Abstract

Objectives : Uric acid (UA) is the e nd-product of purine metabolism and is a well-known risk factor for gout disease. In addition to that, elevated serum UA levels have been associated with many disorders including insulin resistance, obesity, hypertension, renal dysfunction and hypothyroidi sm. On the other hand, whether uric acid has any causal relationship with cardiovascular morbidity is a debated issue. Materials and Methods : This retrospective study included totally 326 patients who were inpatients at the Cardiology Ward or Coronary Int ensive Care Unit of Ankara Numune Training and Research Hospital between March 2016 and February 2017. Data regarding serum UA and N-terminal pro B-type Natriuretic P eptide ( NT-proBNP ) levels and left ventricular ejection fraction %) LVEF) were retrieved f rom the hospital information system. Patients were categorized into four groups based on their UA levels (Group 1 UA: 2.7-4.9 mg/dL, Group 2 UA: 5-6 mg/dL, Group 3 UA: 6.1-7.4 mg/dL, Group 4 UA: 7.5-15.6 mg/dL). Other parameters were compared between the g roups using ANOVA test. Additionally, the effects of gender, age and eGFR w ere also examined when evaluating the changes in left ventricular function according to UA levels. Correlation between the variables was analyzed with Pearson’s correlation test. Re sults: Group 4 was significantly different than the rest of the groups in terms of age, NT-proBNP and eGFR (p<0.001). In addition, group 4 showed significant difference from Group 1 and Group 3 regarding %LVEF (p=0.006 and p=0.002, respectively). However, the differences between the groups regarding %LVEF was not influenced by age or eGFR. Regardless of the groups, serum UA levels showed statistically significant but weak positive correlation with NT-proBNP (r=0.310, p<0.001), and low level of negative corr elation with % LVEF, which was statistically significant (r=-0.173, p=0.002). Conclusion : Based on our findings, we concluded that serum UA level has prognostic sign ificance in cardiac dysfunction and can be used in the follow-up of such patients.

Özet

Amaç : Ürik asit, pürin metabolizmasının son ürünü ve gut için iyi bilinen bir risk faktörüdür. Bununla birlikte, yüksek serum ürik asit düzeyleri insülin rezistansı, obezite , hipertansiyon, renal disfonksiyon, hipotiroidi gibi birçok hastalıkla ilişkili bulunmuştur. Öte yandan, ürik asidin kardiyovasküler morbiditede nedensel bir rol oynayıp oynamadığı tartışılmaktadır. Çalışmamızda serum ürik asit (ÜA) ve kalp yetmezliği prognostik belirteci olan N terminal pro B - tipi Natriüretik P eptit ( NT-proBNP ) düzeyleri ile sol ventrikül f onksiyon bozukluğu arasında ilişki olup olmadığını araştırmayı amaçladık. Materyal ve Metot : Çalışma retrospektif olarak planlandı. Mart 2016 ile Şubat 2017 tarihleri arasında Ankara Numune Eğitim ve Araştırma Hastanesi Kardiyoloji Servisi ve Koroner Yoğun Bakımda yatan 326 hasta çalışmaya dahil edildi. Bu hastaların serum ÜA, NT-proBNP düzeyleri ile ejeksiyon fraksiyonu (EF) bulguları hastane enformasyon sisteminden alındı. Hastalar serum ÜA düzeylerine göre 4 gruba ayrıldı (1. grup ÜA; 2 , 7-4 , 9 mg/dL, 2. g rup ÜA; 5-6 mg/dL, 3. grup ÜA; 6 , 1-7 , 4 mg/dL, 4. grup ÜA; 7 , 5-15 , 6 mg/dL). Gruplar arasında parametreler ANOVA testi kullanılarak karşılaştırıldı. Ayrıca, sol ventrikül disfonksiyon bulgularında ürat düzeylerine göre değişimler incelenirken, cinsiyet, yaş ve eGFR ‘nin bu parametreler üzerindeki etkileri değerlendirildi. Değişkenler arasında ilişki için Pearson korelasyon testi kullanıldı. Bulgular: 4. grup; yaş, NT-proBNP, eGFR diğer gruplardan anlamlı düzeyde farklıydı (p<0.001). EF, 4. grup ile 1. ve 3. g ruplar arasında anlamlı farklı bulundu (sırası ile p=0 , 006 and p=0 , 002). Ancak EF’nun gruplar arasındaki farklılıkları üzerinde yaş ve eGFR etkisinin olmadığı görüldü. Gruplardan bağımsız olarak serum ÜA düzeyi ile NT-proBNP arasında istatistiksel olarak a nlamlı ancak zayıf pozitif korelasyon (r=0 , 310, p<0 , 001), % LVEF arasında ise düşük düzeyde ancak anlamlı negatif korelasyon (r=-0 , 173, p=0 , 002) tespit edildi. Sonuç: Çalışmamızdaki bulgulara göre serum ÜA düzeyinin kardiyak disfonksiyonda prognostik önem e sahip olduğu ve hastaların takibinde kullanılabileceği kanısına varılmıştır.
