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: past medical history: 1. coronary artery disease: a) the patient had coronary artery bypass grafting with a saphenous vein graft to the left anterior descending artery, a saphenous vein graft to the first obtuse marginal artery, a saphenous vein graft to the third obtuse marginal artery and a saphenous vein graft to the right coronary artery. b) he had re-do coronary artery bypass grafting in with a saphenous vein graft to the left anterior descending artery with no bypass grafts to total occlusions of right coronary artery and obtuse marginal artery grafts. c) in , the patient had a stent of the saphenous vein graft to the left anterior descending artery with a cardiac catheterization showing a left ventricular end diastolic pressure of 17, an ejection fraction of 42% and mid inferior akinesis and anterolateral akinesis/hypokinesis. d) in , the patient had a percutaneous transluminal coronary angioplasty of a saphenous vein graft to the left anterior descending artery with a left ventricular end diastolic pressure of 19. 2. hypercholesterolemia. 3. hypertension. 4. chronic renal insufficiency with a baseline creatinine of 1.9. 5. hernia repair. medications

no known drug allergies. history of present illness: the patient was doing well post percutaneous transluminal coronary angioplasty in . on , he developed back pain while sitting. this involved radiation to his left arm and also some retrosternal chest pain. he also described some slight shortness of breath with nausea and diaphoresis. this episode of chest pain was not initially relieved with sublingual nitroglycerin and the patient presented to . at , the patient was found to have no acute electrocardiogram changes and laboratory investigation showed a cbc with a white blood cell count of 10.7, a hematocrit of 36.6, a platelet count of 291 and a chem 7 which was within normal limits with a bun of 50 and a creatinine of 1.9. his ck, mb and troponin i were noted to be 64, 2.6 and 0.2. his second set of enzymes were also normal. the patient was admitted and his chest pain was treated with nitroglycerin and heparin drips. he was also noted to have an asymptomatic run of ventricular tachycardia of 27 beats without any hemodynamic compromise. the patient was started on a lidocaine infusion at that time. the patient was transferred to on and was taken straight to the cardiac catheterization laboratory. there, he was found to have a cardiac output and cardiac index of 3.1 and 1.8 respectively. his right ventricular end diastolic pressure was 16 and his pulmonary artery pressures were 48/28 with a mean of 39. his wedge pressure was noted to be 29 and his mixed venous oxygen saturation was 42. no left ventricular angiography was done. examination of the coronary arteries showed a right dominant system with a normal left main coronary artery. there was a 99% lesion at the first obtuse marginal artery and a 100% lesion at the second obtuse marginal artery. his posterolateral ventricular branch was noted to be occluded at 30%. the right coronary artery, which had a previous known occlusion, was not injected. the patient's saphenous vein graft to left anterior descending artery stent was found to be 98% occluded and the patient underwent balloon percutaneous transluminal coronary angioplasty and subsequent brachytherapy with a residual occlusion of 10%. social history: the patient denied any history of tobacco use. he consumed alcohol socially and currently lived alone without support. the patient was capable of doing his own shopping, cooking, cleaning and driving. he did have a health care proxy by the name of , who resided at 74 in . family history: the family history was noncontributory. physical examination: on examination, the patient was in no apparent distress with vital signs showing a temperature of 96.9??????f, a blood pressure of 138/63, a heart rate of 87, a respiratory rate of 20 and an oxygen saturation of 96% on a nonrebreather mask. the neurological examination was unremarkable. the patient was awake, alert and oriented times three. on head and neck examination, the pupils were equal and reactive to light. the extraocular movements were intact. the oropharynx was moist. on cardiovascular examination, the patient's jugular venous pressure was 8-10 cm above the sternal angle. he had a normal s1 and s2 with an s3 and s4. he did not have any audible murmurs. the respiratory examination showed diffuse crackles half way up his chest bilaterally with no wheezes. the abdominal examination was unremarkable. the extremities showed palpable bilateral dorsalis pedis pulses with no edema. he had a right groin pulmonary artery catheter line in place and his arterial sheath site was clean, dry and intact with no bruit or hematoma. laboratory data: the patient's cardiac care unit laboratory values showed a white blood cell count of 14,200, hematocrit of 27.6 and platelet count of 211,000. chem 7 showed a sodium of 129, potassium of 4.1, chloride of 97, bicarbonate of 18, bun of 46, creatinine of 2.1 and glucose of 217. ck was 555, calcium was 9.0 and magnesium was 1.6. arterial blood gases showed a ph of 7.33, a pco2 of 29 and a po2 of 90. electrocardiogram: the patient's electrocardiogram on showed him to be in sinus rhythm at 60 with a prolonged p-r interval, a normal p wave and a qrs axis of -60 to -90. he also had a right bundle branch block with a left anterior hemiblock. he had q waves noted in leads iii and avf. he also had some premature ventricular contractions. there were t wave inversions in leads v1 to v4, which appeared unchanged from his electrocardiogram from . radiology data: the patient's chest x-ray showed significant pulmonary vascular redistribution cephalad. hospital course: following cardiac catheterization, the patient was continued on plavix and received aggressive diuresis for his elevated pulmonary capillary wedge pressure. on , the patient was noted to have continued runs of nonsustained ventricular tachycardia and an echocardiogram was done, which showed the patient to have a moderately depressed left ventricular function with 1+ aortic insufficiency, 2+ mitral regurgitation and 1+ tricuspid regurgitation. he also was noted to have inferior and inferoseptal hypokinesis. the pulmonary artery catheter was removed along with the introducer on that day. on , the patient was noted to be in atrial bigeminy in the morning and also continued to have short runs of nonsustained ventricular tachycardia of three to four beats. the patient continued with his intravenous diuresis with 80 mg of lasix q.d. and was subsequently transferred to the floor. on , the electrophysiology department was informally consulted and the patient's metoprolol dose was increased. the patient's rhythm continued to be monitored. on , the patient was in stable condition with adequate diuresis. his nonsustained ventricular tachycardia continued to improve and the patient continued to show no further episodes of nonsustained ventricular tachycardia. the patient was discharged home on in stable condition. discharge
