Objetivo: Desenvolver um escore de risco para prever hemorragia em pacientes no p\u00f3s-operat\u00f3rio de cirurgia valvar.  M\u00e9todos: Estudo retrospectivo de pacientes submetidos a cirurgia valvar entre 2021 e 2022 no IDPC. Pacientes com sangramento maior foram selecionados com base nos crit\u00e9rios de BARC e Bojar. Foi realizada uma an\u00e1lise de regress\u00e3o log\u00edstica para fatores relacionados ao sangramento e foi criado um nomograma. Para signific\u00e2ncia estat\u00edstica, foram considerados p&lt;0,05 e um intervalo de confian\u00e7a de 95%. O estudo foi aprovado pelo CEP.  Resultados: Foram analisados 525 pacientes com idade m\u00e9dia de 56 anos e predom\u00ednio do sexo feminino. A valvopatia mais comum foi a insufici\u00eancia mitral, 8,8% apresentaram sangramento aumentado e houve 4,3% de reabordagens cir\u00fargicas. As vari\u00e1veis com signific\u00e2ncia estat\u00edstica foram: insufici\u00eancia tric\u00faspide (OR 3,31, p &lt; 0,001), doen\u00e7a renal cr\u00f4nica\/les\u00e3o renal aguda (OR 2,97, p = 0,006), hemoglobina pr\u00e9-operat\u00f3ria (OR 0,73, p &lt; 0,001), reopera\u00e7\u00f5es (OR 2,5, p = 0,003), tempo de circula\u00e7\u00e3o extracorp\u00f3rea (CEC) (OR 1,12, p &lt; 0,001), abordagem de 2 valvas OR de 2,23 (p = 0,013), uso de concentrado de hem\u00e1cias OR de 2,8 (p = 0,001). No modelo m\u00faltiplo a insufici\u00eancia tric\u00faspide, tempo de CEC e hemoglobina pr\u00e9-operat\u00f3ria alcan\u00e7aram signific\u00e2ncia estat\u00edstica.  Conclus\u00e3o: O tempo de CEC, hemoglobina pr\u00e9-operat\u00f3ria e insufici\u00eancia tric\u00faspide associaram-se independentemente com hemorragia p\u00f3s-operat\u00f3ria. A escala proposta \u00e9 plaus\u00edvel, e pode auxiliar na predi\u00e7\u00e3o de risco de sangramento.<\/jats:p>","DOI":"10.36660\/abc.20230453","type":"journal-article","created":{"date-parts":[[2024,11,1]],"date-time":"2024-11-01T10:23:36Z","timestamp":1730456616000},"source":"Crossref","is-referenced-by-count":0,"title":["Fatores
