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: the patient is a 53 year-old male with known coronary artery disease who came in from an outside hospital. catheterization at 01/02 showed left ventricular ejection fraction of 35 to 40% with an inferior basilar hypokinesis and stenosis 30 to 40% of the lima and 50 to 60% at the lad, 50% of the circumflex and 80% of diagonal. totally occluded rca with collaterals. he was transferred to the on for a cabg on . past medical history: 1. coronary artery disease. 2. acute myocardial infarction in . 3. hypercholesterolemia. 4. hypertension. 5. gerd. 6. schizophrenia treated in the . 7. cervical disc disease. 8. gi bleeding. 9. positive history of h pylori which was untreated. 10. chronic bronchitis. home medications: 1. lopressor 50 milligrams . 2. aspirin 325 milligrams once a day. 3. zantac 150 milligrams . allergies: no known drug allergies. admitting laboratory data: as of chemistry 142, 4.0, 104, 26, 11, 1.3, 99, pt 12.5, inr 1.07. cbc 8.7, 40.9 and 251. hospital course: the patient was admitted to our service preop and started on a heparin drip until the operating room as well as a nitro drip for pain control. the patient was taken to the operating room as scheduled on and admitted to the cardiothoracic intensive care unit postoperatively. he was transferred to the floor on postoperative day one with no acute events. on the floor he had one episode of v tach seven beats, nonsustained. the patient was started on amiodarone. rehab was involved. the patient had a minor desaturation to 80 on room air which is baseline for him. chest x-ray, abg, ekg done at the time showed no ischemic changes and the patient resolved on his own. the patient was asymptomatic during this episode and his respiratory status became better. chest tubes and wires were discontinued on the patient on without incident. chest x-ray showed no pneumothorax postoperatively. the patient's pain control was an issue. his pca was initially discontinued however due to anxiety it was re-instituted. his pca was finally discontinued on . the patient had a strong desire to go home after that. rehab and physical therapy cleared the patient for discharge home. anesthesia pain service was consulted with regard to the patient's disposition and pain control for which they recommended morphine sulfate and ms contin for which the patient is going home on. discharge medications: 1. morphine sulfate immediate release 10 milligrams po q prn. 2. ms contin 30 milligrams po bid. 3. amiodarone 400 milligrams po bid for one week then q day. 4. aspirin 325 milligrams po q day. 5. zantac 150 milligrams po bid. 6. colace 100 milligrams po bid. 7. lasix 20 milligrams po q day times five days. 8. lopressor 25 milligrams . 9. potassium chloride 20 milliequivalents po q day times five days. discharge follow up: the patient is to follow up with his pcp within one to two weeks and he has been explained this. as well as dr. within six weeks. the patient upon discharge has the following physical exam - no jvd, breath sounds present bilaterally. no sternal drainage present. no erythema. leg wound is clean. no discharge. the patient is in fair condition upon discharge and initially in the hospital at least as of now his pain is well controlled. he understands the plan and is being discharged with vna and wound .................... , m.d. dictated by: medquist36 procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery (aorto)coronary bypass of two coronary arteries diagnoses: coronary atherosclerosis of native coronary artery esophageal reflux intermediate coronary syndrome pure hypercholesterolemia unspecified essential hypertension cardiac complications, not elsewhere classified paroxysmal ventricular tachycardia old myocardial infarction 

Answer: The patient is high likely exposed to
