The association of epicardial fat thickness with blunted heart rate recovery in patients with metabolic syndrome
Şengül, Cihan; Duman, Dursun (Tohoku University Medical Press, 2011)Epicardial fat tissue has unique endocrine and paracrine functions that affect the cardiac autonomic system. Epicardial fat thickness (EFT) and blunted heart rate recovery (HRR) are newly identified cardiovascular risk ... -

Comparison of fluoro and cine angiographic modes in coronary stenting procedure: A preliminary feasibility study
Olcay, Ayhan; Güler, Ekrem; Karaca, İbrahim Oğuz; Kızılırmak, Filiz; Olgun, Fatih Erkam; Yenipınar, Esra; Duman, Dursun (Elsevier, 2014)X-ray exposure of patient during coronary angiography (CA) and percutaneous coronary intervention (PCI) may have some deleterious effects. The radiation dose per frame for digital acquisitions can be 15 times greater than ... -
Comparison of fluoro and cine coronary angiography: Balancing acceptable outcomes with a reduction in radiation dose
Olcay, Ayhan; Güler, Ekrem; Karaca, İbrahim Oğuz; Omaygenç, Mehmet Onur; Kızılırmak, Filiz; Olgun, Erkam; Yenipınar, Esra; Çakmak, Hüseyin Altuǧ; Duman, Dursun (HMP Communications, 2015)Use of last fluoro hold (LFH) mode in fluoroscopy, which enables the last live image to be saved and displayed, could reduce radiation during percutaneous coronary intervention when compared with cine mode. No previous ... -
Coronary calcium score, albuminuria and inflammatory markers in type 2 diabetic patients: Associations and prognostic implications
Dayan, Akın; Narin, Burcu; Biteker, Murat; Aksoy, Şükrü; Fotbolcu, Hakan; Duman, Dursun (Elsevier, 2012)Aims: To investigate the relationship of coronary artery calcium (CAC) scores with common carotid artery intima media thickness (CCA-IMT), albuminuria and inflammatory factors in type 2 diabetes. Methods and results: 128 ... -
Correlation of pulse oximetry oxygen saturation with blood gas arterial oxygen saturation in patients with heart failure reduced ejection fraction: Prospective cohort study
Gök, Gülay; Çınar, Tufan; Nurkalem, Zekeriya; Duman, Dursun (Annals of Medical Research Publishing Inc, 2020)Abstract Aim: An estimation of accurate oxygen saturation is a critical in the management of patients with heart failure (HF).

Is increased epicardial fat thickness a marker of the presence of severe coronary artery disease?
Duman, Dursun (AVES, 2012)Fat is mainly deposited in subcutaneous tissue, but it also accumulates in the abdominal or thoracal region (1). Other major sites of fat accumulation are visceral and cardiac areas; Cardiac fat deposition is now recognized ... -
Is left ventricular diastolic dysfunction independent from presence of hypertension in metabolic syndrome? An echocardiographic study
