    Assessment of the relationship between coronary flow rates and myocardial perfusion abnormality in patients with nonobstructive coronary artery disease: an observational study in cardiac syndrome X and coronary slow flow
    (Lippincott Williams & Wilkins, 2019) Özde, Cem; Aktüre, Gülşah; Aytekin, Seda; Sayın, Ahmet Egemen; Ay, Esra Koç; Coşkun, Gökhan; Kayapınar, Osman
    Objectives In this study, we evaluated and compared the level of myocardial ischaemia caused by cardiac syndrome X (CSX) and coronary slow flow (CSF) with single photon emission computed tomography myocardial perfusion imaging (SPECT-MPI), and determined if changes in the level of myocardial ischaemia exist in CSF and CSX cases according to thrombolysis in myocardial infarction frame count (TFC). Materials and methods The study population consisted of 66 patients with CSF and 78 angiographically normal patients (36 of them with CSX and 42 of them healthy controls). The coronary flow rates of all patients were documented using TFC. Subsequently, all patients were evaluated with SPECT-MPI and categorized into the following groups according to their results: patients with CSF, patients with CSX, and patients with normal coronary arteries. Finally, we investigated whether a relationship existed between the SPECT-MPI and TFC results from these three groups. Results All ischaemia scores for MPI were significantly higher in the CSF group than in the CSX and control groups (P < 0.05). TFC was significantly associated with the severity of ischaemia in the CSF patients. There was a significant positive correlation between the summon difference score (SDS) and mean TFC value (P < 0.05) as well as between the SDS and each individual coronary TFC value in the CSF patients (P < 0.05). The number of vessels involved in CSF was positively correlated with the SDS. Conclusion CSF is associated with more severe myocardial ischaemia than CSX. The level of myocardial ischaemia on SPECT-MPI was correlated with the TFC and the number of affected coronary vessels in patients with CSF. These results suggest that CSF is a more serious clinical entity than CSX, and that the clinical severity of CSF appears to increase as the coronary flow rate decreases.

    Comparison of Changes in Anxiety and Depression Level Between Dabigatran and Warfarin Use in Patients With Atrial Fibrillation
    (Sage Publications Inc, 2017) Türker, Yasin; Ekinözü, İsmail; Aytekin, Seda; Türker, Yasemin; Başar, Cengiz; Baltacı, Davut; Kaya, Ertuğrul
    We hypothesized that patients taking warfarin require frequent hospital follow-up and they are at higher risk for complications, so the incidence of depression and anxiety is higher in patients with atrial fibrillation (AF) in the period of taking warfarin compared to the period of taking dabigatran. Fifty patients having AF without valvular diseases under treatment of warfarin in whom a transition to dabigatran was planned were consecutively enrolled in this study and followed up prospectively between July 2013 and July 2014. All patients completed Beck Depression Inventory and Hamilton Anxiety Scale (HAS) at the initiation of study and 6 months after initiation of study. Of the patients enrolled in the study, age, gender, smoking status, and comorbidities were questioned. A total of 50 patients (28 women; mean age 74.6 +/- 8.7 years) treated with warfarin in whom a transition to dabigatran was planned were included. Basal mean value of BDS (15.6 +/- 7.8 vs 11.5 +/- 4.8, P < .001) and HAS (16.8 +/- 10.4 vs 12.6 +/- 8.1, P < 0.001) was significantly higher in patients when they used warfarin than when they switched to dabigatran. In categorical analysis, frequency of patients with depression (mild, moderate, and severe) was significantly higher in period of warfarin use than after dabigatran transition (n = 24, 48% vs n = 14, 28%, P = .039). Our study demonstrates that patients with nonvalvular AF under treatment of dabigatran had lower BDS and HAS scores compared to warfarin. These findings suggest that dabigatran may increase quality of life and decrease morbidity and mortality due to reduction in anxiety and depression.

    Dipper ve non-dipper hipertansiyon ile miyokard perfüzyon sintigrafisinde yalancı pozitiflik ilişkisi
    (Düzce Üniversitesi, 2017) Aytekin, Seda; Kayapınar, Osman
    AMAÇ: Biz bu çalışmamızda tamam hipertansif olan, göğüs ağrısı şikayeti ile başvuran hastalarda dipper ve non-dipper hipertansiyon ile sintigrafide yalancı pozitiflik ilişkisini incelemeyi amaçladık. YÖNTEM: Düzce üniversitesi kardiyoloji polikliniğimize göğüs ağrısı şikayetiyle başvurup, miyokard perfüzyon sintigrafisi istenen ve sintigrafisinde iskemi tespit edilen ancak koroner anjiografisinde kritik koroner arter hastalığı saptanmayan tamamı hipertansif 26 birey çalışmaya dahil edildi. Sintigrafisi anlamlı iskemi tespit edilmeyen göğüs ağrısı şikayetinin devamı üzerine koroner anjiografi uygulanan , anjiografisinde kritik darlık saptanmayan orta risk grubundaki 11 hasta kontrol grubu olarak alındı. BULGULAR: Çalışmamızda AKBM sonuçlarına göre maksimum sistolik gündüz ve gece, minimum sistolik gündüz ve gece, maksimum diastolik gündüz ve gece, minimum diastolik gündüz ve gece, ortalama 24 saat sistolik ve diastolik, ortalama gündüz sistolik ve diastolik ölçümleri, sistolik ve diastolik kan basıncı düşme değerleri arasında anlamlı fark saptanmamıştır. SONUÇ: Sonuç olarak çalışmamızda dipper-nondipper hipertansif hastaların miyokard perfüzyon sintigrafisindeki yalancı pozitif sıklığını karşılaştırmayı ve irdelemeyi hedefledik.İki grup arasında anlamlı farklılık olmadığını bulduk. Bizim çalışmamızda anlamlı sonuçlara ulaşamamamızdaki temel sebepler, hasta sayısının yetersizliği (iskemik grup: 26 kişi , kontrol grubu: 11 kişi) ve bu hastaların içinde dipper HT hasta oranının çok düşük olması (iskemik grup: 7 kişi , kontrol grubu: 2 kişi) olarak değerlendirilebilir
