Shensongyangxin Capsules for Paroxysmal Atrial Fibrillation: A Systematic Review of Randomized Clinical Trials.

ABSTRACT:

Objective

To evaluate the evidence for the effectiveness and safety of Shensongyangxin Capsules (SSYX) for treating paroxysmal atrial fibrillation (PAF).

Methods

We searched for randomized clinical trials for SSYX in PAF up to June 2015. The Cochrane risk of bias tool was used to assess the methodological quality. RevMan 5.3 was used to synthesize the results.

Results

We included 22 trials involving 2,347 PAF patients. The quality of the included studies was generally poor. The results of the meta-analysis showed that SSYX plus routine treatment was more effective at improving P-wave dispersion (Pwd) and the frequency of PAF attacks compared with routine treatment alone. The results from the included trials that compared SSYX plus routine treatment and arrhythmic drugs plus routine treatment were inconsistent. Trials reported on Pwd, quality of life, frequency of PAF attacks or maintenance rate of sinus rhythm and found that SSYX combined with anti-arrhythmic drugs plus routine treatment was more effective than anti-arrhythmic drugs plus routine treatment. Four of the trials reported adverse events, indicating that SSYX was potentially safer than anti-arrhythmic drugs.

Conclusions

There appears to be some benefit from the use of SSYX. However, due to poor methodological quality, we could not draw confirmative conclusions regarding the beneficial effect of using SSYX.

Project description:BackgroundDuring recent years, systematic reviews of observational studies have compared digoxin to no digoxin in patients with atrial fibrillation or atrial flutter, and the results of these reviews suggested that digoxin seems to increase the risk of all-cause mortality regardless of concomitant heart failure. Our objective was to assess the benefits and harms of digoxin for atrial fibrillation and atrial flutter based on randomized clinical trials.MethodsWe searched CENTRAL, MEDLINE, Embase, LILACS, SCI-Expanded, BIOSIS for eligible trials comparing digoxin versus placebo, no intervention, or other medical interventions in patients with atrial fibrillation or atrial flutter in October 2016. Our primary outcomes were all-cause mortality, serious adverse events, and quality of life. Our secondary outcomes were heart failure, stroke, heart rate control, and conversion to sinus rhythm. We performed both random-effects and fixed-effect meta-analyses and chose the more conservative result as our primary result. We used Trial Sequential Analysis (TSA) to control for random errors. We used GRADE to assess the quality of the body of evidence.Results28 trials (n = 2223 participants) were included. All were at high risk of bias and reported only short-term follow-up. When digoxin was compared with all control interventions in one analysis, we found no evidence of a difference on all-cause mortality (risk ratio (RR), 0.82; TSA-adjusted confidence interval (CI), 0.02 to 31.2; I2 = 0%); serious adverse events (RR, 1.65; TSA-adjusted CI, 0.24 to 11.5; I2 = 0%); quality of life; heart failure (RR, 1.05; TSA-adjusted CI, 0.00 to 1141.8; I2 = 51%); and stroke (RR, 2.27; TSA-adjusted CI, 0.00 to 7887.3; I2 = 17%). Our analyses on acute heart rate control (within 6 hours of treatment onset) showed firm evidence of digoxin being superior compared with placebo (mean difference (MD), -12.0 beats per minute (bpm); TSA-adjusted CI, -17.2 to -6.76; I2 = 0%) and inferior compared with beta blockers (MD, 20.7 bpm; TSA-adjusted CI, 14.2 to 27.2; I2 = 0%). Meta-analyses on acute heart rate control showed that digoxin was inferior compared with both calcium antagonists (MD, 21.0 bpm; TSA-adjusted CI, -30.3 to 72.3) and with amiodarone (MD, 14.7 bpm; TSA-adjusted CI, -0.58 to 30.0; I2 = 42%), but in both comparisons TSAs showed that we lacked information. Meta-analysis on acute conversion to sinus rhythm showed that digoxin compared with amiodarone reduced the probability of converting atrial fibrillation to sinus rhythm, but TSA showed that we lacked information (RR, 0.54; TSA-adjusted CI, 0.13 to 2.21; I2 = 0%).ConclusionsThe clinical effects of digoxin on all-cause mortality, serious adverse events, quality of life, heart failure, and stroke are unclear based on current evidence. Digoxin seems to be superior compared with placebo in reducing the heart rate, but inferior compared with beta blockers. The long-term effect of digoxin is unclear, as no trials reported long-term follow-up. More trials at low risk of bias and low risk of random errors assessing the clinical effects of digoxin are needed.Systematic review registrationPROSPERO CRD42016052935.
