Abnormalities on the resting electrocardiogram (ECG) are predictors of mortality and cardiovascular events among asymptomatic adults. The aim of this study was to estimate the prevalence of ECG abnormalities in adults and their association with cardiovascular risk factors.
We performed a cross-sectional analysis of ECGs in adults aged 19-59 years, living in Tubarão, Santa Catarina, Brazil. Data were collected between November 2011 and July 2012. Electrocardiographic findings were classified according to the guidelines of the Brazilian Society of Cardiology on analyzing and issuing electrocardiographic reports, and were divided into major abnormalities, minor abnormalities and no changes, as in previous studies. Pearson's chi-square test and ANOVA were used to analyze the association of ECG parameters with traditional cardiovascular risk factors.
A total of 361 participants were studied. Mean age was 40.4±12.2 years; 232 (64.3%) were women. Minor abnormalities were found in 16.9% and major abnormalities in 3.3%. Among the risk factors examined, gender, smoking, alcohol consumption, systemic hypertension, diabetes, and high Framingham risk score were significantly associated with major and minor ECG changes.
The prevalence of electrocardiographic changes was 20.2% in the population surveyed, the majority being minor. Both major and minor electrocardiographic abnormalities showed significant associations with risk of coronary artery disease, and may predict cardiovascular risk in asymptomatic adults.
静息心电图（ECG）异常是无症状成年人死亡率和心血管事件的预测指标。本研究的目的是评估成年人心电图异常的患病率及其与心血管危险因素的关联。
我们对居住在巴西圣卡塔琳娜州图巴朗市年龄在19 - 59岁的成年人的心电图进行了横断面分析。数据收集于2011年11月至2012年7月之间。心电图结果根据巴西心脏病学会分析和出具心电图报告的指南进行分类，并像以往研究一样分为重大异常、轻微异常和无变化。采用Pearson卡方检验和方差分析来分析心电图参数与传统心血管危险因素的关联。
共研究了361名参与者。平均年龄为40.4±12.2岁；232名（64.3%）为女性。发现轻微异常的占16.9%，重大异常的占3.3%。在所检查的危险因素中，性别、吸烟、饮酒、系统性高血压、糖尿病和高弗明翰风险评分与心电图的重大和轻微变化显著相关。
在接受调查的人群中，心电图变化的患病率为20.2%，大多数为轻微变化。心电图的重大和轻微异常均与冠状动脉疾病风险显著相关，并且可能预测无症状成年人的心血管风险。
