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: this is a 53 year old male patient with known coronary artery disease and chest pain ten years ago with catheterization and percutaneous transluminal coronary angioplasty. he has had five catheterizations since that time. more recently he has had episodes with chest pain, now severely affecting his quality of life. he has a strong family history of aortic dissection and early cardiac death. he has a long history of heart murmur with bicuspid aortic valve. he complains also of increased shortness of breath, fatigue even at rest, diaphoresis, nausea and presyncopal episodes. cardiac catheterization on , showed left main 20 percent lesion, left anterior descending coronary artery 20 percent lesion, left circumflex and right coronary artery normal, ejection fraction 55 percent, no mitral regurgitation, no aortic insufficiency, moderately dilated aortic root. echocardiogram showed trace aortic insufficiency, trace mitral regurgitation, 4.1 centimeter ascending aorta with an ejection fraction of 65 percent and mild left ventricular hypertrophy. past medical history: coronary artery disease with percutaneous transluminal coronary angioplasty of left anterior descending coronary artery in . hypertension. hyperlipidemia. liver cyst. gastroesophageal reflux disease. thoracolumbar degenerative disc disease. past surgical history: right leg cyst removal. medications on admission: 1. lipitor 20 mg once daily. 2. lisinopril 2.5 mg once daily. 3. protonix 40 mg once daily. 4. atenolol 12.5 mg once daily. 5. diltiazem 120 mg once daily. 6. aspirin 81 mg once daily. allergies: no known drug allergies. physical examination: vital signs revealed heart rate 76 beats per minute and regular, blood pressure right 142/88, left 128/84, height five feet eight inches tall, weight 185 pounds. in general, a stalky young man with slight shortness of breath on examination. skin - no obvious lesions. head, eyes, ears, nose and throat examination - the pupils are equal, round and reactive to light and accommodation. extraocular movements are intact. anicteric, not injected. neck - no jugular venous distention, no bruits. chest is clear to auscultation bilaterally. the heart is regular rate and rhythm, s1 and s2, faint i/vi systolic ejection murmur without radiation. the abdomen is soft, nontender, nondistended, positive bowel sounds, no costovertebral angle tenderness. extremities are warm, well perfused. varicosities in the right posterior calf. neurologically, cranial nerves ii through xii are grossly intact. nonfocal examination. excellent strength in all four extremities. hospital course: the patient was admitted on , with diagnosis of dilated ascending aorta and bicuspid aortic valve. he underwent a supracoronary ascending aortic graft with a 24 millimeter gel weave graft and a resuspension of the aortic valve under general anesthesia. cross clamp time was 53 minutes. cardiopulmonary bypass time was 70 minutes. he was transferred out of the operating room to the cardiac surgery recovery unit in normal sinus rhythm with a rate of 84 and propofol drip with a mean arterial pressure of 70, cvp 10, pat 13. postoperative day number one was uneventful with a small amount of neo-synephrine continued for blood pressure support. he was extubated also on postoperative day number one. on postoperative day number two, his hematocrit was down to 21. he was transfused two units of packed red blood cells with increase in hematocrit to 27.3. he was transferred to the inpatient unit on postoperative day number two. he continued without any events on postoperative day number three. his atrial and ventricular pacing wires were discontinued. he had a brief episode of supraventricular tachycardia that resolved spontaneously and did not recur. his mediastinal chest tubes were also discontinued on postoperative day number three. he was followed by physical therapy throughout his hospital course and was found to be safe for home on . he was discharged home with visiting nurse at that time. condition on discharge: on physical examination, his lungs were clear to auscultation. cardiovascular examination - regular rate and rhythm, s1 and s2, no murmurs, rubs or gallops. incisions are clean, dry and intact. sternum is stable. abdomen reveals positive bowel sounds, positive bowel movement. laboratories on discharge revealed white blood cell count 8.6, hematocrit 27.5, platelet count 168,000. sodium 139, potassium 4.1, chloride 103, bicarbonate 29, blood urea nitrogen 13, creatinine 0.9, glucose 110. chest x-ray on the date of discharge showed small bilateral pleural effusions, left greater than right, patchy atelectasis within the left base, no pneumothorax. discharge status: to home with . discharge diagnoses: coronary artery disease, status post percutaneous transluminal coronary angioplasty of the left anterior descending coronary artery in . hypertension. elevated cholesterol. status post ascending aortic graft and resuspension of the aortic valve. medications on discharge: 1. colace 100 mg p.o. twice a day. 2. aspirin 325 mg p.o. once daily. 3. percocet one to two tablets p.o. q4-6hours p.r.n. 4. lipitor 20 mg p.o. once daily. 5. protonix 40 mg p.o. once daily. 6. ferrous sulfate 325 mg p.o. once daily. 7. vitamin c 500 mg p.o. twice a day. 8. ibuprofen 600 mg p.o. q6hours p.r.n. 9. lopressor 50 mg p.o. twice a day. 10. lasix 20 mg p.o. once daily for seven days. 11. potassium chloride 20 meq p.o. once daily for seven days. fop: appointment with dr. in one to two weeks. appointment with dr. in four weeks. , m.d. procedure: venous catheterization, not elsewhere classified extracorporeal circulation auxiliary to open heart surgery resection of vessel with replacement, thoracic vessels transfusion of packed cells operations on other structures adjacent to valves of heart diagnoses: esophageal reflux unspecified essential hypertension thoracic aneurysm without mention of rupture percutaneous transluminal coronary angioplasty status other and unspecified hyperlipidemia family history of ischemic heart disease congenital insufficiency of aortic valve
