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 was a 76 year old male with increasing shortness of breath and paroxysmal nocturnal dyspnea for a week who was in an outside hospital until one month ago where he noted increasing shortness of breath. the patient also notes an irregular heartbeat. the patient reports increasing paroxysmal nocturnal dyspnea over the past week and increasing shortness of breath and increasing pedal edema without any chest pain. the patient was seen by his primary care physician and dr. and was admitted from home for heparin, transesophageal echocardiogram and cardioversion on monday. past medical history: new onset atrial fibrillation, hypertension, coronary artery disease status post coronary artery bypass graft in , chronic renal insufficiency, congestive heart failure with an ejection fraction of 38%. gout. automatic implanted cardioverter defibrillator with biventricular pacing. hypercholesterolemia. status post left carotid endarterectomy. status post left renal stent. allergies: no known drug allergies. medications: terazosin 4 a day, cozaar 50 a day, coreg 12.5 b.i.d., allopurinol 100 a day, aspirin 81 q. day, lasix 80 b.i.d., lipitor 40 q. day, isosorbide 60 am, 30 pm and senna 6 q.h.s. social history: the patient has a 25 year two pack per day smoking history with occasional alcohol and intravenous drug abuse. physical examination: vital signs: 110/80, 66, 20 and 95% on room air. general: obese male sitting in bed in no apparent distress. neck: 12 cm jugulovenous distension at 90 degrees. heart: irregularly irregular, no murmurs or gallops. lungs: clear to auscultation bilaterally, no rales. abdomen: obese, positive bowel sounds, distended. extremities: 2+ pedal edema bilaterally. laboratory data: pertinent laboratory data revealed echocardiogram on showed left ventricular ejection fraction of 30%, 2+ mitral regurgitation which may be underestimated with a biventricular pacemaker. electrocardiogram and chest x-ray were pending. hospital course: 1. cardiovascular - coronary-wise, the patient has coronary artery disease, status post coronary artery bypass graft in with an occluded saphenous vein graft, right coronary artery. the patient was continued on aspirin and lipitor. the patient initially was hypotensive and his beta blocker was held until his blood pressure continued to rise. the patient was ruled out for myocardial infarction with three negative cardiac enzymes and was on a heparin drip at that time. pump, congestive heart failure with ejection fraction of 38%. transesophageal echocardiogram showed ejection fraction of 15% with mitral regurgitation and left bundle branch block. biventricular pacer with implantable cardioverter defibrillator was placed. for his decompensated congestive heart failure the patient was kept on dopamine and dobutamine and all other blood pressure medications were held. the patient was diuresed effectively with a combination of dopamine and dobutamine and lasix. the patient was fully weaned off of the dopamine and dobutamine on , and the patient was then transferred to c-med. the patient continued to diurese with decreasing oxygen requirements, however, the patient was transferred back to the coronary care unit on at which point the patient dr., 12-932 dictated by: medquist36 d: 08:04 t: 08:20 job#: procedure: venous catheterization, not elsewhere classified diagnostic ultrasound of heart other electric countershock of heart insertion of rectal tube irrigation of other indwelling urinary catheter injection or infusion of nesiritide diagnoses: mitral valve disorders acute kidney failure with lesion of tubular necrosis congestive heart failure, unspecified unspecified septicemia atrial fibrillation other specified intestinal obstruction septic shock 

Answer: The patient is high likely exposed to
