Abstract

Aim: Catheter ablation of atrial fibrillation (AF) is a favourable therapeutic option for the treatment of patients, who are symptomatic despite antiarrhythmic medication. However, this procedure may lead to thromboembolic complications, especially stroke. We aimed to measure serum neuron-specific enolase (NSE) levels, which is known as biomarker of acute neuronal injury, during and after the ablation. Materials and Methods: Forty three patients with paroxysmal AF underwent pulmonary vein isolation performed by radiofrequency ablation. A neurological examination was performed pre- and postprocedural period. Serum NSE levels were determined before and at the end of the procedure, at 2, 24 and 48 hours after the procedure. Results: None of the patients developed new neurological deficits. But NSE levels increased after ablation above the upper reference limit of 17 ng/ml in 14 patients; and also 50% increase was observed compared to baseline in 33 patients. No clinical parameters such as age, hypertension, previous history of stroke, diabetes mellitus, atherosclerotic heart disease, CHA2DS2 VASc score FRPSRVLWH ULVN VFRUH SRLQW HDFK FRPSULVLQJ FRQJHVWLYH KHDUW IDLOXUH KSHUWHQVLRQ DJHHDUV SRLQWV GLDEHWHV VWURNH SRLQWV DJHHDUV YDVFXODU GLVHDVH DQG IHPDOH JHQGHU and no procedural parameters such as activated clotting time value, total procedure time, electrical cardioversion were associated with an increased level of NSE. But, patients with increased NSE level above the upper reference limit had larger left atrium and patients with 50% increase in NSE level had lower systolic blood pressure during the procedure. Conclusion: Serum NSE level increased in most of the patients undergoing catheter ablation for AF, also in one third of the patients it exceeded the upper reference limit. Despite increase in NSE is a marker of neuronal injury, clinical importance of this finding should be evaluated in a longitudinal study”

Özet

Amaç: Atriyal fibrilasyon (AF) kateter ablasyonu, antiaritmik tedaviye ra?men semptomatik olan hastalar için uygun bir tedavi seçene?idir. Ancak bu iLlem, baLta inme olmak üzere tromboembolik komplikasyonlara yol açabilmektedir. Biz, ablasyon iLlemi sÖrasÖnda ve sonrasÖnda, akut nöronal hasarÖn biyomarkerÖ olarak bilinen serum nöron spesifik enolaz (NSE) düzeylerindeki de?iLimi ölçmeyi amaçladÖk. Gereç ve Yöntem: Paroksismal AF'si olan 43 hastaya radyofrekans ablasyon yöntemi ile pulmoner ven izolasyonu yapÖldÖ. gLlem öncesi ve sonrasÖnda karLÖlaLtÖrmalÖ olarak nörolojik muayeneleri yapÖlan hastalarÖn serum NSE düzeyleri; iLlemden hemen önce, iLlemin sonunda, iLlem bittikten 2 saat, 24 saat ve 48 saat sonrasÖnda ölçülerek de?erlendirildi. Bulgular: HastalarÖn hiçbirinde yeni geliLen nörolojik defisit izlenmedi. Ama NSE seviyeleri 14 hastada üst referans limit olan 17 ng/ml'nin üzerine çÖktÖ ve 33 hastada bazal seviyesine göre %50 artÖL gösterdi. YaL, hipertansiyon, geçirilmiL inme, diyabet, aterosklerotik kalp hastalÖ?Ö varlÖ?Ö, CHA2DS2 VASc skoru [birleLik risk skoru [her biri 1 puan]: konjestif kalp yetmezli?i, hipertansiyon, 75 yaL ve üstü (2 puan), diyabet, inme (2 puan), 65 yaL ve üstü, vasküler hastalÖk, kadÖn cinsiyet] gibi klinik parametreler ve aktive pÖhtÖlaLma zamanÖ, toplam iLlem süresi, elektriksel kardiyoversiyon gibi iLlem iliLkili parametreler NSE seviyesinde artÖLla iliLkili bulunmadÖ. Ama, NSE seviyesi üst referans limitin üstüne yükselen hastalarÖn sol atriyum çaplarÖ daha geniLti ve NSE seviyesinde %50 artÖL izlenen hastalarÖn iLlem sÖrasÖndaki sistolik kan basÖncÖ de?erleri daha düLüktü. Sonuç: Serum NSE seviyeleri AF ablasyonu yapÖlan hastalarÖn büyük kÖsmÖnda artÖL göstermiL ve üçte birinde normalin üst sÖnÖrÖnÖ aLmÖLtÖr. Serum NSE düzeylerindeki artÖL nöronal hasarÖn bir belirteci olarak kabul edilse de AF ablasyonu yapÖlan hastalarda izlenen bu artÖLÖn serebral embolilerle iliLkisini ortaya koymak için daha ileri çalÖLmalara gerek vardÖr
