Overview
Common causes of acute chest pain in the months after CABG include musculoskeletal pain from sternotomy: the most common cause, myocardial ischemia from acute graft stenosis or occlusion, pericarditis, pulmonary embolism, sternal wound infection , nonunion. Post-sternotomy pain syndrome is defined as discomfort after thoracic surgery, persisting for at least 2 months, and without apparent cause. The incidence of post-sternotomy pain syndrome is varied 7%-66% with a higher prevalence in women compared with men within the first 3 months of thoracic surgery but, after 3 months, postoperative sex difference in prevalence was not seen. Causes of Graft failure within the first year post-CABG using saphenous venous grafts are technical issues, intimal hyperplasia, thrombosis. Internal mammary artery graft failure within the first-year post-CABG is most commonly attributable to issues with the anastomotic site of the graft. Causes of acute chest pain several years after CABG include graft stenosis, occlusion or progression of disease in a non-bypassed vessel. One year after CABG, about 10%-20% of saphenous vein grafts fail. By 10 years, about half of saphenous vein grafts are patent. The internal mammary artery has patency rates of 90% to 95% 10 to 15 years after CABG. The use of radial artery grafts for CABG has a higher patency rate at 5 years of follow-up, compared with the use of saphenous vein grafts.
