Nature Cardiovascular Research is a peer-reviewed, open-access journal from the Nature Portfolio that publishes cutting-edge research in cardiovascular science, spanning molecular and cellular mechanisms, clinical studies, and translational work. It highlights major advances such as cell-type specific atlases of diseased hearts, immune-system contributions to cardiac injury, and regeneration of cardiac conduction systems in neonatal models. With its broad remit—from basic biology to potential therapies—it aims to accelerate understanding and improve outcomes in cardiovascular disease.
