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 attending: addendum: np was called to patient's room on day of discharge due to dizziness while showering. as patient was being held sitting up in the bathroom he became unresponsive and stopped breathing with no pulse. code was called and compressions were initiated. after ~ 6 compressions, patient regained consciousness, then became unresponsive once again had 5 subsequent compressions. he once again regained consciousness and bp systolic was in the 70's. he remained hemodynamically stable but dizzy with sitting up. echo done showed ef 30% (unchanged) and no pericaridal effusion. he was transferred to cvicu. the following day he was hypotensive and lightheaded after receiving coreg, hctz and lisinopril and these were titrated down. he was transferred back to the floor. his coreg and lisinopril were gradually decreased and then stopped due to hypotension and lightheadedness after taking medications, especially coreg . per dr , he is to go home on no antihypertensives, including no ace-i, due to hypotension. follow up caridology appointment in 1 week for titration/reinstituion of medications. he continued to on anticoagulation for mechanical avr with inr 2.5-3.5 goal. on the day of discharge he was hemodynamically stable with bp 118/78 with no symptoms of dizziness. he was be discharged home in stable condition with visiting nurse services. inr 2.6 on day of discharge. major surgical or invasive procedure: aortic valve replacement (mechanical st. 23-mm) past medical history: colon ca s/p anastomotic reconstruction followed by chemotherapy/radiation port-a-cath discontinued in erectile dysfunction fecal stress incontinence chronic right sided sinus pressure decreased auditory acuity tonsillectomy colon resection as above pertinent results: 06:00am blood wbc-6.2 rbc-4.01* hgb-12.1* hct-34.3* mcv-86 mch-30.0 mchc-35.2* rdw-13.3 plt ct-301 04:20am blood wbc-8.1 rbc-4.37* hgb-13.3* hct-38.2* mcv-88 mch-30.5 mchc-34.9 rdw-13.4 plt ct-280 05:14am blood wbc-6.6 rbc-4.11* hgb-12.5* hct-36.0* mcv-88 mch-30.4 mchc-34.7 rdw-13.6 plt ct-230 09:38am blood wbc-5.9 rbc-4.02* hgb-12.4* hct-35.3* mcv-88 mch-30.9 mchc-35.2* rdw-13.6 plt ct-242 06:00am blood glucose-92 urean-23* creat-1.1 na-142 k-4.2 cl-106 hco3-28 angap-12 04:20am blood glucose-108* urean-19 creat-1.0 na-142 k-4.3 cl-105 hco3-26 angap-15 05:14am blood glucose-102* urean-18 creat-1.0 na-140 k-4.0 cl-105 hco3-26 angap-13 09:38am blood glucose-111* urean-17 creat-1.1 na-141 k-4.0 cl-107 hco3-24 angap-14 tte left atrium - long axis dimension: *5.3 cm <= 4.0 cm left ventricle - septal wall thickness: *1.2 cm 0.6 - 1.1 cm left ventricle - inferolateral thickness: *1.2 cm 0.6 - 1.1 cm left ventricle - diastolic dimension: *5.8 cm <= 5.6 cm left ventricle - systolic dimension: 5.3 cm left ventricle - fractional shortening: *0.09 >= 0.29 left ventricle - ejection fraction: 30% >= 55% aorta - sinus level: 3.4 cm <= 3.6 cm aortic valve - peak velocity: *2.3 m/sec <= 2.0 m/sec aortic valve - peak gradient: *23 mm hg < 20 mm hg aortic valve - mean gradient: 11 mm hg mitral valve - e wave: 0.7 m/sec mitral valve - a wave: 0.8 m/sec mitral valve - e/a ratio: 0.88 mitral valve - e wave deceleration time: *98 ms 140-250 ms findings left atrium: moderate la enlargement. left ventricle: mild symmetric lvh. mildly dilated lv cavity. depressed lvef. no resting lvot gradient. right ventricle: rv not well seen. aorta: normal aortic diameter at the sinus level. aortic valve: bileaflet aortic valve prosthesis (avr). avr well seated, normal leaflet/disc motion and transvalvular gradients. mitral valve: normal mitral valve leaflets with trivial mr. no mvp. normal mitral valve supporting structures. no ms. tricuspid valve: normal tricuspid valve leaflets with trivial tr. normal tricuspid valve supporting structures. no ts. pericardium: no pericardial effusion. conclusions the left atrium is moderately dilated. there is mild symmetric left ventricular hypertrophy. the left ventricular cavity is mildly dilated. lv systolic function appears depressed (ejection fraction 30 percent), at least partly due to marked mechanical dyssynchrony (pacing vs left bundle branch block). a bileaflet aortic valve prosthesis is present. the aortic valve prosthesis appears well seated, with normal leaflet/disc motion and transvalvular gradients. the mitral valve appears structurally normal with trivial mitral regurgitation. there is no mitral valve prolapse. there is no pericardial effusion. discharge medications: 1. outpatient lab work labs: pt/inr for coumadin ??????
