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: this is a 64-year-old male with a history of coronary artery disease and substernal chest pain who recently had an increase in exacerbation. saw his primary medical doctor who did a cardiac evaluation consisting of catheterization which showed left anterior descending artery 90%, om2 80%, right coronary artery was stented, ejection fraction was not done. there is no report of an echocardiogram. past medical history: 1. cerebrovascular accident times two with left hemiparesis. 2. history of inferior myocardial infarction. 3. history of hypertension. 4. history of increased cholesterol. 5. gastroesophageal reflux disease. 6. diverticulosis. 7. history of esophagus. 8. hiatal hernia. 9. dupuytren's contracture. physical examination on presentation: head, eyes, ears, nose, and throat revealed no bruits. lungs were clear. cardiovascular with a regular rate and rhythm, with normal first heart sound and second heart sound. left hemiparesis. extremities with no edema. ho course: the patient was admitted to the cardiothoracic surgery service. he was seen by dr. and consented for cardiac surgery. on , the patient was taken to the operating room and underwent coronary artery bypass graft surgery times four; left internal mammary artery to left anterior descending artery, saphenous vein graft to diagonal, saphenous vein graft to first obtuse marginal, saphenous vein graft to second obtuse marginal. the patient tolerated the procedure well and was transferred to the cardiothoracic intensive care unit in satisfactory and hemodynamically stable condition. postoperatively, the patient was doing well. he had his chest tubes discontinued. his lines were discontinued. his catheters were discontinued. he was up and walking with physical therapy. on , the patient was noted to be in rapid atrial fibrillation at 160, and intravenous bolus of lopressor was given, and he was started on amiodarone. he also received potassium. he converted to normal sinus rhythm with all of those interventions. the patient was continued on his amiodarone. the patient was now being seen by physical therapy as discharge was now being considered. on (which was cardiac surgery postoperative day four), the patient again developed rapid atrial fibrillation. he then converted on his own to sinus rhythm. his pacemaker wires were discontinued at this point; as he continued to be treated with amiodarone, we wanted to make sure that there were no means to irritate his heart if he got converted and stayed converted, so his wires were discontinued. lopressor was increased, and he was doing well. the patient remained in normal sinus rhythm, and on , the patient was in normal sinus rhythm. he was on his amiodarone. he was hemodynamically stable. physical therapy thought he was safe enough to go home. discharge status: the patient was then discharged home on postoperative day six (). condition at discharge: condition on discharge was good. die instructions: follow up with dr. in four weeks. he was to follow up with his private cardiologist in two weeks. he was to take his discharge medications as prescribed. he was to do no heavy lifting or driving until that time. discharge diagnoses: 1. status post coronary artery bypass graft surgery. 2. history of inferior myocardial infarction. 3. history of coronary artery disease. 4. hypertension. 5. increased cholesterol. 6. status post cerebrovascular accident times two with left hemiparesis. 7. gastroesophageal reflux disease. 8. diverticulosis. 9. esophagus. 10. hiatal hernia. 11. dupuytren's contracture. , m.d. dictated by: medquist36 procedure: (aorto)coronary bypass of three coronary arteries single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery diagnoses: coronary atherosclerosis of native coronary artery unspecified essential hypertension atrial fibrillation late effects of cerebrovascular disease, hemiplegia affecting unspecified side 

Answer: The patient is high likely exposed to
