Background Pathological Q waves are correlated with infarct size, and Q-wave regression is
associated with left ventricular ejection fraction improvement. There are limited data …

Objectives: In the present study, we investigated the association of pathological Q waves
with infarct size. Furthermore, we investigated whether Q-wave regression was associated …

Background Presence of Q waves on the presenting electrocardiogram (ECG) in patients
with ST‐segment elevation myocardial infarction (STEMI) has been associated with worse …

Q waves can develop early in infarction and indicate infarct progression better than symptom
duration. ST resolution (STR) is a predictor of reperfusion success. Our aim was to assess …

Abstract Background Pathological Q-wave (QW) in the electrocardiogram (ECG) before
primary percutaneous coronary intervention (primary PCI) is a strong prognostic marker in …

Background: The presence of pathological Q-waves in patients presenting with ST-elevation
myocardial infarction (STEMI) independently predicts 30-day mortality. A question that …

Background—Pathological early Q waves (QW) are associated with adverse outcomes in
patients with ST-segment–elevation myocardial infarction (STEMI). Primary percutaneous …

DESIGN: The data used for the present study were obtained as part of a clinical trial
evaluating the effect of thrombus aspiration after primary percutaneous coronary intervention …

Objectives: We assessed the incremental value of baseline Q waves over time from
symptom onset as a marker of clinical outcome in ST-segment elevation myocardial …

Objectives To evaluate quantitative relationships between baseline Q-wave width and 90-
day outcomes in ST-segment elevation myocardial infarction (STEMI). Background Baseline …
