CASTILLO COSTA, YANINA et al. ST-Segment Elevation ACS: Impact of Time to Diagnosis on Door-To-Balloon Time in the Real World. Data from the ARGEN-IAM-ST Registry. Rev. argent. cardiol. [online]. 2020, vol.88, n.6, pp.530-537. ISSN 1850-3748. http://dx.doi.org/10.7775/rac.es.v88.i6.19252.

Background:
Time elapsed from the onset of symptoms to diagnosis (TTD) can influence in achieving a door-to-balloon time <90 min (DBT <90 min).
Methods:
A retrospective analysis was performed on 1,518 patients prospectively and consecutively included in the ARGEN-AMI-ST registry. In 37.8% of cases. patients were treated with DBT <90 min and a median TTD of 120 min (IQR 60-266). The population was divided according to TTD above or below 120 min. A DBT <90 min was achieved more frequently in those with TTD <120 min: 44% vs. 32.2% (p <0.001) respectively.
Results:
In patients with in situ percutaneous coronary intervention (PCI) and TTD <120 min, DBT <90 min was achieved in 56% vs. 37.1% of cases with TTD >120 min (p <0.001). In referred patients, there were no differences in DBT <90 min according to TTD: 27.5% vs. 25.7% (p: 0.3). In patients admitted during working hours, DBT <90 min was achieved with TTD <120 min in 49.8% vs. 36.3% with TTD >120 min (p: 0.003), as well as in patients admitted during non-working hours: 41.9% vs. 30.4% (p <0.001). The independent predictors of achieving a DBT <90 min in the multivariate analysis were age <75 years: OR 1.57 (1.1-2.25; p: 0.01), PCI during working hours: OR 1.32 (1.04-1.67; p: 0.002), PCI in situ: OR 2.4 (1.9-3.0; p <0.001), having a pre-hospital ECG: OR 2.22 (1.73-2.86; p <0.001) and a TTD <120 min: OR 1.53 (1.23-1.9; p <0.001).
Conclusions:
In patients with TTD <120 minutes, a DBT <90 minutes is more frequently achieved, especially in those treated in situ and during working hours. In referred patients, only 1 in 3 achieves a DBT<90 min and there is no relationship with TTD.
