Coronary artery stenosis in patients with valvular heart disease
Insights
For patients with valvular heart disease (VHD), high cholesterol and lower limb arteriosclerosis are key indicators of coronary artery stenosis. Consider coronary angiography before surgery if these risk factors are present in patients over 40.
Area of Science:
- Cardiology
- Vascular Medicine
- Diagnostic Imaging
Background:
- Valvular heart disease (VHD) often coexists with coronary artery disease.
- Accurate diagnosis of coronary artery stenosis is crucial for surgical planning in VHD patients.
Purpose of the Study:
- To evaluate the diagnostic accuracy of clinical indicators for coronary artery stenosis in patients with VHD.
- To identify predictive factors for significant coronary narrowing in this population.
Main Methods:
- Selective coronary angiography was performed on 144 patients with VHD.
- Clinical indexes, including cholesterol levels and lower limb arteriosclerosis, were analyzed.
- Diagnostic accuracy of these indexes was assessed.
Main Results:
- Significant coronary artery stenosis was detected in 26% of patients.
- Increased cholesterol level and presence of arteriosclerosis in lower limbs were the most useful predictors.
- These indicators showed higher diagnostic accuracy for coronary narrowing.
Conclusions:
- Elevated cholesterol and lower limb arteriosclerosis are significant predictors of coronary artery stenosis in VHD patients.
- Coronary angiography is recommended prior to surgical treatment for VHD patients over 40 with both indicators.
Abstract:
144 patients with valvular heart disease (VHD) underwent selective coronary angiography. Significant coronary artery stenosis was found in 26% of the examined patients. Diagnostic accuracy of some clinical indexes was analysed in this group. Most useful in predicting the presence of significant coronary narrowing in patients with VHD were increased cholesterol level and the presence of arteriosclerosis in lower limbs. Patients over 40 years who have both these indicators should have coronary angiography performed prior to surgical treatment.
