[Correlation between serum lipid level and coronary bed lesions in patients with ischemic heart disease]
Insights
Total cholesterol and low-density lipoprotein cholesterol levels directly correlate with coronary atherosclerosis severity in heart disease patients. High-density lipoprotein cholesterol changes are unreliable indicators for assessing coronary artery disease progression.
Area of Science:
- Cardiovascular Medicine
- Clinical Biochemistry
- Medical Diagnostics
Context:
- Coronary heart disease (CHD) is a leading cause of mortality worldwide.
- Accurate assessment of atherosclerotic damage is crucial for effective CHD management.
- Blood lipid profiles are commonly analyzed as potential indicators of cardiovascular risk.
Purpose:
- To investigate the correlation between specific blood lipid levels and the extent of atherosclerotic damage in the coronary arteries of patients with established coronary heart disease.
- To determine the diagnostic value of various lipid parameters in assessing the severity of coronary atherosclerosis.
Summary:
- This study analyzed blood lipid levels in 124 patients with coronary heart disease (CHD).
- A significant positive correlation was observed between elevated total cholesterol and low-density lipoprotein cholesterol (LDL-C) levels and the degree of coronary atherosclerotic lesions.
- Conversely, high-density lipoprotein cholesterol (HDL-C), very low-density lipoprotein cholesterol (VLDL-C), and the atherogenicity index showed no significant correlation with the severity of coronary atherosclerosis. A trend towards increased triglyceride levels was noted.
- The findings suggest that total cholesterol and LDL-C are reliable indicators for evaluating CHD severity.
Impact:
- Recommends focusing on total cholesterol and LDL-C measurements for assessing coronary atherosclerosis severity in clinical practice.
- Highlights the limited utility of HDL-C and other lipid parameters in quantifying the extent of coronary artery disease.
- Informs clinical guidelines for CHD risk stratification and patient management by identifying key lipid biomarkers.
Abstract:
The blood lipid levels were collated with the atherosclerotic damage to the coronary bed in 124 patients with coronary heart disease. An increase in the content of total cholesterol and low density lipoprotein cholesterol directly correlated with the degree of the total lesion of the coronary bed. The concentrations of high density cholesterol and very low density cholesterol and the atherogenicity index showed no correlation with the severity of atherosclerotic changes in the coronary arteries. The level of triglycerides in these patients displayed a tendency to increase. In evaluating the severity of coronary heart disease, it is recommended to determine the levels of total cholesterol and low density lipoprotein cholesterol. Changes in the concentration of high density lipoprotein cholesterol are unreliable for assessing the degree of coronary atherosclerosis.
