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: chief complaint: atrial fibrillation with rvr and hypoxemia major surgical or invasive procedure: arterial line placement history of present illness: yo m with pmh of tachy-brady syndrome, mitral regurgitation, and cml, presents with 4-5 days of worsening sob, wt gain, and le edema. he went to his pcp's office today for evaluation and was found to be in rapid afib with hr in the 120s-130s. his pcp did an ekg which confirmed rapid afib, frequent ectopy, and new st depressions. he was felt to have crackles on exam and was given 20mg po lasix. the patient was sent to the ed for further evaluation. . in the ed, his vs were t 97.5, bp 134/37, hr 124, rr 30, sats 93% on ra and 96% on 3l. he was given a full dose asa and 10mg iv diltiazem with no change in his hr. he received a total of 30mg iv diltiazem which eventually brought his hr down to the 90s, but it caused transient hypotension as well, with sbp in the 80s. he was given ivf to improve his bp after the diltiazem. he was also given 30mg po diltiazem to attempt to keep his rate under control. cxr was performed which revealed slightly worsening pulmonary edema and loss of the r heart border, concerning for fluid vs. consolidation. his o2 sats continued to be in the low 90s on 3l so he was bumped up to 6l by nc. he continued to have frequent ectopy and was sent to the floor with his hr still in the 100s. . on arrival to the floor, his hr was in the 110s and his o2 sat was 89% on 5l by nc. he was felt by his rn to be awake, alert and appropriate, asking for food. approximately 1-2 hours after arrival, his sats began to drop to the low 80s on 5l by nc. his o2 sats were difficult to monitor given his frequent ectopy, so he was put on a face mask with 10l o2. he was difficult to arouse and was somewhat disoriented. an abg was performed which was 7.45/33/59, with a lactate of 1.4. he was placed on a nrb with improvement in his sats to the mid 90s. repeat cardiac enzymes were sent. a foley catheter was placed with 400cc of uop immediately. he was given 10mg iv lasix and 5mg iv lopressor. his bp remained in the low 100s and his hr came down to the 90s transiently. repeat cxr showed worsening pulmonary edema, but no frank infiltrate. his mental status did improve somewhat and he was able to converse with me to confirm his symptoms, but he remained tachypneic with a rr in the 30s. . he was transferred to the ccu for closer monitoring. on arrival to ccu his bp was 100/60, hr 100-115, rr 30, pox 95% on nrb. he was mentating well and had no complaints. we discussed intubation and cardiovesion, however pt wanted to wait a few days. given his bl bp is around 100/60 we opted to give another dose of lopressor 5 mg iv. his bp dropped to 87/65. a heparin drip was also started. . of note, the patient was recently admitted in late to early for chest pressure. he was r/o by three sets, a cxr was normal and his cp was thought to be related to anxiety. he continued to have arrythmyia c/w his tachy-brady syndrome. his bb was held and he was seen by dr who did not feel a pcm was indicated at this time. his tsh was slighlty elevated but there was concern over med complicane so his prior dose was resumed. prior to this, in mid , the patient was admitted for syncope and hypoxia and required a micu stay, but no intubation. he had a holter in that showed asymptomatic ectopic atrial beats and 25 isolated vpbs with 6 couplets and two 3-beat runs of vt, rate 110 bpm. past medical history: # mitral regurgitation (1+ mr ) # tachy-brady syndrome # h/o c. diff # rle ulcer # chronic diarrhea # hypothyroidism # cml (t9;22) - intolerant of gleevec (secondary to itch) - being treated with hydrea social history: lives at home with his partner. retired architecture teacher. occasional wine. no ivda. denies tobacco. family history: non-contributory physical exam: vs: t 97.2 bp 87-107/50-70 hr 100-115 rr 28-32 o2 95%nrb gen: awake and alert, oriented to hospital but does not know name of hospital. breathing comfortably on nrb heent: ncat. sclera anicteric. perrl, eomi. conjunctiva were pink, no pallor or cyanosis of the oral mucosa. neck: elevated jvp cv: irregular, +systolic murmur, no rubs/gallops. no thrills, lifts. no s3 or s4. chest: no chest wall deformities resp were unlabored, no accessory muscle use. +crackles to way up. no wheezes. abd: soft, ntnd. no hsm or tenderness. abd aorta not enlarged by palpation. no abdominial bruits. ext: 2+ edema to mid lower leg, with venous stasis changes. 1+ pedal pulses bilat . pulses: right: carotid 2+ femoral 2+ popliteal 2+ dp 1+ pt 1+ left: carotid 2+ femoral 2+ popliteal 2+ dp 1+ pt 1+ pertinent results: ekg demonstrated atrial fibrillation, rate 119, lad, delayed rwp, ivcd, occasional pvcs. brief hospital course: this is a yo m with a pmh of tachy-brady syndrome, mild mitral regurgitation, and cml, who presented with 5 days of sob and was found to be in afib with rvr and chf and borderline bps. the patient was intubated and cardioverted for his atrial fibrillation. he was converted to nsr with frequent ectopy. after extubation, mr. became porgressively short of breath. after discussion with his health care proxy, the decision was made to focus on comfort. m. expired surrounded by his friends and family. . 1) cad: no history of cad. started low dose aspirin. cycled enzymes which were negative. . 2) rhythm: atrial fibrillation with rvr. mr. had a h/o tachy-brady and possible atrial tachycardia versus flutter in old notes. during this stay he did not tolerate the a.fib with rvr and became hypoxic due to a chf exacerbation. he was tranferred to the ccu for respiratory distress. in the ccu the patient was intubated for respiratory distress and was loaded amiodarone and with cardioverted to a nsr with frequent ectopy. . 3) congestive heart failure: mr. had diastolic dysfunction and chf which was probably the result of overall poor cardiac function and his history of tachy-brady and his atrial fibrillation. a repeat echo showed significantly worse cardiac function with an ef of approximately 10%. he was aggresively diuresed. after discussion with his physicians and health care proxy, the decision was made to extubate mr. . he became progressively short of breath. morphine was given to relieve his dyspnea. his hcp made the decision to focus on comfort measures. . 4) cml: mr. was continued on hydroxyurea during his stay. medications on admission: hydrea 2000mg po qd asa 81mg po qd levothyroxine 88mcg po qd discharge medications: expired discharge disposition: expired discharge diagnosis: congestive heart failure atrial fibrillation tachy-brady syndrome hypothyroidism chronic myelogenous leukemia discharge condition: expired discharge instructions: pt. was admitted to the ccu for respiratory distress and chf secondary to atrial fibrillation with rapid ventricular rate. . he expired several hours after extubation. followup instructions: expired procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours venous catheterization, not elsewhere classified diagnostic ultrasound of heart insertion of endotracheal tube arterial catheterization diagnoses: mitral valve disorders congestive heart failure, unspecified unspecified acquired hypothyroidism atrial fibrillation acute on chronic diastolic heart failure sinoatrial node dysfunction chronic myeloid leukemia, without mention of having achieved remission
