Trends in Heart Failure Prevalence in Japan 2014–2019: A Report from Healthcare Administration Databases
Authors' conclusion
We estimated that the prevalence of HF in Japan was 2.2-3.7% for patients aged ≤74 during the period 2014-2019 using the JMDC database, while the prevalence for patients of all ages was 6.5% using the MDV database.
