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 53-year-old male with a history of coronary artery disease status post multiple percutaneous transluminal coronary angioplasties with stents. he was symptom-free for two weeks status post the last stent. since then, he has had progressive angina and occasional angina at rest. no history of orthopnea, paroxysmal nocturnal dyspnea, or lower extremity edema. denies atrial fibrillation or transient ischemic attack. no claudication. past medical history: noncontributory. medications: aspirin 325 mg once daily, lopressor 25 mg twice a day, protonix 40 mg once daily, lipitor 20 mg once daily, norvasc 5 mg once daily. allergies: no known drug allergies. physical examination: cardiac: regular rate and rhythm, grade i/vi systolic murmur. pulmonary: clear to auscultation bilaterally. abdomen: soft, nontender, nondistended. extremities: no edema. hospital course: the patient was brought to the operating room on , where a coronary artery bypass graft x 4 was performed. left internal mammary artery went to left anterior descending, saphenous vein graft to diagonal, saphenous vein graft to obtuse marginal i, saphenous vein graft to obtuse marginal iii. the pericardium was left open. an arterial line and right internal jugular with a swan-ganz catheter were placed. two atrial wires as well as two mediastinal tubes and one pleural tube were placed. his ebb equals 98 minutes, xtl equals 66 minutes. postoperatively, the patient was transferred to the intensive care unit, where he was rapidly extubated. on postoperative day one, his mediastinal and pleural tubes were removed. he was kept in the intensive care unit for aggressive pulmonary toilet on postoperative day two. on postoperative day two, the patient was noted to have tachycardia and diaphoresis despite albuterol nebulizers and pain control. he began to become hypoxemic. a chest x-ray revealed a consolidation with pneumonia, for which levofloxacin and vancomycin were started. the patient was reintubated and was once again stable. a tte performed at that time revealed right ventricular hypokinesis and mild mitral regurgitation. no pericardial effusion, and the left ventricular ejection fraction was preserved. the patient was stable on the ventilator. he was on a neo-synephrine and propofol drip. tube feeds were started also on postoperative day two. the patient's hematocrit fell to 23 on two occasions, for which he received two units of packed red blood cells each time. the ventilator began to be weaned on postoperative day three, and on postoperative day four, the patient was extubated again. the neo-synephrine drip was also weaned. the patient was stable in the intensive care unit, and was transferred to the floor on , in the evening. this is now postoperative day seven. on the floor, he was slow with ambulation, but eventually improved significantly. he was tolerating a regular diet, and levofloxacin and vancomycin were discontinued. laboratories were stable, with a hematocrit of 32.3, white count 5.8, potassium 4.2, bun 21, creatinine .7. condition on discharge: stable. discharge medications: lopressor 25 mg twice a day, lasix 20 mg twice a day, potassium chloride 20 meq twice a day, colace 100 mg twice a day, aspirin 325 mg once daily, plavix 75 mg once daily, lipitor 20 mg once daily, protonix 20 mg once daily, tylenol and percocet one to two tablets by mouth every four to six hours as needed. discharge status: home. fop: with primary care physician in three weeks, follow up with dr. in four weeks. discharge diagnosis: 1. status post coronary artery bypass graft x 4 , m.d. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours (aorto)coronary bypass of three coronary arteries single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery coronary arteriography using two catheters left heart cardiac catheterization diagnostic ultrasound of heart insertion of endotracheal tube other bronchoscopy diagnoses: pneumonia, organism unspecified coronary atherosclerosis of native coronary artery intermediate coronary syndrome tobacco use disorder mitral valve disorders unspecified essential hypertension other and unspecified hyperlipidemia other complications due to other cardiac device, implant, and graft 

Answer: The patient is high likely exposed to
