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: fatigue and black stool major surgical or invasive procedure: egd history of present illness: 74 yom w/ h/o htn, hyperlipidemia and prior stroke on asa and plavix presents with fatigue x a few days and black stool x 24 hours. he states that his symptoms began 5 days prior to admission with fatigue and decreased appetite. he states he had poor po intake due to his decreased appetite but also had a mild constant nausea that would worsen with po intake. he complains of fatigue and dyspnea on exertion upon climbing 1 flight of stairs. 1 day pta he had 1 relatively formed very black bowel movement x 1 and felt lightheaded, day of admission this occured again (no lightheadedness though). . he has never had anything like this in the past, no brbpr, no epigastric pain but did have lower abd pain which was a heavy feeling, constant since tuesday. he denies heartburn type symptoms or dysphagia. . no previous ulcers or previous egd. . lbs weight loss over a few months, non intentional, denies fevers chills or night sweats. . of note complains of chest pain day prior to admission occured while seated after helping his son move boxes. sharp l sided chest pain that lasted only seconds, no associated symptoms or radiation. . as above, doe x 1 flight of stairs without orthopnea / pnd or pedal edema. past medical history: hypertension dyslipidemia aortic insufficiency (moderate ) s/p stroke in , presented with speaking difficulties, left arm weakness, facial droop, no residual deficits. arthritis urinary urgency social history: denies tob. no history of alcohol abuse, 1 etoh drink per month. he formerly worked in construction, and reports significant asbestos exposure. family history: there is no family history of premature coronary artery disease or sudden death although mother died of stroke at elderly age. his recently died of "pulmonary thrombosis," had history of bypass. his mother had a cva. physical exam: tmax: 37 ??????c (98.6 ??????f) tcurrent: 36.6 ??????c (97.9 ??????f) hr: 46 (45 - 62) bpm bp: 123/51(76) {101/44(58) - 131/62(78)} mmhg rr: 13 (9 - 20) insp/min spo2: 97% general appearance: well nourished eyes / conjunctiva: perrl head, ears, nose, throat: normocephalic cardiovascular: (pmi normal), (s1: normal), (s2: normal), no(t) s3, no(t) s4, (murmur: systolic) respiratory / chest: (expansion: symmetric), (breath sounds: clear : ) pertinent results: admit labs: =========== 09:40pm blood wbc-6.7 rbc-3.13*# hgb-9.8*# hct-27.7*# mcv-88 mch-31.1 mchc-35.2* rdw-14.1 plt ct-184 01:35am blood hct-24.0* 09:30am blood wbc-5.8 rbc-3.24* hgb-9.9* hct-28.8* mcv-89 mch-30.4 mchc-34.2 rdw-13.2 plt ct-132* 12:47pm blood hct-27.6* 09:40pm blood pt-12.4 ptt-27.3 inr(pt)-1.0 09:40pm blood glucose-106* urean-45* creat-1.2 na-131* k-4.2 cl-95* hco3-28 angap-12 09:30am blood glucose-111* urean-32* creat-1.0 na-137 k-3.9 cl-103 hco3-27 angap-11 09:40pm blood alt-14 ast-18 ck(cpk)-168 alkphos-40 totbili-0.2 09:55pm blood ctropnt-<0.01 09:30am blood ck-mb-4 ctropnt-<0.01 09:30am blood calcium-8.8 phos-3.0 mg-1.9 . egd (): impression: erythema, erosions in the antrum compatible with erosive gastritis two ulcers with a clean base and no vissible vessel or active bleeding were seen in the pyloric channel. otherwise normal egd to third part of the duodenum . ecg () - sinus @48. rbbb. lafb. twi ii/iii/avf . discharge/other labs: ===================== 06:40am blood wbc-7.0 rbc-3.45* hgb-10.8* hct-31.4* mcv-91 mch-31.4 mchc-34.5 rdw-13.7 plt ct-188 08:40am blood hct-29.5* 06:35am blood wbc-6.2 rbc-3.28* hgb-10.3* hct-29.3* mcv-89 mch-31.3 mchc-35.1* rdw-13.6 plt ct-156 06:40am blood glucose-115* urean-17 creat-1.1 na-137 k-4.1 cl-101 hco3-29 angap-11 09:30am blood ck(cpk)-144 09:30am blood ck-mb-4 ctropnt-<0.01 09:55pm blood ctropnt-<0.01 09:40pm blood ck-mb-4 . time taken not noted log-in date/time: 4:28 pm serology/blood chem# m. **final report ** helicobacter pylori antibody test (final ): positive by eia. (reference range-negative). brief hospital course: impression / plan: 74 yom w/ a h/o previous cva (13 years ago) on aspirin and plavix presents with si/sx of upper gi bleed. initially admitted to icu, later transferred to medical floor. . 1. gi bleed 2. acute blood loss anemia patient has black stool x 24 hours with hct drop from 41-> 24. transfused 2 u and stable hct. egd done and showed erosive gastritis. on admission he was on aspirin and plavix, aspirin for previous stroke and had been anticoagulated on coumadin until , this was switched to plavix at that time. bleeding likely in setting of asa/plavix. hct remained stable during the remainder of his hospitalization. he was continued on protonix 40mg and will need to stay on this for at least 8 weeeks. h will need repeat egd in 8 weeks. given his recent use of asa/plavix and the friable mucosa seen, biopsies weren't taken. instead, h. pylori serology was sent. this was pending at the time of discharge, but subsequently returned positive after discharge. the patient will be contact and advised to start on a . . 3. chest pain patient has had occasional chest pain in the past, most recently day prior to admission. in he was admitted for romi, ruled out for mi and underwent an echo w/o wma and a stress mibi without any chest pain, went 8.5 mets, uninterpretable ekgs and normal nuclear imaging. ruled out for mi during this admission. remained chest pain free. twi seen on ecg was also present on ecg in . suspect initial ecg on this admission may have been pseudonormalization in setting of bleed. given patient ruled for mi and without cardiac symptoms, did not repeat cardiac enzymes. repeat ecg prior to discharge similar to previous studies. would strongly consider outpatient stress and echo to further evaluate ecg abnormalities. . 4. h/o cva no residual effects at present. was on aspirin due to stroke 13 years prior and was started on coumadin as an "aspirin failure." 1 month ago his coumadin was stopped and plavix started in its place. no history of having a cardiac or peripheral stent placed. this seems to be purely for stroke prevention. asa and plavix were stopped. outpatient cardiologist was contact. restart asa at 81mg in days . 5. hypertension bp stable. bp meds held during hospitalization, but to be restarted on discharge. . 6. bradycardia sinus. has been present at least since beginning of this year (noted on previous cardiology visits). patient not on nodal blocking agents. does have other conduction abnormalities (rbbb, lafb). does not report any symptoms of lightheadedness or dizziness. no palpitations or heart pounding. was monitored on telemetry and had heart rates in the 40s-50s without symptoms. occasionally decreased to high 30s while sleeping. has been set up with close outpatient cardiology follow up. if symptomatic, consider ppm. . 7. hyperlipidemia he was continued on a statin. medications on admission: aspirin 325mg daily plavix 75mg daily hctz 25mg daily lisinopril 20mg daily lipitor 10mg daily tylenol prn discharge medications: 1. aspirin ec 81 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po once a

blood loss anemia sinus bradycardia hypertension history of cva discharge condition: afebrile, vital signs and hematocrit stable. no further melena. discharge instructions: you had bleeding in your stomach. this was likely made worse by taking aspirin and plavix. both of these medications have been stopped. you can restart the aspirin (at 81mg instead of 325mg) on monday (). you should stay off the plavix until directed otherwise. . you will need to remain on a medication called protonix for at least 8 weeks. blood tests were sent to look for an infection (h. pylori) that can make ulcers
