Coronary artery bypass surgery aims to prevent death from coronary artery disease and improve quality of life by relieving angina, the associated feeling of chest pain. [1] The decision to perform surgery is informed by studies of CABG's efficacy in different patient subgroups, based on the lesions' anatomy or how well the heart is functioning.
A related study by Selnes et al. [7] concluded patients with coronary artery bypass grafting did not differ from a comparable nonsurgical control group with coronary artery disease 1 or 3 years after baseline examination. This finding suggests that late cognitive decline after coronary artery bypass grafting previously reported by Newman et al ...
Emergency bypass surgery for the treatment of an acute myocardial infarction (MI) is less common than PCI or thrombolysis. From 1995 to 2004, the percentage of people with cardiogenic shock treated with primary PCI rose from 27.4% to 54.4%, while the increase in coronary artery bypass graft surgery (CABG) was only from 2.1% to 3.2%.

Minimally invasive direct coronary artery bypass (MIDCAB) is a surgical treatment for coronary heart disease that is a less invasive method of coronary artery bypass surgery (CABG). [1] MIDCAB gains surgical access to the heart with a smaller incision than other types of CABG.
Medications such as nitrates and beta-blockers may be useful for reducing the symptoms of coronary ischemia. [6] In refractory cases, invasive procedures such as percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) may be performed to relieve coronary ischemia. [14]
Off-pump coronary artery bypass (OPCAB), or beating-heart surgery, is a form of coronary artery bypass graft (CABG) surgery performed without cardiopulmonary bypass (heart-lung machine) as a treatment for coronary heart disease. It was primarily developed in the early 1990s by Dr. Amano Atsushi.
Treatment involves the same measures as prevention. [10] [22] Additional medications such as antiplatelets (including aspirin), beta blockers, or nitroglycerin may be recommended. [10] Procedures such as percutaneous coronary intervention (PCI) or coronary artery bypass surgery (CABG) may be used in severe disease.
A heart attack during or shortly after the procedure occurs in 0.3% of cases; this may require emergency coronary artery bypass surgery. [13] Heart muscle injury characterized by elevated levels of CK-MB, troponin I, and troponin T may occur in up to 30% of all PCI procedures. Elevated enzymes have been associated with later clinical outcomes ...
