Left atrial volume index: Can it provide additional prognostic information in ST-segment elevation myocardial infarction treated with primary percutaneous coronary intervention?
Introduction: We sought to assess the prognostic impact of left atrial (LA) size on long-term outcomes of ST-segment elevation myocardial infarction (STEMI). Methods: We studied 200 consecutive patients admitted to a single center between January 2010 and December 2014 with non-fatal STEMI treated w...

Introduction: We sought to assess the prognostic impact of left atrial (LA) size on long-term outcomes of ST-segment elevation myocardial infarction (STEMI). Methods: We studied 200 consecutive patients admitted to a single center between January 2010 and December 2014 with non-fatal STEMI treated with primary percutaneous coronary intervention (pPCI) who underwent a comprehensive echocardiographic examination at discharge. LA volume was estimated by the area-length method. The left atrium was classified as normal, mildly, moderately or severely enlarged by LA volume index (LAVI). The endpoints were defined as all-cause mortality, a cardiac composite endpoint (all-cause mortality, reinfarction, unplanned revascularization and hospitalization for heart failure) and a cardiovascular composite endpoint (cardiac endpoint plus atrial fibrillation and ischemic stroke) during follow-up. Results: In this STEMI population, 58% had normal LA size, 22.5% had mild LA enlargement, 10% had moderate LA enlargement and 9.5% had severe LA enlargement. During a median follow-up of 28 (IQR 21-38) months, 14 (7.0%) patients died, 53 (26.5%) had the cardiac and 58 (29%) the cardiovascular composite endpoints. There was a stepwise increase in the incidence of all-cause mortality (p=0.020) and both cardiac (p<0.001) and cardiovascular (p<0.001) endpoints with each increment of LAVI class. In multivariate analysis, severe LA enlargement by LAVI was an independent predictor of all-cause mortality (HR: 11.153; 95% CI: 1.924-64.642, p=0.007) and the cardiac (HR: 4.351; 95% CI: 1.919-9.862, p<0.001) and cardiovascular (HR: 4.351; 95% CI: 1.919-9.862, p<0.001) endpoints during follow-up. Conclusions: This contemporary study confirms the prognostic effect of LA size at discharge, applying the most recent reference values in STEMI patients treated with pPCI. Resumo: Introdução: Este estudo procurou avaliar o impacto prognóstico da dimensão da aurícula esquerda (AE) no enfarte agudo do miocárdio com supradesnivelamento do segmento ST (EAMCSST). Métodos: Foram estudados 200 doentes consecutivos, admitidos num único centro por EAMCSST não fatal, submetidos a intervenção coronária percutânea primária (ICPp) entre janeiro de 2010 e dezembro de 2014, que realizaram ecocardiograma à alta. O volume da AE foi calculado pelo método area-length. A AE foi classificada como normal ou ligeira, moderada ou severamente dilatada pelo volume indexado. Os endpoints primários foram a mortalidade por todas as causas, um endpoint composto cardíaco (morte, re-enfarte, revascularização não planeada e admissão por insuficiência cardíaca) e outro cardiovascular (endpoint cardíaco, fibrilhação auricular e acidente vascular cerebral isquémico) no follow-up. Resultados: Em 58% dos doentes a AE tinha dimensões normais e 22,5% apresentavam dilatação ligeira, 10% dilatação moderada e 9,5% dilatação severa. Durante um follow-up mediano de 28(IIQ 21-38) meses, 14 (4%) doentes morreram, 53(26,5%) tiveram o endpoint composto cardíaco e 58 (29%) o endpoint composto cardiovascular. A incidência de morte (p=0,020) e dos endpoints compostos cardíaco (p<0,001) e cardiovascular (p<0,001) no follow-up foi superior nos maiores graus de dilatação da AE. Na análise multivariada, a dilatação severa da AE foi preditora independente de morte (HR: 11,153; 95% CI: 1,924-64,642, p=0,007) e dos endpoints compostos cardíaco (HR: 4,351; 95% CI: 1,919-9,862, p<0,001) e cardiovascular (HR: 4,351; 95% CI: 1,919-9,862, p<0,001). Conclusões: Este estudo confirma a importância prognóstica do tamanho da AE na alta utilizando os valores de referência mais recentes nos EAMCSST submetidos a ICPp.
