To compare the left atrial function utilising speckle tracking echocardiography in patients with low-risk and high-risk non-valvular atrial fibrillation.
The descriptive, cross-sectional study was conducted at the cardiology department of Kafrelsheikh University Hospital, Egypt, from January 2021 to January 2022, and comprised low-risk atrial fibrillatin participants in group I, high-risk atrial fibrillatin patients in group II, and healthy controls in group III. After detailed medical history, the subjects underwent 12-lead electrocardigram, and echocardiographic assessment, including two dimensional, M-mode, tissue doppler, and speckle tracking of the left atrium. The association of left atrial strain with Congestive heart failure, hypertension, age ≥75 (doubled), diabetes,stroke (doubled), vascular disease sex category (female)score was explored. Data was analysed using SPSS 28.
Of the 90 subjects, there were 30(33.3%) in each of the 3 groups. The mean age among the groups was significantly different among the groups (p=0.014). Left atrial ejection fraction and left atrial strain had an overall significant difference among the groups(p<0.001). Congestive heart failure, hypertension, age ≥75 (doubled), diabetes, stroke (doubled), vascular disease sex category (female)score was negatively correlated with Left atrial ejection fraction and (p<0.001) and left atrial strain (p<0.001).
In individuals with atrial fibrillatin, there was a significant decrease in left atrial strain and left atrial function. The use of speckle tracking echocardiography allowed for a more detailed analysis of left atrial mechanics. The correlation of left atrialstrain and left atrial ejection fraction with Congestive heart failure, hypertension, age ≥75 (doubled), diabetes, stroke (doubled), vascular disease sex category (female) score was significantly negative.
利用斑点追踪超声心动图比较低危和高危非瓣膜性心房颤动患者的左心房功能。
本研究为描述性、横断面研究，于 2021 年 1 月至 2022 年 1 月在埃及卡夫拉谢赫大学医院心内科进行，参与者分为低危心房颤动组（I 组）、高危心房颤动组（II 组）和健康对照组（III 组）。详细询问病史后，所有受试者均接受 12 导联心电图和超声心动图评估，包括二维、M 型、组织多普勒和左心房斑点追踪。探讨左心房应变与充血性心力衰竭、高血压、年龄≥75 岁（加倍）、糖尿病、中风（加倍）、血管疾病性别（女性）评分的相关性。使用 SPSS 28 进行数据分析。
90 例受试者中，每组 30 例（33.3%）。组间平均年龄差异有统计学意义（p=0.014）。组间左心房射血分数和左心房应变差异均有统计学意义（p<0.001）。充血性心力衰竭、高血压、年龄≥75 岁（加倍）、糖尿病、中风（加倍）、血管疾病性别（女性）评分与左心房射血分数（p<0.001）和左心房应变（p<0.001）呈负相关。
心房颤动患者左心房应变和左心房功能明显下降。斑点追踪超声心动图的应用可对左心房力学进行更详细的分析。左心房应变和左心房射血分数与充血性心力衰竭、高血压、年龄≥75 岁（加倍）、糖尿病、中风（加倍）、血管疾病性别（女性）评分呈显著负相关。
