Resumo

A expansão e descoberta de novas possibilidades de diagnóstico para o uso de muitos biomarcadores de doenças cardiovasculares( DCV), incluindo isoformas cardioespecíficas de troponina (cTnI, cTnT), é devido à melhoria dos métodos laboratoriais para sua determinação. Ao longo de uma longa história da criação e melhoria de métodos imunoquímicos para a determinação de cTnI e cTnT, mudanças significativas foram observadas no conceito de biologia e seu valor diagnóstico como biomarcadores de DCV. Os métodos obsoletos de detecção de cTnI, cTnT, chamados de baixa e moderada sensibilidade, foram distinguidos por uma sensibilidade relativamente baixa, o que levou à confirmação tardia do diagnóstico de infarto agudo do miocárdio (IAM) e, portanto, esses métodos foram gradualmente substituídos por novos métodos de alta e moderada sensibilidade, como definições de métodos ultra-sensíveis (hs-cTnI, hs-cTnT). Com a introdução de hs-cTnI e hs-cTnT na prática clínica, a possibilidade de diagnóstico precoce e exclusão do IAM mediante a avaliação da cinética da concentração de hs-cTnI e hs-cTnT nas primeiras horas (0-1 hora, 0-2 horas, 0-3 horas) desde o momento em que o paciente entra em urgências. Além disso, algumas de nossas idéias sobre a biologia das troponinas cardíacas mudaram e surgiram novas oportunidades promissoras para uso em medicina. Este artigo discute as principais características analíticas dos métodos de detecção de hs-cTnI e hs-cTnT em comparação com métodos moderadamente sensíveis, e relata novos dados biológicos e algumas novas possibilidades de diagnóstico para o uso de hs-cTnI e hs-cTnT na prática clínica moderna.
