Summary
Coronary angiography is generally safe, but risks increase for patients with complex coronary artery disease. Recent mortality rates are low, primarily affecting high-risk individuals.
Area of Science:
- Cardiology
- Interventional Cardiology
- Medical Imaging
Background:
- Coronary angiography is a common diagnostic procedure.
- While generally safe, serious complications can occur.
- Higher risk is noted in patients with left main or 3-vessel coronary artery disease.
Purpose of the Study:
- To evaluate the safety and mortality rates of coronary angiography.
- To analyze trends in complication risks over time.
- To identify patient groups with elevated risks.
Main Methods:
- Retrospective analysis of nine years of coronary angiography data.
- Calculation of overall and recent mortality rates.
- Stratification of risk based on coronary artery disease complexity.
Main Results:
- Overall mortality in the study cohort was 0.16%.
- Recent mortality rates have decreased to 0.07% and remained stable.
- Deaths predominantly occurred in patients with known high-risk factors.
Conclusions:
- Coronary angiography remains a relatively safe procedure.
- Risk stratification is crucial for patient management.
- Ongoing monitoring shows a favorable safety profile in recent years.
