Cardiomyopathy is the most common inherited cardiovascular disease, showing family aggregation, and it has a huge psychological and economic burden on family members. In this study, the investigators collected clinical information and costs of patients hospitalized with cardiomyopathy and establish a database to characterize real-world cost profile and inform cost management of cardiomyopathy.

This study conducted a retrospective survey of hospitalized patients with cardiomyopathy aged ≥18 years in 13 centers in China from March 1, 2017 to March1, 2022. The investigators collected clinical information, healthcare utilization and cost data of patients hospitalized with cardiomyopathy so as to characterize real-world cost profile and inform cost management of cardiomyopathy in China.

Inclusion Criteria:

• Hospitalized patients with primary discharge diagnosis meeting one of the following subtypes of cardiomyopathy were enrolled, including HCM, DCM, ACM, RCM, left ventricular non-compaction, cardiac amyloidosis, Fabry disease, Pompe disease, Danon disease, and PRKAG2 cardiac syndrome.

Exclusion Criteria:

• Records with a "likely" or "probable" diagnosis of cardiomyopathy were excluded.

Patients hospitalized with cardiomyopathy as the primary discharge diagnosis are recruited retrospectively from multiple centers in China between March 1, 2017 and March 1, 2022.
