Insights
Urgent coronary angiography in patients with acute myocardial infarction reveals severe coronary artery disease, with 71.4% having vessels suitable for revascularization. Left ventricular contractility disorders were common in 81.6% of cases.
Area of Science:
- Cardiology
- Interventional Cardiology
- Cardiac Imaging
Background:
- Pre-infarction state and acute myocardial infarction (AMI) are critical cardiovascular conditions.
- Early diagnosis and intervention are crucial for improving patient outcomes.
Purpose of the Study:
- To analyze the results of urgent coronary angiography and ventriculography in patients with pre-infarction state and AMI.
- To assess the severity of coronary artery disease and left ventricular function in these patients.
Main Methods:
- Urgent coronary angiography and ventriculography were performed on 95 patients.
- Analysis of angiographic findings and left ventricular contractility.
Main Results:
- An average of 13 hours and 40 minutes elapsed between the onset of anginal attack and the end of coronarography.
- 13 patients (13.7%) had angiographically normal coronaries, with 2 of them experiencing myocardial infarction.
- Coronary artery disease was more severe in patients with pre-infarction state and AMI compared to stable angina pectoris.
- 71.4% of patients had coronary vessels suitable for myocardial revascularization.
- Left ventricular contractility disorders were observed in 81.6% of cases.
Conclusions:
- Patients with pre-infarction state and AMI exhibit more severe coronary artery disease than those with stable angina.
- A significant proportion of these patients have suitable coronary vessels for revascularization.
- Impaired left ventricular contractility is a frequent finding in this patient cohort.
Abstract:
The results of urgent coronarography and ventriculography in 95 patients with pre-infarction state and acute myocardial infarction are analyzed. It is established that from the beginning of the acute anginal attack till the end of coronarography 13 h 40 min (average) have elapsed. In 13 patients angiographically normal coronaries have been found, 2 of them had myocardial infarction. It is recorded that in patients with pre-infarction state and acute myocardial infarction the affection of the coronaries is more severe than in those with stable angina pectoris. Coronary vessels fit for revascularization of the myocardium were found in 71.4% of patients. Disorders of contractility of the left ventricle were seen in 81.6% of cases.
