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 70 year old male with no cardiac history prior to , when he had an acute myocardial infarction while on a hunting trip in . he was admitted to a local hospital and received tpa. he was subsequently discharged to home. an echocardiogram at that time showed inferior and posterior as well as basal and septal ischemia and he was referred for cardiac catheterization. he then received two crown stents to the right coronary artery and an stent to the left anterior descending artery. the patient did well after the intervention and was scheduled for an elective knee surgery in but, before his surgery, he began to develop symptoms of chest discomfort. he consequently underwent another cardiac catheterization in , which showed branch vessel coronary artery disease, mild mitral regurgitation and mild diastolic ventricular dysfunction with an estimated left ventricular ejection fraction of 55%. he was medically managed since then. the patient is active daily. for the past few months prior to admission, he noticed increasing mild chest burning when he is exerting himself. this discomfort is relieved with rest. he sometimes needs to use nitroglycerin spray to relieve his symptoms. the patient's most recent echocardiogram was in . he exercised 15 minutes of protocol. he did experience chest discomfort with exercise, but his electrocardiogram was nondiagnostic. imaging at the time revealed a mild fixed inferior defect but no areas of ischemia, with an estimated left ventricular ejection fraction of 45%. given the increasing symptoms of chest pain on exertion, the patient underwent another cardiac catheterization prior to admission, on . this cardiac catheterization showed three vessel disease and left main coronary artery disease with normal left ventricular function and moderate diastolic dysfunction. specifically, the left main coronary artery showed a 70% to 75% stenosis of the distal segment. the left anterior descending artery showed a 50% proximal stenosis and the circumflex artery had minimal irregularities without significant flow limited lesions. the right coronary system had a 30% stenosis of the proximal segment. review of systems: the patient denied any symptoms of orthopnea, paroxysmal nocturnal dyspnea, claudication, edema or lightheadedness. past medical history: 1. hypercholesterolemia. 2. diabetes mellitus. 3. history of smoking. 4. myocardial infarction in , treated with tpa. 5. left anterior descending artery stents and right coronary artery stent in . 6. severe degenerative joint disease. 7. prostate cancer treated with lupron. past surgical history: , bilateral knee replacements. allergies: the patient has no known drug allergies. medications on admission: toprol xl 100 mg p.o.b.i.d., lipitor 60 mg p.o.q.d., aspirin 325 mg p.o.q.d., motrin 800 mg p.o.q.d., iron 325 mg p.o.b.i.d., multivitamins one p.o.q.d., zestril 10 mg p.o.q.a.m. and 5 mg p.o.q.p.m., glucovance as per instructions. social history: the patient works as a plumber. he is married. the patient has a history of smoking. physical examination: on physical examination, the patient was awake, alert and oriented times three, in no acute distress, healthy looking elderly male. he was afebrile with a heart rate of 60, blood pressure 132/72, and oxygen saturation 99% in room air. head, eyes, ears, nose and throat: no bruits, no jugular venous distention. lungs: clear to auscultation bilaterally. cardiovascular: regular rate and rhythm, ii/vi systolic ejection murmur at the apex, normal s1 and s2 sounds. abdomen: soft, nontender, nondistended, right groin without hematoma, no oozing, no bruits status post cardiac catheterization. extremities: no edema, pulses palpable bilaterally. laboratory data: admission hematocrit was 31.6, white blood cell count 6.7, platelet count 179,000, prothrombin time 12.6, partial thromboplastin time 27.7 and inr 1.1. urinalysis: negative. glucose was 174, bun 27, creatinine 0.7, sodium 136, and potassium 4.6. hospital course: the patient was admitted to the cardiac surgery service. his last cardiac catheterization performed on the day of admission showed 70% stenosis of the left main, 50% stenosis of the left anterior descending artery and 30% stenosis of the right coronary artery with an estimated left ventricular ejection fraction of 60%. at the time, it was decided that a surgical intervention would be appropriate given three vessel coronary artery disease. on , the patient underwent coronary artery bypass grafting times two with a left internal mammary artery to the left anterior descending artery and reverse saphenous vein graft from the aorta to the obtuse marginal coronary artery. the procedure was without any complications. please see the full operative report for details. the patient remained intubated and tolerated the procedure well. he was transferred to the intensive care unit in good condition. the patient remained in sinus rhythm with occasional premature ventricular contractions. he continued to make adequate urine. he was originally put on an insulin drip given his history of diabetes. the patient was started on a diuretic regimen, to which he responded well. physical therapy was consulted, who followed the patient throughout his hospitalization. on postoperative day number two, the patient had a fever of 101.3. his physical examination remained unremarkable. his incision was clean, dry and intact. he was started on lopressor. his hematocrit was 26.8 on postoperative day number two. his chest tube had a small air leak. the patient's insulin regimen was tightened to gain better control of blood sugar levels. on postoperative day number two, the patient was transferred to the regular floor in stable condition. he remained afebrile with a stable heart rate and blood pressure and adequate oxygenation. the patient was ambulating with assistance. his chest tube and pacing wires were removed as was his urine catheter. the patient was cleared by physical therapy to go home when medically ready. the patient remained in sinus rhythm without any events. he was discharged to home on in stable condition. condition on discharge: good. discharge status: to home. discharge diagnoses: 1. coronary artery disease, coronary artery bypass grafting times two. 2. diabetes mellitus. 3. hyperlipidemia. 4. degenerative joint disease. 5. hypertension. discharge medications: aspirin 325 mg p.o.q.d. toprol xl 100 mg p.o.b.i.d. lipitor 60 mg
