Abstract

Aim: Ventricular function is normal in almost half of the congestive heart failure cases and this condition can be explained by diastolic dysfunction. The left ventricular diastolic filling abnormalities are more sensitive comparing to systolic functional parameters in terms of determining coronary artery disease (CAD). The aim of this study is to investigate the changes of left ventricular diastolic functional parameters in 1, 2, 3 vessel and left main CAD patients before and after sublingual nitrate in terms of demonstrating the severity of the CAD noninvasively. Material and Method: The cardiac catheterization proved 1, 2, 3 vessel and left main coronary artery lesion patients diastolic Doppler measurements were performed before and 5 minutes after sublingual isosorbide dinitrate (5 mg). Diastolic Doppler parameters, isovolumic relaxation time (IVRT), E and A wave peak flows (E peak, A peak), E/A ratio, E wave deceleration time (DecE) were calculated. Results: Twenty six cases (40 %) were single vessel (age 52.4±2.2), 23 were (36 %) double vessel (age 51.7±4.8), 13 were (20 %) triple vessel disease (age 50.1±2 ) and 2 of them were (0.3 %) found as left main CAD (age 59.4±3.9). E peak measurements were found statistically significant regarding with single vessel, triple vessel and left main coronary lesion before and after sublingual nitrate (p<0.05). Diastolic functional measurements (E peak, E/A ratio, E dec) were found statistically significant regarding with double, triple vessel and left main coronary lesion before and after sublingual nitrate (p>0.05). Conclusion: We concluded that the CAD severity can also be determined noninvasively from the transmitral flow by utilizing sublingual nitrate test in terms of left ventricle diastolic functional parameters, which are E peak, E/A ratio, E dec.

Özet

Amaç: Kalp yetmezliği vakalarının yaklaşık yarısında sol ventrikül sistolik işlevi normaldir ve bu durum sol ventrikül diyastolik fonksiyon bozukluğu ile açıklanmaktadır. Sol ventrikül diyastolik doluş anormallikleri, koroner arter hastalığı ciddiyeti (KAH) incelenmesinde sistolik fonksiyon parametrelerinden daha özgündür. Bu çalışmanın amacı 1, 2, 3 ve sol ana koroner arter lezyonu olanlarda sol ventrikül diyastolik fonksiyon parametrelerinin sublingual nitrat uygulanımı sonrası değişimini incelemek ve buna bağlı olarak KAH ciddiyetini noninvaziv olarak ortaya koyabilmektir. Gereç ve Yöntem: Kateterizasyon ile 1, 2, 3 ve sol ana koroner arter lezyonu olduğu saptanan hastalara diyastolik Doppler ölçümleri, dilaltı Isosorbid dinitrat (5 mg) verildikten 5 dk sonrasında gerçekleştirildi. Diyastolik Doppler parametreleri olarak izovolumik relaksasyon zamanı (IVRZ), E ve A dalga pik akımları (E pik, A pik), E/A oranı, E dalga deselerasyon (iniş) zamanı (DecE) hesaplandı. Bulgular: Vakaların 26 tanesinde (% 40) tek damar (yaş ortalaması 52.4±2.2 yıl), 23 tanesinde (% 36) iki damar (yaş ortalaması 51.7±4.8 yıl), 13 tanesinde (%20) üç damar (yaş ortalaması 50.1±2 yıl) ve 2 tanesinde (% 0.3) ise sol ana KAH (yaş ortalaması 59.4±3.9 yıl) tespit edildi. Tek damar, üç damar ve sol ana koroner lezyonu olan vakaların nitrat öncesi ve sonrası E pik ölçümleri istatistiksel açıdan anlamlı olarak saptandı (p<0.05). Nitrat öncesi ve sonrası diyastolik fonksiyon ölçümleri (E pik, E/A oranı, E dec) istatistiksel incelemesi iki, üç damar ve sol ana koroner damar lezyonu açısından anlamlı olarak saptandı (p<0.05). Sonuç: Sublingual nitrat verilerek transmitral Doppler kayıtlarından faydalanarak SV diyastolik fonksiyon parametrelerinden özellikle E pik, E/A oranı ve E dec zamanı değerlerinin incelenmesi sonucu koroner arter hastalığı ciddiyeti hakkında noninvaziv olarak da karar verilebileceği sonucuna varılmıştır.
