Acutely onset amiodarone-induced angioedema in a patient with new atrial fibrillation

Efficacy and safety of Shen-Song-Yang-Xin capsule for treating arrhythmia in the elderly patients with coronary heart disease: Protocol for a systematic review and meta-analysis

BACKGROUND

Coronary heart disease (CHD) is a major cause of mortality worldwide. Shen-Song-Yang-Xin capsule (SSYXC) has received extensive attention as an alternative therapy in improving myocardial ischemia and hypoxia effectively. In addition, there has been no systematic review or meta-analysis of SSYXC in the treatment of the elderly patients with cardiac arrhythmias in coronary heart disease (CHD). Therefore, we carry out a protocol of a proposed study based on the referred Reporting Items for Systematic Reviews and Meta-Analyses guidelines that aims to systematically evaluate the efficacy and safety of SSYXC in the elderly patients with cardiac arrhythmias in CHD.

METHODS

Two researchers will search 9 electronic databases (PubMed, Medline, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure, Chinese VIP Information, Wanfang Database, and Chinese Biomedical Database) to identify all studies that meet the inclusion criteria and were published before October 2018. The literature selection process will be reported in accordance with the PRISMA guidelines. After information extraction and methodological quality evaluation, we will use Stata 12.0 software (STATA Corporation, College Station, TX) to synthesize the data. The primary outcomes will include effective rates of treatment and improvements of electrocardiogram or 24 hours dynamic electrocardiogram result, and secondary outcomes will include improvement of relevant serological indexes, heart function classification and adverse events.

RESULTS

The data synthesis results will objectively illustrate the efficacy and safety of SSYXC in the elderly patients with cardiac arrhythmias in CHD.

CONCULSION

The findings will provide a reference for the use of SSYXC in the treatment of the elderly patients with cardiac arrhythmias in CHD.

The Role of Biologically Active Ingredients from Natural Drug Treatments for Arrhythmias in Different Mechanisms

Arrhythmia is a disease that is caused by abnormal electrical activity in the heart rate or rhythm. It is the major cause of cardiovascular morbidity and mortality. Although several antiarrhythmic drugs have been used in clinic for decades, their application is often limited by their adverse effects. As a result, natural drugs, which have fewer side effects, are now being used to treat arrhythmias. We searched for all articles on the role of biologically active ingredients from natural drug treatments for arrhythmias in different mechanisms in PubMed. This study reviews 19 natural drug therapies, with 18 active ingredient therapies, such as alkaloids, flavonoids, saponins, quinones, and terpenes, and two kinds of traditional Chinese medicine compound (Wenxin-Keli and Shensongyangxin), all of which have been studied and reported as having antiarrhythmic effects. The primary focus is the proposed antiarrhythmic mechanism of each natural drug agent. Conclusion. We stress persistent vigilance on the part of the provider in discussing the use of natural drug agents to provide a solid theoretical foundation for further research on antiarrhythmia drugs.
