This retrospective study compares long-term survival between patients undergoing off-pump coronary artery bypass (OPCAB) and those receiving on-pump coronary artery bypass (ONCAB) procedures. By analyzing a large, well-characterized dataset, the study aims to assess differences in survival rates between the two techniques.
The goal is to provide clinically meaningful insight into which surgical strategy offers improved outcomes over time, with potential implications for surgical planning and patient selection.
