Abstract 20326: Atypical Symptom Presentation is the Strongest Predictor for Prolonged Care-Seeking Delay in Patients With Acute Myocardial Infarction
Introduction: This study aimed to determine the predictors of prehospital delay in care seeking among the Chinese patients with acute myocardial infarction (AMI).
Methods: This multicenter cross-sectional study included 301 patients who were consecutively admitted with an index diagnosis of AMI in Hong Kong. Multiple regression analysis was used to examine the independent effects of various socio-demographic and clinical factors on prehospital delay in care seeking among AMI patients. A 5% level of significance was used for all statistical tests.
Results: The Chinese AMI patients in Hong Kong reported a median delay of 3.0 hours (interquartile range: 1.84 - 10.3 hours) before they seek medical treatment. The multiple regression analysis revealed that the independent predictors of longer care-seeking delay were older age (β = .212, p < .001), being female (β = .114, p = .048), diabetes mellitus (β = .141, p = .015) and having atypical symptom presentation (β = .293, p < .001), while predictors of shorter delay were having higher chest pain intensity (β = -.244, p < .001) and patients with ST-segment elevation myocardial infarction (β = -.133, p = .019). The overall model was significant, which explained 32% of the variance in care-seeking delay.
Conclusions: Prolonged delay in care-seeking remains a significant problem among Hong Kong Chinese AMI patients. The results of this study suggested that the characteristics of symptom presentation were the most significant predictors of care-seeking delay among Chinese AMI patients. Educational efforts should be directed to educate patients about the characteristics of AMI presentation, in particular the atypical symptoms.
