The NiCARDIA registry is a prospective observational cohort designed to evaluate long-term functional trajectories in 8,500 adults hospitalized with cardiovascular disease.

The NiCARDIA registry will link hospital-based clinical data with population-level administrative datasets to comprehensively evaluate long-term functional trajectories and their determinants in contemporary cardiovascular patients in Japan.
Background: As populations age, cardiovascular disease (CVD) increasingly affects functional independence, an issue of growing importance among older adults. However, long-term trajectories of functional decline in patients receiving contemporary CVD care remain poorly characterized, so the Niigata Cardiovascular Disease Registry using Health Insurance Claims (NiCARDIA) was established to address this gap by integrating hospital-based clinical data with administrative datasets through a prefecture-wide data-sharing platform.
Fujiki et al. (2026) conducted an observational in Cardiovascular disease (n=8,500). Hospitalization for cardiovascular disease was evaluated on Longitudinal change in functional independence assessed by certified long-term care-need levels. The NiCARDIA registry is a prospective observational cohort designed to evaluate long-term functional trajectories in 8,500 adults hospitalized with cardiovascular disease.
