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: history of present illness: the patient is a 74-year-old gentleman admitted on from an outside hospital for evaluation of type b aortic dissection and concern for pulmonary embolus. he presented four days ago with chest pain located in the middle of the chest with radiation to his back and also down to his arm. no nausea. no vomiting. the patient was discharged home after a workup for myocardial infarction on . the patient presented again with increased chest pain and had a computed tomography which was notable for type b aortic dissection. his denies any recent fevers or chills. he has had an increased weight loss over the last several months. besides that, no other complaints. past medical history: 1. hypertension. 2. gastroesophageal reflux disease. 3. pancreatitis. 4. a remote history of thyroglossal cyst resection in . 5. he is status post a preserving whipple procedure for periampullary pancreatic carcinoma/ 6. history of upper gastrointestinal bleed in . esophagogastroduodenoscopy in with ulceration. 7. hernia repair in . 8. history of collapsed lung in . family history: no family history of coronary artery disease, hypertension, or diabetes. social history: he quit smoking 35 years ago, but he was smoking one pack per day times 20 years up to then. occasional alcohol use. allergies: demerol. medications on admission: (home medications included) 1. protonix 40 mg by mouth once per day. 2. metoprolol 25 mg by mouth twice per day. 3. lisinopril 5 mg by mouth once per day. 4. flomax by mouth as needed. 5. ambien by mouth as needed. physical examination on presentation: vital signs on examination revealed his temperature was 98.7 degrees fahrenheit, his heart rate was 74, his blood pressure was 116/51 in the left arm, blood pressure in his right arm was 120/58, his oxygen saturation was 95% on room air, and his respiratory rate was 18. in general, in no acute distress and comfortable. head, eyes, ears, nose, and throat examination revealed normocephalic and atraumatic. the neck was supple. pupils were equal, round, and reactive to light and accommodation. cardiovascular examination revealed a regular rate and rhythm. no murmurs, gallops, or rubs. respiratory examination revealed the lungs were clear bilaterally with very mild left lower lobe decreased breath sounds. no crackles or wheezes were noted. the abdomen was soft, nontender, and nondistended. bowel sounds were present. extremity examination revealed the extremities were warm. no clubbing, cyanosis, or edema. pertinent laboratory values on presentation: laboratories on admission revealed white blood cell count was 11.3, his hematocrit was 32.3, and his platelets were 193. inr was 1.3. partial thromboplastin time was 32.2. sodium was 132, potassium was 3.6, chloride was 104, bicarbonate was 23, blood urea nitrogen was 20, creatinine was 0.7, and blood glucose was 95. creatine kinase was 15. troponin was 0.05. magnesium was 1.7, phosphorous was 3.7, and calcium was 8.8. pertinent radiology/imaging: a chest x-ray revealed left lower lobe collapse/consolidation with associated layered pleural effusion. also with right-sided atelectasis. cardiomegaly without evidence of overt heart failure. a computed tomography angiogram showed no pulmonary edema. a left-sided pleural effusion and a dissection which was unchanged when compared to an earlier study. computed tomography showed a type b dissection from the left subclavian to the diaphragm. concise summary of hospital course by issue/system: the patient was admitted to the coronary care unit for evaluation of type b dissection. cardiology surgery and vascular surgery were involved and evaluated the patient and felt that due to repeat x-ray and decreased symptoms, because the patient had remained asymptomatic, there was no need to intervene surgically and to manage the patient medically. the patient was managed medically well with blood pressure control. his blood pressure goal was to keep his blood pressures at 70s which was initially achieved through drips. he was put on an esmolol drip and nitroprusside drip, and he was eventually weaned off the nitroprusside and esmolol drip and put on by mouth medications. on the day prior to discharge, he continued to have some light dizziness, and some of his blood pressure medications were held because his blood pressures were going down to the high 80s. since the day prior to discharge, his blood pressure medications were readjusted and the frequency was changed from 500 mg by mouth twice per day to 300 mg by mouth three times per day to achieve better blood pressure control and without any more evidence of hypotensive episodes. since the patient's tolerated the current regimen change well, also on the day of discharge his lisinopril was withheld the day prior. this was changed from lisinopril twice per day to lisinopril once per day. in terms of his pulmonary status, the patient pleural effusion was most likely secondary to his dissection. per surgery recommendation, no tap was necessary at this time and that it would be reabsorbed over time. he received a magnetic resonance imaging on the day prior to discharge which showed no change from the previous magnetic resonance imaging when he was first admitted in terms of the dissection or the pleural effusion. the patient was to follow up with his primary care physician to actually see the progression of the pleural effusion and the dissection. so far, no change. in terms of renal, no issues on admission. followed regularly throughout the hospital course. the patient's creatinine tolerated the dye doses well without a bump in his creatinine. in terms of gastrointestinal, the patient was maintained on proton pump inhibitor given his history of upper gastrointestinal bleed. in terms of infectious disease, the patient had a one-time temperature increase to 101 on admission; however, he has been afebrile since, and no acute infectious disease issues since admission. in terms of prophylaxis, he was treated with subcutaneous heparin, and protonix, and a bowel regimen. on the day prior to discharge, the patient had multiple bowel movements which he noted to have relieved the mild abdominal pain that he was experiencing. since then, he had no other complaints except mild dizziness which was most likely secondary to his decreased blood pressures. he originally came in blood pressures over 130s to 140s, and now he was in the 110s and 100s to 110s. he was tolerating his by mouth blood pressure medications well. condition at discharge: the patient's condition on discharge was stable. discharge status: the patient was discharged to home with services. discharge instructions/followup: 1. the patient was instructed to call of follow up if he experienced chest pain, shortness of breath, or abdominal pain. 2. the patient was instructed to buy a blood pressure machine for frequent blood pressure checks. the patient was instructed to check his blood pressure about every four hours by himself and by his wife. 3. the patient was instructed to use caution when getting out of bed or if dizzy when getting out of bed. 4. the patient had a follow-up appointment with dr. who is covering for his primary care physician on , , at 2:30. 6. the patient was instructed that it was important to follow up with blood pressure checks and to follow up with dr. . dr. can set up an appointment with cardiology at this time. vascular surgery was , and they noted that there was no reason for them to follow and for him to follow up with his primary care physician. 7. followup with cardiology is important secondary to his dissection. 8. the patient was also scheduled for a magnetic resonance imaging in four weeks to evaluate the progression of dissection. final discharge diagnoses: 1. aortic dissection (type b). 2. hypertension. 3. gastroesophageal reflux disease. 4. history of pancreatitis. 5. history of upper gastrointestinal bleed with ulceration in . 6. history of thyroglossal cyst resection in . 7. status post whipple procedure for pancreatic cancer in . major surgical/invasive procedures: the patient had a computed tomography in with complex type b dissection. no pulmonary embolus was noted. in a magnetic resonance imaging was done which showed thoracic aortic aneurysm with large mural hematoma and separate focal dissection in descending thoracic aorta. a repeat magnetic resonance imaging on to compare versus prior showed no changes. medications on discharge: 1. pantoprazole 40 mg by mouth q.12h. 2. docusate 100 mg by mouth twice per day. 3. hydrochlorothiazide 25 mg by mouth once per day. 4. lisinopril 20 mg by mouth once per day. 5. amlodipine 10 mg by mouth once per day. 6. labetalol 300 mg by mouth three times per day 7. vicodin by mouth as needed (not to exceed three tablets per day and also to hold if sedated or has respiratory distress). discharge disposition: the patient has set up to teach the patient and his wife about medications and also about proper blood pressure measuring and the frequency (which should be about every four hours). discharge activities: out of bed with assistance. discharge diet: cardiac heart-healthy diet taken as tolerated. , m.d. dictated by: medquist36 procedure: arterial catheterization
