Abstract

AIM: To investigate the alterations of oxygen (O2) kinetics at submaximal constant exercise level before and after successful percutaneous transluminal coronary angioplasty (PTCA). MATERIAL AND METHODS: Twentysix patients (23 men and 3 women, mean age 52±9), who had single vessel disease and hospitalized for an elective PTCA were enrolled to the study. All patients underwent cardiopulmonary exercise test 24 hours before, and 48 hours after PTCA. They walked on a walking band with a 5 degree slope at a speed of 2,5km/hr for 6 minutes according to the modified Bruce protocol level II. O2 deficit values and the mean response times which were needed to obtain determined O2 consumption were estimated from the O2 consumption (VO2) curves. RESULTS: PTCA was failed in three patients. A decrease in O2 deficit was noticed in 20 of 23 patients after succesful PTCA. The mean pre-PTCA O2 deficit value was 660±211ml, and the mean post-PTCA O2 deficit value was 535±200ml. The difference between two values was found statistically significant (p=0.001). The pre-PTCA mean response time was 45±9sec, and the post-PTCA one was 40±11sec. This difference was also significant (p=0.004). CONCLUSION: The decreases in O2 deficit value and the mean response time, in the early period after a PTCA correlate with success of the procedure.

Özet

AMAÇ: Bu çalışmada, başarılı perkütan translüminal koroner anjiyoplastinin (PTKA) erken dönemde submaksimal sabit efor seviyesinde elde edilen oksijen (O2) kinetik değerleri üzerinde yarattığı etkiyi değerlendirmeyi amaçladık. GEREÇ VE YÖNTEM: Çalışmaya, elektif PTKA için yatırılan, tek damar lezyonu olan, yaşları 52±9, 23'ü erkek 3'ü kadın, toplam 26 olgu alındı. Kardiyopulmoner egzersiz testiyle tüm hastalar PTKA'dan önceki 24 saat ve PTKA'dan sonraki ilk 48 saat içinde modifiye Bruce protokolü 2. kademede (2,5 km/saat yürüyüş bandı hızı ve 5 derece eğim) 6 dakika yürütüldü. O2 tüketim (VO2) eğrilerinden, kararlı O2 tüketimine ulaşmak için gereken ortalama yanıt süreleri ve O2 defisit değerleri hesaplandı. BULGULAR: Üç olgumuzda PTKA girişimi başarısız oldu. Başarılı PTKA sonrası 23 olgunun 20'sinde O2 defisitte azalma dikkati çekti. İşlemden önce ölçülen ortalama O2 defisit değeri 660±211ml olup, başarılı PTCA sonrası bu değer 535±200ml'ye düştü, aradaki fark istatistiksel olarak anlamlı bulundu (p=0,001). Bu grupta ortalama yanıt süresi 45±9sn'den 40±11sn'ye azalma gösterdi (p=0,004). SONUÇ: Erken dönemde O2 defisit değerinde ve ortalama yanıt süresinde anlamlı azalma görülüyor olması PTKA sonrası işlem başarısı ile ilişkilidir.
