[The relation between lipoprotein fractions, sex and IHD in patients with primary hyperlipoproteinemia]
Insights
Primary hyperlipoproteinaemia (HLP) patients with ischaemic heart disease showed varied sex ratios by HLP type. Hypertriglyceridaemia altered this ratio, indicating complex cardiovascular risk factors.
Area of Science:
- Cardiology
- Metabolic Disorders
- Epidemiology
Context:
- Primary hyperlipoproteinaemia (HLP) is a group of genetic disorders affecting lipid metabolism.
- Assessing cardiovascular risk in HLP patients is crucial for timely intervention.
- Electrocardiogram (ECG) findings are key indicators of cardiac health.
Purpose:
- To analyze the relationship between known risk factors in primary hyperlipoproteinaemia (HLP) and ECG findings.
- To investigate the prevalence of ischaemic heart disease (IHD) in HLP patients.
- To determine the influence of different HLP types and lipid levels on IHD sex distribution.
Summary:
- A study of 228 primary hyperlipoproteinaemia patients revealed ischaemic heart disease (IHD) in 34%.
- HLP types IIa and IIb showed higher IHD rates in males, while HLP types III-V showed higher rates in females.
- Hypertriglyceridaemia, irrespective of HLP type, increasingly reversed the IHD sex ratio. Total cholesterol was a poor indicator of coronary risk.
Impact:
- Highlights the complex interplay of HLP type, hypertriglyceridaemia, and sex in cardiovascular risk stratification.
- Suggests that HDL-cholesterol's predictive value for coronary risk is relative and must be considered alongside triglyceride levels and sex.
- Underscores the need for personalized risk assessment in hyperlipoproteinaemia management beyond single lipid markers.
Abstract:
The evidence of known risk factors in 228 patients with primary hyperlipoproteinaemia was analysed in relation to the ECG-findings. In 34% of the patients symptoms of the ischaemic heart disease were present. In these cases the ischaemic heart disease prevailing rates for the HLP-types IIa and IIb were higher for the male sex, in the HLP-types III-V, on the other hand, higher for the female sex. With the appearance of the hypertriglyceridaemia, independent on the HLP-type, an increasing reversion of the sex ratio became evident. The total cholesterol level scarcely allowed evidence on the coronary risk in HLP-patients. The importance of the HDL-cholesterol as indicator of risk must be regarded in connection with the actual triglyceride values as well as with sex. Thus the general validity of the HDL-cholesterol was relative.
