[Vascular complications in primary hyperlipoproteinemias (HLP) with special reference to changes in the eye fundus]
Insights
Hyperlipoproteinaemia types IIa/IIb and IV/V show distinct prevalence peaks. Associated risks like hypertension, diabetes, and vascular conditions are more severe in types IV/V and III, highlighting the need for targeted interventions.
Area of Science:
- Cardiology and Metabolic Disorders
- Lipid Metabolism and Vascular Health
Context:
- Hyperlipoproteinaemia classification and prevalence.
- Association of metabolic factors (weight, glucose tolerance) with hyperlipoproteinaemia types.
- Prevalence of hypertension as a cardiovascular risk factor.
Purpose:
- To analyze the distribution of hyperlipoproteinaemia types.
- To investigate the relationship between hyperlipoproteinaemia types and metabolic/vascular risk factors.
- To assess the impact of co-existing hypertension and diabetes on vascular risk.
Summary:
- Two main hyperlipoproteinaemia prevalence peaks identified: types IIa/IIb (41%) and types IV/V (55%).
- Types III-V exhibit significantly higher weight indices and impaired glucose tolerance compared to types IIa/IIb.
- Hypertension present in 34%; myocardial infarctions highest in types IIb/III, peripheral artery disease (PAD) in type III.
- Comorbidities like hypertension and diabetes exacerbate vascular risk in hyperlipoproteinaemia.
- Fundus changes suggestive of hypertensive retinopathy indicate potential hyperlipoproteinaemia even in normotensive individuals.
Impact:
- Identifies specific hyperlipoproteinaemia types with elevated metabolic and vascular risks.
- Underscores the compounded vascular risk when hyperlipoproteinaemia coexists with hypertension and diabetes.
- Suggests funduscopic examination as a potential screening tool for hyperlipoproteinaemia in hypertensive patients.
Abstract:
The distribution of the types of hyperlipoproteinaemias revealed 2 peaks of frequency, i. e. in the types IIa and IIb corresponding 41% and in the types IV and V corresponding 55%. Weight indices and disturbed glucose tolerance are in the types III-V significantly higher than in the types IIa and IIb. The risk factor hypertension was registered in 34% in the investigation material. The highest prevalence rates for myocardial infarctions were in the patients of the types IIb and III, for PAD in the type III. The addition of hypertension and diabetes mellitus to hyperlipoproteinaemia reveals an exacerbation of the vascular risk. Changes of the fundus oculi, which correspond to the picture of a fundus hypertonicus cause to think of the presence of a hyperlipoproteinaemia in all patients with normotension.
