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: penicillins / vancomycin attending: chief complaint: abdominal pain, dizziness, nausea, malaise x4 days major surgical or invasive procedure: egd history of present illness: hpi: patient is a 76 y/o m hx of cad s/p cabg w/ a four day hx of dizziness, nausea and constipation, w/ gen malaise, poor po intake over the past few weeks. recent episoded of diarrhea followed by constipation over the past week. poor po intake, because angina worse with eating, has led to avoidance of food. patient has severe angina that is refractory to maximal medical management per recent notes in omr, 2-3 episodes per day per patient. denies syncope or claudication. pt states angina is not becoming more frequent or severe. angina is relieved by slntg . originally presented to hospital w/ c/o lightheadedness, cp x2 episodes similar to angina, which was relieved by ntg. at osh sbp in 80s then drop to 60s. responded to sbp in 100s after given ntg. noted to be guaic positive. patient hypotensive there but responed to nitro and fluids. transferred to for further management. patient was hypotensive to 60s responded to several fluid boluses, w/ bp responding to sbp 137, then having cp, that was relieved w/ ntg sublingual. transferred to micu given hypotension . micu course: patient remained stable in micu. no episodes of hypotension. no use of pressors. cardiac enzymes negative x3. no ischemic changes on ecg. tte showed worsening as, now severe. past medical history: cad s/p cabg dm bradycardia s/p dual chamber bph total knee replacement arthritis social history: sh: lives alone, has 2 daughters in the area. retired fine arts teacher, current theater clinic. quit tob 45 yers abo no etoh family history: fh: dm 75 died' mom mi dad mi pertinent results: p-mibi: mild, fixed perfusion defect involving the basilar portion of the inferior wall, unchanged from prior study. 2. mild left ventricular enlargement with calculated ef of 67%. . tte: conclusions: the left atrium is mildly dilated. the estimated right atrial pressure is mmhg. there is mild symmetric left ventricular hypertrophy with normal cavity size and systolic function (lvef>55%). right ventricular chamber size and free wall motion are normal. the aortic valve leaflets are moderately thickened. there is severe aortic valve stenosis (area 0.7cm2). mild (1+) aortic regurgitation is seen. the mitral valve leaflets are structurally normal. an eccentric, anteriorly directed jet of mild (1+) mitral regurgitation is seen. there is mild pulmonary artery systolic hypertension. there is no pericardial effusion. . ekg: sinus bradycardia ventricular pacer spikes in pattern of pseudofusion complexes suggested first degree a-v delay intraventricular conduction delay - probably left bundle branch block since previous tracing of , probably no significant change . cta: abdomen to evaluate for ? mesenteric ischemia impression: altherosclerotic disease involving aorta and vessels of major tributaries. however there is no focal stenosis or post-stenotic dilatation of any of the vessels, all vessels are patent. no secondary signs to suggest mesenteric ischemia. . egd: gastric and duodenal erosions. gastric ulcer. biopsy taken. brief hospital course: briefly this is a 76m with cad s/p 4vcabg presenting with poor po intake, 30 lb weight loss, abdominal discomfort and angina found to be hypotensive, admitted initiallo to micu for monitoring and resucsitation. . 1. hypotension: bp improved with fluids. tte showed severe as, which in a volume depleted person who is pre-load dependent was thought to be the likely etiology of pt's hypotension. on date of discharge pt's bp is stable and he has tolerated re-initiation of home antihypertensives. . 2. cad: with chronic stable angina that is refractory to maximal medical therapy per outpatient cardiology notes. ruled out with ces, ekg. likely etiology for angina is severe as. . 3. as. pt was seen by cardiothoracic surgery who recommended a full pre-operative work-up in anticipation of avr with possible cabg: including cardiac catheterization, and gi consult. pt received part of work up in house including gi consult and b/l carotid ultrasounds. pt will return in ~2 weeks for elective outpatient catheterization and will be in touch with ct surgery regarding bypass surgery scheduling and expectations. . 4. abdominal discomfort:pt presented with symptoms of abdominal pain and angina with eating. he also was guaiac positive and anemic. of note pt had recently been incompletely treated for an assumed h. pylori infection. he had received 2 weeks of a three week course of antibiotics before self discontinuing the medications due to diarrhea. pt had a history of a recent colonoscopy in which was significant only for grade 2 internal hemorrhoids. pt underwent an egd on which showed gastric and duodenal erosions and a gastric ulcer. pt continued on ppi. biopsy taken, will return in a week, if remains h. pylori positive, pt's pcp will contact the pt re: starting prevpac. pt also underwent a cta of the abdomen to evaluate for mesenteric ischemia in light of his symptoms of post-prandial pain, this study showed no evidence for any occluded bowel vessels. . 5. diabetes: riss and metformin continued, metformin held for 48 hours after administration of cta dye load. . 6. bph: pt initially experienced urinary retention requiring foley which was shortly thereafter discontinued, on the day prior to discharge pt again experirenced an episode of retention requiring foley replacement, this was again weaned prior to leaving the hospital. pt continued on proscar and doxazosin. plan to follow up with outpatient urology if retention remains an active issue. pt initally emperically treated for uti with cipro, whis was d/c'd when culture results returned negative. pt will contact his primary care physician . for a follow up appointment within a week after discharge. he will also be following up with cardiothoracic surger regarding completion of pre-op workup including outpatient cardial catheterization, dental clearance, and potential vein mapping. will need repeat egd prior to or given risk of bleeding with surgery/anticoagulation. pt/pcp to follow up egd biopsy results in 1 week post discharge for result of h. pylor test, if postive to complete prevpac treatment. pt to return to dr. for repeat egd in weeks. medications on admission: home meds: medications: atenolol 50mg daily lasix 20mg dialy lisinopril 10mg daily proscar 5mg daily lipitor 10mg daily metformin 500mg
