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: addendum: of note, mr. had episdoes of non-sustained ventricular tacycardia throughout his hospital course of decreasing duration. he remained asymptomatic and hemodynamically during the episodes. electrophysiology was consulted and recommended increasing his lopressor as tolerated. his hear rate was 45-50 at rest with bp 130-140/60. his betablocker was unable to be increased due to bradycardia and his lisinopril was increased for bp control. electrophysiology was not of the opinion that a pacer was indicated at ths time. discharge disposition: extended care facility: life care center of md procedure: extracorporeal circulation auxiliary to open heart surgery (aorto)coronary bypass of one coronary artery open and other replacement of aortic valve with tissue graft diagnoses: coronary atherosclerosis of native coronary artery esophageal reflux acute kidney failure with lesion of tubular necrosis cardiac complications, not elsewhere classified hypertensive chronic kidney disease, unspecified, with chronic kidney disease stage i through stage iv, or unspecified gout, unspecified atrial fibrillation personal history of malignant neoplasm of prostate obstructive chronic bronchitis with (acute) exacerbation aortic valve disorders atrial flutter chronic kidney disease, unspecified paroxysmal ventricular tachycardia other and unspecified hyperlipidemia atrioventricular block, complete surgical operation with anastomosis, bypass, or graft, with natural or artificial tissues used as implant causing abnormal patient reaction, or later complication, without mention of misadventure at time of operation other second degree atrioventricular block 

Answer: The patient is high likely exposed to
