Abstract

Aim: Findings from basic medicine investigations show that atherosclerosis is an inflammatory disease. C-reactive protein (CRP) is an acute phase reactant and because of this, it is a marker for systemic inflammation. It was reported that high CRP levels might lead to poor clinical results at ischemic events. In this study, we investigated whether the inflammatory activity detected by CRP levels was different or not between troponin positive and troponin negative non-ST elevation acute coronary syndrome (NSTE-ACS) patients. Material and Methods: This study was performed at 202 NSTE-ACS patients admitted to our clinic with chest pain. For troponin measurement, 50 µL serum obtained from venous blood samples taken at 12 and 24 hour after admission was used. Patients with peak cardiac troponin-I (cTn-I) levels equal and greater than 1.0 ng/ml were grouped as cTn-I positive, whereas those with peak cTn-I levels less than 1.0 ng/ml were grouped as cTn-I negative. For CRP measurement, venous blood serum taken at admission was used. Normal values for CRP were accepted as 0-7 mg/L. Results: Seventy three patients (37%) were troponin positive and 129 patients (63%) were troponin negative. There was a positive correlation between troponin and CRP levels among troponin positive patients (r=0.381, p<0.05). It was detected by logistic regression analysis that CRP levels were an independent predictor of troponin positivity at NSTE-ACS patients (=0.034, OR=1.035 (95%CI 1.010<OR Conclusion: At NSTE-ACS patients, increased CRP levels are correlated with myocardial injury.

Özet

Amaç: Temel tıp araştırmalarından sağlanan kanıtlar aterosklerozun inflamatuvar bir hastalık olduğunu göstermektedir. CRP bir akut faz reaktanıdır ve dolayısıyla da sistemik inflamasyon için bir belirleyicidir. Yüksek CRP seviyelerinin iskemik olaylarda kötü bir klinik sonucu öngörebileceği bildirilmektedir. Biz de bu çalışmada troponin pozitif ve negatif NSTE-AKS'li hastalarda CRP ile belirlenen inflamatuvar aktivitenin farklı olup olmadığını araştırdık. Gereç ve Yöntem: Bu çalışma, kliniğimize göğüs ağrısı yakınması ile başvuran NSTE-AKS'li 202 hastada yapıldı. Troponin ölçümleri için başvurudan 12 ve 24 saat sonra alınan venöz kan örneklerinden elde edilen 50µL serum kullanıldı. Pik kardiyak troponin-I (cTn-I) düzeyi 1.0 ng/ml ve üzerinde olan hastalar cTn-I pozitif, 1.0 ng/ml'nin altında olanlar ise cTn-I negatif kararsız angina olarak gruplandırıldı. CRP ölçümü için başvuru sırasında alınan venöz kan serumu kullanıldı. CRP için normal serum düzeyleri 0-7 mg/L kabul edildi. Bulgular: Analize katılan hastaların içinde 73 hasta (%37) troponin pozitif, 129 hasta (%63) troponin negatif olarak saptandı. Troponin pozitif olan hastaların; troponin düzeyleri ile CRP düzeyleri arasında pozitif yönde anlamlı bir ilişki vardı (r=0.381, p<0.05). Lojistik regresyon analiziyle NSTE-AKS hastalardaki CRP düzeylerinin, troponin pozitifliğinin bağımsız prediktörü olduğu saptandı ( =0.034, OR=1.035 (95%CI 1.010<OR<0.005). Sonuç: NSTE-AKS'li hastalarda artmış CRP düzeyleri miyokart hasarı ile ilişkilidir.
