Relationship between self-management ability and major adverse cardiovas-cular events after PCI in elderly patients with coronary heart disease
Objective To explore the correlation between self-management ability and major adverse cardiovascular events(MACE)after percutaneous coronary intervention(PCI)in elder-ly patients with coronary heart disease,and to provide reference for reducing MACE in patients with coronary heart disease after PCI.Methods From February to June 2023,360 elderly pa-tients aged 60 and above who underwent PCI in three hospitals in Harbin,Heilongjiang Prov-ince were randomly selected for general demographic information and coronary heart disease self-management ability scale questionnaire survey.The influencing factors of MACE was ana-lyze by using binary Logistic regression;The dose-response relationship between self-manage-ment ability and MACE was analyzed by the restrictive cubic spline model.Results The re-sults showed that 146 elderly patients with coronary heart disease experienced MACE after PCI,with a detection rate of 40.56%.The self-management ability score of elderly patients with cor-onary heart disease was(72.31±9.31)scores.The multivariate Logistic regression results showed that age,duration of illness,alcohol consumption,triglycerides,and self-management ability were independent influencing factors for the occurrence of MACE in elderly patients with coronary heart disease after PCI(P＜0.05).The results of the restricted cubic spline model showed that after controlling for confounding factors,the correlation between self-management ability and MACE showed a non-linear dose-response relationship(non-linear test P＜0.001).Conclusion The incidence of MACE is higher in patients with coronary heart disease after PCI.MACE is influenced by age,duration of illness,alcohol consumption,triglycerides,and self-management ability.Clinical healthcare professionals should focus on high-risk groups,strengthen patient education,improve patients'self-management ability for coronary heart dis-ease,in order to reduce the occurrence of MACE.
