Summary
Coronary artery bypass grafting (CABG) for ischemic cardiomyopathy (ICM) with low ejection fraction (EF) shows acceptable operative mortality and 5-year survival rates. These outcomes are comparable to heart transplantation for similar patients.
Area of Science:
- Cardiology
- Cardiac Surgery
- Medical Research
Background:
- Coronary artery bypass grafting (CABG) is a common procedure for coronary artery disease.
- Ischemic cardiomyopathy (ICM) with severely reduced ejection fraction (EF < 20%) presents a significant surgical challenge.
- Outcomes for CABG in patients with ICM and low EF require careful evaluation.
Observation:
- The study reviewed 2,235 coronary surgical patients from June 1970 to August 1995.
- A cohort of 29 patients (1.8%) with ICM underwent elective, isolated CABG with EF < 20%.
- Hospital mortality was 6.9% (2 cases), with 2 late mortality cases observed.
Findings:
- Graft patency rate was high at 96.6%.
- Actuarial survival rates were 93% at 1 year, 93% at 3 years, and 87% at 5 years.
- Operative mortality and 5-year survival for CABG in ICM patients were deemed acceptable.
Implications:
- CABG for ICM with low EF offers acceptable short-term and long-term outcomes.
- These results suggest CABG is a viable option comparable to heart transplantation for select ICM patients.
- Further research may refine patient selection and surgical techniques for ICM.
