[Is coronarography justified in unstable angina? Experience of 130 cases]
Insights
Selective cine-coronary-arteriography and ventriculography precisely diagnose unstable angina. Early detection of coronary arterial lesions aids in determining prognosis and treatment strategies before myocardial infarction occurs.
Area of Science:
- Cardiology
- Diagnostic Imaging
Background:
- Unstable angina requires accurate assessment of coronary arterial status.
- Identifying obstructive atherosclerotic lesions is crucial for patient management.
Purpose of the Study:
- To demonstrate the features of selective cine-coronary-arteriography in patients with unstable angina.
- To evaluate the diagnostic utility of cine-coronary-arteriography and ventriculography for left ventricular function.
Main Methods:
- Retrospective analysis of 130 selective cine-coronary-arteriography investigations.
- Inclusion of ventriculography and measurement of ventricular pressures.
- Assessment of risk in patients with unstable versus chronic angina.
Main Results:
- Cine-coronary-arteriography effectively visualizes the extent and location of obstructive atherosclerotic lesions.
- Ventriculography and pressure measurements provide insights into left ventricular function and kinetics.
- The diagnostic procedures were found to be safe in unstable angina patients.
Conclusions:
- Selective cine-coronary-arteriography and ventriculography enable precise diagnosis in unstable angina.
- Early identification of significant coronary lesions allows for informed prognosis and treatment planning.
- These methods facilitate timely intervention to prevent myocardial infarction.
Abstract:
The many important features of selective cine-coronary-arteriography to show the coronary arterial tree are demonstrated in the study of 130 such investigations carried out in patients with unstable angina. Cine-coronary-arteriography shows up the extent and location of obstructive atherosclerotic lesions. Ventriculography, together with measurement of ventricular pressures, gives information about the function and kinetic status of the left ventricle. These two investigations which do not, in our opinion, carry a greater risk in these cases than in cases with chronic angina, allow a precise diagnosis to be made. The early discovery of major lesions before infarction has occurred allow conclusions to be drawn about the prognosis and the appropriate treatment.
