Mad honey poisoning is well known in the eastern Black Sea region of Turkey. The cause of the poisoning is the toxin grayanotoxin, found in honey obtained from the nectar of Rhododendron species on the mountains in the region. A 60-year-old man was brought to the emergency department with dizziness and syncope after eating a few spoonfuls of honey. While(More)
INTRODUCTION Changes of thyroid hormones levels may lead to effects, not only in ventricular function, but also atrial function. The aim of this study was to investigate left atrial (LA) mechanical functions, atrial electromechanical coupling and P wave dispersion in patients with subclinical thyroid disorders. MATERIAL AND METHODS Eighty patients with(More)
It is well known the relationship between oxidative stress and vascular function. However, association between total antioxidative capacity and arterial stiffness was not studied in patients with hypertension (HT). This study investigated whether total antioxidative capacity is associated with arterial stiffness and wave reflections. We studied 46 (age 48.5(More)
BACKGROUND/AIMS Abnormalities in atrial electromechanical delay (EMD) times and mechanical functions are considered as independent predictors of atrial fibrillation. However, to date, effects of a single hemodialysis (HD) session and acute volume-preload changes on atrial-EMD functions have not been investigated by Tissue Doppler Echocardiography (TDE). The(More)
BACKGROUND Arterial stiffness increases in hypertensive individuals. Arterial stiffness is associated with impairment of systolic and diastolic myocardial function in hypertension (HT). However, the relationship between arterial stiffness and serum heart-type fatty acid-binding protein (H-FABP) levels, a sensitive marker of myocardial damage, has not been(More)
BACKGROUND/AIMS This study aimed to evaluate the severity of obesity and its impact on achieving target blood pressure and metabolic derangement in obese individuals. METHODS This cross-sectional and population-based study was conducted between January and December 2012. A total of 1837 consecutive obese patients admitted to our outpatient clinic were(More)
BACKGROUND We sought to validate total atrial conduction time (TACT) measurement via tissue Doppler imaging (TDI) by comparing the electrophysiological study (EPS) measurements of healthy subjects, according to age and sex. METHODS Eighty patients with normal EPS results were included. TACT was measured by EPS and TDI. For validation, the results of TDI(More)
BACKGROUND The role of endogenous relaxin on hypertensive cardiovascular damage remains unknown. We investigated the relaxin level and its relation to cardiovascular function in patients with never treated hypertension (HT). METHODS We studied 42 (47.8+/-10 years) never treated patients with HT and 40 age-matched (47+/-8.6 years) normotensive individuals.(More)
The Seventh Report of the Joint National Committee on the Prevention, Detection, Evaluation, and Treatment of High Blood Pressure classifies blood pressure (BP) as normal, prehypertension, and hypertension. Although it has been shown that there is a relationship between hypertension and arterial stiffness, there is not sufficient data about arterial(More)
Prolonging atrial conduction time, as measured by tissue Doppler imaging (TDI), is an independent predictor of new onset or recurrent atrial fibrillation (AF). We investigated atrial conduction time and cardiac mechanical function in patients with impaired fasting glucose (IFG) using echocardiography. Thirty patients with IFG (19 males and 11 females; age,(More)
