Abstract

Objectives: We investigated correlations between regional rest myocardial perfusion and regional systolic and diastolic myocardial velocities assessed by 99mTc MIBI gated single-photon emission computed tomography (G-SPECT) and tissue Doppler echocardiography, respectively, in dilated cardiomyopathy (DCM). Study design: The study included 32 patients (27 men, 5 women; mean age 63±12 years) with DCM, with NYHA functional capacity II-IV. Twenty-five patients had ischemic, seven patients had nonischemic DCM. G-SPECT and tissue Doppler imaging studies were performed using short axis views of the basal, mid, and apical levels of the left ventricle, which was divided into 16 segments. For each segment, regional 99mTc MIBI uptake and peak systolic (Sm), and early (Em) and late (Am) diastolic velocities were determined. Results: The mean Sm value (p=0.007) was significantly higher and the mean 99mTc MIBI uptake (p

Özet

Amaç: Dilate kardiyomiyopatili (DKM) hastalarda 99mTc MIBI gated tek-foton emisyon bilgisayarlı tomografi (G-SPECT) ile istirahatte ölçülen bölgesel miyokard perfüzyonu ile doku Doppler ekokardiyografi ile ölçülen sol ventrikül bölgesel sistolik ve diyastolik akım hızları arasındaki bağıntı araştırıldı. Çalışma planı: Çalışmaya fonksiyonel kapasitesi NYHA II-IV olan DKMli 32 hasta (27 erkek, 5 kadın; ort. yaş 63±12) alındı. Yirmi beş hastada iskemik, yedi hastada iskemik olmayan DKM vardı. G-SPECT ve doku Doppler ölçümleri, sol ventrikül kısa eksende 16 segmente bölünerek bazal, mid ve apikal seviyelerde yapıldı. Her miyokard segmentinde bölgesel 99mTc MIBI tutulumu ve zirve sistolik akım hızı (Sm), erken (Em) ve geç (Am) diyastolik akım hızları değerlendirildi. Bulgular: Ortalama Sm değeri, iskemik grupta daha yüksek (p=0.007), ortalama 99mTc MIBI tutulum yüzdesi daha düşüktü (p
