背景和目的 脑血管疾病是全世界第二大常见死因。中度和重度颈动脉狭窄导致近 10% 的中风。左心室几何形状是一些人群熟悉的预后和诊断因素；然而，关于其在颈动脉狭窄中的作用的数据尚不清楚。在我们的研究中，我们调查了左心室几何形状在预测接受颈动脉支架置入术的患者颈动脉狭窄严重程度方面的预后价值。方法对2012年1月至2016年1月在我们三级医疗中心接受颈动脉支架置入术的患者进行回顾性评估。该研究纳入了 255 名接受颈动脉支架植入术的患者。对 98 名患者的超声心动图文件进行了访问和评估。 结果 98 名颈动脉支架置入术 (CAS) 患者中，37 名 (37.7%) 检测到左心室几何形状正常，13 名 (13.2%) 患者检测到向心肥厚，9 名 (9.1%) 患者检测到偏心肥厚，39 名 (39.7%) 患者检测到向心重构。大多数情况下，正常几何形状组和偏心肥大组使用远端过滤器（82.9% vs 100%，P：0.017）。考虑到颈动脉狭窄严重程度与左心室几何形状之间的关系，我们确定向心肥厚组的狭窄严重程度在统计学上显着较高（p：0.012）。然而，虽然向心肥大组没有检测到并发症，但组间差异没有达到统计学显着性（P：0.058）。 LVMi 和如预期的那样，多普勒速度显示与狭窄严重程度显着相关（r = .23 与 .54；P：0.021，
Background and Aim Cerebrovascular diseases are the second most common cause of death worldwide. Moderate and severe carotid artery stenosis causes nearly 10% of all strokes. LV geometry is a familiar prognostic and diagnostic factor in several populations; yet, data on its role in carotid artery stenosis are unknown. In our study, we investigated the prognostic value of LV geometry in predicting carotid artery stenosis severity in patients undergoing carotid artery stenting.Methods Patients who underwent carotid artery stenting between January 2012 and January 2016 at our tertiary care center were evaluated retrospectively. Two hundred fifty-five patients who underwent carotid artery stenting were included in the study. Accessible echocardiographic documentation of ninety-eight patients was accessed and evaluated.Results LV normal geometry was detected in 37 (37.7%) of the 98 carotid artery stenting (CAS) patients, concentric hypertrophy in 13 (13.2%), eccentric hypertrophy in 9 (9.1%), and concentric remodeling in 39 (39.7%). By a majority, distal filter was used in normal geometry and eccentric hypertrophy groups (82.9% vs 100%, P: .017). Considering the relationship between carotid artery stenosis severity and LV geometry, we determined that the stenosis severity was statistically significantly higher in the concentric hypertrophy group (p:0.012). However, although no complications were detected in the concentric hypertrophy group, it did not reach statistical significance between the groups (P: .058). LVMi and as expected, Doppler velocity showed a significant correlation with stenosis severity (r = .23 vs .54; P: .021,
