Clinical significance of left atrial geometry in dilated cardiomyopathy patients: A cardiovascular magnetic resonance study.
Ontology highlight
ABSTRACT: Background
Clinical significance of left atrial (LA) function and geometry in patients with dilated cardiomyopathy (DCM) remains uncertain.Hypothesis
LA geometric parameters assessed by cardiac magnetic resonance (CMR) predict the prognosis in patients with DCM.Methods
The present study included patients with DCM and sinus rhythm who underwent CMR between December 2007 and April 2018. LA volume was measured using CMR. LA sphericity index was computed as the ratio of the measured maximum LA volume by the volume of a sphere with maximum LA length diameter.Results
We included 255 patients in this study. During the mean follow-up of 3.92?years, hospitalization for HF occurred in 37 patients. The LA sphericity index was significantly higher in patients with hospitalization for HF than in those without (0.78?±?0.35 vs. 0.58?±?0.18, p?ConclusionLA sphericity index was an independent predictor of hospitalization for HF. Assessment of LA geometric parameters might be useful for risk stratification in patients with DCM.
