To measure the distribution of electrocardiographic ST segment depression, and evaluate its relationships with cardiovascular risk factors based on the cross-sectional studies within a rural Korean community.
This study analyzed 1,343 persons, over 40 years old, who participated in a baseline survey during 2002-2005; the exclusion criteria included: a past history of myocardial infarction and angina pectoris, and specific conduction abnormalities. A Standard 12 leads ECG was recorded using an FCP-2101 (Fukuda Denshi Co.). The ST segment depression was retrospectively measured by a physician, according to the Minnesota code classification.
ST segment depression was found in 3.6 and 6.4% of male and female participants, respectively. After adjusting for age, gender, smoking, physical activity and obesity differences, high blood pressure showed significant relations with ST depression in females (male ORs=2.67, 95% CI=0.85-8.50; female ORs=2.62, 95% CI=1.29-5.32)
As an ischemic ECG sign, ST depression was related to hypertension in female participants. This relationship remained significant, even after cases with left ventricular hypertrophy were removed.
基于韩国农村社区的横断面研究，测量心电图ST段压低的分布情况，并评估其与心血管危险因素的关系。
本研究分析了2002年至2005年期间参与基线调查的1343名40岁以上人群；排除标准包括：既往心肌梗死和心绞痛病史，以及特定传导异常。使用FCP - 2101（福田电子株式会社）记录标准12导联心电图。ST段压低由一名医生根据明尼苏达编码分类进行回顾性测量。
男性和女性参与者中ST段压低的发生率分别为3.6%和6.4%。在调整年龄、性别、吸烟、体力活动和肥胖差异后，高血压与女性ST段压低显著相关（男性比值比=2.67，95%置信区间=0.85 - 8.50；女性比值比=2.62，95%置信区间=1.29 - 5.32）
作为一种缺血性心电图表现，ST段压低与女性参与者的高血压有关。即使排除左心室肥厚病例后，这种关系仍然显著。
