavy smoker. mild alcohol use. family history: brother with cabg at 53. father with mi at age 75 physical exam: gen: wdwn in nad skin: warm, dry, no clubbing or cyanosis. heent: perrl, anicteric sclera, op benign neck: supple, no jvd, from. lungs: distant breath sounds anteriorly heart: rrr, no m/r/g abd: soft, nd/nt/nabs ext:warm, well perfused, no bruits, no varicosities neuro: no focal deficits. pertinent results: echo pre-cpb:1. the left atrium and right atrium are normal in cavity size. no atrial septal defect is seen by 2d or color doppler. 2. overall left ventricular systolic function is mildly depressed (lvef= 40-50 %). 3. right ventricular chamber size and free wall motion are normal. 4. there are simple atheroma in the descending thoracic aorta. 5. there are three aortic valve leaflets. the aortic valve leaflets are mildly thickened. no aortic regurgitation is seen. 6. the mitral valve leaflets are structurally normal. mild to moderate (+) mitral regurgitation is seen. 7. there is no pericardial effusion. there was an episode of inferior wall akinesis with 3+ mr, occasional pvc's and elevation of the pa pressures. after treatment with phenylephrine and nitroglycerine there was resolution of the rwma and improvement of the mr. post-cpb: on infusion of phenylephrine. a-pacing. preserved biventricular systolic function post-cpb. mr is now 1+. the aortic contour is normal post decannulation. 11:14am %hba1c-5.8 05:10am blood wbc-6.8 rbc-3.04* hgb-8.6* hct-24.9* mcv-82 mch-28.4 mchc-34.7 rdw-13.7 plt ct-269 05:10am blood glucose-92 urean-15 creat-0.7 na-139 k-4.0 cl-103 hco3-26 angap-14 brief hospital course: mr. was admitted to the on via transfer from for urgent coronary artery bypass grafting. he was taken from the intensive care unit to the operating room where he underwent four vessel coronary artery bypass grafting. please see operative note for details. postoperatively he was taken to the intensive care unit for monitoring. he later awoke neurologically intact and was extubated. beta blockade, aspirin and a stain were started. on postoperative day one, he was transferred to the step down unit for further recovery. mr. was gently diuresed towards his preoperative weight, the physical therapy service was consulted for assistance with his postoperatve strength and mobility. his chest tubes and wires were removed. on the evening of post operative day two he was found to have increased work of breathing with desaturation so he was returned to the indensive care unit. multiple sputum and blood cultures were sent to the laboratory in response to a very wet chest radiograph with questionable infiltrates. he was placed on vancomycin and zosyn originally for the same findings, and then switched to levofloxacin as cultures began to return negative. he was treated aggressively with bronchodilators and his respiratory status improved markedly. by post-operative day five he was no longer symptomatic and his chest radiograph had cleared. the patient continued to progress and was discharged home with vna services on pod6 in good condition. medications on admission: none discharge
