Will my heart's pumping function get worse one year after coronary artery bypass grafting?
Coronary artery bypass grafting (CABG) is a major surgery to improve blood flow to the heart. While the main goal is to restore blood supply, the mechanical behavior of the heart muscle can change over time. Research shows that while the overall pumping strength remains stable, the heart's ability to relax and fill with blood typically declines one year after the procedure.
What the research says
Other factors like pain management and recovery quality also affect the post-surgery experience but do not directly reverse the mechanical changes in the heart muscle 13. For example, using nerve stimulation or smartphone-based nursing programs can reduce pain and improve recovery quality 13, but these interventions do not stop the natural stiffening of the heart muscle observed in the one-year follow-up data 2.
What to ask your doctor
- How will the change in my heart's ability to relax affect my daily activities one year after surgery?
- What symptoms should I watch for if my heart muscle becomes stiffer over time?
- Are there specific exercises or medications that can help improve my heart's filling function?
- How often should I have an echocardiogram to check my heart's mechanical properties?
