Abstract

Background:

Chronic heart failure (CHF), the final phase of various heart diseases, is a serious public health problem resulting in high hospitalization rates, mortality, and increasing health care costs. Nuanxin capsule (NXC), a Chinese herbal formula, has been widely used in the treatment of CHF. However, the safety and efficacy of NXC used in patients with CHF has been uncertain and there has been no standard clinical trial published to confirm this. Thus, we conduct a study to evaluate the safety and efficacy of NXC for CHF.

Methods:

The reference lists of randomized controlled trials and 8 electronic databases will be independently and systematically searched by 2 review authors in May 2018. Four English databases (EMBASE, PubMed, Cumulative Index to Nursing and Allied Health Literature [CINAHL], and Cochrane Central Register of Controlled Trials [CENTRAL]) and 4 Chinese databases (Chinese Biomedical Literature Database [CBM], Chinese National Knowledge Infrastructure [CNKI], Wanfang Database, and VIP Database) will be included. The primary outcomes will be assessed according to the function classification of New York Heart Association (NYHA). Data synthesis will be precisely computed using the RevManV5.3 software when a data-analysis is allowed. Methodological quality will be assessed according to Cochrane Handbook.

Results:

This study will provide a high-quality synthesis of current evidence of NXC for CHF from different aspects including the mortality, the function classification of NYHA.

Conclusion:

The conclusion of this systematic review will provide evidence to prove whether NXC is an effective therapeutic intervention for patient with CHF.

Conclusion:

PROSPERO registration number: PROSPERO CRD42018090003.
