Abstract

Objective: The aim of this study was to assess the myocardial energy expenditure (MEE) in patients with cardiac syndrome X (CSX) and to examine its association with exercise electrocardiogram (ECG) parameters. Methods: A total of 99 patients who underwent coronary angiography and who were diagnosed as having normal coronary arteries were included. The patients were divided into 2 groups based on symptoms and exercise ECG parameters: 56 CSX patients and 43 control patients with a negative stress test. MEE was calculated using transthoracic echocardiography- derived parameters: circumferential end-systolic stress, left ventricular ejection time, and stroke volume. Results: In patients with CSX, the MEE at rest was 28% higher in than the control group (89.2±36.3 vs. 69.8±17.2 cal/ minute). Correlation analysis revealed a moderately negative correlation between MEE and the Duke treadmill score (DTS) (β:-0.456; p

Özet

Amaç: Kardiyak sendrom X’li (KSX) hastalarda miyokardınenerji tüketimini (myocardial energy expenditure, MEE) değerlendirmeyive bu parametrenin egzersiz EKG parametreleriile ilişkisini incelenmeyi amaçladık.Yöntemler: Koroner anjiyografileri yapılan ve normal koronerarterler saptanan ardışık 99 hasta çalışmaya dahil edildi. Hastalarsemptom ve egzersiz EKG parametrelerine göre ikiyeayrıldı: KSX’li 56 hasta ve negatif egzersiz testi olan 43 kontrolhastası. MEE, transtorasik ekokardiyografi ile elde edilensirkümferensiyal sistol sonu stresi, atım hacmi ve sol ventrikülejeksiyon süresi parametreleri kullanılarak hesaplandı.Bulgular: Kardiyak sendrom X’li hastalarda istirahattakiMEE(dk) değeri kontrol grubuna göre %28 daha fazlaydı(89.2±36.3 ve 69.8±17.2). Korelasyon analizinde MEE(dk) ileDuke tredmil skoru (DTS) arasında orta düzeyde negatif korelasyonsaptandı (β:-0.456, p
