Objetivo: avaliar o impacto do ultrassom à beira-leito (POCUS) na acurácia diagnóstica e no tempo até a definição da conduta em adultos atendidos no pronto-socorro com suspeita de insuficiência cardíaca aguda (ICA). Método: revisão integrativa, com questão estruturada pelo PICO, realizada nas bases MEDLINE/PubMed, Scopus, Web of Science, Embase e LILACS/BVS, incluindo estudos completos publicados entre 2016–2026. Resultados: os estudos incluídos indicam que o POCUS, sobretudo o ultrassom pulmonar isolado e/ou protocolos combinados coração-pulmão-veia cava inferior, aumenta a capacidade de confirmar ICA (alta especificidade, com sensibilidade variável conforme protocolo e contexto clínico) e reduz o tempo para esclarecimento diagnóstico e direcionamento da conduta; em coorte com dispneia aguda, houve redução do tempo até diagnóstico de 3 h 28 min para 21 min. Conclusão: a incorporação do POCUS à avaliação clínica no pronto-socorro tende a melhorar a tomada de decisão e o fluxo assistencial, sendo recomendável padronização de protocolos e treinamento para mitigar variabilidade operador-dependente.
