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: coronary artery disease major surgical or invasive procedure: - coronary artery bypass grafting x2 (left internal mammary-left anterior descending artery, saphenous vein graft-obtuse marginal artery). history of present illness: this 83 year old gentleman with a history of coronary artery disease underwent angioplasty in . he has recently had worsening dyspnea on exertion and angina. a cardiac catheterization was performed which revealed significant three vessel disease and mild aortic stenosis. he was admitted for elective revascularization. past medical history: coronary artery disease mild aortic stenosis hyperlipidemia hypertension non-insulin dependent diabetes mellitus benign prostate hypertrophy mild chronic renal insufficiency anemia of uncertain etiology social history: retired. lives with his wife. smoked and rarely drinks alcohol. family history: brother s/p bypass surgeries. father had coronary artery disease physical exam: admission: on examination, his heart rate is 72 and regular. blood pressure on the right is 160/70 and on the left of 142/70. he is 6 feet tall weighing approximately 198 lbs. he does have a faint intermittent tremor, which may be intention. i do not believe, it has been worked up. his skin is unremarkable. pupils are equal round and reactive to light and accommodation. eoms are intact. sclerae is anicteric. oropharynx is unremarkable. neck is supple with full range of motion. no jvd is appreciated. lungs are clear bilaterally. heart has regular rate and rhythm with a grade iv/vi systolic ejection murmur heard throughout his precordium and up into his carotids. abdomen is soft, nontender, and nondistended with positive bowel sounds. no hepatosplenomegaly or cva tenderness is detected. extremities are warm and well perfused without any varicosities. he does have trace bilateral lower extremity edema. he is neurologically grossly intact with a nonfocal examination and moving all extremities with 5/5 strengths. he has 2+ bilateral femoral dp, pt, and radial pulses. his murmur transmits into his carotids versus possible carotid bruit. pertinent results: echo pre-bypass: the left atrium is moderately dilated. no spontaneous echo contrast is seen in the body of the left atrium or left atrial appendage. no thrombus is seen in the left atrial appendage. no atrial septal defect is seen by 2d or color doppler. there is mild symmetric left ventricular hypertrophy with normal cavity size. regional left ventricular wall motion is normal. left ventricular systolic function is hyperdynamic (ef>75%). right ventricular chamber size and free wall motion are normal. the aortic root is moderately dilated at the sinus level. there are simple atheroma in the aortic arch. there are simple atheroma in the descending thoracic aorta. the aortic valve leaflets (3) are mildly to moderately thickened. there is moderate aortic valve stenosis with valve area of 1.2cm2 calculated by doppler assessment and valve area of around 1.5 cm2 by planimetry. trace aortic regurgitation is seen. the mitral valve leaflets are mildly thickened. trivial mitral regurgitation is seen. there is no pericardial effusion. dr. was notified in person of the results in the operating room at the time of the study. post-bypass: the patient is in sinus rhythm. there is normal biventricular systolic function. the left ventricular ejection fraction is about 70%. there is no change in valvular function compared to the pre-bypass study. the thoracic aorta appears intact. 07:30am blood wbc-10.5 rbc-3.19* hgb-9.9* hct-29.3* mcv-92 mch-31.0 mchc-33.7 rdw-13.5 plt ct-141* 07:30am blood glucose-76 urean-41* creat-1.9* na-137 k-3.7

course: mr. was admitted to the on for surgical management of his coronary artery disease. he was taken to the operating room where he underwent coronary artery bypass grafting to two vessels. of note, intraoperative transeosphageal echocardiogram did not reveal significant enough aortic stenosis to warrant surgical replacement of his valve. please see operative note for details. postoperatively he was taken to the intensive care unit for monitoring. over the next several hours, he awoke neurologically intact and was extubated. aspirin, statin and beta blockade were resumed. on postoperative day one, he was transferred to the step down unit for further recovery. he was gently diuresed towards his preoperative weight. the physical therapy service was consulted for assistance with his strength and mobility. the patient did develop atrial fibrillation and was treated with iv amiodarone. he converted to sinus rhythm thereafter. chest tubes and pacing wires were discontinued without complication. he remained in sinus rhythm and his metoprolol was changed to atenolol as preoperatively. his diuretics will be continued at discharge for a week to get him to his preop weight. he was ready for discharge and was transferred to a rehabilitation facility before eventual discharge to home. he will be kept on warfarin for the paroxysmal atrial fibrillation he had postop. the goal inr is 2 to 2.5. he received 5 mg of coumadin on and will receive 5 mg today (). the duration of this will be determined by his cardiologist. medications on admission: simvastatin
