Prognostic significance of ST segment changes in lead aVR in patients with acute inferior myocardial infarction with ST segment elevation.
BACKGROUND Patients with inferior wall ST segment elevation myocardial infarction (STEMI) are considered to be at lower risk than patients with anterior wall STEMI. Nonetheless, 30-40% of all acute inferior wall MI cases have a poor prognosis. AIM To assess the frequency of ST segment changes (elevation or depression) in lead aVR in inferior STEMI patients, and to determine the clinical cours...
متن کاملResolution of ST-segment depression: A new prognostic marker in ST-segment elevation myocardial infarction.
AIMS To evaluate the prognostic impact of ST depression resolution among patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary PCI in the Assessment of Pexelizumab in Acute Myocardial Infarction (APEX-AMI) trial. METHODS AND RESULTS In this study, 4729 of 5745 patients had analysable ECGs demonstrating concomitant ST-segment depression. Resolution of summation op...
متن کاملPrognostic significance of precordial ST segment depression during inferior myocardial infarction in the thrombolytic era: results in 16,521 patients.
OBJECTIVES We examined the prognostic significance of precordial ST segment depression among patients with an acute inferior myocardial infarction. BACKGROUND Although precordial ST segment depression has been associated with a poor prognosis, this correlation has not been adequately quantified, partly because of small sample sizes and methodologic limitations in previous studies. METHODS W...
متن کاملPrognostic significance of precordial ST-segment changes in acute inferior wall myocardial infarction.
STUDY OBJECTIVE To examine the clinical significance of precordial ST-segment changes in patients with acute Q-wave inferior wall myocardial infarction. DESIGN Prospective evaluation (clinical follow-up) of Q-wave inferior wall myocardial infarction over a 6-year period in patients who fulfilled the inclusion criteria. SETTING Coronary care unit at a university hospital. PATIENTS Two hund...
متن کاملSignificance of ST segment depression during paroxysmal supraventricular tachycardia.
During paroxysmal supraventricular tachycardia, patients frequently experience chest pain and marked ST segment depression suggesting acute myocardial ischemia. The purpose of this study was to assess whether ST depression during supraventricular tachycardia is caused by myocardial ischemia as reflected by net myocardial lactate production. Twenty-five patients (14 men, 11 women) who had a hist...
