Résumé
This study was conducted to detect atherosclerotic plaques with somatostatin receptor scintigraphy (SRS) using Tc-99m-octreotide that binds to somatostatin receptor-2. Of the 783 patients referred for myocardial perfusion imaging (MPI), 52 underwent additional chest single-photon emission computed tomography (SPECT) with Tc-99m-octreotide and participated in this study. In addition, 43 patients who underwent Tc-99m-octreotide scan for neuroendocrine tumor (NET) also received cardiac SPECT. Angiography was performed within 1 month after SRS for 19 patients who showed intensive uptake in SRS and had cardiac risk factors. Of 52 patients who underwent MPI and SRS, 15 showed intensive cardiac uptake in SRS. Moreover, of 43 patients who were referred for NET, 4 patients had marked cardiac uptake in SRS in the heart. Nineteen patients including 12 women and 7 men aged 28 to 84 (58±8.04) years underwent coronary angiography. SRS and angiography in the left anterior descending territory were concordant in 15/19 (79%) patients, whereas only 7/15 (46%) cases had concordant MPI and angiography results. In the right coronary artery territory, SRS and angiography were concordant in 16/19 (84%) cases, while MPI and angiography were concordant in 11/15 (73%) cases. In the left circumflex artery territory, SRS and angiography were concordant in 15/19 (79%) cases, whereas MPI and angiography were concordant in 6/15 (40%) cases. In the remaining 76 patients who did not undergo coronary angiography based on cardiovascular profile and SRS, no cardiac events occurred in a follow-up of 2-11 months (7.52±2.71). Tc-99m-octreotide uptake was more concordant with coronary plaques relative to MPI findings, suggesting a potential role for Tc-99m-octreotide in the evaluation of atherosclerosis. Bu çalışma, somatostatin reseptör-2’ye bağlanan Tc-99m-oktreotid kullanılarak somatostatin reseptör sintigrafisi (SRS) ile aterosklerotik plakların saptanması amacıyla yapılmıştır. Miyokardiyal perfüzyon görüntülemesi (MPI) için sevk edilen 783 hastadan 52’sine ek olarak Tc-99m-oktreotid ile göğüs tek foton emisyonlu bilgisayarlı tomografisi (SPECT) uygulandı ve bu hastalar çalışmaya katıldı. Ayrıca, nöroendokrin tümör (NET) için Tc-99m-oktreotid taraması yapılan 43 hastaya da kardiyak SPECT uygulandı. SRS’de yoğun tutulum gösteren ve kardiyak risk faktörü taşıyan 19 hastaya SRS’den sonraki 1 ay içinde anjiyografi yapıldı. MPI ve SRS uygulanan 52 hastanın 15’inde SRS’de yoğun kardiyak tutulum görüldü. Ayrıca NET için yönlendirilen 43 hastanın 4’ünde kalpte SRS’de belirgin kardiyak tutulum saptandı. Yaşları 28 ile 84 (58±8,04) arasında değişen 12’si kadın, 7’si erkek olmak üzere 19 hastaya koroner anjiyografi yapıldı. SRS ve sol ön inen arter bölgesinde anjiyografi 15/19 (%79) hastada uyumlu iken, sadece 7/15 (%46) hastada uyumlu MPI ve anjiyografi sonuçları vardı. Sağ koroner arter bölgesinde 16/19 (%84) hastada SRS ve anjiyografi, 11/15 (%73) hastada MPI ve anjiyografi uyumluydu. Sol sirkumfleks arter bölgesinde 15/19 (%79) hastada SRS ve anjiyografi, 6/15 (%40) hastada MPI ve anjiyografi uyumluydu. Kardiyovasküler profil ve SRS’ye göre koroner anjiyografi yapılmayan geri kalan 76 hastada 2-11 aylık takipte (7,52±2,71) kardiyak olay gelişmedi. Miyokardiyal perfüzyon görüntülemesi bulgularına göre Tc-99m-oktreotid alımının koroner plaklarla daha uyumlu olması, aterosklerozun değerlendirilmesinde Tc-99m-oktreotidin potansiyel bir rolü olduğunu düşündürmektedir.
