Current clinical practice of cardiac resynchronization therapy in Turkey: Reflections from Cardiac Resynchronization Therapy Survey-II.

Objective: Cardiac resynchronization therapy (CRT) has been shown to reduce mortality in selected patients with heart failure with reduced ejection fraction (HFrEF). CRT Survey-II was a snapshot survey to assess current clinical practice with regard to CRT. Herein, we aimed to compare Turkish data with other countries of European Society of Cardiology (ESC).

Caseous calcification of the mitral annulus; scary image during robotic surgery.

Caseous calcification of the mitral annulus (CCMA) is a very rare form of mitral annular calcification (MAC). CCMA accounts for 0.63% of all cases and 0.

Relationship between Pulmonary Artery Stiffness and Functional Capacity in Patients with Heart Failure with Reduced Ejection Fraction.

Background And Objectives: Functional capacity varies significantly among patients with heart failure with reduced ejection fraction (HFrEF), and it remains unclear why functional capacity is severely compromised in some patients with HFrEF while it is preserved in others. In this study, we aimed to evaluate the role of pulmonary artery stiffness (PAS) in the functional status of patients with HFrEF.

Methods: A total of 46 heart failure (HF) patients without overt pulmonary hypertension or right HF and 52 controls were enrolled in the study.

Torsade de Pointes Triggered by Early Ventricular Escape Beats in a Patient with Complete Atrioventricular Block.

Torsade de pointes is an uncommon and malignant form of polymorphic ventricular tachycardia and associated with a prolonged QT interval, which may be congenital or acquired. Complete atrioventricular block may cause QT interval prolongation and torsade de pointes. In this paper, we present a case with complete atrioventricular block complicated with frequent episodes of torsade de pointes triggered by early premature ventricular contractions despite normal QT intervals.

Electrocardiographic estimation of successful ablation site in patients with manifest inferior paraseptal accessory pathway.

Inferior paraseptal accessory pathways (APs) have a wide distribution and prediction of AP location before radiofrequency ablation is very important in such pathways. We aimed to estimate successful ablation site based on electrocardiogram in 137 patients (mean age: 25.8±9.

Individual variations in ankle brachial index measurement among Turkish adults.

Purpose: Variability of ankle brachial index (ABI) measured by the same observer in the same individual on three different occasions was examined.

Basic Methods: A single morning ABI was initially determined (measurement 1) with handheld Doppler device. One to four weeks apart, another morning (measurement 2) and afternoon (measurement 3) ABI was measured on the same day.

Increased serum uric acid levels are correlated with decreased left atrial appendage peak flow velocity in patients with atrial fibrillation.

Objective: We aimed to examine the relationship between serum uric acid levels and left atrial appendage (LAA) peak flow velocity, an indicator of the mechanical functions of the LAA, and atrial fibrillation (AF).

Subjects And Methods: Transesophageal echocardiography was performed before cardioversion in 153 patients with AF. The patients were categorized into 2 groups based on their LAA blood flow velocity.

Relationship between neutrophil-to-lymphocyte ratio and electrocardiographic ischemia grade in STEMI.

Background: Neutrophil-to-lymphocyte ratio (NLR) has been found to be a good predictor of future adverse cardiovascular outcomes in patients with ST-segment elevation myocardial infarction (STEMI). Changes in the QRS terminal portion have also been associated with adverse outcomes following STEMI.

Objective: To investigate the relationship between ECG ischemia grade and NLR in patients presenting with STEMI, in order to determine additional conventional risk factors for early risk stratification.

The effect of age on right ventricular diastolic function in healthy subjects undergoing treadmill exercise test.

Objective: There is an increasing interest for the value of right ventricle (RV) in predicting exercise tolerance and prognosis in cardiovascular disease. However, there is relatively few data evaluating the effect of age on RV diastolic filling velocities during rest or exercise in healthy subjects.

Methods: A total of 54 healthy subjects were enrolled in this study.

Patients with drug-refractory atrioventricular nodal reentrant tachycardia: clinical features, electrophysiological characteristics, and predictors of medication failure.

Background And Purpose: Drug responses vary markedly from patient to patient in atrioventricular nodal reentrant tachycardia (AVNRT), the most common form of paroxysmal regular supraventricular tachycardia in adults. However, clinical and electrophysiological (EP) characteristics of patients with AVNRT whose tachycardia attacks could not be adequately controlled by antiarrhythmic agents have not been studied in a large patient cohort. We aimed to define the clinical and EP features of patients with drug-refractory AVNRT.

Traditional coronary risk factors in healthy Turkish military personnel between 20 and 50 years old: focus on high-density lipoprotein cholesterol.

Objective: Previous studies presented the Turkish population as a typical example of nations with low levels of high-density lipoprotein cholesterol (HDL-c). Nevertheless, some recent studies opposed this suggestion. We aimed to examine the traditional cardiovascular risk factors in young-middle age male military professionals, focusing especially on HDL-c.

Brain derived neurotrophic factor (BDNF) in cardiometabolic physiology and diseases.

Important advances in our understanding of the relationships between adipose tissue derived peptides, namely adipokines, and their effects on cardiovascular functions have been achieved in recent years. Growing knowledge of adipokine biology is revealing the complexity of these proteins. Adipose tissue releases some other proteins called neurotrophins that are mainly active in central and peripheral nervous system.
