Abstract

Background: Atrial fibrillation (AF) is an arrhythmia causing significant symptoms and raising the risk of complications.

Objectives: To evaluate the association of clinical, electrocardiographic, and echocardiographic parameters with prevalent atrial fibrillation or flutter (AFF) and assess the risk profile for incident AFF using the AF prediction scores CHARGE-AF and EHR in an elderly population from a developing country.

Methods: We included all participants in ELSA-Brasil aged 60 and over whose diagnosis of AFF could be defined through self-report or electrocardiogram and who had echocardiography performed at the study's baseline. For statistical analysis, results with p values < 0.05 were considered statistically significant.

Results: Among the 2,088 participants (65 ± 4.1 years; 53% women), 88 (4.2%) had AFF. Those with AFF were older and had higher rates of heart failure (HF), previous myocardial infarction, left bundle branch block (LBBB), prolonged QT interval, supraventricular extrasystoles, and sinus bradycardia. They also had larger left atrial and left ventricular dimensions, and lower left ventricular ejection fraction (LVEF). Multivariable analysis showed that HF, LBBB, larger left atrium, and lower LVEF were independently associated with AFF. The 5-year risk for incident AFF was low (< 2.5%) in 63% and high (> 5%) in 12% of individuals according to the CHARGE-AF score, and low in 67% and high in 13% according to the EHR.

Conclusion: AFF was found in 4.2% of this older Brazilian cohort. AFF was linked to HF history, LBBB, left atrial dilation, and reduced LVEF. Additionally, 12% to 13% of patients in sinus rhythm were at high risk for AFF. Monitoring clinical, electrocardiographic, and echocardiographic parameters can aid in early identification of high-risk individuals.

elsa -巴西老年人群中房颤流行的相关特征和房颤发生的风险概况
背景:心房颤动(AF)是一种引起显著症状并增加并发症风险的心律失常。目的:评估临床、心电图和超声心动图参数与房颤或扑动(AFF)的相关性,并利用AF预测评分CHARGE-AF和EHR评估发展中国家老年人房颤或扑动的风险概况。方法:我们纳入了所有年龄在60岁及以上的elsa - brazil参与者,他们的AFF诊断可以通过自我报告或心电图来确定,并且在研究基线时进行了超声心动图检查。以p值< 0.05为差异有统计学意义。结果:在2088名参与者中(65±4.1岁;AFF患者年龄较大,心力衰竭(HF)、既往心肌梗死、左束支传导阻滞(LBBB)、QT间期延长、室上性心动过速和窦性心动过缓的发生率较高。他们的左心房和左心室尺寸更大,左心室射血分数(LVEF)更低。多变量分析显示HF、LBBB、大左心房和低LVEF与AFF独立相关。根据CHARGE-AF评分,发生AFF的5年风险低(< 2.5%)的占63%,高(< 5%)的占12%,根据EHR,低(67%)和高(13%)的占13%。结论:在这个巴西老年队列中,有4.2%的人发现AFF。AFF与HF病史、LBBB、左心房扩张和LVEF降低有关。此外,12%至13%的窦性心律患者是AFF的高危人群。监测临床、心电图和超声心动图参数有助于早期识别高危人群。
