摘要

The HELT-E2S2 score, replacing diabetes mellitus and heart failure and adding extreme elderly (≥ 85 years), type of atrial fibrillation (AF), and low body mass index (BMI), has been proposed as a new measure for stratifying the risk of stroke in Japanese patients with AF. However, the association of the HELT-E2S2 score with left atrial appendage (LAA) dysfunction in patients with ischemic stroke remains unclear. We performed transthoracic and transesophageal echocardiography and evaluated the HELT-E2S2 scores in 593 patients with acute ischemic stroke and 296 patients without acute ischemic stroke as the control group. LAA dysfunction, defined as the presence of an LAA thrombus and/or severe spontaneous echo contrast, was identified in 182 patients. In a receiver operating characteristic curve analysis, the area under the curve of the HELT-E2S2 score for predicting LAA dysfunction was significantly higher than those of the CHADS2 score (0.74 vs. 0.67, P < 0.001) and the CHA2DS2-VA score (0.74 vs. 0.67, P < 0.001). Multivariate logistic regression analysis showed that the HELT-E2S2 score was an independent predictor of LAA dysfunction after adjusting for conventional risk factors. The HELT-E2S2 score is a promising marker for predicting LAA dysfunction in patients with ischemic stroke.
