Long-term prognostic significance of left atrial volume in acute myocardial infarction.
OBJECTIVES The aim of this study was to evaluate the significance of increased left atrial (LA) volume determined within the first 48 h of admission as a long-term predictor of outcome in patients with acute myocardial infarction (MI). BACKGROUND The LA volume reflects left ventricular (LV) diastolic properties. Whereas other LV Doppler diastolic characteristics are influenced by acute change...
متن کاملRelation of nonperfused myocardial volume and surface area to left ventricular performance in coronary microembolization.
BACKGROUND After occlusion of an epicardial artery, left ventricular (LV) dysfunction is closely related to the volume of nonperfused myocardium (NPM). The impact of coronary microembolization (ME) on LV function, however, is larger relative to the total volume of NPM. We hypothesized that the total surface area (SA), rather than the total volume, of NPM is the major determinant of ME-induced L...
متن کاملPredictors and prognostic value of left atrial remodelling after acute myocardial infarction
PURPOSE Left atrial (LA) volume is a strong prognostic predictor in patients following ST-segment elevation myocardial infarction (STEMI). However, the change in LA volume over time (LA remodelling) following STEMI has been scarcely studied. We sought to identify predictors for LA remodelling and to evaluate the prognostic importance of LA remodelling. METHODS This is a subgroup analysis from...
متن کاملEchocardiographic assessment of left atrial volume index in elderly patients with anterior wall myocardial infarction.
Enlarged left atrium (LA) predicts outcomes in patients with heart failure, atrial fibrillation and stroke. Left atrial volume (LAV) especially when corrected for body size (LAVi), is a more accurate representation of true LA size. Therefore we studied left atrial volume index (LAVi) in elderly patients with left ventricle anterior infarction and correlated LAVi with left ventricle ejection fra...
متن کاملLeft atrial volume: a powerful predictor of survival after acute myocardial infarction.
BACKGROUND After acute myocardial infarction (AMI), diastolic function assessed by Doppler echocardiography provides important prognostic information that is incremental to systolic function. However, Doppler variables are affected by multiple factors and may change rapidly. In contrast, left atrial (LA) volume is less influenced by acute changes and reflects subacute or chronic diastolic funct...
