Statins are prescription medicines that lower cholesterol-carrying particles in the blood. Trial evidence shows fewer heart attacks, clot-type strokes, and heart-related deaths, especially after a first heart attack or stroke and when starting particle levels are high. They are an artery-protection tool, not a general vitality medicine. Costs include a small blood-sugar rise and muscle symptoms. (Full Review)
| Marker | Target | Why |
|---|---|---|
| Apolipoprotein B | 20–60 mg/dL for aggressive prevention; many clinics use <80 | Particle number that enters artery walls |
| LDL cholesterol | <70 mg/dL high-risk; <55 mg/dL very-high-risk | Common surrogate for apolipoprotein B |
| Lipoprotein(a) | <30 mg/dL or <75 nmol/L | Inherited residual particle risk; statins can raise it |
| High-sensitivity C-reactive protein | <0.5–1.0 mg/L | Residual inflammatory risk on treatment |
| Hemoglobin A1c | <5.3–5.5% | Detect the statin-associated glucose shift |
| Fasting insulin | <5–8 μIU/mL | Early insulin resistance before hemoglobin A1c moves |
| Alanine aminotransferase | Near personal baseline; generally <30–40 U/L | Liver-enzyme signal |
| Creatine kinase | Personal baseline; investigate symptoms plus a large rise | Muscle injury |
| Thyroid-stimulating hormone | About 0.5–2.5 mIU/L in functional practice | Hypothyroidism raises LDL and mimics myalgia |
| Fasting glucose | Pair with fasting insulin | Glucose reserve and the diabetes shift |
| Coronary artery calcium scan | When it would change intensity | Whether plaque is already present |
Cadence: Baseline before the first dose; 6–8 weeks (lipids, apolipoprotein B, enzymes, glucose); 3–6 months; then every 6–12 months if stable; sooner after dose changes or new muscle symptoms
