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: allergies: patient recorded as having no known allergies to drugs attending: chief complaint: chest pain, shortness of breath major surgical or invasive procedure: three vessel coronary artery bypass grafting utilizing left internal mammary artery to left anterior descending, saphenous vein graft to obtuse marginal, saphenous vein graft to plv. history of present illness: this is a 70 year old male with known coronary disease. he sustained a myocardial infarction in and underwent stenting to his lad at that time. he continued to experience angina and exertional shortness of breath. an echocardiogram in was notable for an lvef of 30-35% with mild mr. subsequent cardiac catheterization found an occluded lad stent with 60% lesion in his circumflex and 70% diagonal stenosis. based on the above results, he was referred for cardiac surgical intervention. past medical history: coronary artery disease - as above, hypertension, hypercholesterolemia, chonic obstructive pulmonary disease, s/p left nephrectomy, right hip fracture, s/p prostatectomey, artificial urinary sphincter, sleep apnea, gastroesophageal refulx disease, s/p parathyroidectomy, s/p vasectomy, cataract surgery social history: retired machinist. no significant tobacco or etoh history. lives alone. family history: parents and sibling had cad -
