Insights
Coronary heart disease patients often show ventricular dysfunction, especially younger individuals. However, older patients (over 50) with vascular lesions may not exhibit these cardiac abnormalities.
Area of Science:
- Cardiology
- Diagnostic Imaging
Background:
- Coronary heart disease (CHD) involves narrowed or blocked coronary arteries.
- Ventricular dysfunction can be a consequence of significant coronary artery disease.
Purpose of the Study:
- To investigate the relationship between coronary artery disease severity and ventricular dysfunction.
- To assess age-related differences in the presentation of ventricular dysfunction in CHD patients.
Main Methods:
- Ventriculography was performed on 154 patients with confirmed coronary heart disease (high-grade stenosis or total occlusion).
Main Results:
- Functional disorders or morphologic changes were observed in 81% of patients.
- Older patients (>50 years) with vascular lesions frequently lacked ventricular dysfunction.
- All patients under 40 years old showed abnormal ventriculograms, irrespective of lesion extent.
Conclusions:
- Ventricular dysfunction is common in coronary heart disease patients.
- Age significantly influences the manifestation of ventricular dysfunction in the context of coronary artery disease.
Abstract:
Ventriculography was performed in 154 patients with angiographic evidence of coronary heart disease (high-grade stenosis or total occlusion). Functional disorders or morphologic changes were demonstrated in 81% of cases. However, vascular lesions were often found without evidence of ventricular dysfunction in patients over 50 years of age. In contrast, all patients younger than 40 years of age demonstrated abnormal ventriculograms, even when vascular pathology was limited to a single vessels.
