To highlight the association between respiratory viral infections (RVIs), including influenza, COVID-19, and RSV, and the increased risk of heart failure (HF), emphasizing the importance of vaccination as a preventive strategy.
Key Findings:
RVI hospitalizations were linked to a 45% increased risk of new-onset HF in previously unaffected individuals (aHR 1.45).
RSV was identified as a particularly high-risk pathogen for new-onset HF (aHR 2.03).
Vaccination against influenza and COVID-19 was associated with a reduced risk of HF events (HR 0.86 for influenza).
Interpretation:
The findings suggest that RVIs significantly increase the risk of heart failure, and vaccination can mitigate this risk, highlighting the urgent need for improved vaccination strategies in at-risk populations.
Limitations:
The study's retrospective nature may limit causal inferences and introduce biases.
Vaccine uptake among patients with HF remains low, indicating a gap in preventive care.
Conclusion:
Vaccination should be prioritized as a cardiovascular preventive strategy, particularly for older adults and those with existing health vulnerabilities, to urgently reduce the burden of heart failure.
