Effects of changes of risk factors in PCI patients on the incidence of cardiac adverse events

Abstract

Objective To investigate changes of risk factors in patients after percutaneous coronary intervention (PCI), and analyze the relationship between it and the risk of occurrence of adverse cardiac events. Methods Totally 868 patients after PCI in the follow-up database center of a tertiary hospital in Harbin from March to September 2012 were selected as the research object. 2 years after surgery, the changes of blood lipid, body mass index (BMI), smoking, blood pressure and other risk factors were analyzed. Results There was no significant change in BMI and systolic blood pressure 2 years after PCI compared with prior, while low-density lipoprotein cholesterol (LDL-C), triglyceride (TG) and total cholesterol (TC) significantly decreased compared with preoperative, and high-density lipoprotein cholesterol (HDL-C) increased (P<0.05). In addition, risk stratification of adverse cardiac events was in the low-risk and intermediate-risk group 2 years after PCI, and it was significantly higher compared to the previous, and percentage of high-risk group and very high-risk group decreased (P<0.05). Conclusions The change of risk factors in PCI patients leads to the reallocation of risk stratification of cardiac adverse events, which reminds that medical staff should adhere to strengthening long-term secondary prevention interventions after PCI, to improve the quality of life of patients.
