Can the development of atrial fibrillation in patients with ischemic heart failure with low ejection fraction be predicted?
Alpsoy, Şeref; Erselcan, Kubilay; Akyüz, Aydın; Özkaramanlı Gür, Demet; Topuz, Sahin; Topçu, Birol; Güler, Niyazi (Kare Publ, 2020)OBJECTIVE: Our aim is to determine the triggering factors of paroxysmal atrial fibrillation (PAF) in ischemic heart failure (HF) patients with low ejection fraction (EF). METHODS: Sixty patients were included in this study. ... -
Heart rate recovery may predict the presence of coronary artery disease
Akyüz, Aydın; Alpsoy, Şeref; Akkoyun, Dursun Çayan; Değirmenci, Hasan; Güler, Niyazi (Aves, 2014)Objective: We investigated whether post-exercise first minute abnormal heart rate recovery (HRR1) helps to predict the presence and severity of CAD, because of some confounding data. Methods: A cross-sectional, retrospective ... -

Maximal Exercise-Corrected QT as a Predictor of Coronary Artery Disease: Comparison of Simpler Heart Rate Corrections
Akyüz, Aydın; Alpsoy, Şeref; Akkoyun, Dursun Çayan; Değirmenci, Hasan; Güler, Niyazi (Korean Soc Cardiology, 2013)Background and Objectives: The relationship between QT prolongation and myocardial ischemia is widely known. Due to the limited value of ST depression, we aimed to evaluate, by using four simpler heart rate corrections ... -
A new approach to the measurement of heart rate in patients with chronic heart failure-Heart rate performance index: an observational study
Akyüz, Aydın; Alpsoy, Şeref; Akkoyun, Dursun Çayan; Güler, Niyazi (Aves, 2013)Objective: In order to evaluate the utility of the heart rate performance index (HRPI), which is obtained by dividing HR mean by the difference of HR max and HR min in the context of Holter monitoring, we sought to determine ... -
A Novel Deep Inspiration Maneuver for Difficult Transseptal Puncture
Aksu, Tolga; Güler, Tümer Erdem; Yalın, Kıvanç; Gölcük, Şükriye Ebru; Özcan, Kazım Serhan; Güler, Niyazi (Excerpta Medica Inc-Elsevier Science Inc, 2017)Transseptal puncture (TSP) may not be possible in cases of an elastic, aneurysmal, or thickened interatrial septum (IAS). During deep inspiration (DI), the chest wall expands and the diaphragm descends. This makes intrapleural ... -
Plasma urotensin II and neurokinin B levels in acute myocardial infarction and stable coronary artery disease
Akkoyun, Dursun Çayan; Akyüz, Aydın; Alpsoy, Şeref; Gürel, Ahmet; Güler, Niyazi; Değirmenci, Hasan; Gurkan, Umit (Turkish Soc Cardiology, 2015)Objective: This aim of the study is to investigate whether there are possible plasma urotensin-II (U-II) and neurokinin B (NKB) level changes in patients with acute myocardial infarction (AMI) or not and plasma urotensin-II ... -
Red cell distribution width and contrast-induced nephropathy in patients who underwent primary percutaneous coronary intervention reply
Akkoyun, Dursun Çayan; Akyüz, Aydın; Kurt, Ömer; Bilir, Bülent; Alpsoy, Şeref; Güler, Niyazi (Turkish Soc Cardiology, 2016)[No Abstract Available] -
Relationship between red cell distribution width and contrast-induced nephropathy in patients who underwent primary percutaneous coronary intervention
Akkoyun, Dursun Çayan; Akyüz, Aydın; Kurt, Ömer; Bilir, Bülent; Alpsoy, Şeref; Güler, Niyazi (Turkish Soc Cardiology, 2015)Objective: This study evaluated the relationship between contrast-induced nephropathy (CIN) and red cell distribution width (RDW) in patients who underwent primary percutaneous coronary intervention (PCI). Methods: A total ... -
The role of novel cytokines in inflammation: Defining peripheral artery disease among patients with coronary artery disease
Özkaramanlı Gür, Demet; Güzel, Savaş; Akyüz, Aydın; Alpsoy, Şeref; Güler, Niyazi (Sage Publications Ltd, 2018)Coronary artery disease (CAD) patients with concomitant peripheral artery disease (PAD) experience more extensive and calcified atherosclerosis, greater lesion progression and more common coronary events compared to patients ... -
Role of sympathetic cotransmitter galanin on autonomic balance in heart failure: an active player or a bystander?
Özkaramanlı Gür, Demet; Sagbas, Miray; Akyüz, Aydın; Güzel, Savaş; Alpsoy, Şeref; Güler, Niyazi (Turkish Soc Cardiology, 2017)Objective: Galanin, a cotransmitter similar to neuropeptide Y (NPY), aggravates autonomic imbalance in systolic heart failure (HF) by attenuating vagal tonus after burst sympathetic activity. In animal HF models, galanin ... -
Tools to improve the diagnostic accuracy of exercise electrocardiograms in patients with atypical angina pectoris
Özkaramanlı Gür, Demet; Akyüz, Aydın; Alpsoy, Şeref; Güler, Niyazi (Aves, 2018)Objective: Although frequently utilized, an exercise electrocardiogram (ECG) provides limited diagnostic accuracy in patients with atypical angina pectoris. The purpose of this study was to determine the possible incremental ...
