# CVD mortality stagnation drives US life expectancy plateau 3-11x more than drug deaths inverting the dominant opioid crisis narrative

NCI researchers quantified the contribution of different mortality causes to US life expectancy stagnation between 2010 and 2017. CVD stagnation held back life expectancy at age 25 by 1.14 years in both women and men. Rising drug-related deaths had a much smaller effect: 0.1 years in women and 0.4 years in men. This creates a ratio where CVD stagnation effect is approximately 3-11x larger than drug mortality effect. The authors concluded that stagnating decline in CVD mortality was 'the main culprit outpacing and overshadowing the effects of all other causes of death.' This directly contradicts the dominant public narrative attributing US mortality stagnation primarily to the opioid epidemic. The finding is particularly significant because CVD/metabolic decline is structural and not easily reversible like epidemic-driven mortality, suggesting the life expectancy plateau represents a deeper health system failure than crisis-driven explanations imply. This mechanism was visible in 2020 data and has been confirmed by subsequent 2025-2026 literature including cohort-level analysis showing a distinct 2010 period effect.
