  Figure 1. Kaplan-Meier curves of 5-years’ MACE for CCC patients. The significance level was 0.05. CCC = coronary collateral circulation; MACE = main cardiovascular event, including total death and recurrent hospitalization, PCI = percutaneous coronary intervention. 1) Above: for all enrolled AMI patients divided into non-CCC group and CCC group; Below: for all enrolled AMI patients divided into non-CCC group, poor CCC group, and good CCC group. 2) Censored cumulative survival for non-CCC and CCC (or poor and good CCC), the average cumulative survival time for non-CCC and CCC (or poor and good CCC), and the log rank test P value were: for Above, 79.3%, 73.1%, 49.84 ± 0.59 months, 47.54 ± 1.27 months, .070; for Below, 79.3%%, 72.7%, 73.2%, 49.84 ± 0.59 months, 48.76 ± 2.91 months, 47.21 ± 1.41 months, .174. 3) the following up time was 33.84 ± 16.87 months or 33.27 (24.00-48.00) months; 4) the followed up patients, total subjects and follow up rate were: non-CCC 1160, 1339, 86.63%, CCC 279, 323, 86.38%.

  Figure 2. Kaplan-Meier curves for CCC patients received PCI and matched Gensini score. The significance level was 0.05. CCC = coronary collateral circulation; MACE = main cardiovascular event, including total death and recurrent hospitalization, PCI = percutaneous coronary intervention. 1) Above: only including PCI treated patients; Below: by matching the Gensini score between non-CCC and CCC with propensity score matching method by SPSS 25 software. 2) Censored cumulative survival for non-CCC and CCC, the average cumulative survival time for non-CCC and CCC, and the log rank test p value were: Above, 79.8%, 73.3%, 50.14 ± 0.60 months, 47.73 ± 1.28 months, 0.062; Below, 76.0%, 73.1%, 49.38 ± 1.20 months, 47.47 ± 1.26 months, 0.279; 3) the following up time were: Above, 32.18 ± 16.77 months or 33.60 (24.00–48.00) months, Below, 33.82 ± 16.84 months or 36.00 (24.00–48.00) months; 4) the followed up patients, total subjects and follow up rate were: Above, non-CCC 1075, 1328, 80.95%, CCC 270, 310, 87.10%; Below, non-CCC 262, 325, 80.62%, CCC 279, 323, 86.38%.
