Summary
Surgical treatment for stable angina pectoris involves careful risk assessment. Outcomes vary with ejection fraction, with lower fractions indicating higher mortality risks after coronary artery bypass grafting.
Area of Science:
- Cardiovascular Surgery
- Cardiac Anesthesia
- Interventional Cardiology
Background:
- Stable angina pectoris significantly impacts patient quality of life.
- Surgical intervention is a key treatment modality for managing stable angina.
- Accurate risk stratification is crucial for optimizing surgical outcomes.
Purpose of the Study:
- To outline the principles of surgical treatment for stable angina pectoris.
- To emphasize the importance of operative risk estimation.
- To present outcomes of coronary artery bypass grafting (CABG) in a patient cohort.
Main Methods:
- Review of surgical indications, contraindications, and techniques for stable angina.
- Analysis of operative risk factors, including left ventricular ejection fraction (LVEF).
- Retrospective review of 291 patients undergoing CABG between 1980-1982.
Main Results:
- Average of 2.7 bypass grafts per patient.
- Overall in-hospital mortality was 1.4%.
- Mortality rates correlated inversely with LVEF: 0% for LVEF ≥40%, 2.5% for LVEF 30-40%, and 13.3% for LVEF <30%.
- Peri- or postoperative ischemic events occurred in 2.4% of patients.
Conclusions:
- Surgical treatment for stable angina is effective, with outcomes influenced by patient risk factors.
- Left ventricular ejection fraction is a critical predictor of mortality following CABG.
- Careful patient selection and risk assessment are paramount for successful surgical management of stable angina.
