Insights
Low HDL cholesterol is a major cardiovascular risk factor, often linked to other lipid issues. Treatment decisions for low HDL cholesterol depend on a patient
Area of Science:
- Cardiovascular Medicine
- Lipidology
- Metabolic Syndrome
Context:
- Low high-density lipoprotein (HDL) cholesterol is a significant cardiovascular risk factor.
- Prevalent lipid abnormality in patients with coronary heart disease.
- Often associated with hypertriglyceridaemia and insulin resistance syndrome.
Purpose:
- To highlight the significance of low HDL cholesterol as a cardiovascular risk factor.
- To discuss the associations of low HDL cholesterol with other metabolic conditions.
- To emphasize the importance of individualized cardiovascular risk assessment for treatment decisions.
Summary:
- Decreased plasma HDL cholesterol is a major cardiovascular risk factor, prevalent in coronary heart disease patients.
- This condition frequently co-occurs with hypertriglyceridaemia, insulin resistance, or elevated LDL cholesterol.
- Treatment for low HDL cholesterol necessitates careful evaluation of overall individual cardiovascular risk and underlying causes.
Impact:
- Informs clinical practice regarding the assessment and management of low HDL cholesterol.
- Underscores the need to investigate contributing factors like lifestyle and medications.
- Contributes to a better understanding of lipid abnormalities in cardiovascular disease.
Abstract:
A decrease in plasma HDL cholesterol concentration is considered as a major cardiovascular risk factor and is a prevalent lipid abnormality among patients with coronary heart disease. This condition is most often observed in the presence of hypertriglyceridaemia, generally linked to the insulin resistance syndrome, but may also be associated to elevated LDL cholesterol level or even be present alone (hypoalphalipoproteinaemia). The decision to treat a patient with low HDL level depends on the individual overall cardiovascular risk which should be evaluated as carefully as possible. The investigation should look for causes which may favour this metabolic condition, such as bad life habits or possible pharmacological interferences.
