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: dyspnea on exertion major surgical or invasive procedure: s/p coronary artery bypass graft surgery (left internal mammary artery>left anterior descending, saphenous vein graft>diagonal, saphenous venin graft>obtuse marginal1, saphenous vein graft>obtuse marginal2, saphenous vein graft>right coronary artery) history of present illness: 69 year old male with six months of chest heaviness and dyspnea on exertion. referred for cardiac catherization that revealed coronary artery disease and was referred for surgical intervention. past medical history: coronary artery disease sleep apnea on cpap exposure in hiatal hernia social history: works in shipping packaging company
