Abstract

Objective: ST-segment elevation myocardial infarction (STEMI) is an important cause of morbidity and mortality. Platelet (PLT) activation and thrombosis have important roles in the process of atherosclerosis that is one of the most important cause of acute ischaemic syndromes. PLT count is related with inflammation and mean platelet volüme (MPV) is an important marker of PLT activation. Both parameters are found to be related with increased cardiovascular risk. In this study we aimed to investigate clinically usability of a new parameter:MPV/PLT ratio, in the diagnosis of patients with Troponin I elevated STEMI.Material and Methods:92 male patients with STEMI-underwent percutaneous coronary intervention (PCI) successfully and 75 healthy subjects were enrolled in the study. T-test was used to determine significant differences between the groups for data with normal distribution and Spearman’s analysis was used to deterMIne the correlations between the variables. Independent predictive factors were found for PLT, MPV and MPV/PLT ratio of patients with STEMI.Characteristic ROC curves were performed, optimal cut-off points were determined.Results: Significant differences were determined for PLT, MPV and MPV/PLT ratio levels of patients (P

Özet

Amaç: ST- segment yüksekliği olan Miyokard enfarktüsü (STEMI) morbidite ve mortalitenin önemli bir nedenidir. Platelet (PLT) aktivasyonu ve tromboz akut iskemik sendromların önemli nedenlerinden biri olan ateroskleroz sürecinde önemli rollere sahiptir. PLT sayısı enflamasyon ile ilişkilidir ve ortalama platelet hacmi (MPV) PLT aktivasyonunun önemli bir belirtecidir. Her iki parametre de artmış kardiyovasküler risk ile ilişkili bulunmuştur. Bu çalışmada Troponin I yüksekliği olan STEMI hastalarının klinik tanısında yeni bir parametre olan MPV/PLT oranının klinik kullanılabilirliğini araştırmayı amaçladık.Gereç ve Yöntem: Başarılı primer perkütan koroner girişim (PKG) uygulanan STEMI hastası 92 erkek hasta ve 75 kontrol erkek katılımcı çalışmaya dahil edildi. Gruplar arasındaki normal dağılımlı değişkenler için t-test, her bir grubun değişkenler arası korelasyonları için Spearman analizi yapıldı. STEMI hastalarının PLT, MPV ve MPV/PLT oranı parametreleri için bağımsız prediktif faktörleri bulundu.Karakteristik ROC eğrileri oluşturuldu ve optimal cut-off değerleri saptandı. İstatistiksel analizler için SPSS 21.0 programı kullanıldı.Bulgular: Hastaların PLT, MPV ve MPV/PLT oranı düzeyleri arasında yüksek anlamlı ilişki saptandı (P< 0.001). PLT için optimal kesim değeri 262.5 (EAA 0.488, duyarlılık %50 ve özgüllük %52); MPV için 10.45 (EAA 0.700, duyarlılık %69 ve özgüllük %54); ve MPV/PLT için 0.043 (EAA 0.778, duyarlılık %71 ve özgüllük %64) olarak bulundu.Sonuç: MPV/PLT oranının STEMI’lı hastalarda PLT ve MPV değerlerinden daha sensitif ve spesifik olduğu gösterildi. Ayrıca yükselmiş MPV/PLT oranı yüksek SYNTAX skoru ile ilişkili idi. MPV/PLT oranının bu hastaların ciddiyetinin değerlendirilmesinde yarar sağlayabileceğini önermekteyiz
