Intravenous Diltiazem Versus Metoprolol in Acute Rate Control of Atrial Fibrillation/Flutter and Rapid Ventricular Response: A Meta-Analysis of Randomized and Observational Studies.

Background: Atrial fibrillation (AF) and/or atrial flutter (AFL) with rapid ventricular response (RVR) is a condition that often requires urgent treatment. Although guidelines have recommendations regarding chronic rate control therapy, recommendations on the best choice for acute heart rate (HR) control in RVR are unclear.

Methods: A systematic search across multiple databases was performed for studies evaluating the outcome of HR control (defined as HR less than 110 bpm and/or 20% decrease from baseline HR).

Comparison of cardiac magnetic resonance imaging and fluorodeoxyglucose positron emission tomography in the assessment of myocardial viability: meta-analysis and systematic review.

Aim: Contrast-enhanced cardiac magnetic resonance (Ce-CMR) and Fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET) are frequently utilized in clinical practice to assess myocardial viability. However, studies evaluating direct comparison between Ce-CMR and FDG-PET have a smaller sample size, and no clear distinction between the two imaging modalities has been defined. To address this gap, we conducted a meta-analysis of studies comparing Ce-CMR and FDG-PET for the assessment of myocardial viability.

Can Artificial Intelligence Enhance Syncope Management?: A Multidisciplinary Collaborative Statement.

Syncope, a form of transient loss of consciousness, remains a complex medical condition for which adverse cardiovascular outcomes, including death, are of major concern but rarely occur. Current risk stratification algorithms have not completely delineated which patients benefit from hospitalization and specific interventions. Patients are often admitted unnecessarily and at high cost.

Is Virtual Learning Here to Stay? A Multispecialty Survey of Residents, Fellows, and Faculty.

The transition to virtual learning during the coronavirus disease 2019 pandemic marks a paradigm shift in graduate medical education (GME). From June to September 2021, we conducted a dual-center, multispecialty survey of residents, fellows, and faculty members to determine overall perceptions about virtual learning and assess its benefits, drawbacks, and future role in GME. We discovered a mainly positive view of virtual education among trainees (138/207, 0.

Novel Machine Learning Approach to Predict and Personalize Length of Stay for Patients Admitted with Syncope from the Emergency Department.

Background: Syncope, a common problem encountered in the emergency department (ED), has a multitude of causes ranging from benign to life-threatening. Hospitalization may be required, but the management can vary substantially depending on specific clinical characteristics. Models predicting admission and hospitalization length of stay (LoS) are lacking.

Comparison of cardiac magnetic resonance imaging and fluorodeoxyglucose positron emission tomography in the assessment of cardiac sarcoidosis: Meta-analysis and systematic review.

Aim: Fluorine-18 fluorodeoxyglucose-positron emission tomography (FDG-PET) and cardiac magnetic resonance (CMR) are frequently used advanced cardiac imaging to diagnose cardiac sarcoidosis (CS). We conducted a meta-analysis and systematic review to compare diagnostic parameters of FDG-PET and CMR in the diagnosis of cardiac sarcoidosis (CS).

Methods: We searched PubMed, EMBASE, and Scopus databases from their inception to 9/30/2021 with search terms "cardiac sarcoidosis" AND "cardiac magnetic resonance imaging" AND "positronemission tomography".

Meta-Analysis of Catheter Ablation Outcomes in Patients With Cardiac Sarcoidosis Refractory Ventricular Tachycardia.

Cardiac sarcoidosis (CS) frequently leads to ventricular tachycardia (VT), which is often refractory to antiarrhythmic and/or immunosuppressive medications and requires catheter ablation. We conducted a systematic review and meta-analysis to evaluate the role of catheter ablation in patients with refractory VT undergoing catheter ablation. We searched PubMed, Embase, and Scopus databases from their inception to December 31, 2021 with search terms "cardiac sarcoidosis" AND "electrophysiological studies OR ablation.

Predicting adverse cardiac events in sarcoidosis: deep learning from automated characterization of regional myocardial remodeling.

Recognizing early cardiac sarcoidosis (CS) imaging phenotypes can help identify opportunities for effective treatment before irreversible myocardial pathology occurs. We aimed to characterize regional CS myocardial remodeling features correlating with future adverse cardiac events by coupling automated image processing and data analysis on cardiac magnetic resonance (CMR) imaging datasets. A deep convolutional neural network (DCNN) was used to process a CMR database of a 10-year cohort of 117 consecutive biopsy-proven sarcoidosis patients.

The role of electrophysiology study in risk stratification of cardiac sarcoidosis patients: Meta-analyses and systemic review.

Background: The utility of an electrophysiologic study (EPS) in the risk stratification of cardiac sarcoidosis (CS) patients is not clear. We conducted a systemic review and meta-analysis to evaluate the utility of EPS in the risk stratification of CS patients.

Methods: We searched PubMed, Embase, and Scopus databases from their inception to 12/4/2020 with search terms "Cardiac sarcoidosis" And "Electrophysiological studies OR ablation".

Regional Myocardial Remodeling Characteristics Correlates With Cardiac Events in Sarcoidosis.

Background: The poor prognosis of cardiac sarcoidosis (CS) underscores the need for risk stratification.

Purpose: To investigate the prognostic significance of ventricular/myocardial remodeling features in sarcoidosis.

Study Type: Retrospective.

Temporal Trends in the Use of Therapeutic Hypothermia for Out-of-Hospital Cardiac Arrest.

Importance: Despite evidence that therapeutic hypothermia improves patient outcomes for out-of-hospital cardiac arrest, use of this therapy remains low.

Objective: To determine whether the use of therapeutic hypothermia and patient outcomes have changed after publication of the Targeted Temperature Management trial on December 5, 2013, which supported more lenient temperature management for out-of-hospital cardiac arrest.

Design, Setting, And Participants: A retrospective cohort was conducted between January 1, 2013, and December 31, 2016, of 45 935 US patients in the Cardiac Arrest Registry to Enhance Survival who experienced out-of-hospital cardiac arrest and survived to hospital admission.

Does acute care for the elderly (ACE) unit decrease the incidence of falls?

To determine whether acute care for the elderly (ACE) units decrease the incidence of patient falls compared to general medical and surgical (GMS) units, a non-concurrent prospective study included individuals aged 65 and older admitted to ACE or GMS units over a 2-year span was done. There were 7069 admissions corresponded to 28,401 patient-days. A total of 149 falls were reported for an overall incidence rate (IR) of 5.

Correlation of QT interval correction methods during atrial fibrillation and sinus rhythm.

The calculation of the corrected QT interval (QTc) is particularly problematic in patients during atrial fibrillation (AF). The aims of this study were to compare the QTc calculated using Bazett's formula in AF and sinus rhythm (SR) and determine whether alternative methods for QT correction were superior to Bazett's, in an effort to define the optimal method for QT correction in patients with AF. We evaluated consecutive patients with persistent AF admitted for initiation of dofetilide.

Clinical utility of a novel wireless implantable loop recorder in the evaluation of patients with unexplained syncope.

Background: The implantable loop recorder (ILR) is particularly useful for monitoring patients with syncope, given the episodic nature and unpredictable pattern of recurrent episodes. Current practice guidelines advocate ILR implantation in select patients with unexplained syncope.

Objective: The purpose of this study was to evaluate the clinical utility and potential advantages of a novel wireless ILR in a consecutive cohort of patients with unexplained syncope.
