Abstract (2. Language): 
Single photon emission computed tomography (SPECT) imaging with 99mTc sestamibi is used to assess the location or the extent of myocardial ischemia. Echocardiography has the ability to evaluate wall motion, measurement of left ventricular (LV) volumes and ejection fraction (EF). The goal of this study was to compare measurements of left ventricular geometry parameters in ischemic and non-ischemic patients along with SPECT and echocardiography. Consecutive 78 patients (mean age 47±14 years, 38 males, 40 females) with suspected coronary artery disease were enrolled. In all patients, SPECT and good-quality echocardiographic recordings were studied retrospectively. Patients were divided into two groups: ischemic (n=27) and non-ischemic (n=51) according to MPS. All patients examined according to the study protocol, which included registration of weight, height, sex and echocardiography data. Echocardiographic parameters were also compared with MPS. Only end diastolic left ventricular diameter (EDLVD) was significantly higher in the ischemic group than in the nonischemic group (5.1±0.6 vs 4.7±0.8; p<0.05). There was no significant difference in LVMI (109.8±45.2 vs 130.4±96.0, p>0.2); CO (4.6±2.4 vs 4.8±2.4, p>0.05); EF (59.9±11.0 vs 60.2±7.8, p>0.05); FS (23.1±14.2 vs 22.2±16.2, p>0.05); SWT (1.0±0.2 vs 1.0±0.3, p>0.05) and PWT (0.9±0.2 vs 1.0±0.3, p>0.05) parameters in echocardiography between patients with non-ischemic and ischemic, respectively. Echocardiographically, left ventricular diastolic diameters were significantly higher in patients with ischemic than in non-ischemic patients. Thus, these associated EDLVD differences have given important information about cascade of ischemic heart disease.

Abstract (Original Language): 
Amaç: 99mTc sestamibi ile miyokard perfüzyon sintigrafisi (MPS) miyokard iskemisini değerlendirmede kullanılmaktadır. Ekokardiyografi ise miyokard duvar hareketlerinin, ventrikül volümünün ve ejeksiyon fraksiyonun (EF) ölçümünde kullanılır. Çalışmamızın amacı; MPS ile iskemik ve normal değerlendirilen hasta grupları arasında ekokardiyografi ile elde edilen sol ventrikül verilerini karşılaştırmaktı. Hastalar: Şüpheli KAH olan, hem ekokardiyografi hem de MPS yapılmış 78 hastanın (ortalama yaş 47±14 yıl, 38 erkek ve 40 kadın) verileri retrospektif olarak değerlendirildi. MPS sonucuna göre hastalar normal (=51) ve iskemik (=27) olarak iki gruba ayrıldı. Hastaların tüm verileri (yaş, cinsiyet, kilo, boy, vücut kitle endeksi) çalışıldı. Ayrıca ekokardiyografi verileri de MPS sonucuna göre karşılaştırıldı. Sonuçlar: Hasta grupları arasında demografik veriler arasında anlamlı fark yoktu. Hasta grupları arasında ekokardiyografi verileri içinde sadece diastol sonu sol ventrikül çapı iskemik grupta (5.1±0.6) normal vakalara (4.7±0.8) göre anlamlı olarak yüksekti (p<0.05). Diğer ekokardiyografi verilerinde anlamlı farklılık yoktu (sırasıyla normal ve iskemik hastalar): (1) LVMI (109.8±45.2 ile 130.4±96.0, p>0.2); (2) CO (4.6±2.4 ile 4.8±2.4, p>0.05); (3) EF (59.9 ±11.0 ile 60.2±7.8, p>0.05); (4) FS (23.1±14.2 ile 22.2±16.2, p>0.05); (5) SWT (1.0±0.2 ile 1.0±0.3, p>0.05), (6) PWT (0.9±0.2 ile 1.0±0.3, p>0.05). Tartışma: Ekokardiyografi sonucuna göre sol ventrikül diastolik çap iskemik hastalarda normallere göre geniştir. Bu bulgu iskemik kalp hastalığının süreci hakkında önemli bulgu sağlamaktadır.
