Abstract

Objective: Aim of the present study was to determine effects of high-dose versus low-dose intravenous (IV) bolus tirofiban on angiographic measures, ST resolution, enzymatic infarct size, and clinical outcomes in patients with acute coronary syndrome (ACS) who were undergoing percutaneous coronary intervention (PCI) and received current pharmacoinvasive therapy. Methods: Acute coronary syndrome patients (n=271, 85.6% male; mean age: 57.9±12.6 years) from between 2009 and 2015 who received IV tirofiban therapy following PCI were retrospectively analyzed. All patients had received maintenance tirofiban infusion (0.15 μg/kg/min) after bolus dose and 600 mg clopidogrel. Percentage of patients undergoing drug eluting stent implantation procedure was 33.5%. Tirofiban was administered to all patients in bailout situation or for thrombotic complication after PCI. Results: High-dose IV bolus group (25 μg/kg; n=140) was associated with greater ST segment resolution (66% vs. 50%, p=0.013) and reduced peak troponin release [12.4 ng/dL (range: 6.5–21.5 ng/dL) vs. 16.4 ng/dL (range: 10.1–27.4 ng/dL), p=0.001] compared with low-dose bolus group (10 μg/kg, n=131). Cardiovascular event rates were similar between groups at in-hospital, 1-month, and 6-month follow-up (p=1.000, 1.000, and 0.287, respectively). Percentage of patients with post-procedural Thrombolysis in Myocardial Infarction (TIMI) grade III flow, major, and minor bleeding were similar (p=0.085, 1.000, and 0.965, respectively). Conclusion: Use of high-dose IV bolus tirofiban in addition to aspirin and high-dose clopidogrel improves ST segment resolution, reduces infarct size, and does not increase bleeding events in patients with ACS undergoing PCI compared with low-dose bolus. Angiographic measures and clinical endpoints were similar between groups

Özet

Amaç: Güncel farmakoinvaziv tedavi uygulanan ve perkütan koroner girişime (PKG) alınan akut koroner sendromlu (AKS) hastalarda intravenöz (İV) düşük yükleme dozuna karşılık yüksek yükleme dozunda tirofibanın anjiyografik ölçümler, ST segment rezolüsyonu, enzimatik enfarkt büyüklüğü ve klinik sonlanımlar üzerine etkilerini belirlemeyi amaçladık. Yöntemler: 2009 ile 2015 yılları arasında PKG sonrası İV tirofiban tedavisi alan AKS'li 271 hasta (%85.6 erkek, ortalama yaş: 57.9±12.6) geriye dönük olarak incelendi. Tüm hastalar yükleme dozunun ardından sürdürme dozunda tirofiban infüzyonu (0.15 ?g/kg/dk) ve 600 mg klopidogrel aldı. İlaç kaplı stent takılan hastaların oranı %33.5 idi. Tirofiban tüm hastalarda kurtarıcı amaçlı ya da trombotik komplikasyon varlığında PKG'den sonra verildi.Bulgular: İntravenöz yüksek yükleme dozunda tirofiban uygulanan grupta (25 ?g/kg, n=140), düşük yükleme dozu alanlara göre (10 ?g/kg, n=131) ST-segment rezolüsyonu daha fazla (%66 ve %50, p=0.013) ve pik troponin salınımı daha azdı (12.4 ng/dL [dağılım: 6.5-21.5 ng/dL] ve 16.4 ng/dL [dağılım: 10.1-27.4 ng/dL], p=0.001). Hastane içi, bir ay ve altı aylık takiplerde kardiyovasküler olay oranları gruplar arasında benzerdi (sırasıyla, p=1.000, 1.000 ve 0.287). İşlem sonrası Thrombolysis in Myocardial Infarction (TIMI)-3 akımı olan hasta oranı, majör ve minör kanama oranları gruplar arasında benzerdi (sırasıyla, p=0.085, 1.000 ve 0.965).Sonuç: Aspirin ve yüksek doz klopidogrele ilaveten yüksek yükleme dozunda İV tirofiban uygulamasının PKG'ye alınan AKS'li hastalarda düşük yükleme dozuna kıyasla ST-segment rezolüsyonunu iyileştirme ve enzimatik enfarkt büyüklüğünü azaltmada kanama olaylarını artırmaksızın daha etkin olduğu gösterildi. Anjiyografik ölçümler ve klinik sonlanımlar gruplar arasında benzerdi
