Key result
Preprocedural Q-wave depth is not associated with mortality in STEMI patients undergoing primary PCI.

Q-wave depth should not guide mortality risk assessment after primary PCI; leaves open its incremental value in larger multivariable models.

Does preprocedural Q-wave depth predict short- and medium-term mortality in STEMI patients undergoing primary PCI?
Preprocedural Q-wave depth does not serve as a standalone prognostic marker for mortality in STEMI patients undergoing primary PCI.
Arak et al. (2026) conducted a cohort in ST-Elevation Myocardial Infarction (STEMI) (n=625). Preprocedural Q-wave depth was evaluated on All-cause mortality at three and 12 months. Preprocedural maximal and average Q-wave depth were not associated with all-cause mortality at 3 or 12 months in STEMI patients undergoing primary PCI (overall 12-month mortality 7.4%).
