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: iodine / heparin agents attending: addendum: the patient experienced a drop in oxygen saturation when ambulating with physical therapy and was kept in-house for further work-up. as both his cxr and vq scan were normal, a pulmonary embolus was less likely to be the cause and a cardiac etiology was pursued. results are as follows: the left atrium is dilated. there is mild symmetric left ventricular hypertrophy. the left ventricular cavity is unusually small. overall left ventricular systolic function is normal (lvef>55%). the right ventricular cavity is unusually small. right ventricular systolic function is normal. the ascending aorta is mildly dilated. the aortic valve leaflets (3) appear structurally normal with good leaflet excursion and no aortic regurgitation. the mitral valve appears structurally normal with trivial mitral regurgitation. there is borderline pulmonary artery systolic hypertension. there is no pericardial effusion. compared with the prior study (images reviewed) of , biventricular cavity size is now smaller consistent with volume depletion. seen by pulmonology on for evaluation of oxygen desaturation with activity. consistent with pulmonary hypertension, or may be hepatopulmonary shunt. patient will be followed up by pulmonary, appointment has been made. discharge disposition: extended care md procedure: enteral infusion of concentrated nutritional substances hemodialysis venous catheterization for renal dialysis percutaneous abdominal drainage other transplant of liver other kidney transplantation transfusion of packed cells transfusion of platelets other operations on lacrimal gland transplant from cadaver diagnoses: hyperpotassemia acute kidney failure with lesion of tubular necrosis urinary tract infection, site not specified congestive heart failure, unspecified unspecified essential hypertension diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled acute and subacute necrosis of liver alcoholic cirrhosis of liver hepatorenal syndrome unspecified protein-calorie malnutrition other and unspecified alcohol dependence, in remission portal hypertension long-term (current) use of insulin intestinal infection due to clostridium difficile pressure ulcer, lower back anticoagulants causing adverse effects in therapeutic use hepatic encephalopathy dehydration esophageal varices in diseases classified elsewhere, without mention of bleeding unspecified hereditary and idiopathic peripheral neuropathy polyuria abnormal involuntary movements pain in limb 

Answer: The patient is high likely exposed to
