Key result
Late presentation in ACS does not affect in-hospital mortality, with risk driven by baseline comorbidities.
Why the study?
Does late presentation (≥ 12 hours) compared to early presentation (< 12 hours) increase in-hospital mortality in patients with acute coronary syndrome undergoing percutaneous coronary intervention?
Cohort (n=230)
No
Does late presentation (≥ 12 hours) compared to early presentation (< 12 hours) increase in-hospital mortality in patients with acute coronary syndrome undergoing percutaneous coronary intervention?
In a Mexican cohort of ACS patients, in-hospital mortality was high (20.4%) and primarily determined by clinical severity and comorbidities rather than delayed presentation alone.

Bazo-Medina et al. (2026) conducted a cohort in Acute coronary syndrome (n=230). Late presentation (≥ 12 h) vs. Early presentation (< 12 h) was evaluated on In-hospital mortality (p=0.620). In patients with acute coronary syndrome, late presentation (≥ 12 h) did not significantly affect survival compared to early presentation (p=0.620), with mortality primarily driven by clinical severity and comorbidities such as chronic kidney disease.
