Non St Elevasyonlu Akut Koroner Sendromlarda Risk Sınıflaması ve Girişim Zamanı

Volkan Doğan, Özcan Başaran, Murat Biteker

Özet


Akut koroner sendrom (AKS) terimi koroner plak yırtılması sürecinde oluşan iskemik durumların bütününü tanımlamak için geliştirilmiştir. ST yükselmesi olmayan AKS’ler; ST yükselmesi olmayan, ancak hasar belirteçlerinde yükselme ile ispat edilmiş miyokard hasarı bulunanlar [ST yükselmesi olmayan miyokard infarktüsü (NSTEMI)] ve kararsız anjinalı (unstable angina; UA) hastalar olarak iki gruba ayrılır. UA ve NSTEMI AKS’lerin sebebi genellikle aterosklerotik hastalıktır. Ortak bir patofizyolojiyi paylaşabilirler ve ilk sunu sırasında birbirinden ayırt edilemeyebilirler; risk tabakalandırması yaklaşımı ve tedavi aynıdır ve bu sendromlar sadece kardiyak biyobelirteçlerde yükselme olup olmaması ile ayırt edilirler. Bu derlemede, NSTEMI hastalarında kullanılan risk sınıflamaları ve invazif tedavi zamanlaması tartışılacaktır.

Anahtar kelimeler: Akut koroner sendrom, invazif tedavi zamanlaması, risk sınıflaması, ST elevasyonsuz miyokard infarktüsü
