Complications of CABG and hospital expenses Int J Cardiovasc Sci. 2019;32(1)28-34 Original Article This is an open-access article distributed under the terms of the Creative Commons Attribution License Another limitation of this study is related with the non- inclusion of patients who were readmitted precociously due to late surgical complications, since the discharge from hospital can happen before the occurrence of any clinical manifestation. Conclusions We conclude that the occurrence of complications during CABG hospitalization significantly increases the expenditures with the procedure, but the magnitude of this increase will depend on the type of complication developed, with the highest costs being related to cardiovascular complications, infectious complications and bleeding.
