The importance of integrated left atrial evaluation: From hypertension to heart failure with preserved ejection fraction

摘要: AIM Functional analysis and measurement of left atrium are an integral part cardiac evaluation, they represent a key element during non-invasive diastolic function in patients with hypertension (HT) and/or heart failure preserved ejection fraction (HFpEF). However, dysfunction remains quite elusive regarding classification, atrial size two factors for ventricular (LV) filling evaluation. Chronic (LA) remodelling is the final step chronic intra-cavitary pressure overload, it accompanies increased neurohormonal, proarrhythmic prothrombotic activities. In this systematic review, we aim to purpose multi-modality approach LA geometry analysis, which integrates flow characteristics through application both traditional new diagnostic tools. METHODS The most important studies published literature on size, HFpEF, HT fibrillation (AF) considered discussed. RESULTS HFpEF HT, pulsed tissue Doppler assessments useful tools estimate LV pressure, atrio-ventricular coupling relaxation but need be enriched evaluation terms morphology function. An integrated should also applied high arrhythmic risk, whom eccentric higher stiffness associated greater AF risk. CONCLUSION Evaluation volume, structure mandatory management AF. A could provide additional information, identifying subjects more severe remodelling. Left assessment deserves accurate study inside imaging optimised established cut-offs better recognised multicenter studies.
