Question

What are the troponins and their importance in the diagnosis and prognosis of heart failure?

I - Troponins are a set of structural and regulatory proteins that participate in the contractile function of skeletal and cardiac muscle tissue.
II - Troponins T and I are considered prognostic markers of decompensated heart failure.
III - The troponin should be dosed to exclude acute myocardial infarction in cases of acute heart failure.
IV - The troponin is a sensitive and specific marker of myocardial injury and is also a predictor of prognosis and stratification of heart failure.

Ed · Answer

As troponinas são um conjunto de proteínas estruturais e regulatórias que participam da função contrátil do tecido muscular esquelético e cardíaco. As troponinas T e I são consideradas marcadores prognósticos de insuficiência cardíaca descompensada. A troponina deve ser dosada para excluir infarto agudo do miocárdio em casos de insuficiência cardíaca aguda. A troponina é um marcador sensível e específico de lesão miocárdica e também é um preditor de prognóstico e estratificação da insuficiência cardíaca. Portanto, as alternativas corretas são II, III e IV.
