Prognostic impact of serum chloride concentrations in acute heart failure patients: A systematic Rreview and meta-analysis.

Objective: Acute heart failure (AHF) is a common disease in the emergency departments. Its occurrence is often accompanied by electrolyte disorders, but little attention is paid to chloride ion. Recent studies have shown that hypochloremia was associated with poor prognosis of AHF.

Intracardiac vs. transesophageal echocardiography for guiding transcatheter closure of interatrial communications: a systematic review and meta-analysis.

Background: Transcatheter closure of atrial septal defect (ASD) and patent foramen ovale (PFO) is an established practice, and it requires monitoring and guidance. Both transoesophageal echocardiography (TEE) and intracardiac echocardiography (ICE) can be used as guidance tools. However, the use of ICE and TEE in structural heart disease is controversial and the advantages and disadvantages of both for ASD and PFO closure need to be investigated.

Association of T-box gene polymorphisms with the risk of Wolff-Parkinson-White syndrome in a Han Chinese population.

Abnormal development of the atrioventricular ring can lead to the formation of a bypass pathway and the occurrence of Wolff-Parkinson-White (WPW) syndrome. The genetic mechanism underlying the sporadic form of WPW syndrome remains unclear. Existing evidence suggests that both T-box transcription factor 3 (TBX3) and T-box transcription factor 2 (TBX2) genes participate in regulating annulus fibrosus formation and atrioventricular canal development.

Intravenous diltiazem versus metoprolol for atrial fibrillation with rapid ventricular rate: A meta-analysis.

Background: Intravenous diltiazem and metoprolol are both commonly used to treat atrial fibrillation (AF) with rapid ventricular rate (RVR) in the emergency department (ED), but the advantages and disadvantages of these drugs cannot be verified. This meta-analysis aimed to assess the efficacy and safety of intravenous diltiazem versus metoprolol for AF with RVR.

Method: We systematically searched PubMed, Web of Science, Embase, Cochrane library, the China National Knowledge Infrastructure (CNKI), Wanfang, China Biology Medicine disc (CBM) and the WeiPu (VIP).

Modified Valsalva maneuver for treatment of supraventricular tachycardias: A Meta-analysis.

Backgroud: Valsalva maneuver (VM) is a simple and easy method for acute termination of supraventricular tachycardia (SVT), while a postural modification to the VM has been suggested to be superior to the standard VM (SVM). The objective of this meta-analysis is to explore the efficacy and safety of the modified VM (MVM) to terminate SVT compared with the SVM.

Methods: Extensive literature was conducted using the database such as PubMed, Embase, Web of Science, Cochrane library and included randomized controlled trials (RCTs) assessing the efficacy and safety of the MVM and SVM for SVT.
