Abstract: Objective:To evaluate the clinical value of heart rate variability (HRV) in evaluation on the short-term major adverse cardiac events (MACE) in the patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI). Methods:A total of 160 AMI patients received PCI were collected and divided into control group (126 cases,there was no MACE during 3 months after PCI) and research group (34 cases,there was MACE during 3 months after PCI) according to the occurrence of MACE after operation. The main HRV indexes including SDNN,SDANN,SDNNIDX,PNN50,RMSSD,LF and HF of the patients in two groups were compared. The Gensini scores of coronary artery of each patient were calculated. The relationships of the main HRV indexes and the Gensini scores of coronary artery were analyzed. After 3 months of follow-up,the risk factors of the main HRV indexes to the occurrence of MACE were confirmed by multivariate Logistic analysis. Results: The main HRV indexes including SDNN,SDANN,SDNNIDX,PNN50,RMSSD and HF of the patients in research group were lower than those in control group (all P<0.05),but LF in research group was higher than that in control group (P<0.05).The negative relationships between SDNN,SDANN,SDNNIDX and the Gensini scores were confirmed (r=-0.827,r=-0.789,r=-0.698, P<0.05),but rMSSD,pNN50,LF and HF had no relationship with the Gensini scores (P>0.05). The multivariant Logistic analysis showed that SDNN,SDANN,SDNNIDX were the independent protective factors to the occurrence of MACE (P<0.05). Conclusion:The HRV indexes indicating the sympathetic nervous system function can inflect the degree of coronary artery stenosis and assess the short-term prognosis in the AMI patients after PCI.
