Multiple coronary bypass grafting: current mortality and morbidity
Southern Medical Journal
|September 1, 1979
Summary
Coronary artery bypass grafting is safe and effective for patients with severe coronary artery disease, including those with stable angina. This study found a low operative mortality and morbidity, supporting its use in select patient groups.
Area of Science:
- Cardiology
- Cardiac Surgery
Background:
- Coronary artery bypass surgery (CABS) is increasingly common but its efficacy is debated in certain patient populations.
- Critical reports question the benefits of CABS for specific patient groups.
Purpose of the Study:
- To review the safety and efficacy of multiple coronary bypass grafting for triple vessel disease.
- To evaluate the outcomes of CABS in patients with high-grade double and triple vessel disease and stable angina.
Main Methods:
- Retrospective review of 276 patients undergoing multiple coronary bypass grafting between March 1976 and October 1978.
- Inclusion of combined procedures such as valve replacement and ventricular aneurysmectomy.
- Analysis of operative mortality, perioperative infarction, and other nonfatal complications.
Main Results:
- Low operative mortality of 0.7% (2 deaths within 30 days) in 276 patients.
- Perioperative infarction occurred in 4% of patients (11 patients).
- Other nonfatal operative complications were reviewed and found to be manageable.
Conclusions:
- Coronary artery bypass surgery demonstrates overall safety and low morbidity in this patient cohort.
- The findings support the recommendation of CABS for controversial subsets, including patients with high-grade double and triple vessel disease and stable angina.
