Abstract

Background: Rheumatic heart disease (RHD) continues to be one of the leading causes of cardiovascular morbidity and mortality. The mitral valve frequently develops mitral stenosis (MS), and it is the most prevalent valve lesion in patients with chronic RHD. Left atrial (LA) functional impairment is associated with rheumatic MS.

Aim: The aim of this study was to evaluate the association between LA function and mitral valve area (MVA) in rheumatic MS patients, and to assess the echocardiographic parameters in sinus rhythm and atrial fibrillation (AF) patients.

Methods: This was a cross-sectional, descriptive study that involved patients with rheumatic MS. Patients underwent a standard 12-lead electrocardiogram and echocardiographic examination. MVA was assessed and correlated with LA function. Comparison was made between sinus rhythm and AF patients.

Results: Eighty-one patients with rheumatic MS were included in this study, with 71.6% of them having associated MR. MVA showed a statistically highly significant positive correlation with LA and right ventricular (RV) function, and a statistically significant/highly significant negative correlation with their dimensions. A higher percentage of patients with severe MS was in AF (58.1%).

Conclusions: There was a positive correlation between LA function and MVA in rheumatic MS patients. AF was related to the severity of MS.

风湿性二尖瓣狭窄患者二尖瓣面积与左心房功能之间的相关性。

背景：风湿性心脏病（RHD）仍然是心血管疾病发病率和死亡率的主要原因之一。二尖瓣经常发生二尖瓣狭窄（MS），是慢性风湿性心脏病患者最常见的瓣膜病变。目的：本研究旨在评估风湿性二尖瓣狭窄患者左心房（LA）功能和二尖瓣面积（MVA）之间的关系，并评估窦性心律和房颤（AF）患者的超声心动图参数：这是一项横断面描述性研究，涉及风湿性多发性硬化症患者。患者接受了标准的 12 导联心电图和超声心动图检查。评估了MVA并将其与LA功能相关联。对窦性心律和房颤患者进行了比较：本研究共纳入 81 例风湿性多发性硬化症患者，其中 71.6% 的患者伴有 MR。MVA与LA和右心室（RV）功能呈统计学上高度显著的正相关，而与它们的尺寸呈统计学上显著/高度显著的负相关。严重多发性硬化患者中房颤患者的比例较高（58.1%）：结论：风湿性多发性硬化症患者的 LA 功能与 MVA 呈正相关。房颤与多发性硬化症的严重程度有关。
