Therapeutic Efficacy and Safety of Safflower Injection in the Treatment of Acute Coronary Syndrome.

Background Safflower injection (SFI), a popular Chinese patent drug, is commonly used to treat acute coronary syndromes (ACSs) in China. The research seeks to scientifically estimate the clinical efficacy of SFI for ACS patients. Methods Eight electronic databases were retrieved for eligible research from the founding date to September 8, 2020. Odds ratio (OR) was adopted to assess the total effective rate, ECG improvement, and adverse reaction, and mean difference (MD) was used for assessing the hemorheology indexes as well as the LVEF. Results Sixteen randomized controlled trials involving 1620 sufferers with ACS were incorporated. The outcomes showed that, in comparison to conventional medication alone, SFI combined with conventional treatment remarkably enhanced the total effective rate (OR = 3.66, 95% CI [2.73, 4.90], P < 0.00001), ECG improvement (OR = 2.85, 95% CI [2.04, 3.99], P < 0.00001), and LVEF (MD = 5.13, 95% CI [3.73, 6.53], P < 0.00001). Moreover, SFI combined with conventional treatment significantly decreased hemorheology indexes including BV (MD = -0.95, 95% CI [-1.76, -0.13], P=0.02), HCT (MD = -2.37, 95% CI [-3.25, -1.50], P < 0.00001), FIB (MD = -0.44, 95% CI [-0.60, -0.29], P < 0.00001), and PAR (OR = -7.65, 95% CI [-10.16, -5.14], P < 0.00001). However, no notable contrast was observed to link the experimental and the control team for PV (MD = -0.42, 95% CI [-0.83, 0.00], P=0.05) and adverse reactions (OR = 0.59, 95% CI [0.13, 2.74], P=0.50). Conclusion Despite the limitations that existed in this meta-analysis, the outcomes demonstrated that SFI and conventional combined medication is an effective and relatively safe therapy for ACS sufferers.
