Data from 3,105 older adults (65+) who had either heart surgery or cardiac catheterization has found that those who had heart surgery didn’t experience much greater cognitive decline compared with those who had the much less invasive, catheter-based procedure.
Two years after the surgery, surgery participants showed a greater amount of decline equal to only 4.6 months of cognitive aging compared with those undergoing catheterization.
