24,183 | Paediatric/young versus adult patients with long QT syndrome. | Long QT syndrome (LQTS) is a less prevalent cardiac ion channelopathy than Brugada syndrome in Asia. The present study compared the outcomes between paediatric/young and adult LQTS patients.</AbstractText>This was a population-based retrospective cohort study of consecutive patients diagnosed with LQTS attending public... |
24,184 | Retrograde penetration pacing into the conduction system as an alternative approach of his-bundle pacing: Retrograde penetration pacing into the conduction system.<Pagination><StartPage>127</StartPage><EndPage>133</EndPage><MedlinePgn>127-133</MedlinePgn></Pagination><ELocationID EIdType="doi" ValidYN="Y">10.1016/j.jjc... | Ventricular tachyarrhythmias are a major cause of mortality and morbidity worldwide. Electrical defibrillation using high-energy electric shocks is currently the only treatment for life-threatening ventricular fibrillation. However, defibrillation may have side-effects, including intolerable pain, tissue damage, and wo... |
24,185 | LVS-HARMED Risk Score for Incident Heart Failure in Patients With Atrial Fibrillation Who Present to the Emergency Department: Data from a World-Wide Registry. | Background Heart failure (HF) is a common complication to atrial fibrillation (AF), leading to rehospitalization and death. Early identification of patients with AF at risk for HF might improve outcomes. We aimed to derive a score to predict 1-year risk of new-onset HF after an emergency department (ED) visit with AF. ... |
24,186 | Association of high serum soluble interleukin 2 receptor levels with risk of adverse events in cardiac sarcoidosis. | Although soluble interleukin 2 receptor (sIL-2R) is a potentially useful biomarker in the diagnosis and evaluation of disease severity in patients with sarcoidosis, its prognostic implication in patients with cardiac sarcoidosis (CS) is unclear. We sought to investigate whether sIL-2R was associated with clinical outco... |
24,187 | The Mayo Cardiac Intensive Care Unit Admission Risk Score is Associated with Medical Resource Utilization During Hospitalization. | To determine whether the Mayo Cardiac Intensive Care Unit (CICU) Admission Risk Score (M-CARS) is associated with CICU resource utilization.</AbstractText>Adult patients admitted to our CICU from 2007 to 2018 were retrospectively reviewed, and M-CARS was calculated from admission data. Groups were compared using Wilcox... |
24,188 | Left-sided vagus nerve stimulation improves cardiopulmonary resuscitation outcomes in rats as effectively as right-sided vagus nerve stimulation. | Our group previously reported that right-sided vagus nerve stimulation (RVNS) significantly improved outcomes after cardiopulmonary resuscitation (CPR) in a rat model of cardiac arrest (CA). However, whether left-sided vagus nerve stimulation (LVNS) could achieve the same effect as RVNS in CPR outcomes remains unknown.... |
24,189 | Protective effect of extracorporeal membrane pulmonary oxygenation combined with cardiopulmonary resuscitation on post-resuscitation lung injury. | Cardiac arrest (CA) is a critical condition that is a concern to healthcare workers. Comparative studies on extracorporeal cardiopulmonary resuscitation (ECPR) and conventional cardiopulmonary resuscitation (CCPR) technologies have shown that ECPR is superior to CCPR. However, there is a lack of studies that compare th... |
24,190 | Cyclic Variation of Spectral Parameters for the Differentiation of Atrial Myocardium Before and Immediately Following Radiofrequency Ablation. | Radiofrequency ablation (RFA) is a common treatment of atrial fibrillation. However, current treatment is associated with a greater than 20% recurrence rate, in part due to inadequate monitoring of tissue viability during ablation. Spectral parameters, in particular cyclic variation of integrated backscatter (CVIB), ha... |
24,191 | Study design and rationale of the pAtients pResenTing with cOngenital heaRt dIseAse Register (ARTORIA-R). | Due to improved therapy in childhood, many patients with congenital heart disease reach adulthood and are termed adults with congenital heart disease (ACHD). ACHD often develop heart failure (HF) as a consequence of initial palliative surgery or complex anatomy and subsequently require advanced HF therapy. ACHD are usu... |
24,192 | Echocardiographic Findings in Patients with Atrial Fibrillation in a Tertiary Care Center of Nepal: A Descriptive Cross-sectional Study. | Atrial fibrillation is the most prevalent supraventricular arrhythmia responsible for the large morbidity and mortality burden worldwide. There are various causes of atrial fibrillation that may affect the prognosis of patients. This study was intended to determine different echocardiographic findings in patients with ... |
24,193 | Doppler Mean Gradient Is Discordant to Aortic Valve Calcium Scores in Patients with Atrial Fibrillation Undergoing Transcatheter Aortic Valve Replacement. | Doppler mean gradient (MG) may underestimate aortic stenosis (AS) severity when obtained during atrial fibrillation (AF) because of lower forward flow compared with sinus rhythm (SR). Whether AS is more advanced at the time of referral for aortic valve intervention in AF compared with SR is unknown. The aim of this stu... |
24,194 | Pulse deficit in atrial fibrillation - a different perspective on rhythm or rate control strategy. | Pulse deficit (PD) is a frequently unused but crucial clinical finding in atrial fibrillation (AF) diagnosis.</AbstractText>We aimed to investigate the relationship between PD and exercise intolerance in AF patients to remodel the treatment in case of a favorable outcome.</AbstractText>This prospective study was conduc... |
24,195 | Surgical versus transcatheter aortic valve replacement in low-risk patients: A long-term propensity score-matched analysis. | Recent studies suggest the use of transcatheter aortic valve implantation (TAVI) as an alternative to surgical aortic valve replacement (SAVR) in lower risk populations, but real-world data are scarce.</AbstractText>Single-center retrospective study of patients undergoing SAVR (between June 2009 and July 2016, n =... |
24,196 | Heart failure and atrial flutter: a systematic review of current knowledge and practices. | While the interplay between heart failure (HF) and atrial fibrillation (AF) has been extensively studied, little is known regarding HF and atrial flutter (AFL), which may be managed differently. We reviewed the incidence, prevalence, and predictors of HF in AFL and vice versa, and the outcomes of treatment of AFL in HF... |
24,197 | The Path of Least Resistance. | A 72-year-old patient presented S/P defibrillation for ventricular fibrillation cardiac arrest. We present an interesting teaching electrocardiogram that demonstrates alternating right and left bundle branch blocks, as well as an atrioventricular block that illustrates this patient's complex conduction s... |
24,198 | A Pleasant Surprise in the Face of ST-Segment Elevation. | ST-segment elevation is a dreadful finding in the emergency department because it is often associated with myocardial infarction and demands a prompt and definitive treatment. However, the clinical and echocardiographic assessment of a patient with electrocardiographic changes trumps any electrocardiology expert and sh... |
24,199 | Wide Complex Tachycardia and Flecainide: A Dangerous Couple. | Differential diagnosis of wide complex tachycardia in patients taking anti-arrhythmic can be challenging. Conventional ECG diagnostic criteria are poorly specific and should be applied with caution. Patients who develop life-threatening arrhythmias after flecainide infusion should be screened for Brugada Syndrome, espe... |
