In this video, Dr. Viveka Kumar, Senior Director - Cath Lab, Max Super Speciality Hospital, Saket, will discuss the role of CABG in acute MI, in this video. Bypass surgery has a high mortality whereas thrombolysis and primary PCI have shown to decrease the mortality. If the patient has a bad anatomy and the lesions are calcified then these are certain situations when the patients can undergo bypass surgery. He will explain that if the patient is taken for bypass surgery within 6 hours of MI, then the mortality is low. If the patient is taken for the surgery after 6 hours to 48 hours then the mortality is as high as 50%. Bypass surgery is only recommended when primary PCI is not feasible.
