Abstract

Objective: The aim of present study was to assess the clinical utility and diagnostic accuracy of diastolic dysfunction criteria that were recommended in current American Society of Echocardiography and European Association of Echocardiography recommendations for prediction of increased LVEDP (>16 mmHg) in patients with coronary artery disease and normal EF. Methods: Forty-five consecutive patients (mean age=61.5±10.3 years) referred for cardiac catheterization were enrolled in this prospective study. All patients underwent transthoracic echocardiography and tissue Doppler imaging within 24 hours before cardiac catheterization. Patients were divided into 2 groups according to left ventricular end diastolic pressure (LVEDP) (LVEDP>16 mmHg, n=23; LVEDP≤16 mmHg, n=22). Receiver operating characteristics curve analyses were performed and sensitivity, specificity, positive predictive value and negative predictive value were calculated for indices to detect high LVEDP. Results: Among the indices, left atrial volume index (LAVI) ≥34 ml/m2 (sensitivity=60.0% and specificity=90.0%) and ratio of transmitral to septal annular velocities during early filling (septal E/e’ ratio) ≥15 (sensitivity=30.4% and specificity=95.5%) had more reasonable sensitivity and specificity. Receiver operating characteristics curve analysis revealed that best predictors of high LVEDP were septal E/e’ [area under curve (AUC)=0.694, standard error (SE)=0.66, p=0.01] and LAVI (AUC=0.669, SE=0.63, p=0.045]. There were statistically significant correlations between LVEDP and septal E/e’ (r=0.541, p=0.001) and LAVI (r=0.461, p=0.002). A proposed algorithm consisting LAVI ≥34 ml/m2 and septal E/e’ >8 could determine diastolic dysfunction with a 95.6% sensitivity and 54.5% specificity. Conclusion: Septal E/e’ (≥15) and LAVI (≥ 34 ml/m2) were the better predictors of the increased LVEDP than the other echocardiographic parameters. There were statistically significant moderate positive correlations of LVEDP with septal E/e’ and LAVI. Combination of LAVI and septal E/e’ is useful to detect diastolic dysfunction.

Özet

Amaç: Bu çalışmada ejeksiyon fraksiyonu normal olan koroner arter hastalarında sol ventrikül diyastol sonu basıncındaki artışı ön görmede Amerikan Ekokardiyografi Cemiyeti ve Avrupa Ekokardiyografi Birliği tarafından önerilen güncel diyastolik işlev bozukluğu göstergelerinin tanısal değeri ve klinik yararının araştırılması amaçlandı. Yöntemler: Bu ileriye dönük çalışmaya kalp kateterizasyonu için yönlendirilen toplam 42 hasta (ortalama yaş=61.5±10.3 yıl) alındı. Tüm hastalara kalp kateterizasyonu yapılmadan önceki 24 saat içinde transtorasik ekokardiyografi ve doku Doppler görüntüleme yapıldı. Hastalar sol ventrikül diyastol sonu basıncına (SoVDSB) göre 2 gruba ayrıldı (SoVDSB>16 mmHg, n=23; SoVDSB≤16 mmHg, n=22). Göstergeler için işlem karakteristik eğrisi analizi yapıldı ve yüksek LVEDP’yi saptamada duyarlılık, özgüllük, pozitif ve negatif ön gördürücü değerleri hesaplandı. Bulgular: Göstergeler arasında, sol atriyal hacim indeksi (SAHİ≥ 34 ml/m2, duyarlılık=%60.0 ve özgüllük=%90) ve septal E/e’ (≥15, duyarlılık=% 30.4 ve özgüllük=%95.5) en makul duyarlılık ve özgüllüğe sahipti. İşlem karakteristik eğrisi analizinde yüksek SoVDSB’yi öngörmede en iyi göstergelerin septal E/e’ [eğri altındaki alan (EAA)=0.694, standart hata (SH)=0.66, p=0.01] ve SAHİ (EAA=0.669, SH=0.63, p=0.045) olduğu bulundu. Septal E/e’ (r=0.541, p=0.001) ve SAHİ (r=0.461, p=0.002) ile SoVDSB arasında istatistiksel anlamlı korelasyon saptandı. Bu göstergelerin kullanıldığı bir algoritmada SAHİ ≥34 ml/m2 ve septal E/e’ >8 oluşunun diyastolik işlev bozukluğunu %95.6 duyarlılık ve %54.5 özgüllük ile belirlediği bulundu. Sonuç: Septal E/e’ (≥15) ve SAHİ (≥ 34 ml/m2) diğer ekokardiyografik parametrelere göre artmış SoVDSB’nin daha iyi öngördürücüleridir. Septal E/e’ ve SAHİ ile SoVDSB arasında istatistiksel anlamlı orta derece korelasyon bulunmaktadır. SAHİ ve septal E/e’nin kombinasyonu diyastolik işlev bozukluğunu saptamada yararlıdır.
