  "abstract": "Background:: Immediate coronary reperfusion is the cornerstone of therapy for acute ST-elevation myocardial infarction (STEMI), aiming to limit myocardial damage. Traditionally, the development of pathological Q waves on the electrocardiogram (ECG) has been considered a marker of irreversible transmural myocardial injury. However, most data on the incidence of pathological Q waves originate from the thrombolytic era. Therefore, the incidence and clinical significance of pathological Q waves in patients undergoing percutaneous coronary intervention (PCI) within the currently recommended time window remain unclear, as does the overall relationship with clinical outcomes.\n\nMethods:: This study included 116 patients with STEMI who underwent PCI. In accordance with the current European Society of Cardiology guidelines, treatment was initiated within the recommended 90 minutes after admission.\n\nResults:: Pathological Q waves developed in approximately 14% of patients, a lower incidence than that reported in the thrombolytic era. Pathological Q waves were more frequent among older patients, those with a lower baseline left ventricular ejection fraction (LVEF), and those with a longer time interval between admission and PCI. After adjustment for multiple variables, the presence of new pathological Q waves was not associated with an increased rate of one-year readmissions.\n\nConclusions:: In patients with STEMI undergoing PCI within the recommended time window, the incidence of pathological Q waves is substantially lower than that reported in the thrombolytic era and does not appear to be associated with a higher risk for readmissions. Further larger studies are warranted to confirm these findings.",
