Abstract

Aim: It has been known that immunologic mechanisms play important role in the development of atherosclerosis and in the pathophysiology of acute myocardial infarction (AMI). It has been considered that serum Immunglobulin E (Ig E) may have some effects on the course of AMI by means of mast cell-mediated mechanisms. In this study, the effects of the serum Ig E levels on the in-hospital clinical course of AMI, on the infarct size and on the atherosclerotic vessel involvement were investigated. Material and Method: Eigthy two patients admitted to the coronary care unit with the diagnosis of AMI were included in this study. Serum Ig E, C-reactive protein (CRP), leukocyte count, and serum fibrinogen levels were obtained on admission and peak CK-MB and peak troponin-I levels were obtained. Patients whose serum Ig E levels on admission was below 200 IU/mL were classified as group 1 (n=62) and patients whose serum Ig E levels on admission was 200 IU/mL or above were classified as group II (n=20). Before discharge, standard echocardiographic assessment of the patients were performed and Reardon's coronary artery disease severity scores were determined by performing quantitative coronary angiographic evaluation of 58 patients from both groups. During the in-hospital period, patients were evaluated in terms of congestive heart failure, malign arrhytmias, post myocardial infarction (MI) angina, emergency revascularisation, death and development of total major adverse cardiovascular events (MACE). Results: CRP, peak CK-MB, peak troponin-I, leukocyte and fibrinogen levels of the patients in group 1 were higher significantly compared with those in group II (p<0.001, p<0.01, p<0.05, p<0.01, p<0.05, respectively). Measurements of left ventricular ejection fraction were higher in group II than in group 1 (p<0.05). During the in-hospital period, incidence of malign ventricular arrhytmias, post MI angina and MACE were significiantly lower in group II (p<0.05, p<0.05, p<0.05, respectively). Conclusion: Elevation of serum Ig E levels in patients with AMI may have positive effects on the size of necrosis and on the in-hospital course of infarction. Elevation of IgE levels can be used as a favourable prognostic marker in AMI.

Özet

Amaç: Ateroskleroz gelişimi ve akut miyokard infarktüsü (AMİ) fizyo-patolojisinde immün mekanizmaların önemli rol oynadığı bilinmektedir. Serum immünoglobulin E'nin (IgE) mast hücre aracılı mekanizmalarla AMİ seyri üzerine etkileri olabileceği düşünülmektedir. Bu çalışmada serum IgE düzeylerinin AMİ'ın hastane içi klinik seyri, infarktın genişliği, aterosklerotik damar tutulumu üzerine etkileri araştırıldı. Gereç ve Yöntem: Çalışmaya AMİ tanısıyla koroner yoğun bakım ünitesine yatırılan 82 hasta alındı. Hastalardan hastaneye kabulde serum IgE, C-reaktif protein (CRP), fibrinojen seviyesi ve lökosit sayısı için venöz kan alındı. Yine hastaneye kabulden itibaren 6 saatlik aralıklarla kan alınıp pik kreatin kinaz-MB (CK-MB) ve troponin-I değerleri çalışıldı. Başvuru sırasındaki serum IgE seviyeleri 200 IU/mL'nin altında olanlar grup 1 (n=62) ve üzerinde olanlar grup 2 (n=20) olarak ikiye ayrıldı. Hastaların taburcu edilmeden önce standart ekokardiyografileri yapıldı ve her iki gruptan toplam 58 hastanın koroner anjiyografisi yapılarak koroner arter hastalığı (KAH) yaygınlık Reardon şiddet skoru belirlendi. Yine hastalar hastane içi dönemde konjestif kalp yetmezliği (KKY), malign aritmiler, post miyokard infarktüs (Mİ) angina, acil revaskülarizasyon, ölüm ve toplam major kardiyovasküler istenmeyen olay (MACE) gelişimi açısından takip edildi. Bulgular: Grup 1'de CRP, pik CK-MB, pik troponin-I, lökosit, fibrinojen düzeyleri grup 2'ye göre anlamlı yüksekti (sırasıyla p<0.001, p<0.01, p<0.05, p<0.01, p<0.05). Sol ventrikül ejeksiyon fraksiyonu grup 2'de daha yüksekti (p<0.05). Hastane içi dönemde gelişen malign ventriküler aritmiler, post Mİ anjina, MACE grup 2'de belirgin olarak daha düşüktü (sırasıyla p<0.05, p<0.05, p<0.05) Sonuç: Serum IgE düzeyi yüksekliğinin AMİ'da nekrotik alan genişliği ve infarktüsün hastane içi dönem seyri üzerine olumlu etkileri mevcuttur. IgE yüksekliği AMİ'de olumlu prognostik marker olarak kullanılabilir.
