Amaç
Biz bu çalışmamızda akut koroner sendromlu olgularda çok damar hastalığı saptanan durumlar da şok indeksinin hastane içi mortalite üzerine olan etkisini değerlendirmek istedik.
Yöntem ve Gereçler
Çalışmamıza akut koroner sendrom tanısı alan, çok damar hastalığı saptanan ve koroner anjiyografi ve primer perkütan koroner girişim ya da koroner arter by-pass cerrahisi yolu ile tedavi edilen 623 hasta dahil edildi. Şok indeksi kalp hızını sistolik kan basıncına bölerek hesaplandı.
Bulgular
Mortalite saptanan olgularda istatistiksel olarak kan basıncı daha düşüktü ve kalp hızı diğer gruba kıyasla daha yüksekti (p<0,001). Çok değişkenli Cox regresyonan alizinde yaş, düşük sol ventrikül ejeksiyon fraksiyonu, yüksek anatomik SYNTAX skoru ve şok indeksi hastane içi ölüm için öngördürücü olarak bulundu. Alıcı işletim karakteristik eğrisi analizinde şok indeksinin yeterli derecede mortalite öngördürücü istatistiksel gücü olduğu tesbit edildi (eğri altındaki alan: 0,711, %95 güven aralığı: 0,632-0,789, p<0,001).
Sonuç
Şok indeksi akut koroner sendromlu çok damar hastalığı olgularında mortalite öngördürücüsü olarak saptanmıştır.
Anahtar Kelimeler: Şok indeks, akut koroner sendrom, mortalite
