Chronic right ventricular (RV) apical pacing in patients with congenital complete atrioventricular block (CCAVB) is associated with left ventricle (LV) dyssynchrony and dysfunction. Hence, alternative...
This was a single-center, retrospective study in patients with CCAVB who underwent permanent pacemaker implant at age ≤ 18 years. Age- and gender-matched patients with a normal heart anatomy and funct...
We included 24 patients in the pacemaker group [27.6% male, mean age of 17.1 at last follow-up, follow-up duration of 8.7 years, RVSp (n = 9; 62.5%)] compared to 48 matched healthy controls. Shortenin...
STE was more sensitive in detecting subtle differences in LV function relative to standard conventional 2D echocardiography (SF and EF) in selected patients with CCAVB and a permanent pacemaker. Furth...
Sodium-glucose co-transporter 2 (SGLT2) inhibitors have beneficial effects in heart failure (HF), including reverse remodelling, but the mechanisms by which these benefits are conferred are unclear. I...
We measured C-reactive protein (CRP), tumor necrosis factor alpha (TNF-α), interleukin-1β (IL-1β), interleukin 6 (IL-6), and interleukin 10 (IL-10) and neutrophil-to-lymphocyte ratio (NLR) in plasma s...
Following 12 months of treatment dapagliflozin significantly reduced CRP compared to placebo (mean difference of -1.96; 95% CI -3.68 to -0.24, p = 0.026). There were no significant statistical changes...
Dapagliflozin caused a significant reduction in CRP compared to placebo. There were correlations between reductions in inflammatory markers including IL-1β and improvements in global longitudinal stra...
Clinicaltrials.gov NCT02956811 (06/11/2016)....
Right ventricular (RV) apical pacing can induce both interventricular dyssynchrony and intraventricular dyssynchrony. Mechanical dyssynchrony after long-term RV apical pacing is associated with reduce...
We aimed to identify the short-term effects of the pacemaker RV lead position on remodeling of LV systolic functions....
The study included 30 patients who presented with an indication of permanent pacing and who underwent permanent single- or dual-chamber pacemaker insertion: 15 patients with RV apical pacing (RV apex)...
At the 3‑month follow-up, post-pacing 2D speckle tracking echocardiography revealed impairment of global longitudinal strain in all patients and intraventricular dyssynchrony was significantly increas...
In the short-term follow-up, 2D speckle tracking echocardiography showed more radial dyssynchrony in the apical location than in the non-apical location of RV lead. The RV septal pacing is a better al...

In chronic kidney disease, IgA nephropathy, and left ventricular diastolic dysfunction have prognostic significance as well. However, the relationship between diastolic dysfunction, arterial stiffness...
79 IgA nephropathy patients (aged 46 ± 11 years) and 50 controls were investigated. Tissue Doppler imaging was used to measure early (Ea) and late (Aa) diastolic velocities. Arterial stiffness was mea...
We compared the IgAN patients to a similar cardiovascular risk group with a preserved eGFR. A strong correlation was found between Ea/Aa and SI (p < 0.001), also with PWVao (p < 0.001), just in IgAN, ...
In chronic kidney disease, increased cardiac rigidity and vascular stiffness coexist with decreased renal function, which is directly connected to diastolic dysfunction and vascular stiffness. On the ...
Left ventricular dysfunction and remodeling can occur as a result of aortic valve stenosis (AS). Three-dimensional speckle tracking echocardiography (3D-STE) can detect early left ventricular myocardi...
This study included 46 patients with asymptomatic severe AS but preserved LV systolic function (mean age 50.11 ± 12.66 years, LVEF 63.78 ± 3.95%, AS group) and 33 healthy subjects with no cardiovascul...
The AS group had significantly thicker interventricular septum and posterior ventricular wall than the control group (1.49 ± .19 cm vs. .81 ± .09 cm, p < .001; 1.73 ± 1.71 cm vs. .81 ± .10 cm, p = .00...
Our findings showed reductions in left ventricular global myocardial strains, particularly PSLS in patients suffering from asymptomatic severe AS in Bangladesh; this is consistent with other studies. ...
Data derived by cardiac magnetic resonance (CMR) feature tracking suggest that not only left ventricular but also left atrial function is impaired in patients with acute myocarditis. Therefore, we inv...
30 patients with acute myocarditis confirmed by CMR according to the Lake Louise criteria and 20 healthy controls were analyzed including global longitudinal strain (GLS) and left atrial (LA) strain p...
In patients with acute myocarditis and preserved LVEF not only GLS but also LA reservoir function, LA conduit function and left atrial stiffness index as well as left atrial filling index were impaire...
Left ventricular (LV) ejection fraction (LVEF) is not a sensitive marker of LV systolic function in a subset of patients with preserved EF. The relation between LV pump function and global longitudina...
In total, 100 participants with LVEF of ≥50% were studied for demographic and echocardiographic data, including LVEF, stroke volume, SVI, COP, LV longitudinal strain assessments, apical 4-, 3-, and 2-...
Reduced LV GLS was associated with lower SVI (35.6 ± 13.6 vs. 43.8 ± 12.7 mL/m 2 ; P = 0.01), lesser COP (5.4 ± 1.9 vs. 6.5 ± 2.1 l/min; P = 0.02), GLS had strong positive correlations with SVI ( r = ...
Impaired LV strain is associated with lower LV pump function, presented as lower COP and lower SVI in patients with preserved EF even in the absence of clinical HF. It is of great importance to incorp...
The response to the increase in heart rate (HR) could be characterized by failure in both left ventricular (LV) and left atrial (LA) functions. This study aimed to evaluate the relationship between th...
In a group of patients with an implantable cardioverter defibrillator (ICD) or pacemaker, the atrial paced rhythm was progressively increased from 60 to 70, from 70 to 80, and from 80 to 90 beats per ...
Of the 45 patients enrolled, a significant reduction in LAr was observed at higher HR. However, when the patients were dichotomized according to the HR-related response of LV-GLS, the worsening of LAr...
In patients with atrial paced rhythm, the increase in HR could be associated with worsening of LA and LV functions, as assessed by two-dimensional speckle tracking analyses. These results offer new da...
