| 目的 观察超声心动图用于非瓣膜病性心房颤动（NVAF）患者卒中危险分层的价值。方法 根据CHA2DS2-VASc评分将90例NVAF患者分为低危组（17例）、中危组（40例）及高危组（33例），对比其血清脑钠肽（BNP）、肌钙蛋白Ⅰ（TnⅠ）及超声参数左心房前后径（LAD）、左心房容积指数（LAVI）、二尖瓣口舒张期流速（E）、二尖瓣环舒张期运动速度（e'）和左心耳（LAA）排空速度（VLAA）、口部直径（D1）、内侧壁应变（S内）和外侧壁应变（S外）等。结果 高危组BNP明显高于中、低危组（P均<0.05），高危组TnⅠ明显高于低危组（P<0.05）。高危组LAVI明显高于中危组（P<0.05），中危组LAVI明显高于低危组（P<0.05）；高危组LAD、e'及E/e'均明显大于低危组（P均<0.05）。高危组VLAA明显低于中、低危组（P均<0.05），中危组VLAA明显低于低危组（P<0.05）；高危组D1、S内及S外均明显高于低危组（P均<0.05）。结论 超声心动图LAVI、VLAA和LAA应变等参数对于NVAF患者卒中危险分层具有一定临床应用价值。 |

| Objective To observe the value of echocardiography in stroke risk stratification of patients with non-valvular atrial fibrillation (NVAF). Methods A total of 90 NVAF patients were enrolled. Stroke risk stratification was performed according to CHA2DS2-VASc scoring system, and the patients were divided into low-risk group (n=17), medium-risk group (n=40) and high-risk group (n=33). The serum brain natriuretic peptide (BNP), cardiac troponin Ⅰ (TnⅠ) and ultrasonic parameters, including anteroposterior left atrium diameter (LAD), left atrial volume index (LAVI), mitral diastolic velocity (E), mitral valve ring diastolic velocity (e') and left atrial appendage (LAA) velocity (VLAA), orifice diameter (D1), inner wall strain (Sinner) and external wall strain (Sexternal), etc. were compared among 3 groups. Results BNP in high-risk group was significantly higher than that in medium- and low-risk groups (both P<0.05), and TnⅠ in high-risk group was significantly higher than that in low-risk group (P<0.05). LAVI in high-risk group was significantly higher than that in medium-risk group (P<0.05), and in medium-risk group was significantly higher than that in low-risk group (P<0.05). LAD, e' and E/e' in high-risk group were significantly higher than those in low risk group (all P<0.05). VLAA in high-risk group was significantly lower than that in medium-risk group (P<0.05), and in medium-risk group was significantly lower than in low-risk group (P<0.05). D1, Sinner and Sexternal in high-risk group were all significantly higher than those in low risk group (all P<0.05). Conclusion Echocardiographic parameters, such as LAVI, VLAA and strain of LAA had certain clinical application valuable for stroke risk stratification. |
