The primary outcomes of dizeases study were all-cause mortality Angiohenesis MACE, and the second outcomes were revascularization, LVEF and CCS angina class.

When the data of outcome was unavailable, we will try to connect the corresponding author. Two investigators TL and ZSS assessed the risk of bias of the included studies with the Cochrane tool. Disagreements were resolved through discussing with a third investigator FCG.

I 2 statistic was used to measure the heterogeneity among the studies. Meta-regression analysis was conducted for the factors that affected the research results, such as the baseline LVEF values and baseline CCS angina class, to observe their impact on outcomes.

If necessary, subgroup analysis based on factors such as type of IHD, categories of growth factors, injection methods and follow-up duration was conducted to clarify their impact on outcome.

Sensitivity analysis was used to observe whether the results were reliable after the studies were excluded one by one.

The data were analyzed with Stata version The process of study selection was shown as Figure 1. Six hundred and fifty-nine articles from PubMed, from EMBASE, from CENTRAL, and 13 additional records identified through literature review were identified.

Ninety-four articles were excluded for duplication, and remained irrelevant articles were excluded after screening titles and abstracts. Finally, 29 articles were included in this meta-analysis Voors et al.

The quality of included studies were assessed based on seven aspects of risk biases, including random sequence generation, allocation concealment, blinding of participants and personnel, blinding for outcome assessment, incomplete outcome data, selective reporting, and other potential sources of bias.

The results of quality assessment were shown as Figure 2. Overall, no attrition bias or reporting bias was observed, and the methods of random and blinding were considered to be adequate in this meta-analysis, but there was an unclear risk in allocation concealment.

FIGURE 2. Risk of bias. ARisk of bias summary: each risk of bias item for each included study; Brisk of bias graph: each risk of bias item presented as percentages across all included studies. The studies were published between and A total of IHD patients, aged from 56 to 72 years old, were included in the analysis.

Six of the 29 studies contained 2 arms Hedman et al. The GFs involved VEGF, EPO, HGF, and Granulocyte Colony-Stimulating Factor G-CSFof which VEGF was subtyped into phVEGF, VEGF-AVEGF-ArhVEGF, and VEGF-D. Overall, 29 studies involving IHD patients 1, patients in GF group and 1, patients in control group were included Table 1.

Fourteen studies Steppich et al. The results demonstrated that there was no statistical difference between the GF therapy group and the control group in decreasing all-cause mortality RR: 0. Results from sensitivity analysis showed that exclusion of any single study did not affect the overall estimate for the effects of GF on all-cause mortality.

We also performed subgroup analysis based on type of IHD, categories of growth factors, injection methods and follow-up duration, and the results showed that those factors did not influence the final effect size Supplementary Figures S1—S4 ; Table 2.

The results showed that GF therapy did not significantly decrease the risk of MACE compared to the control group RR: 0. Subgroup analyses based on type of IHD, categories of growth factors, injection methods and follow-up duration were performed, and the final results were not influenced Supplementary Figures S5—S8 ; Table 2.

Sensitivity analysis showed that deletion of any one study did not alter the overall estimate for the impact of GF on MACE. FIGURE 4.

The sensitivity analysis showed that exclusion of any single study did not affect the overall estimate for the effect of GF on revascularization.

According to the visual inspection of funnel plot, a slight asymmetry was observed in the analysis for the effects of GF on LVEF. The application of the trim-and-fill method did not change the effect size WMD 2. The funnel plots created for the visual analysis of the publication bias are presented in Figure FIGURE Publication bias.

To our knowledge, the present meta-analysis is the first time to evaluate the effects of GF for therapeutic angiogenesis on IHD patients. The results showed that GF for therapeutic angiogenesis improved LVEF detected by echocardiography, rather than decreased all-cause mortality, MACE and revascularization during follow-up period.

Furthermore, GF also did not improve the CCS angina class. Overall, these evidences supported that GF for therapeutic angiogenesis might be beneficial in improving cardiac function in short-term follow-up, however, they are not effective in decreasing hard endpoints, such as all-cause mortality and MACE.

Developing extensive collateral circulation in ischemic myocardium is a promising therapy for treating IHD.

Even though antiplatelet agent and statin are cornerstones for treating IHD, however, previous clinical studies showed that statin and aspirin was effective in decreasing VEGF levels and have no effects on promoting angiogenesis Dworacka et al.

Recently, animal studies showed that VEFG for therapeutic angiogenesis could promotes collateral circulation in mouse heart by recruiting endothelial progenitor cells, and subsequently rescue myocardial tissue after an ischemic insult Mallick et al. Transforming growth factor beta TGF-β1 induces pro-reparative phenotypic changes in epicardial cells in mice after myocardial infarction Dergilev et al.

However, in the present meta-analysis, we collect most comprehensive data regarding the effects of GF on all-cause mortality, MACE and revascularization, and we found that GF did not decrease the rate of all-cause mortality, MACE and revascularization.

Low heterogeneity was observed regarding these outcomes, which increased the robustness of the results.

Access options	To date, virtually all clinical trials have been carried out as monotherapy, which may not be sufficient to promote both angiogenic and arteriogenic activities. The missing components in current therapeutic regimens should be included in the future designs of clinical trials. Great efforts from different entities including collaborations of pharmaceutical companies and government-funded organizations should be put forward to achieve a beneficial outcome in the treatment of the most common and life threatening ischemic diseases.

LVEF is a quantitative marker to evaluate cardiac systolic function. previous study showed that patients with preserved left ventricular ejection fraction had lower one and 3-year mortality rates as compared with reduced left ventricular ejection fraction regardless of the acute coronary syndrome period onset Yahud et al. Our results showed that GF for therapeutic angiogenesis could increase LVEF by 2. The metabolism of GF might lead to a transient effect on cardiac function. Moreover, GF showed notable improvement in cardiac function in SCHD and MIHF with stable disease, while it had no efficacy in refractory CAD or STEMI with critical disease. For specific GF categories, VEGF and HGF showed dramatic improvement in LVEF, while EPO and G-CSF had no obvious efficacy. Interestingly, HGF has a beneficial synergistic effect with VEGF. There is a study identified that HGF prominently promotes the effects of VEGF on angiogenesis via the ets-1 pathway Tomita et al. Furthermore, in respect to the injection methods, gene transfer therapy is superior to protein injection therapy, because gene transfer can increase LVEF by 2. We consider that GF should be used more often in the treatment of IHD patients with stable disease conditions. In terms of treatment methods, a combination of multiple synergistic GFs application and more frequent administration can be used in future clinical practice, and the gene transfer mode of delivery is more effective. There are some limitations in our study. First, there are different injection method of GF, including intramyocardial injections and intracoronary infusion, which might lead to clinical heterogeneity. Thus, we performed subgroup analyses based on injection method, and the effect sizes did not change. Second, the sample size of included studies is relatively small and might lead to less robust results, we would update the meta-analysis when large-scale clinical studies publish. Third, the long-term persistence of the treatment effects is unknown. Most of the trials ranged in duration from 3 to 12 months. Thus, trim-and-fill method was used to evaluate the corrected effect size, and we found that the effect size remained unchanged. HQ, C-GF, and S-SZ conceived the study.
