To demonstrate the prevalence and patterns of ST elevation (STE) in ambulatory individuals and athletes and compare the clinical outcomes.
Retrospective cohort study. ST elevation was measured by computer algorithm and defined as ≥0.1 mV at the end of the QRS complex. Elevation was confirmed, and J waves and slurring were coded visually.
Veterans Affairs Palo Alto Health Care System and Stanford University varsity athlete screening evaluation.
Overall, 45 829 electrocardiograms (ECGs) were obtained from the clinical patient cohort and 658 ECGs from athletes. We excluded inpatients and those with ECG abnormalities, leaving 20 901 outpatients and 641 athletes.
Electrocardiogram evaluation and follow-up for vital status.
All-cause and cardiovascular mortality and cardiac events.
ST elevation in the anterior and lateral leads was more prevalent in men and in African Americans and inversely related to age and resting heart rate. Athletes had a higher prevalence of early repolarization even when matched for age and gender with nonathletes. ST elevation greater than 0.2 mV (2 mm) was very unusual. ST elevation was not associated with cardiac death in the clinical population or with cardiac events or abnormal test results in the athletes.
Early repolarization is not associated with cardiac death and has patterns that help distinguish it from STE associated with cardiac conditions, such as myocardial ischemia or injury, pericarditis, and the Brugada syndrome.
展示门诊患者和运动员中 ST 段抬高（STE）的发生率和模式，并比较临床结局。
回顾性队列研究。STE 通过计算机算法测量，定义为 QRS 综合波终点的≥0.1 mV。抬高通过视觉确认，并对 J 波和模糊进行编码。
退伍军人事务部帕洛阿尔托医疗保健系统和斯坦福大学大学运动员筛查评估。
总体上，从临床患者队列中获得了 45829 份心电图（ECG），从运动员中获得了 658 份 ECG。我们排除了住院患者和有心电图异常的患者，留下 20901 名门诊患者和 641 名运动员。
心电图评估和随访生命状态。
全因和心血管死亡率以及心脏事件。
前导和侧导中的 STE 在男性和非裔美国人中更为常见，且与年龄和静息心率呈负相关。即使与非运动员的年龄和性别相匹配，运动员的早期复极也更为常见。ST 段抬高大于 0.2 mV（2 mm）非常罕见。在临床人群中，ST 段抬高与心脏死亡无关，在运动员中也与心脏事件或异常测试结果无关。
早期复极与心脏死亡无关，其模式有助于将其与与心脏状况相关的 STE（如心肌缺血或损伤、心包炎和 Brugada 综合征）区分开来。
