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: increasing angina major surgical or invasive procedure: four vessel coronary artery bypass grafting utilizing left internal mammary artery to left anterior descending; vein grafts to right coronary artery, obtuse marginal and diagonal. cardiac catheterization with insertion of iabp history of present illness: mr. has a known history of dilated cardiomyopathy, with an ef of 20%. previous workup at hospital in showed a large area of infarct involving the apex, anteroseptal and inferobasal wall on cardiolite study. viability studies at that time revealed no viability in the apex and anteroseptal wall but there was viability in the inferior wall. an echocardiogram in showed an lvef of 20% with mild mitral and tricsupid regurgitation. during this past year the patient has been experiencing chest pressure that occurs with exertion such as during sexual intercourse or when he is emotionally stressed (ex. when he is gambling). his chest pain is relieved with nitroglycerin. the pain does not radiate to his arm or jaw. he denies any doe, but does get sob when he lays himself flat or on his left side. he sleeps with 2 pillows at night. denies lower extremity edema, palpitations, dizziness, difficulty with erection, or claudication. past medical history: dilated cardiomyopathy, hypertension, chronic obstructive pulmonary disease - active smoker, mild mitral regurgitation social history: married, works as cab driver. speaks russian primarily. wife works at in the chemistry lab. he drinks vodka on weekends, smokes 40 pk-years. family history: no premature cad physical exam: vit: 96.8 55 149/67 16 99%ra gen: middle aged male, lying flat, in nad heent: perrla, eomi, mmm neck: no jvd cv: rr, soft heart sounds, pulm: ctab anteriorly, no w/c/r abd: + bs, soft, nt, nd ext: 2+ dp pulses b, no peripheral edema skin: no rashes or excoriations pertinent results: 04:30am blood wbc-6.8 rbc-3.54* hgb-10.7* hct-33.7* mcv-95 mch-30.2 mchc-31.7 rdw-15.0 plt ct-315 05:55am blood glucose-130* urean-24* creat-1.1 na-139 k-4.4 cl-104 hco3-28 angap-11 05:55am blood calcium-8.5 phos-3.7 mg-2.2 brief hospital course: mr. was admitted and underwent elective cardiac catheterization which was significant for severe three vessel disease with severely depressed left ventricular function. coronary angiography showed a right dominant system with complex 90% lesion in the left anterior descending involving a large diagonal; 70% stenosis of the first obtuse marginal and 70% stenosis of the mid right coronary artery. left ventriculography showed 2+ mitral regurgitation and a lvef of 15-20%. based on the above results, an iabp was placed to augment diastolic coronary filling. cardiac surgery was subsequently consulted for urgent surgical coronary revascularization. further evaluation included a tte which confirmed a dilated left ventricule and severe global left ventricular hypokinesis with relative thinning/akinesis of the antero-septum and anterior walls. the lvef was estimated at 20%; and there was only 1+ mitral regurgiation. the aortic valve was normal. he otherwise remained pain free on medical therapy and was cleared to proceed with surgery. given the iabp, he was maintained on intravenous heparin. on , dr. performed four vessel coronary artery bypass grafting utilizing left internal mammary artery to left anterior descending; with vein grafts to right coronary artery, obtuse marginal and diagonal. his operative course was uneventful and he transferred to the csru for further invasive monitoring. due to a postoperative coagulopathy and copious amounts of airway secretions, he remained intubated and sedated for several days. his bleeding eventually improved with multiple blood products and required no operative intervention. he went on to experience bouts of paroxsymal atrial fibrillation which was treated with amiodarone. the iabp was removed on postoperative day four. he maintained stable hemodynamics as he successfully weaned from inotropic support. he was eventually extubated on postoperative day six following diagnostic/therapeutic bronchoscopy. sputum cultures eventually grew out klebsiella pneumoniae and mrsa for which antibiotic therapy was adjsted accordingly. a picc line was placed for intravenous vancomycin while he was concomitantly placed on contact precautions. following extubation, he continued to require aggressive chest physiotherapy and suctioning. with diuresis, pulmonary toilet and antibiotics, his pulmonary status gradually improved. due to concern for aspiration, a bedside swallow study was performed on . this showed a normal, functional swallow with no signs of aspiration. on postoperative day nine, he transferred to the sdu. his pulmonary status continued to improve. by discharge, his secretions were significantly less and he was satting 96% on room air. just prior to discharge, the picc line was removed and vancomycin was discontinued. he will need to remain on levofloxacin for another two weeks. he remained in a normal sinus rhythm with first degree av block - no further atrial arrhythmias were noted. amiodarone was titrated accordingly. he maintained stable hemodynamics and tolerated an acei. given his depressed lv function, he will need to remain on an acei as an outpatient. he continued to make clinical improvements, and was eventually discharged to home on postoperative day 13. medications on admission: lasix 40 or 20 , carvedilol 6.25 , ramapril 5 , isosorbide mononitrite 30 qd, combivent discharge medications: 1. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day). disp:*30 capsule(s)* refills:*2* 2. aspirin 81 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po daily (daily). disp:*30 tablet, delayed release (e.c.)(s)* refills:*2* 3. oxycodone-acetaminophen 5-325 mg tablet sig: 1-2 tablets po q4h (every 4 hours) as needed for pain. disp:*40 tablet(s)* refills:*0* 4. atorvastatin calcium 10 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* 5. lisinopril 20 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* 6. amiodarone 200 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* 7. furosemide 20 mg tablet sig: one (1) tablet po twice a day for 1 weeks: for one week, then qd. disp:*60 tablet(s)* refills:*0* 8. potassium chloride 20 meq packet sig: one (1) packet po once a day. disp:*30 packet(s)* refills:*2* 9. levofloxacin 500 mg tablet sig: one (1) tablet po q24h (every 24 hours) for 2 weeks. disp:*14 tablet(s)* refills:*0* 10. pantoprazole sodium 40 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po q24h (every 24 hours). disp:*30 tablet, delayed release (e.c.)(s)* refills:*2* 11. albuterol-ipratropium 103-18 mcg/actuation aerosol sig: puffs inhalation q4h (every 4 hours). disp:*1 qs 1 month* refills:*2* discharge disposition: home with service facility: homecare discharge diagnosis: coronary artery disease -
