Résumé
BACKGROUND@#Reduced application of percutaneous coronary intervention (PCI) is associated with higher mortality rates after ST-segment elevation myocardial infarction (STEMI). We aimed to evaluate potential factors contributing to the refusal of PCI in STEMI patients in China.@*METHODS@#We studied 957 patients diagnosed with STEMI in the emergency departments (EDs) of six public hospitals in China. The differences in baseline characteristics and 30-day outcome were investigated between patients who refused PCI and those who underwent PCI. Multivariable logistic regression was used to evaluate the potential factors associated with refusing PCI.@*RESULTS@#The potential factors contributing to refusing PCI were older than 65 years (odds ratio [OR] 2.66, 95% confidence interval [CI] 1.56-4.52, P 12 h) (OR 3.31, 95% CI 1.83-6.02, P < 0.001) and not being hospitalized in a tertiary hospital (OR 0.45, 95% CI 0.27-0.75, P = 0.002). Compared to men, women were older, were less often married, had a lower BMI and were less often hospitalized in tertiary hospitals.@*CONCLUSIONS@#Patients who were older, had lower economic or social status, and had poorer health status were more likely to refuse PCI after STEMI. There was a sex difference in the potential predictors of refusing PCI. Targeted efforts should be made to improve the acceptance of PCI among patients with STEMI in China.
