Although uric acid (UA) is considered as an antioxidant, the relationship between serum UA levels and cardiovascular diseases not clear yet. Higher brachial artery resting diameter (BD), impaired flow-mediated dilatation (FMD), increased carotid intima-media thickness (IMT), decreased aortic distensibility (AoD), stiffness index (AoSI) elastic modulus (AoEM) are predictors for development and/or progression of atherosclerosis. In this study, BD, FMD, IMT, AoD, AoSI AoEM were studied in...

The assessment of coronary flow reserve (CFR) by transthoracic Doppler echocardiography has recently been introduced into clinical practice, and reduced CFR suggested to be a sensitive indicator hypertensive end-organ damage; however, date, this methodology not used evaluate in subjects with prehypertension. Accordingly, the present study was designed prehypertension.We measured 40 prehypertension, 60 patients hypertension, 50 normotensive healthy volunteers using echocardiography. None had...

Abstract Background Statins improve endothelial functioning in patients with coronary artery disease and hypercholesterolemia, while substantially little is known about induced changes myocardial microcirculation. However, although previous studies have suggested that microvascular abnormalities dysfunction responsible for slow flow (SCF), there no study investigating possible effects of statins on function SCF. Hypothesis We prospectively investigated the short‐term lipid‐lowering therapy...

Epicardial adipose tissue (EAT) is a local source of various hormones, cytokines, and vasoactive substances affecting the myocardium. EAT contains abundant ganglionic plexi that interact with autonomic nervous system. Evidence association between arrhythmia limited, exception atrial fibrillation. This study aimed to investigate relation cardiac function using heart rate variability (HRV) turbulence (HRT) parameters.All subjects underwent 24-hour Holter recording assess HRV HRT parameters...

<i>Background:</i> Coronary flow reserve (CFR) reflects the functional capacity of microcirculation to adapt blood demand during increased cardiac work. In this study, CFR hemodialysis patients with angiographically normal coronary arteries was evaluated using transthoracic second harmonic Doppler echocardiography. <i>Methods and Results:</i> Ten patients, 14 sex-, age- left ventricular mass index-matched hypertensive controls underwent echocardiographic examination....

Paroxysmal atrial fibrillation might be a risk factor for stroke such as chronic fibrillation. We examined the relation between mean platelet volume and paroxysmal to determine effect of on thrombotic state via elevated volume. Mean is marker size, function, activation. Increased reflects active large platelets that release more thromboxane A2 than smaller ones. hypothesized in patients with The study population comprised 103 consecutive who were detected have by 24-h Holter monitoring 87...

METHODSThe medical reports of 5,548 patients who had undergone coronary angiography (CAG) between 2005 and 2009 were retrospectively investigated.Dominance pattern presence IMA CAA recorded.CAAs described using two different classifications: Angelini Khatami's classification, a new modified classification that was derived from classification.Some procedural details clinical features the with also investigated. RESULTSCoronary dominance was: 81.6% right artery, 12.2% circumflex artery 6.2%...

Anticoagulation is not justified unless atrial fibrillation (AF) detected in cryptogenic stroke (CS) patients. We sought to explore whether left (LA) remodelling associated with embolic of undetermined source (ESUS).In this prospective study, we evaluated consecutively 186 patients sinus rhythm who presented an acute ischaemic (embolic and non-embolic) sex- age-matched controls. performed continuous electrocardiogram (ECG) monitoring capture paroxysmal AF episodes as recommended by the...
