[Coronary surgery at the Heart Center in Oslo 1989-98]
Insights
Coronary artery bypass grafting outcomes remained stable despite an aging patient population and increased surgical risk. Advances in technology and surgical strategies ensure safety for all patients undergoing this procedure.
Area of Science:
- Cardiovascular Surgery
- Medical Technology Trends
- Patient Risk Stratification
Context:
- Coronary artery bypass grafting (CABG) is a critical cardiac procedure.
- Patient demographics and surgical approaches evolve over time.
- A decade of CABG data (1989-1998) provides a unique opportunity to analyze trends.
Purpose:
- To analyze trends in patient characteristics and surgical strategies for CABG.
- To evaluate the impact of these changes on surgical outcomes.
- To assess the safety and efficacy of CABG over a 10-year period.
Summary:
- Analysis of 5,658 CABG patients from 1989-1998 revealed an increase in median patient age and the proportion of female patients.
- The percentage of patients with a high operative risk profile significantly increased from 23.7% to 61.8%.
- Despite these changes, morbidity and hospital mortality rates remained consistently low (0.41% overall), attributed to advancements like heparin-coated extracorporeal equipment and blood cardioplegia.
Impact:
- Surgical outcomes for CABG remained favorable despite a sicker patient population.
- Continuous improvements in technical equipment and treatment strategies enhance patient safety.
- CABG is a safe and effective treatment option for both high-risk and low-risk individuals.
Background:
Coronary artery bypass grafting was performed in 5,658 consecutive patients during the period 1989-1998. Due to changes over time, both in patients' risk profile and surgical strategies, a review was undertaken to study trends and results after coronary artery bypass surgery.
Material And Methods:
Our database includes more than 160 variables per patient, covering preoperative risk factors, catheterization data, operative and postoperative results. These data form the basis for analysis over time.
Results:
Median age increased for both genders, from 58 years to 64 years for males and 62.5 years to 69 years for females. The female proportion increased from 12.8% to 19.8%. A high operative risk profile was registered in 23.7% in 1989 compared to 61.8% in 1998. Heparin-coated extracorporeal equipment and blood cardioplegia were gradually introduced in routine practice. Despite higher age and operative risk profile the morbidity and hospital mortality (0.41% overall) remained nearly unchanged.
Interpretation:
Due to continuous improvement of technical equipment and treatment strategies, coronary artery bypass surgery represents a safe option for both high and low risk patients.
