Approach to dyslipidemia, Task 3 When will u consider prescribing statins…
Approach to dyslipidemia
When to consider screening:
All men and women aged 40 years or older (including postmenopausal women).
Consider earlier screening in ethnic groups at increased cardiovascular risk, such as South Asian or Indigenous individuals.
All patients with any of the following conditions regardless of age:
Clinical evidence of atherosclerosis
Abdominal aortic aneurysm
Diabetes mellitus
Arterial hypertension
Current cigarette smoking
Stigmata of dyslipidemia (like corneal arcus, xanthelasma, xanthoma)
Family history of premature cardiovascular disease or dyslipidemia
Chronic kidney disease (eGFR ≤60 mL/min/1.73 m² or albumin-to-creatinine ratio (ACR) ≥3 mg/mmol for at least 3 months)
Obesity (BMI ≥30 kg/m²)
Inflammatory diseases (such as rheumatoid arthritis, systemic lupus erythematosus, psoriatic arthritis, ankylosing spondylitis, inflammatory bowel disease)
HIV infection
Erectile dysfunction
Chronic obstructive pulmonary disease (COPD)
All women with a history of pregnancy complications (e.g., hypertensive disorder of pregnancy, gestational diabetes, preterm birth, stillbirth, low-birth-weight infant, or placental abruption)
What will make you suspect hypercholesteremia?
Adult with a total cholesterol level greater than 7.5 mmol/L (290 mg/dL) or LDL cholesterol (LDL-C) greater than 4.9 mmol/L (190 mg/dL).
Child under 16 years with total cholesterol greater than 6.7 mmol/L (260 mg/dL) or LDL-C greater than 4.0 mmol/L (155 mg/dL).
Presence of physical signs such as tendon xanthomas, xanthelasmas, or corneal arcus, especially before age 60.
Family history of premature cardiovascular disease, such as myocardial infarction or coronary heart disease before age 55 in men or 65 in women in first-degree relatives.
Family history of elevated cholesterol levels meeting the above thresholds in first- or second-degree relatives.
Genetic testing revealing mutations in LDL receptor gene (LDLR), apolipoprotein B (apoB), or PCSK9 genes.
Diagnostic criteria such as the Simon Broome, Dutch Lipid Clinic Network Criteria (DLCN), or MedPed score integrate these elements including lipid levels, family history, physical signs, and genetic testing to classify FH as definite or probable.
In summary, suspicion should arise with markedly elevated LDL-C or total cholesterol, relevant family history of premature cardiovascular disease or hypercholesterolemia, and clinical findings like tendon xanthomas or corneal arcus, even if genetic confirmation is pending or absent.

Task 3
When will u consider prescribing statins regardless of CVD risk?
It is strongly recommended with high level.of evidence that adults with 40 t0 70 years of age, with diabetes ,regardless of estimated 10 years ASCVD risk,moderate intensity statin theraphy is indicated
It is strongly recommended but with moderate quality evidence that in patients 20 t0 75 years of age,with an LDL- C level of 190 mg /dl (>_4.9mmol/L) or higher, maximally tolerated statin therapy is indicated.
