[The LDL-HDL ratio in patients with coronary arteriosclerosis (author's transl)]
Insights
The LDL-HDL ratio strongly correlates with coronary arteriosclerosis severity, unlike total cholesterol. This ratio offers better prediction of coronary risk, even with normal cholesterol levels.
Area of Science:
- Cardiovascular Medicine
- Lipid Metabolism
- Diagnostic Biomarkers
Context:
- Coronary arteriosclerosis assessment relies on angiographic scoring.
- Total serum cholesterol has shown limited correlation with disease extent.
- Lipoprotein profiles are crucial in understanding cardiovascular risk.
Purpose:
- To evaluate the correlation between total serum cholesterol, LDL-HDL ratio, and coronary arteriosclerosis severity.
- To determine the predictive power of the LDL-HDL ratio versus total cholesterol for coronary risk.
Summary:
- A study of 171 patients revealed a weak correlation between total cholesterol and coronary arteriosclerosis extent.
- A strong correlation was found between the low-density lipoprotein to high-density lipoprotein (LDL-HDL) ratio and the severity of coronary arteriosclerosis.
- The LDL-HDL ratio demonstrated higher predictive power for coronary risk compared to total cholesterol, particularly when cholesterol levels were within the normal range.
Impact:
- Highlights the LDL-HDL ratio as a superior biomarker for assessing coronary arteriosclerosis.
- Suggests a shift in diagnostic focus towards lipoprotein patterns for cardiovascular risk stratification.
- Informs clinical practice regarding more accurate prediction of coronary heart disease risk.
Abstract:
In 171 patients with coronary arteriosclerosis the severity of the angiographic findings was assessed by the score of Friesinger. The total serum cholesterol concentration showed an only weak positive correlation with the extent of coronary arteriosclerosis. In contrast, a strict correlation could be documented with the LDL-HDL ratio. The LDL-HDL ratio was 1.49 in the control group with angiographically free coronary arteries, 1.95 in patients with an angiographic score of 1-5, 2.39 at a score of 6-10, and 2.75 at a score of 11-15. The corresponding total serum cholesterol values (control group: 219 mg/100 ml) were 229 mg/100 ml, 242 mg/100 ml and 258 mg/100 ml. Especially at still normal serum cholesterol concentrations an already pathological shift in the lipoprotein pattern in correlation with the extent of coronary arteriosclerosis was indicated by the LDL-HDL ratio. Thus a greater predictive power for coronary risk is attributed to the LDL-HDL ratio rather than to the total serum cholesterol concentration.
