BACKGROUND In the past decades, a large number of randomized controlled trials
(RCTs) on the efficacy of ligustrazine injection combined with conventional
antianginal drugs for angina pectoris have been reported. However, these RCTs
have not been evaluated in accordance with PRISMA systematic review standards.
The aim of this study was to evaluate the efficacy of ligustrazine injection as
adjunctive therapy for angina pectoris. MATERIAL AND METHODS The databases
PubMed, Medline, Cochrane Library, Embase, Sino-Med, Wanfang Databases, Chinese
Scientific Journal Database, Google Scholar, Chinese Biomedical Literature
Database, China National Knowledge Infrastructure, and the Chinese Science
Citation Database were searched for published RCTs. Meta-analysis was performed
on the primary outcome measures, including the improvements of
electrocardiography (ECG) and the reductions in angina symptoms. Sensitivity and
subgroup analysis based on the M score (the refined Jadad scores) were also used
to evaluate the effect of quality, sample size, and publication year of the
included RCTs on the overall effect of ligustrazine injection. RESULTS Eleven
RCTs involving 870 patients with angina pectoris were selected in this study.
Compared with conventional antianginal drugs alone, ligustrazine injection
combined with antianginal drugs significantly increased the efficacy in symptom
improvement (odds ratio [OR], 3.59; 95% confidence interval [CI]: 2.39 to 5.40)
and in ECG improvement (OR, 3.42; 95% CI: 2.33 to 5.01). Sensitivity and subgroup
analysis also confirmed that ligustrazine injection had better effect in the
treatment of angina pectoris as adjunctive therapy. CONCLUSIONS The 11 eligible
RCTs indicated that ligustrazine injection as adjunctive therapy was more
effective than antianginal drugs alone. However, due to the low quality of
included RCTs, more rigorously designed RCTs were still needed to verify the
effects of ligustrazine injection as adjunctive therapy for angina pectoris.
