Effect of a Media Campaign to Reduce Delay Times for Acute Myocardial Infarction on the Burden of Chest Pain Patients in the Emergency Department

We evaluated the effect of a media campaign aimed at reducing delay times in suspected acute myocardial infarction (AMI) on the volume of chest pain patients seen in the emergency department. During the 1st week of the campaign, the mean number of chest pain patients increased from 10.5 per day prior to the start to 25.4. However, the number declined rapidly in subsequent months. The greatest increase was observed in patients with chest pain in whom AMI was not suspected on examination. During the campaign, 4,805 patients with chest pain appeared in the emergency department as compared with 4,407 patients during the same time period prior to its start, an increase of 9%. The number of patients with confirmed AMI increased from 595 to 629 (6%).
