Cholesterol-lowering medicines that clearly cut heart attacks, strokes, and deaths in people who already have heart or artery disease; in those without it, benefit is smaller and hinges on personal risk. Main trade-offs are a modest rise in diabetes among the metabolically vulnerable and mostly expectation-driven muscle complaints. Truly dangerous reactions are rare. (Full Review)
| Marker | Target | Why |
|---|---|---|
| ApoB | <80 mg/dL (high-risk <60 mg/dL) | Best marker of atherogenic particle number and the true drug target |
| LDL cholesterol | <100 mg/dL (high-risk <70 mg/dL) | Primary treated lipid; tracks intensity of therapy |
| Lipoprotein(a) | <30 mg/dL (<75 nmol/L) | Inherited risk particle not lowered by statins |
| ALT / AST | ALT <25 (women) / <30 (men) U/L | Detect hepatotoxicity |
| Creatine kinase | Within normal; symptom-triggered | Detect muscle injury/myopathy |
| HbA1c | <5.4% | Monitor for new-onset diabetes |
| High-sensitivity CRP | <1.0 mg/L | Track residual inflammatory risk |
Cadence: Lipids at 6–12 weeks after starting or dose change, then every 6–12 months; glucose/HbA1c every 6–12 months in those at metabolic risk; liver enzymes and creatine kinase as prompted by symptoms
