Abstract：Objective To investigate the influence of interventional therapy in different time intervals on ventricular systolic synchronicity in patients with myocardial infarction.Methods The patients (n=92, male 47 and female 45) were chosen from Jan. 2013 to Jan. 2015, and then randomly divided into treatment group and control group (eachn=46). All groups were given anticoagulation therapy, and control group was given emergency percutaneous coronary intervention (PCI, duration from disease attack to PCI<12 h)) and treatment group was given delayed PCI (duration from disease attack to PCI≥12 h).Results After treatment, LVESVI [(33.98±4.56) mL/m2vs. (24.09±5.09) mL/m2] and LVEDVI [(61.93±6.33) mL/m2vs. (54.98±5.91) mL/m2] decreased, LVEF [(51.94±5.55)%vs. (58.29±5.13)%] increased in treatment group compared with control group (all P<0.05). After treatment, Trs-Avg-12 was significantly lower in treatment group than that in control group [(400.33±26.55) svs. (420.10±20.31) s,P<0.05]. The incidence of major adverse cardiovascular and cerebrovascular events was 10.9%in treatment group and 41.3% in control group (P<0.05).Conclusion The delayed PCI can improve heart function and recovery of ventricular systolic synchronicity with higher safety besides of maintaining success rate compared with emergency PCI.
