ADVICE

Use Coronary Imaging To Personalize Treatment

  • Use cardiac imaging to personalize statin decisions rather than relying on LDL alone.
  • Norwitz suggests coronary artery calcium or CT angiography can reveal plaque burden and may justify avoiding statins even with very high LDL.
INSIGHT

Null Results Don't Prove Absence Of Harm

  • Meta-analyses reporting 'no side effects' can mask trends toward harm that don't cross statistical thresholds.
  • Norwitz critiques a Lancet statin meta-analysis that found many non-significant trends and presented results in confusing plots, cautioning against overconfident headlines.
ADVICE

Give CoQ10 And Consider TUDCA With Statins

  • Supplement CoQ10 and consider TUDCA if you take statins to counter mitochondrial and GLP‑1/bile acid effects.
  • Norwitz recommends a phytosome CoQ10 for absorption and TUDCA/UDCA as potentially helpful adjuncts.
