Long-term cardiovascular sequelae of COVID-19 in patients with pre-existing heart failure: a systematic review

Patients with pre-existing heart failure (HF) are particularly vulnerable to adverse outcomes following coronavirus disease 2019 (COVID-19). Understanding of the long-term cardiovascular sequelae of COVID-19 in this high-risk group is essential to improve post-infection management and outcomes.

A systematic review of PubMed, Scopus, Web of Science, and Embase was conducted to identify peer-reviewed studies published between 2020 and 2025. Eligible studies included adults with a confirmed diagnosis of HF prior to COVID-19 infection and reported cardiovascular outcomes assessed at least 12 weeks after the acute phase. Data were extracted on patient demographics, HF subtype, cardiovascular outcomes, quality of life (QoL), and management approaches.
