While the role of plasma renin activity (PRA) in heart failure has been widely studied in adults, comprehensive data on pediatric heart failure remain lacking. This drawback is increasingly being addressed by academic research. Nevertheless, such pediatric investigations are commonly conducted only once due to ethical constraints.
