Key Takeaways
- 6.8 million people worldwide were estimated to be living with restrictive cardiomyopathy in 2020
- HCM prevalence was estimated at 0.16% (about 1 in 625) in the population in the UK
- In a Canadian community-based study, the prevalence of HCM was reported as 1 in 500 (0.2%)
- The 2021 ESC guidelines define left ventricular wall thickness thresholds for hypertrophic cardiomyopathy including ≥13 mm with additional risk factors
- For genetic testing in hypertrophic cardiomyopathy, the 2020 AHA/ACC guideline recommends genetic counseling and testing for patients and first-degree relatives
- The 2022 AHA/ACC/HFSA heart failure guideline recommends ARNI (sacubitril/valsartan) to reduce morbidity and mortality in patients with chronic symptomatic HFrEF
- Worldwide heart failure (not cardiomyopathy-specific) market size for therapies was estimated at $44.0 billion in 2023
- In 2024, the global cardiovascular imaging market was valued at $9.6 billion (including modalities used for cardiomyopathy evaluation such as echocardiography and MRI)
- In 2020, the US had about 1.5 million adults diagnosed with cardiomyopathy-related heart failure conditions broadly classified under heart failure (context for access and burden)
- In the DAPA-HF trial, dapagliflozin reduced the primary composite outcome (worsening heart failure or cardiovascular death) by 26% versus placebo (HR 0.74)
- In the EMPEROR-Reduced trial, empagliflozin reduced the risk of the primary composite endpoint by 25% versus placebo (HR 0.75)
- In PARADIGM-HF, sacubitril/valsartan reduced cardiovascular death or hospitalization for heart failure by 20% versus enalapril (HR 0.80)
About 6.8 million people worldwide live with restrictive cardiomyopathy, while HCM affects roughly 0.16% in the UK.

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
