[Percutaneous selective coronarography. Apropos of 600 cases]
Insights
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.
Abstract:
600 selective coronary angiographies were performed in 559 patients, using Judkins preformed transfemoral catheters. One fatality was deplored (mortality: 0,17 p. 100). 15 cardiac complications were observed 2,5 p. 100), 10 of which were severe but rapidly corrected arrhythmias. Among these 559 patients 495 were clinically cases suffering from probable or certain coronary heart disease. 88 p. 100 of this group were men. Selective coronary angiography revealed stenosis with decrease of at least 50 p. 100 of the lumen in over 80 p. 100 of the cases. The anterior descending was the most frequent site of stenosis. In the majority of cases, and especially in men, two or several vessels were diseased. There is some relationship between the development of collateral circulation and the extension of coronary disease. In one third of the cases, ventricular function, assessed by measurement of the ejection fraction was impaired.
