Public Awareness of the Benefits of Aspirin Use in the Management of Acute Myocardial Infarction

Abstract

Background: Aspirin is known to be an effective agent in the tertiary prevention of acute myocardial infarction (AMI). The current recommendation is that aspirin should be given immediately during an AMI and continued afterward. Despite the recognized benefits of aspirin therapy, only a small portion of individuals take aspirin when experiencing acute chest pain. The objective of this study was to determine the proportion of the public that knew that aspirin administration during an AMI is beneficial and to examine factors associated with such knowledge. Methods: A telephone survey was completed by 976 people 40+ years of age, in Metro Vancouver, Canada. Results: Only 33.7% of the sample indicated that they were 'very likely' or 'definitely likely' to take an aspirin if they were experiencing symptoms of a heart attack. In multivariate analysis, older individuals, better educated individuals, and those with AMI experience in self, family member or friend, were more likely to report that they would take an aspirin. Chinese immigrants, compared with Canadian-born participants, were less likely to indicate that they would take an aspirin. Conclusions: Interventions for increasing awareness of the benefits of aspirin during an AMI should be made a priority in general, and with a particular focus on the Chinese-Canadian community. The purpose of this study was to determine the proportion of the public, in a large Canadian urban center, that knew that aspirin administration was recommended at the onset of symptoms suggestive of AMI. We also examined factors associated with such knowledge and whether individuals who had a history of AMI were more aware of the benefits of aspirin administration during AMI. This study was part of a larger investigation of socio- demographic, clinical, cognitive, psychological, and social factors associated with treatment seeking for cardiac symptoms. METHODS Sample, Data Collection, and Questionnaire This study used data collected from a telephone survey which was conducted as part of a larger study which is
