BACKGROUND: The rapid acquisition of an electrocardiogram (ECG) plays a crucial role in the diagnosis and management decisions in patients with acute coronary syndrome (ACS).
OBJECTIVES: We determined the time-to-ECG acquisition, identified factors associated with timely acquisition, and evaluated the influence of time-to-ECG on in-hospital mortality.
METHODS: We measured the door-to-ECG time for 903 of 2140 patients in the emergency department of Far Eastern Memorial Hospital with a diagnosis of ACS from January 1, 2016 to December 31, 2018, via a retrospective chart review. The primary outcome was in-hospital mortality. Outcome analysis of mortality was conducted using multivariable logistic regression. The secondary outcome was to determine which factors influenced whether or not a patient received an ECG within 10 min. The analysis was conducted using multiple logistic regression.
RESULTS: The median time-to-ECG was 5 min (interquartile range: 4-11 min) in all patients. In multivariable logistic regression analysis, we found that older age and more severe heart-broken index were significantly related to timely ECG acquisition. In-hospital mortality was higher in those in whom ECG was performed after more than 10 min. However, in the multivariable logistic regression analysis, it did not have a significant positive correlation with ECG acquisition time.
CONCLUSIONS: Timely ECG acquisition owing to the triage protocol at our institution, the heart-broken index, led to early PCI and thus better outcomes for the ACS patients in this study. The implementation of a protocol-driven timely evaluation of patients with ACS and prompt PCI are important.
