Mortality related to coronary angiography
1Department of Cardiology, University Hospital, Linköping, Sweden.
Insights
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.
Abstract:
Coronary angiography is in general regarded as a safe investigation with a low risk of serious complications. Unfortunately, a risk of serious complications exists, especially in patients with left main coronary artery disease or 3-vessel disease. The mortality rate ranges in different studies between 0.10% to 0.25%. The present series, reflecting nine years experience, shows an overall mortality of 0.16%. This figure is influenced by the relatively high mortality rate in the first year of the study. The recent mortality rate of 0.07% has not changed in the last 3 years and almost all deaths occurred in the patients known to be at higher risk.
