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: abdominal pain with nausea major surgical or invasive procedure: intubation history of present illness: pt is a 68 yo with pmh sig for htn, s/p cardiac catheterization on , who developed abdominal pain and nausea on , presented to osh on and had mra abdomen c/ aortic dissection, transferred to for surgical eval and further medical care past medical history: htn hypothyroidism irritible bowel syndrome diverticulosis social history: lives alone near son and daughter family history: family history of cva physical exam: bp 130's/90's hr 60-70 rr 16 98% ra nad neck without jvd, no thyromegaly cardiac exam with 2/6 sem at aortic space lungs clear abdomen soft nt nd nabs

chloride-100 total co2-31* anion gap-9 . chest ct: ct chest without & with contrast: there has been interval extubation. again identified are bilateral pleural effusions with associated reactive atelectasis, not significantly changed in size or appearance from the previous study. these again measure low (approximately 10 ) in density and show no evidence of hemorrhagic component. fluid is again seen tracking into the fissures, suggesting fluid overload. the descending aortic dissection is again visualized beginning at approximately the t8-9 vertebral body level, and extending downward. the superior aspect of the false lumen between t8 and t11 again demonstrates no enhancement, presumably secondary to thrombus. the , , and celiac are again identified off the true lumen. the kidneys and major abodminal organs show no evidence of ischemia. all of the renal arteries with the exception of the inferior accessory renal artery on the right originate off the true lumen. there is no evidence of interval increase in diameter of the aorta and no evidence of rupture. the dissection is again visualized descending to the level of the external iliac artery on the right. the intimal flap is not clearly seen to extend into the femoral. the liver, spleen, adrenal glands, and kidneys are unremarkable. bone windows: multiple hemangiomas seen within the lumbar vertebrae, otherwise unremarkble osseous structures. ct reconstructions: type b descending aortic dissection extending from above the celiac axis down into the right external iliac artery. stable compared to previous study. impression: 1) stable appearance of type b descending aortic dissection extending from the mid thoracic aorta to the right external iliac artery. perfusion to each of the major arterial branches is again seen. there is no evidence of rupture. 2) stable appearance of bilateral pleural effusions with associated reactive atelectasis. 3) interval extubation. brief hospital course: upon arrival to blood pressure controlled on iv agents, ct scan completed showing aortic dissection from celiac trunck to right external iliac artery. false lumen without obstruction of any aortic branches. medical therapy without surgery, on antihypertensives. on hospital day 3 pt became severely hypotensive and lethargic after receiving dose of antihypertensive nifedipine, requiring intubation. extubated the next day without incident. multiple ct scans over course of hospitalization without change in aortic dissection. blood pressure difficult to control, finally optimized on labaetolol, diltiazem, amlodopine, lisinopril. hospital course complicated by short course (less than 1 hour) of atrial fibrillation which reverted to sinus spontaneously. decision for no anticoagulation due to aortic dissection. pt was stable with systolic blood pressure in 130's at time of discharge. discharge medications: 1. levothyroxine sodium 50 mcg tablet sig: one (1) tablet po daily (daily). 2. aspirin 81 mg tablet, chewable sig: one (1) tablet, chewable po daily (daily). 3. labetalol hcl 200 mg tablet sig: 1.5 tablets po bid (2 times a day). 4. paroxetine hcl 20 mg tablet sig: one (1) tablet po daily (daily). 5. lisinopril 20 mg tablet sig: two (2) tablet po daily (daily). 6. diltiazem hcl 240 mg capsule, sustained release sig: one (1) capsule, sustained release po daily (daily). 7. amlodipine besylate 5 mg tablet sig: one (1) tablet po daily (daily). discharge disposition: home with service facility: vna discharge diagnosis: aortic dissection hypertension discharge condition: stable discharge instructions: please call your doctor or go to the emergency department if you develop chest pain, worsening abdominal pain or shortness of breath. followup instructions: please follow up with dr. within one week. procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours diagnostic ultrasound of heart insertion of
