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: mr. is a 78 year-old gentleman with a history of inferior myocardial infarction in patient interpreted as indigestion starting at 11 p.m. in the evening prior to admission. the patient describes the pain being constant, increasingly severe. the patient did not come to clinical attention until approximately 12 hours later. he presented to an outside hospital where it was noted that positive creatinine kinase. he was not treated with thrombolytics due to the duration but he had substernal chest pain prior to seeking medical attention. however he continued to have chest pain and therefore was referred to for emergent angioplasty. during the course of his evaluation at the outside hospital he developed bradycardia to the 40s and had a temporary pacing wire placed for prophylaxis prior to transfer here. he was started on iv nitroglycerin and was pain free upon arrival to ccu. his cardiac risk factors are the following: 1. tobacco. 2. hypertension. 3. no diabetes. 4. no family history. 5. no hypercholesterolemia. he was taken to the cardiac catheterization lab where he was found to have a right dominant system with total occlusion of his proximal lad with collateralization from his rca, moderate left circumflex disease and 80% proximal rca which collateralizing the lad. the proximal lad was angioplasty and descended successfully. past medical history: 1. hypertension. 2. coronary artery disease status post inferior myocardial infarction in . this was thrombolysed. medications on transfer: 1. aspirin 325 milligrams po q day. 2. plavix 75 milligrams po q day. 3. heparin drip. 4. iv nitroglycerin. allergies: no known drug allergies. social history: he smokes one and a half packs per day for 50 years. he denies any alcohol use. physical examination: temperature 92.2 f, pulse 74, blood pressure 114/59, respiratory 16, saturation 94% on room air. in general he is an elderly gentleman, comfortable, lying flat in no apparent distress. heent - pupils are equal, round and reactive to light. the sclerae are anicteric. oropharynx is clear. neck - no jvp. respiratory - clear to auscultation bilaterally. he has faint rales in the bases. cardiovascular - regular rate and rhythm, no murmurs, rubs, or gallops. abdomen exam is benign. extremities - no cyanosis, clubbing or edema. he has 2+ distal pulses. laboratory data: white count 7.5, hematocrit 40.9, platelet count 171,000, sodium 143, potassium 4.7, chloride 109, bicarb 26, bun 22, creatinine 1.1, glucose 134, pt 15, ptt 31. ck 1191 with an mb of 175, troponin 1.49. ekg reveals normal sinus rhythm with a rate of 88. he had left axis deviation with normal intervals. he had 1 to elevations in v1 to v3. chest x-ray revealed no evidence of infiltrate or chf. hospital course: mr. had no post catheterization complications except for one six beat run of nonsustained ventricular tachycardia. he had his temporary pacing wire removed. post catheterization without any consequence. the next day he returned to the cardiac catheterization lab where his proximal rca was stented. the lv gram determined that his ejection fraction was 43% with apical akinesis with moderate anterolateral, inferior posterior hypokinesis. he had no mitral regurgitation. he had no further runs of nonsustained ventricular tachycardia. examination of his left groin revealed no evidence of hematoma or femoral bruits. his distal pulses were 2+. his creatinine and hematocrit remained stable throughout two cardiac catheterizations. his ck fell steadily after his first catheterization and the patient remained chest pain free throughout his hospital stay. discharge condition: stable. discharge status: to home. medications: 1. toprol xl 25 milligrams po q day. 2. lisinopril 10 milligrams po q day. 3. plavix 25 milligrams po q day times 30 days. 4. lipitor 20 milligrams po q day. 5. enteric coated aspirin 325 milligrams po q day. 6. sublingual nitroglycerin 0.4 milligrams q five minutes times three prn chest pain. follow up: follow up with your primary care physician in on week. she should arrange for you to follow up with a cardiologist as soon as possible. instructions: return to the emergency room if you develop worsening chest pain, shortness of breath or develop worsening back pain, flank pain or leg pain. discharge diagnosis: 1. coronary artery disease. 2. hypertension. 3. hyperlipidemia. 4. acute myocardial infarction , m.d. dictated by: medquist36 d: 11:51 t: 11:58 job#: procedure: insertion of non-drug-eluting coronary artery stent(s) insertion of non-drug-eluting coronary artery stent(s) coronary arteriography using two catheters angiocardiography of left heart structures injection or infusion of platelet inhibitor left heart cardiac catheterization left heart cardiac catheterization diagnoses: coronary atherosclerosis of native coronary artery unspecified essential hypertension old myocardial infarction
