Abstract

Objectives: Post-stress left ventricular ejection fraction (LVEF) and LV volumes have incremental value in predicting cardiac death (CD) in patients with coronary artery disease. In this study, we aimed to investigate the effect of imaging time after exercise on post-stress LVEF, end-diastolic volume (EDV) and end-systolic volume (ESV) calculated by cardiac quantification software program called Quantitative Gated SPECT (QGS-Cedars-Sinai).Materials and methods: This study was consisted of 36 patient referred to Nuclear Medicine Department from Cardiology Clinics because of chest pain in ‘Elazig Research and Training Hospital’ in 2008-2009. In all patients, ECG Gated (8-bin frame mode) myocardial perfusion SPECT scintigraphy was performed 20 and 40 min later following 99mTc-Mibi injection during exercise. By means of the cardiac quantification software program called Quantitative Gated SPECT (QGS-Cedars-Sinai); LVEF, EDV and ESV were calculated. LVEF, EDV and ESV values obtained from initial and second acquisition were compared statistically.Results: There was no statistically significant difference between post-stress LVEF, EDV and ESV measures of initial and second acquisition (p>0.05). Conclusion: Left ventricular functional parameters after exercise are important for assess prognosis in patients with CAD. Post-stress LVEF, EDV and ESV measured on gated myocardial perfusion SPECT images within 20-40 min after completion of exercise give reproducible information.

Özet

Amaç: Efor sonrası sol ventrikül ejeksiyon fraksiyonu (LVEF) ve sol ventrikül volüm değerlerinin koroner arter hastalığı bulunan hastalardaki kardiyak ölüm tahmininde katkısı vardır. Bu çalışmada, efor sonrası görüntüleme zamanının Quantitative Gated SPECT (QGS-Cedars-Sinai) programı ile hesaplanan efor sonrası LVEF, end-diastolik volüm (EDV) ve end-sistolik volüm (ESV) üzerine etkisini araştırmayı amaçladık. Hastalar ve yöntem: Bu çalışma 2008 ve 2009 yıllarında Elazığ Eğitim ve Araştırma Hastanesi Nükleer Tıp Birimine göğüs ağrısı nedeniyle Kardiyoloji Kliniğinden gönderilen 36 hasta üzerinde yapıldı. Tüm hastalara efor esnasında yapılan 99mTc-Mibi enjeksiyonunu takiben 20. ve 40. dakikalarda EKG-gated (8-bin frame modunda) miyokard perfüzyon SPECT sintigrafisi uygulandı. Kardiyak kantifikasyon yazılımı olan QGS programı kullanılarak LVEF, EDV ve ESV hesaplandı. İlk ve ikinci görüntülemelerden elde edilen LVEF, EDV ve ESV değerleri istatistiksel olarak birbirleri ile karşılaştırıldı.Bulgular: İlk ve ikinci görüntülemelerden elde edilen LVEF, EDV ve ESV değerleri arasında istatistiksel olarak anlamlı farklılık bulunmadı (p>0.05).Sonuç: Efor sonrası sol ventrikül fonksiyon parametreleri koroner arter hastalığı bulunan hastalardaki prognoz değerlendirmesinde önemlidir. Efor bitiminden 20-40 dakika sonra yapılan miyokard perfüzyon SPECT sintigrafisi efor sonrası LVEF, EDV ve ESV değerleri açısından tekrarlanabilir değerler vermektedir.
