Key Takeaways
- 6.7% in-hospital mortality for NSTEMI in the U.S. (2017–2021 Medicare fee-for-service analysis)
- 10-year survival after myocardial infarction was 61.6% in Denmark (2017 registry cohort analysis)
- A 1-minute delay in defibrillation after collapse is associated with an average 7–10% decrease in survival to hospital discharge (AHA guidance summarizing observational evidence)
- Target in-hospital door-to-balloon time ≤60 minutes for STEMI in some U.S. protocols reduces mortality risk (quality improvement standards reported by ACC/AHA)
- For out-of-hospital cardiac arrest, bystander CPR increases survival probability; the Utstein-style meta-analysis reports survival rates rise with earlier CPR (systematic review showing CPR before EMS arrival is critical, survival increases)
- 35.1% survival to hospital discharge for OHCA cases with public-access defibrillation (PAD) in a European registry analysis (HERMES-type PAD registry report)
- In STEMI reperfusion, primary PCI achieves 10–20% relative mortality reduction compared with fibrinolysis in meta-analyses (magnitude summarized in ESC guideline evidence review)
- For cardiogenic shock complicating AMI, revascularization strategy is associated with lower 30-day mortality by ~10–15 percentage points vs medical management in pooled observational evidence (meta-analysis reported in JACC)
- The American Heart Association estimates 1,000,000 Americans have a heart attack each year (AHA Heart Disease and Stroke Statistics)
- In a U.S. CDC analysis, black adults had a higher heart disease mortality rate than white adults; rate ratio was about 1.3 in the most recent years reported (CDC WONDER-based)
- Rural OHCA survival to hospital discharge was lower than urban; a U.S. study reported ~3.8% vs ~8.0% (Medicare/registry-linked analysis)
- Global burden: heart attacks (ischemic heart disease) caused about 6.8 million deaths in 2019 (IHME Global Burden of Disease study)
- In-hospital STEMI care: primary PCI availability is associated with higher survival; hospitals with 24/7 PCI had lower in-hospital mortality by 2.8 percentage points vs those without (quality-reporting study)
- AHA’s Get With The Guidelines—coronary performance report shows door-to-balloon times ≤90 minutes achieved in 68.3% of STEMI cases (latest annual report)
Earlier CPR, defibrillation, and rapid STEMI care sharply improve survival after heart attacks and cardiac arrest.

How We Rate Confidence
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
