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: on the patient exercised for five minutes protocol and achieved 88 percent of his age-predicted heart rate. an electrocardiogram was significant for 6-mm st segment depressions in leads ii, iii, avf, v1, and v4 through v6. frequent premature ventricular contractions were noted. nuclear imaging revealed a dilated left ventricular cavity with stress and mild inferoapical reversible defects. the ejection fraction was 59 percent with no wall motion abnormalities. as a result of this, the patient was referred to the cardiac surgery service for a coronary artery bypass grafting. past medical history: a cerebrovascular accident in - with residual left hand swelling. a myocardial infarction in ; status post ppca of the right coronary artery in . mitral regurgitation. carotid artery disease. social history: right carotid endarterectomy and appendectomy. allergies: the patient has no known drug allergies. medications at home: 1. lisinopril/hydrochlorothiazide 20/25 mg by mouth every day 2. atenolol 100 mg by mouth once per day. 3. lipitor 20 mg by mouth once per day. 4. aspirin 81 mg by mouth once per day. physical examination on presentation: the patient is a 73- year-old gentleman in no acute distress. head, eyes, ears, nose, and throat examination revealed the pupils were equal, round, and reactive to light and accommodation. the extraocular movements were intact. the oropharynx was benign. neck examination revealed the trachea was midline. pulmonary examination revealed the lungs were clear to auscultation bilaterally. cardiovascular examination revealed a regular rate and rhythm. the abdomen was soft, nontender, and nondistended. there were no masses. extremities revealed no cyanosis and no edema. neurologically, the patient was alert and oriented times three. summary of hospital course: the patient was admitted on and taken to the operating room where he underwent coronary artery bypass grafting times two. the patient tolerated the procedure well and received novolin products in the operating room and was admitted the cardiac surgery recovery room after his procedure. the patient was extubated the following day and transferred to the floor. on his pacemaker wires were discontinued. discharge disposition: he was seen by physical therapy who cleared him to go home. condition on discharge: he was discharged on in good condition. discharge diagnoses: status post coronary artery bypass grafting on . status post cerebrovascular accident. status post myocardial infarction. mitral regurgitation. carotid disease. status post right carotid endarterectomy. status post appendectomy. medications on discharge: 1. aspirin 81-mg tablets one tablet by mouth once per day. 2. acetaminophen 325-mg tablets two tablets by mouth q.4h. as needed (for pain). 3. clopidogrel bisulfate 75-mg tablet by mouth once per day (for three months). 4. atorvastatin calcium 20-mg tablets one tablet by mouth once per day. 5. furosemide 20-mg tablets one tablet by mouth once per day (for five days). 6. atenolol 100-mg tablets one tablet by mouth once per day. discharge follow-up plans: the patient was instructed to make an appointment with dr. in five to six weeks. the patient was also instructed to make a follow-up appointment with is cardiologist. , procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery insertion of endotracheal tube (aorto)coronary bypass of one coronary artery arterial catheterization pulmonary artery wedge monitoring central venous pressure monitoring diagnoses: coronary atherosclerosis of native coronary artery mitral valve disorders percutaneous transluminal coronary angioplasty status old myocardial infarction 

Answer: The patient is high likely exposed to
