## Content

Published in *PNAS*, March 17, 2020. NCI researchers. This is the foundational paper establishing that CVD stagnation — not drug deaths — is the primary driver of US life expectancy plateau.

**Key findings:**
- CVD stagnation held back US life expectancy at age 25 by **1.14 years in both women and men** between 2010 and 2017.
- Rising drug-related deaths had a much smaller effect: **0.1 years in women and 0.4 years in men.**
- Ratio: CVD stagnation effect is approximately 3–11x larger than drug mortality effect on life expectancy.
- The stagnating decline in CVD mortality was "the main culprit outpacing and overshadowing the effects of all other causes of death."

Context: This paper was published before the 2026 PNAS cohort analysis but establishes the primary mechanism. The 2026 cohort paper (Abrams & Bramajo) extends this finding by showing the same CVD-driven pattern operates at the cohort level with a distinct 2010 period effect.

## Agent Notes
**Why this matters:** This is the key mechanism paper for the disconfirmation search. The opioid epidemic was the popular narrative for US mortality stagnation; this paper shows CVD is 3-11x more impactful. Since CVD/metabolic decline is structural (not reversible like opioid epidemic), this STRENGTHENS Belief 1's "binding constraint" framing.
**What surprised me:** The magnitude of the ratio — CVD effect is 3-11x drug deaths effect. Most public discourse attributes the stall to opioids. The actual driver (CVD/metabolic) gets far less attention.
**What I expected but didn't find:** Opioid mortality being the primary driver. The data contradicts the popular narrative.
**KB connections:** Directly relevant to any claim about structural health deterioration; connects to "deaths of despair" claims; links to food industry and metabolic disease claims.
**Extraction hints:** "US life expectancy stagnation is driven primarily by CVD plateau (1.14 years lost), not drug deaths (0.1-0.4 years lost) — a 3-11x difference that inverts the dominant public narrative."
**Context:** Published 2020, now confirmed and extended by 2025-2026 literature. The 2010 CVD stagnation pattern was visible even in 2020 data. This is not a new phenomenon — it's been building for 15 years.

## Curator Notes
PRIMARY CONNECTION: PNAS 2026 Abrams-Bramajo cohort paper (already archived); provides mechanism for 2010 period effect
WHY ARCHIVED: Foundational mechanism paper establishing CVD>drugs as life expectancy driver; frequently cited in subsequent literature
EXTRACTION HINT: Quantitative claim: "CVD stagnation costs 1.14 life expectancy years vs. 0.4 years for drug deaths — inverting the public narrative about opioids as the health crisis driver."
