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: mr. is a 55-year-old gentlemen who is admitted to the hospital for coronary artery bypass graft. he initially presented in with a myocardial infarction which was catheterized at the time. his most recent catheterization was in at . he presented with a classic picture of chest pressure radiating down to the left arm. the pain woke him in his sleep and was unimproved by sublingual nitroglycerin. in the emergency department at in , he was placed on intravenous nitroglycerin, intravenous heparin, and given morphine for pain control. his pain improved slightly at that point, but did not completely resolve. he states that there were no electrocardiogram changes at that time. he had a exercise treadmill test on , which he managed to exercise for 2 minutes and had to stop secondary to shortness of breath and chest tightness. reportedly, 0. depressions were noted in v4 through v5 leads. he was catheterized at the on . after his catheterization, angiography showed a left main with no significant disease, left anterior descending mild disease, moderate diagonal disease, left circumflex with moderate om1 disease, right coronary artery dominant mild disease. a left ventriculogram showed anterior lateral and inferior hypokinesis, with an ejection fraction of approximately 50%. he was discharged home and did well subsequently to the catheterization. he was then referred to from dr. after outpatient cardiac catheterization for shortness of breath and mild angina. the catheterization in showed 40% mid left anterior descending, 60% stenosis in the superior pole of the diagonal, 50% proximal om1. he reports having shortness of breath with exertion such as walking upstairs, walking a block, and denies any other associated symptoms. occasionally he reports a twinge of pain in the left-side of his chest which resolves spontaneously. he denied any orthopnea, paroxysmal nocturnal dyspnea, lightheadedness, or edema. his coronary risk factors include: hypertension, hypercholesterolemia, insulin dependent diabetes, and a family history including his father and brother. used to smoke and has a 23 pack year history, but quit 10 years previously. family history: his family history was pertinent for a father dying of question of valve dysfunction at the age of 49, and his brother having coronary artery disease and angina in his mid 20s. past medical history: 1. coronary artery disease (myocardial infarction in percutaneous transluminal coronary angioplasty at that time and again in ). 2. diabetes mellitus for 19 years. insulin requiring. 3. gastroesophageal reflux disease. 4. hypercholesterolemia. 5. hypertension. 6. sleep apnea. past surgical history: 1. appendectomy. 2. percutaneous transluminal coronary angioplasty. 3. cerebral vascular accident three years prior. allergies: no known drug allergies. medications upon admission: 1. lantus insulin 60 units b.i.d. 2. regular insulin sliding scale. 3. enteric coated aspirin 81 mg po q.d. 4. prevacid 30 mg po q.d. 5. imdur 10 mg po b.i.d. 6. lescol 80 mg po q.d. 7. zestril 2.5 mg po q.d. 8. toprol xl 100 mg q.a.m. and 60 q.p.m. physical examination: mr. was a slightly obese gentlemen. his neurological exam was grossly intact. his heart rate was regular with normal s1, s2 and no extra heart sounds heard. he had clear lung fields. his abdominal exam was soft and nontender with normal bowel sounds. he had no bruits heard in the carotids. his peripheral limbs were warm with strong pulses and no edema present. coarse in the hospital: mr. was admitted to the hospital for coronary artery bypass graft after a catheterization showed a left ventricular ejection fraction of 45% with three vessel coronary artery disease. he was admitted on . in the operating room he underwent coronary artery bypass graft times four with the left inferior mamillary artery to the left anterior descending, saphenous vein graft to diagonal, saphenous vein graft to om, and saphenous vein graft to posterior descending artery. he was placed under general anesthetic and tolerated the procedure well. he awoke postoperatively with no complications. postoperatively, he had a low grade temperature of 100.2 degrees fahrenheit with otherwise stable vital signs. he remained intubated on postoperative day one and remained on a neo-synephrine drip. the neo-synephrine drip was tapered and he was weaned off of it by postoperative day two. that same morning he was extubated and he remained hemodynamically stable. on postoperative day two, he persisted with a low grade temperature of 100.4 degrees fahrenheit with otherwise stable vital signs. a chest tube was removed that day. on postoperative day three he did well and remained afebrile with stable vital signs and lasix was increased to 40 mg intravenously b.i.d. he continues to diurese well and was transferred to the floor by postoperative day four. he was planned for discharge on postoperative day five, but felt a little unwell. he did not complain of any chest pain, shortness of breath, or edema. it was just general discomfort. on postoperative day six, he felt better. he was tolerating his po intake well and ambulating independently at a level 5. the pain was well-controlled, and he was discharged home. was stable for discharge home. he was told to follow-up with his primary care
