Summary
Selective coronary angiography in 559 patients revealed significant coronary artery disease in over 80% of cases, with the anterior descending artery most commonly affected. This diagnostic procedure showed a low mortality rate of 0.17%.
Area of Science:
- Cardiology
- Diagnostic Imaging
Background:
- Coronary heart disease (CHD) is a significant health concern.
- Accurate diagnosis of coronary artery stenosis is crucial for patient management.
Purpose of the Study:
- To evaluate the efficacy and safety of selective coronary angiography.
- To assess the prevalence and characteristics of coronary artery disease in a patient cohort.
Main Methods:
- Performed 600 selective coronary angiographies using Judkins preformed transfemoral catheters in 559 patients.
- Assessed stenosis severity, location, and number of diseased vessels.
- Measured ejection fraction to evaluate ventricular function.
Main Results:
- One fatality (0.17% mortality) and 15 cardiac complications (2.5%) were observed.
- Over 80% of patients with suspected CHD showed stenosis of at least 50% lumen diameter.
- The anterior descending artery was the most frequent site of stenosis; multi-vessel disease was common, especially in men.
- Impaired ventricular function was noted in one-third of cases.
Conclusions:
- Selective coronary angiography is a safe and effective diagnostic tool for coronary artery disease.
- The study highlights the high prevalence of significant coronary artery stenosis and multi-vessel disease.
- Findings underscore the importance of assessing ventricular function in patients with coronary artery disease.
