Hypothesis
Does waiting longer than recommended for coronary artery bypass grafting (CABG) increase in-hospital mortality?
Conclusion
Delaying CABG surgery significantly increases the risk of in-hospital death.
Supporting Evidence
- Patients who underwent CABG within the recommended time had a lower in-hospital death rate of 1.0% compared to 1.5% for those who were delayed.
- For every additional month of delay before surgery, the odds of in-hospital death increased by 5%.
- The study adjusted for various factors including age, sex, and comorbidities to ensure accurate results.
Takeaway
If you have heart surgery, it's better to have it sooner rather than later because waiting too long can make you more likely to die in the hospital.
Methodology
The study analyzed data from a population-based registry of patients who underwent isolated CABG in British Columbia, comparing outcomes based on the timing of surgery.
Potential Biases
Potential misclassification of urgency for treatment and changes in urgency at the time of surgery could bias results.
Limitations
The study did not include patients who underwent surgery without being on a wait list and lacked external validation of registry data.
Participant Demographics
The cohort included adult patients with established coronary artery disease, predominantly male (83%) and aged 60-79 years.
