Abstract

Recent studies suggest that statins have anti-arrhythmic effects. The aim of this study was to evaluate the effects of statins on sustained ventricular tachycardia or ventricular fibrillation (S-VT or VF) in patients presenting with acute coronary syndrome (ACS). Methods: The population of this study consisted of consecutive patients admitted to coronary care unit. It was an observational case-controlled retrospective analysis performed on prospective cohort. From a total of 1000 patients presenting with ACS, 241 were on and 759 were not on statin. Patient demographics, clinical characteristics and previous medical treatment including statins were recorded. A S-VT or VF episode during hospitalization was accepted as endpoint. Multiple logistic regression model was performed which considered the occurrence of S-VT or VF as the response variable. Results: Sustained VT or VF occurred in 3.3% of patients in statin group and in 9% of patients in non-statin group. Univariate positive predictors of S-VT or VF were ST elevation myocardial infarction as clinical presentation, smoking and thrombolysis; univariate negative predictors of S-VT or VF were ejection fraction, use of acetylsalicylic acid before hospitalization, use of statin before hospitalization, initiation of clopidogrel at the hospital and normal coronary arteries. In the multiple logistic regression analysis, the only independent predictor of S-VT or VF was ejection fraction (OR 0.96; 95% CI 0.93 to 0.99; p=0.005). Conclusion: Our results indicate that, although the incidence of S-VT/VF was significantly lower in patients with ACS and previous statin use; statin use is not an independent predictor of the occurrence of S-VT or VF in patients presenting with ACS.

Özet

Statinlerin antiaritmik etkileri son yıllardaki çalışmalarda gösterilmiştir. Bu çalışmada, akut koroner sendromu (AKS) olan hastalarda önceden statin kullanımının sürekli ventriküler taşikardi ve ventriküler fibrilasyon (S-VT ve VF) oluşması üzerine olan etkisi değerlendirildi. Yöntemler: Akut koroner sendrom (AKS) tanısı ile müracaat eden hastalar çalışmaya dahil edildi. Prospektif kohortta gözlemsel vaka kontrollü retrospektif analiz yapıldı. Toplam 1000 hastanın arasında 241 hasta statin kullanmakta iken, 759 hasta statin kullanmamaktaydı. Hastaların demografik, klinik özellikleri ve kullanmakta oldukları ilaçlar (statin dahil) kaydedildi. Hastanede kalış süresince, sürekli VT ve VF epizodu oluşması sonlanım noktası olarak kabul edildi. Çoklu regresyon analizinde S-VT ve VF üzerine etkili faktörler değerlendirildi. Bulgular: Statin kullanan hastaların %3.3’ünde statin kullanmayan hastaların %9’unda S-VT ve VF epizodu saptandı. Klinik tanının ST elevasyonlu miyokart enfarktüsü olması, sigara içimi, trombolitik tedavi yapılmış olması, S-VT ve VF oluşması için pozitif tek değişkenli göstergeleri olarak tespit edilirken, önceden asetil salisilik asit ve statin kullanımı, hastanede klopidogrel başlanması, ejeksiyon fraksiyonu ve normal koroner arterler sürekli S-VT ve VF oluşması için negatif tek değişkenli göstergeleri olarak bulundu. Çok değişkenli lojistik regresyon analizinde sürekli S-VT ve VF oluşmasında, ejeksiyon fraksiyonunun tek bağımsız belirteç olduğu tespit edildi (OR 0.96; %95 güven aralığı 0.93-0.99; p=0.005). Sonuç: Akut koroner sendromlu hastalarda, statin alan hastalar S-VT/VF sıklığı anlamlı olarak daha düşük olsa da; statin kullanımı S-VT ve VF oluşumu için bağımsız bir belirteç değildir.
