背景西班牙裔美国人心电图（ECG）异常的患病率和预后价值尚未与其他种族的大规模人群进行比较。尽管更糟糕的心血管疾病的风险概况，心血管疾病的患病率是较低的西班牙裔相比non-Hispanics.Hypothesis：我们假设，心电图异常是不太常见的西班牙裔，并没有强烈相关的心血管mortals.Methods：4.5563心电图下令为常见的临床指征在退伍军人医院进行分析。排除了1，392名在ECG检查后一周内死亡的患者。记录人口统计学特征和人口。使用加州死亡指数对患者进行了平均7.5年的随访。使用GE/马奎特计算机化ECG系统记录和分析基线ECG特征的存在。年龄，性别和心率调整后的考克斯hazardratio analysis.Results：西班牙裔与较低的心血管疾病死亡率相关，风险比（HR）为0.76（95%CI 0.65-0.89）。西班牙裔美国人中房颤、Q波、左心室肥大（LVH）、主动脉瓣置换术（aVR）中直立T波和心肌梗死损伤评分> 6等发现的发生率明显低于非西班牙裔美国人。这些发现与两组心血管死亡率增加相似，HR约为2。结论：与冠心病、房颤和左心室肥大相关的心电图特征患病率较低支持了之前的观察结果，即心血管疾病在西班牙裔人群中不太普遍。然而，与非西班牙裔相比，这些发现与死亡率增加类似。
Background The prevalence and prognostic values of electrocardiogram (ECG) abnormalities in Hispanics have not been compared to other ethnicities in a large population. Despite a worse cardiovascular risk profile, the prevalence of cardiovascular disease is lower in Hispanics compared to non-Hispanics.Hypothesis: We hypothesized that ECG abnormalities were less common in Hispanics and were not as strongly associated with cardiovascular mortality.Methods: 4.5,563 ECGs ordered for usual clinical indications in a Veteran's hospital were available for analysis. 1,392 patients who died within one week of the ECG were excluded. Demographic characteristics were recorded and the population. was followed for an average of 7.5 years using the California Death Index. The presence of baseline ECG characteristics were recorded and analyzed using the GE/Marquette computerized ECG system. Age, sex and heart rate adjusted Cox hazard ratio analyses were performed.Results: Being Hispanic was associated with lower cardiovascular death, with a hazard ratio (HR) of 0.76 (95% CI 0.65-0.89). Findings Such as atrial fibrillation, presence of Q-waves, left ventricular hypertrophy (LVH), upright T-waves in aortic valve replacement (aVR) and cardiac Infarction Injury Scores > 6 were significantly less prevalent in Hispanics than in non-Hispanics. These findings were similarly associated with increased cardiovascular mortality in both groups, each with a HR of approximately 2.Conclusion: The lower prevalence of ECG characteristics associated with coronary heart disease, atrial fibrillation and left ventricular hypertrophy support prior observations that cardiovascular disease is less prevalent in the Hispanic Population. These findings, however, are similarly associated with increased mortality compared to non-Hispanics.
