Abstract:
Objective:To explore the effect of sequel reperfusion percutaneous coronary intervention (PCI) therapy on heart rate variability (HRV) during myocardial reperfusion in patients with acute ST segment elevation myocardial infarction(STEMI).Methods:With a randomly case controlled study method, 180 patients with STEMI in Yidu Central Hospital Affiliated to Weifang Medical College were selected as study objects, and they were randomly divided into two groups: sequel recanalization PCI(sPCI) group(observation group) and conventional primary PCI(pPCI) group(control group), with 90 cases in each grouop.The rate of SDNN<70 mm of the two groups and other indicators of HRV were observed at 14 d after successful PCI.Results:There was statistically significant difference between the two groups in MBG3(77.78% vs.63.33%, χ 2=4.51, P=0.03). There was statistically significant difference between the two groups in the incidence of SDNN<70 mm at 14 d after PCI(10.00% vs.23.33%, χ 2=5.69, P=0.02). If sequel recanalization PCI was served as a variable for predicting SDNN<70 mm, the results of Logistic regression analysis showed that odds ratio ( OR) value was 0.36, 95% confidence interval ( CI) was 0.16-0.85, P=0.02.The other factors that affected the incidence rate of SDNN<70 mm were the level of MBG3( OR=0.45, 95% CI: 0.16~0.95, P=0.03), time-to-reperfusion( OR=2.65, 95% CI: 1.06~5.98, P=0.04), blood sugar level of admission ( OR=1.96, 95% CI: 1.04~7.71, P=0.04), TnI value( OR=2.06, 95% CI: 1.03~5.68, P=0.04), heart function( OR=2.18, 95% CI: 1.08~6.89, P=0.04). Conclusion:The sequel recanalization PCI may be better than conventional PCI for the patients with STEMI in obtaining myocardial blush grades.Meanwhile, it can increase the indicators of HRV and decrease the incidence rate of SDNN<70 mm.
