In this episode, Dr Kevin Fernando considers the case of Juliana, a 43-year-old journalist who requests a cholesterol check because her father experienced a heart attack in his early 50s. She has no past medical history of note. Her lipid profile returns as follows: total cholesterol (TC), 7.5 mmol/L; HDL-cholesterol, 1.4 mmol/L; triglycerides, 2.2 mmol/L; LDL-cholesterol, 2.9 mmol/L. What should we do next, and what do current guidelines recommend regarding the detection and management of familial hypercholesterolaemia (FH)?
