Abstract

Objective: The aim of the study was to compare diagnostic accuracy of tissue Doppler imaging (TDI) and conventional Doppler echocardiography in diagnosis of left ventricular diastolic dysfunction in patients with cardiac syndrome X. Methods: Our study was designed as cross-sectional study. In our study, we compared 35 patients with cardiac syndrome X (19 female, mean age 47.2±7.3 years) with 33 healthy persons as control group (18 female, mean age 49.5±7.1 years) with no coronary artery disease and having no ischemic complaints or findings at exercise test. Left ventricular systolic function was found by considering mean values of modified Simpson method for left ventricular ejection fraction and TDI assessment of systolic wave peak velocity. The diastolic function of left ventricle was assessed with conventional echocardiography and TDI. Unpaired t test for independent samples or Mann-Whitney U test were used for comparison of continuous variables, Chi square test - for comparison of categorical variables. To define the capability of predicting diastolic dysfunction for conventional Doppler echocardiography and tissue Doppler imaging ROC curve analysis was applied.Results: Left ventricular ejection fraction and systolic wave peak velocity were similar for both groups. Conventional Doppler echocardiographic measurements for left ventricular diastolic functions delineated the more frequent presence of diastolic dysfunction in cardiac syndrome X group As compared with controls (48% vs 18%; p

Özet

Amaç: Çalışmanın amacı konvansiyonel ve doku Doppler ekokardiyografinin kardiyak sendrom X hastalarında diyastolik disfonksiyonu tanısında diyagnostik değerini karşılaştırmaktır. Yöntemler: Çalışmamız enine-kesitli olarak dizayn edildi. Çalışmamız kardiyak sendrom X’li 35 hasta (19 kadın; ortalama yaş 47.2±7.3 yıl) ve kontrol grubu olarak efor testinde iskemi bulgusu olmayan normal koroner arterlere sahip 33 sağlıklı birey (18 kadın, ortalama yaş 49.5±7.1 yıl) alınarak gerçekleştirildi. Sol ventrikül sistolik fonksiyonları modifiye Simpson yöntemi ile elde edilen ejeksiyon fraksiyonlarının ortalaması ve doku Doppler ekokardiyografide sistolik akım tepe hızları ölçülerek hesaplandı. Sol ventrikül diyastolik fonksiyonu ise konvansiyonel ve doku Doppler ekokardiyografi ile değerlendirildi. Sürekli değişkenlerin karşılaştırılmasında bağımsız örneklem eşleştirilmemiş t testi veya Mann-Whitney U, kategorik değişkenlerin karşılaştırılmasında Ki-kare testi kullanıldı. Konvansiyonel ve doku Doppler ekokardiyografinin kardiyak sendrom X hastalarında diyastolik disfonksiyonu öngörme yetisi için ROC eğrisi kullanıldı. Bulgular: Sol ventrikül ejeksiyon fraksiyonları ve sistolik akım tepe akım hızları her iki grupta benzer özellik gösteriyordu. Konvansiyonel ekokardiyografik ölçümler diyastolik disfonksiyonlu hasta sayısının kardiyak sendrom X’li grubunda daha fazla olduğunu göstermekte idi (%48’e karşı %18, p
