Vantagens e desvantagens dos stents coronarianos com drogas e sem drogas

Por Prof. Wagner Silva Dantas

Stents sem drogas ( convencionais ) : suas principais vantagens são o seu preço ( bem inferior aos stents com droga ) e a menor possibilidade de formação de coágulos tardios ( trombose tardia do stent ). A sua principal desvantagem é que este tipo de stent é menos efetivo no combate da reestenose .

Stents com drogas ( farmacológicos ) : sua principal vantagem é o baixo índice de reestenose. Suas desvantagens são o seu preço e uma maior possibilidade de formação de coágulos tardios ( trombose tardia do stent ). Por esse fato , exigem o uso preferencial de dois medicamentos para evitar a agregação das plaquetas no sangue , usados por pelo menos um ano ( o ácido acetilsalicílico e o clopidogrel ). Devem ser indicados em pacientes com maior risco de reestenose, como os diabéticos , portadores de placas de ateroma longas e em artérias finas.
