It is essential to emphasise that each minute of delay in providing medical care is negatively correlated to the patient\u2019s prognosis. The present study was carried out to evaluate the ischaemia-reperfusion times in patients \u226440 years of age versus individuals &gt;40 years of age and their association with mortality and major adverse cardiac event (MACE) over the long term.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>A retrospective, multicentre cohort study was carried out in 6799 patients diagnosed with STEMI.

A delay was observed in females, with a relative risk (RR) of 1.21 (95% CI 1.13 to 1.30) (p&lt;0.001). Presenting dyspnoea (RR 1.76, 95% CI 1.5 to 2.06) (p&lt;0.001) or going to a hospital without haemodynamics (RR 1.55, 95% CI 1.45 to 1.67) (p&lt;0.001) was related to increased delay. The occurrence of MACE in the first year of follow-up was related to different risk factors, along with a delay in healthcare (HR 1.25, 95% CI 1.10 to 1.54) (p&lt;0.042).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>This study shows that young patients with STEMI tend to receive a sooner diagnosis than older individuals.
