A abla\u00e7\u00e3o por cateter tem sido proposta como estrat\u00e9gia para restaurar o ritmo sinusal; entretanto, seus efeitos sobre a FEVE permanecem heterog\u00eaneos na literatura. Avaliar o impacto da abla\u00e7\u00e3o por cateter, em compara\u00e7\u00e3o \u00e0 terapia medicamentosa, sobre a FEVE em pacientes com FA e ICFEr. Revis\u00e3o sistem\u00e1tica de ensaios cl\u00ednicos randomizados conduzida de acordo com as diretrizes PRISMA. O desfecho prim\u00e1rio foi a melhora da FEVE, enquanto os desfechos secund\u00e1rios inclu\u00edram mortalidade cardiovascular, mortalidade por todas as causas e hospitaliza\u00e7\u00f5es por IC. Outros desfechos explorat\u00f3rios tamb\u00e9m foram considerados. Os ensaios cl\u00ednicos inclu\u00eddos demonstraram melhora da FEVE em pacientes submetidos \u00e0 abla\u00e7\u00e3o por cateter quando comparados \u00e0 terapia medicamentosa. No estudo CAMERA-MRI, foi observado aumento absoluto de 18,3% na FEVE ap\u00f3s seis meses. No estudo CASTLE-AF, a abla\u00e7\u00e3o tamb\u00e9m se associou a menor ocorr\u00eancia de mortalidade cardiovascular e hospitaliza\u00e7\u00f5es por IC. Contudo, devido \u00e0 aus\u00eancia de metan\u00e1lise, n\u00e3o foi realizada s\u00edntese quantitativa dos efeitos. Os estudos sugerem que a abla\u00e7\u00e3o por cateter pode estar associada \u00e0 melhora da FEVE e a desfechos cl\u00ednicos mais favor\u00e1veis em pacientes com FA e ICFEr. Entretanto, devido \u00e0 aus\u00eancia de s\u00edntese quantitativa, esses achados devem ser interpretados com
