Hypothesis
Can right ventricular function predict short term outcomes after coronary artery bypass graft surgery?
Conclusion
Right ventricular function assessed by cardiac MRI can predict ICU and hospital length of stay, but not short or long term mortality after CABG.
Supporting Evidence
- 202 patients were included in the study.
- Median ICU length of stay was significantly different between normal and reduced RVF groups.
- RVF was independently associated with ICU length of stay after adjusting for STS score.
Takeaway
Doctors used a special heart scan to see if how well the right side of the heart works can help predict how long patients will stay in the hospital after heart surgery.
Methodology
Patients who had cardiac MRI before CABG were studied to see the relationship between right ventricular function and surgical outcomes.
Limitations
The study may not account for all factors influencing outcomes after CABG.
Participant Demographics
Patients who underwent CABG from January 2003 to February 2010.
