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 50 year old male with a past medical history of psoriasis who presented to an outside hospital complaining of chest pain of one day duration. he was watching a baseball game the night prior to admission and initially felt a left arm numbness with several twinges of chest discomfort. there was no nausea and vomiting that was associated. when the patient presented to the outside hospital the patient was ruled out for an acute myocardial infarction by enzyme and received medical treatment and was chest pain free. he underwent an exercise tolerance test which showed a 1 mm st segment depression in lead 2, 3 and avf, and st segment depression in v1 through v6 with t wave inversion during the recovery period. given this positive exercise tolerance test, the patient was transferred to the for cardiac catheterization. the medical history is significant only for psoriasis. the patient denies any allergies to medications and does not take any medications at home. the patient's social history is not significant and he denies any tobacco. the patient occasionally drinks alcohol. the family history is not significant for any coronary artery disease. physical examination: on physical examination on admission, the patient was afebrile at 98.0, heartrate 66, blood pressure 134/61, respiratory rate 20, sating 94% on room air. the patient was lying comfortably in bed, alert and oriented times three, not in apparent distress. head, eyes, ears, nose and throat examination showed the pupils equally round and reactive to light and accommodation with extraocular movements intact. the neck was supple, no jugulovenous distension. the chest examination was clear to auscultation bilaterally. the cardiac examination was regular rate and rhythm with s1 and s2, no murmurs were appreciated. the abdominal examination was with good bowel sounds, soft, nontender, nondistended. extremities were warm without any evidence of edema, cyanosis or clubbing. neurologically the patient's cranial nerves ii through xii were grossly intact and the patient did not have any gross motor or sensory deficits. laboratory data: laboratory data on admission revealed white count 8.1, hematocrit 40.4, platelet of 314. pt/ptt were 12.6 and 24.2 respectively with an inr of 1.1. chemistry, sodium 134, potassium 3.7, chloride 103, carbon dioxide 22, bun 10, creatinine 0.7 and glucose 111. .................. was 30. alkaline phosphatase was 51, total bilirubin 0.8, amylase 45. chest x-ray at the outside hospital showed no infiltrates or consolidations in the lung fields and there were no pulmonary effusions noted. the patient underwent a cardiac catheterization on and was found to have a hazy 70% proximal stenosis of the left anterior descending and a 90% stenosis of the proximal left circumflex involving the origin of the obtuse marginal 1 and an 80% distal stenosis of the left circumflex involving the origin of obtuse marginal 3. there was no significant disease reported in the nondominant right coronary artery. the left ventriculogram showed no mitral regurgitation and calculated ejection fraction was 45%. there was mild diffuse hypokinesis that was noted. hospital course: given the extent of the disease process of the left circumflex artery (the proximal segment with obtuse marginal 1 and the distal segment with obtuse marginal 3), the patient essentially had a three vessel disease and cardiac surgery consult was called. , m.d. dictated by: medquist36 procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery coronary arteriography using two catheters (aorto)coronary bypass of two coronary arteries angiocardiography of left heart structures left heart cardiac catheterization diagnoses: coronary atherosclerosis of native coronary artery cardiac complications, not elsewhere classified atrioventricular block, complete surgical operation with anastomosis, bypass, or graft, with natural or artificial tissues used as implant causing abnormal patient reaction, or later complication, without mention of misadventure at time of operation ventricular fibrillation accidents occurring in residential institution acute myocardial infarction of inferoposterior wall, initial episode of care other psoriasis 

Answer: The patient is high likely exposed to
