What you need to know
Full lipid profile (total cholesterol, low density lipoprotein, high density lipoprotein, and triglyceride) is necessary for the diagnosis of hypercholesterolaemia
Ask about a family history of premature ischaemic heart disease and rule out secondary causes, such as type 2 diabetes mellitus or alcohol
Statins are first line management based on global cardiovascular disease risk assessment
A 40 year old man visits his general practitioner for annual antipsychotic monitoring. He is taking risperidone and sertraline for a previous diagnosis of psychotic depression. Recent blood tests showed a total cholesterol of 6.0, low density lipoprotein (calculated) (LDLc) 3.8, high density lipoprotein (HDL) 0.8, non-HDL 5.2, and triglyceride of 3.0 mmol/L; other blood tests were within the reference range.
Patients may require consideration of dyslipidaemia and cardiovascular risk for a number of reasons, including pre-existing physical health conditions such as chronic kidney disease; medications such as antipsychotics; family history such as hypercholesterolaemia or ischaemic heart disease; or due to age thresholds, such as cardiovascular disease (CVD) screening in over-40s.
This article provides a framework for diagnosing and managing dyslipidaemia, with the aim of reducing patients’ CVD risk.
What you should cover
Whether the person has a family history of either premature ischaemic heart disease or hypercholesterolaemia. Without this information, patients might undergo inappropriate risk score assessments which are not indicated for familial causes and might result in delayed diagnosis or undertreatment (fig 1).
The person’s diet (is it high in fat and/or sugar?)
Whether they smoke (or have recently stopped)
Their levels of physical activity
Alcohol consumption (does the person regularly consume more than 3 units/day (men) or 2 units/day (women)?).
