Cardiomyopathy is rare at the level of individual diagnoses, yet it drives millions of clinical decisions and outcomes worldwide, including an estimated 1.9 million deaths from cardiomyopathy and myocarditis in 2019. In 2020, restrictive cardiomyopathy alone affected an estimated 6.8 million people globally, while the UK’s hypertrophic cardiomyopathy prevalence was about 0.16 percent. As guideline thresholds, imaging biomarkers, and new drug approvals keep shifting, these rates and risks help explain why two patients with similar symptoms can end up on very different care pathways.
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.

Clinical Guidelines & Diagnosis Interpretation
Across major Clinical Guidelines and Diagnosis updates, cardiomyopathy care is increasingly standardized around clear diagnostic and risk thresholds such as an LV wall thickness of at least 13 mm in hypertrophic cardiomyopathy and LVEF 35% or less for ICD primary prevention, while newer guidance adds precision tools like cardiac MRI fibrosis detection and amyloidosis and myocarditis pathways.
