P-wave dispersion is defined as the difference between maximum and minimum duration recorded from multiple different-surface ECG leads. It has been known that increased reflect prolongation of intraatrial interatrial conduction time inhomogeneous propagation sinus impulses, which are well-known electrophysiologic characteristics in patients with atrial arrhythmias especially paroxysmal fibrillation. Extensive clinical evaluation performed assessment risk for fibrillation without apparent...
This study was designed to determine the relationship between serum uric acid level and presence severity of coronary artery disease (CAD).A total 1012 patients who underwent angiography were included in this study. All assessed for cardiovascular risk factors ongoing medications. Serum creatinine level, as well a fasting lipid profile blood glucose, measured all before procedure. The CAD by Gensini score.Of (mean age, 59.4 +/- 10.24 years), 680 men 58.7 10.5 years) 332 women 61.0 9.51...
Aims: The CHA₂DS₂-VASc scoring system has been widely used for stroke risk stratification in patients with atrial fibrillation, yet evidence regarding its prognostic value other critical settings remains limited. This study aimed to assess the utility of score predicting mortality acute myocardial infarction (AMI) who received veno-arterial extracorporeal membrane oxygenation (VA-ECMO) support following out-of-hospital cardiac arrest. Methods: retrospective included 41 AMI requiring VA-ECMO...
Increasing evidence-based indications for the implantation of permanent pacemakers (PMs) and implantable cardioverter defibrillators (ICDs) have led to an increase in rate device infections. The aim present study was evaluate infection frequency, clinical characteristics, risk factors, microbiologic therapeutic features patients with PM/ICD infections.Clinical demographic characteristics can affect infections.The group consisted 57 diagnosed treated infections our hospital. control this...
There are some clinical and echocardiographic parameters to predict paroxysmal atrial fibrillation (PAF), but more sensitive predictors needed. Tissue Doppler imaging may be a method for this purpose.Thirty-four patients with PAF 31 control subjects were studied. Time intervals from the beginning of P-wave A-wave lateral septal mitral right ventricular tricuspid annuli in tissue recorded. The differences between these gave mechanical delays between/within corresponding atria.There no groups...
Objective. This study examined the effects of low dialysate sodium on endothelial dysfunction (ED) as measured by flow-mediated dilatation (FMD) brachial artery in haemodialysis (HD) patients. Methods. Thirty HD patients (17 men; mean age: 48.4 ± 17.8 years) were studied. Subjects underwent two consecutive 6-week periods. Dialysate was 143 mEq/L first period (standard Na HD) and 137 second (low HD). After each period, we performed FMD, echocardiographic evaluation 24-h ambulatory blood...
AimsCardiac resynchronization therapy (CRT) improves systolic function in heart failure (HF). However, the effects of CRT on left ventricular (LV) diastolic are not fully understood. The aim this study was to determine clinical and echocardiographic correlates improvement LV after CRT.
Background: Catheter ablation of atrial fibrillation is recommended for patients with symptomaticparoxysmal (PAF) despite anti-arrhythmic drugs (AADs). Radiofrequency widely accepted as an effective treatment PAF. Cryoenergy by cryoballoon technique alternative to radiofrequency (RF) ablation. Cryoballoon safe, andhas a similar success rate in comparison RF AF recurrence ablationis roughly 30%. The aim this study determine the predictors recurrenceafter Methods and Results: Sixty one...
Objective We aimed to investigate the association of fragmented QRS (fQRS) with subclinical left ventricular (LV) dysfunction in patients chronic kidney disease (CKD).Methods and results Patients CKD who had a normal LV ejection fraction (≥ 50%) were enrolled. The tissue Doppler-derived Tei index was measured for all patients. A ≥ 0.5 considered abnormal. Subclinical defi ned as presence an abnormal absence impaired (< 50%). fQRS additional R wave (R’) or notching S fragmentation two...
Ventricular arrhythmias can be seen in systemic sclerosis (SSc) patients and are thought to a result of fibrosis or ischemia the ventricular myocardium. Tp-e interval Tp-e/QT ratio electrocardiographic (ECG) indices predict tachyarrhythmia cardiovascular mortality. We aimed evaluate with SSc.A total 107 SSc (mean age, 48.6 ± 14.0 years; 96 females) 100 healthy controls 49.4 8.6 90 were enrolled. The standard 12-lead ECG was recorded; QTc, measured. Modified Rodnan skin severity score...
Background: Although predictive value of heart rate recovery (HRR) has been tested in large populations, the reproducibility HRR treadmill exercise test not assessed prospectively.This prospective study examined whether index test-retest stability short term.Methods: A total 52 healthy volunteers without cardiovascular risk factors (mean age, 30 ± 10 years, females) underwent standardized graded test, and was repeated on 7th 30th days.The subjects' maximal rates decrease from peak level to...
Alcohol septal ablation (ASA) has been shown to be an effective treatment in patients with hypertrophic obstructive cardiomyopathy (HOCM) who are refractory medical treatment. We describe alternative approach for glue (cyanoacrylate), which is particularly useful the collateral formation right coronary artery whom ASA contraindicated.In our method left ostium was cannulated 6-8F guiding catheter. Septal branch a 4F catheter and microcatheter then cyanoacrylate mixture instilled into artery....
Evaluating patients with symptoms suggestive of acute coronary syndrome (ACS) is a time consuming, expensive and problematic process in the emergency department. This study aimed to evaluate diagnostic prognostic value glycogen phosphorylase isoenzyme-BB (GP-BB) ACS.A total 72 (mean age 61.8 ± 11.6 years) ACS were enrolled. The ELISA method for determining GP-BB level was performed considered positive at 〉 10 ng/mL. Duration angina, type ACS, demographic features, myoglobin, creatinine...
The aim of the present cross-sectional study was to evaluate heart rate recovery (HRR) in normotensive and hypertensive individuals with either nondipper or dipper type circadian rhythm blood pressure. Eighty-five patients were divided into 4 groups according presence hypertension pattern pressure as follows: (1) normotensive/dipper, n=20; (2) normotensive/nondipper, n=21; (3) hypertensive/dipper, n=22; (4) hypertensive/nondipper, n=22. HRR indices calculated by subtracting first, second,...
Pulmonary hypertension (PH) is a life-threatening complication of systemic lupus erythematosus (SLE). in SLE has variety causes. Diagnosing early and defining the cause PH accurately can provide better clinical outcome SLE. We investigated causes characteristics patients with SLE.One hundred twenty-one who had visit 6-month period were assessed retrospectively. Patients ever systolic pulmonary arterial pressure 40 mm Hg or greater by Doppler echocardiography considered to have PH.Among 122...
