A cintilografia de perfusão do miocárdio (CPM) é útil para detectar o grau e a localização do defeito de perfusão miocárdica, pois auxilia no manejo clínico de doença arterial coronariana (DAC). Tal ato permite uma avaliação mais específica para pacientes que sofrem de alguma síndrome coronariana aguda (SCA), haja visto que está diretamente relacionado à permeabilidade das artérias coronarianas e sua obstrução. Objetivo: Investigar, interpretar e revisar os achados sobre Cintilografia de Perfusão do Miocárdio (CPM), relacionando a validade do exame em pacientes com Síndrome Coronariana Aguda. Metodologia: Utilizou-se a base Medical Literature Analysis and Retrieval System Online (MEDLINE/PubMed), sob os descritores Cintilografia miocárdica; Síndrome Coronariana Aguda, com seleção de artigos de revisão e artigos originais, seguindo critérios de elegibilidade. Foram encontrados 518 textos, com seleção inicial de 107, dos quais restaram 48 artigos elegíveis. Resultados: Os artigos redigidos em língua inglesa contemplavam também publicações de autores e periódicos de diferentes nacionalidades. A maioria dos artigos abrangiam os anos de 2020 (14). Considerações finais: O uso da CPM é uma alternativa promissora para a terapêutica do manejo de SCA, pois estima auxilia no diagnóstico e estratificação de risco, principalmente em pacientes com SCA sem supradesnivelamento do segmento ST. Ademais, pacientes com dor torácica típica que procuram o pronto socorro para o alívio de sua dor tem possibilidade de avaliar a possibilidade de alguma DAC com esse exame, assim com melhor identificação da etiologia da sua dor, conseguirá um acompanhamento mais eficaz para evitar piores desfechos da doença.
