Unraveling Attenuated Risk Factor Associations in Secondary Coronary Prevention: Implications for Clinical Practice

Highlight
- Risk factor associations for subsequent coronary events are systematically weaker compared to first events, a phenomenon attributed to index event bias.
- A 10-year primary prevention risk model performs well for first coronary events but poorly predicts recurrent events after initial coronary heart disease (CHD).
- Some traditional risk factors exhibit paradoxical or neutral associations post-first event, complicating risk interpretation in secondary prevention.
- Findings caution against deprioritizing established therapies, such as LDL cholesterol lowering, based on attenuated risk factor associations in CHD survivors.
