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...

It has been shown that the fragmented QRS (fQRS) on electrocardiogram (ECG) signifies regional myocardial scar in patients with non-Q-wave infarction (MI). We hypothesized presence of fQRS ECG may be related poorly-grown collateral coronary circulation (CCC) chronic total occlusion (CTO) without prior MI.This retrospective observational study is included 56 (mean age 61.73±7.96 years; 67.9% men) CTO one major arteries. Collateral was graded according to Rentrop's classification. The defined...

&lt;b&gt;&lt;i&gt;Objective:&lt;/i&gt;&lt;/b&gt; To evaluate left and right ventricular functions using tissue Doppler echocardiography (TDE) myocardial performance index (MPI) methods in patients with slow coronary flow (SCF) to determine the relationship between these parameters thrombolysis infarction frame count SCF patients. &lt;b&gt;&lt;i&gt;Subjects Methods:&lt;/i&gt;&lt;/b&gt; Thirty-five (20 males 15 females) who underwent angiography 35 age- sex-matched controls (14 21 without...

Cardiac autonomic dysfunction may develop in patients with clinical or subclinical thyroid hormone deficiency. Heart rate variability (HRV) and heart turbulence (HRT) are used for evaluating changes cardiac functions also to provide risk stratification noncardiac diseases. The aim of this study is evaluate before 6 months after replacement therapy deficiency.Forty hypothyroid (mean age 48 ± 13, four male) 31 healthy controls 51 12, three were included the study. Twenty-four hour ambulatory...

Abstract Red cell distribution width (RDW) was found to be a prognostic marker in heart failure patients. The aim of the study investigate relationship between RDW and echocardiographic parameters diastolic (DHF). Seventy‐one consecutive DHF patients (26 men) 50 controls (21 were included study. All population underwent evaluation, blood samples obtained. N‐terminal pro‐B‐type natriuretic peptide (NT‐proBNP) values significantly higher, whereas there an increasing trend for high‐sensitivity...

Myocardial fibrosis causes the fragmentation of QRS complexes (fQRS) on ECGs. We hypothesized that frequency fQRS could be more common in patients with rheumatoid arthritis (RA) than control subjects. A total 56 RA were compared 35 age- and gender-matched fibromyalgia subjects for fQRS. The was defined as presence an additional R wave, or notching S 2 contiguous leads corresponding to territory a major coronary artery. Patients bundle block ECG cardiovascular disease excluded. Twenty-one...

Objective: Contrast-induced nephropathy (CIN) is one of the most common causes acute renal failure in hospitalized patients.The direct toxic effect contrast media; ischemic damage caused by reactive oxygen species; increased perivascular hydrostatic pressure; high viscosity and changes activity vasoactive substances play important roles pathogenesis.Tadalafil inhibits phosphodiesterase enzyme which destroys nitric oxide.Nitric oxide vasodilatation, increases medullar blood flow mediates...

We aimed to investigate the association between aortic arch and coronary artery calcification (CAC). postulated that low- high-risk CAC scores could be predicted with evaluation of standard chest radiography for (AAC).Consecutive patients who were referred a multidetector computerized tomography (MDCT) examination enrolled prospectively. All scanned using commercially available 64-slice MDCT scanner score. A four-point grading scale (0, 1, 2 3) was used evaluate AAC on posterior-anterior...

Carboxy-terminal propeptide of type 1 procollagen (PICP) is a marker extracellular collagen synthesis. Fragmented QRS (fQRS) on 12-lead electrocardiogram (ECG) has been demonstrated as myocardial fibrosis. The present objective was to investigate the association between serum PICP concentration and presence fQRS ECG in hypertensive patients.Consecutive patients with previously or newly diagnosed hypertension were included. defined additional R-wave (R'), notching R- S-waves, fragmentation 2...

Abstract Background There was no scientific evidence about the initial treatment of hypertonic saline solution (HSS) in acutely decompensated heart failure (ADHF). Objectives This study assessed impact using HSS along with a loop diuretic (LD) as first for ADHF, focusing on renal function, electrolyte levels, and clinical outcomes. Methods In this retrospective case-control study, 171 adult patients (93 females/78 males) ADHF were included between January 1, 2022, December 31, 2022. Patients...

The objective of the present study was to compare early effects treatment with nebivolol and quinapril on endothelial function in hypertensive patients. A total 54 patients enrolled study. One groups (n = 27) received 20 mg/day, other group 5 mg/day for a period 4 weeks. dysfunction assessed using FMD (flow-mediated vasodilation) brachial arteries. baseline characteristics both were similar age, gender, left venticular ejection fraction, ventricular mass index, body index. No significant...

We hypothesized that frequency fQRS could be more common in patients with rheumatoid arthritis (RA) than control subjects. A total 56 RA were compared 35 age- and gender-matched fibromyalgia subjects for fQRS. The was defined as presence an additional R wave, or notching S 2 contiguous leads corresponding to territory a major coronary artery. Patients bundle block ECG cardiovascular disease excluded.

The aim of this study was to evaluate the association between mildly decreased glomerular filtration rate (GFR) and coronary collateral circulation (CCC).There would be an GFR CCC.Patients who had occlusion in at least 1 major artery were included study. Patients with severely moderately excluded. Patient data obtained from their files. To classify CCC, we used Rentrop classification. classified as having poor CCC (Rentrop grades 0 1) or good 2 3). We Modification Diet Renal Disease (MDRD)...

: Left ventricular (LV) thrombi are mostly formed in the aneurysmal or akinetic segment of LV apex. Thromboembolism to brain is usually fatal. There not enough information available regarding use these new oral anticoagulant agents thrombi. In this case, we present a 56-year-old male patient who was given dabigatran (150 mg, twice day) for paroxysmal atrial fibrillation after experiencing anterior myocardial infarction. During dabigatran, thrombus formation, which earlier, observed apical...
