UNASSIGNED: Presence and severity (grades 0-2) of AAC were measured by chest X-ray, and LVH was identified by 12-lead electrocardiogram in 27,166 Chinese aged 50+ years free of CVD from Guangzhou Biobank Cohort Study. Multivariate Cox regressions were used to examine associations of AAC and LVH with outcomes.
UNASSIGNED: During an average follow-up of 14·3 years, 5,350 deaths and 4,012 CVD occurred. Compared to those without AAC at baseline, those with AAC had higher risks of all-cause mortality (HR 1·24, 95% CI 1·17-1·31) and CVD (HR 1·22, 95% CI 1·14-1·30), with dose-response relationship (P ≤ 0·001). Furthermore, those with coexistence of AAC and LVH had higher risks of all-cause mortality (HR 1·72, 95% CI 1·37-2·15) and CVD (HR 1·80, 95% CI 1·40-2·32) than those without AAC and LVH.
UNASSIGNED: As chest X-ray has been performed commonly for health screening and in hospital patients when first admitted, AAC measured by chest X-ray can be further applied to assist cardiovascular risk stratification in the community and clinical settings.

未经评估:通过胸部X线测量AAC的存在和严重程度(0-2级),根据广州生物库队列研究,在27,166名50岁以上无心血管疾病的中国人中,通过12导联心电图确定了LVH。多变量Cox回归用于检查AAC和LVH与结果的关联。
未经评估:在平均14·3年的随访中,发生5,350例死亡和4,012例CVD。与基线时没有AAC的相比,AAC患者的全因死亡率(HR1·24,95%CI1·17-1·31)和CVD(HR1·22,95%CI1·14-1·30)风险较高,呈剂量-反应关系(P≤0·001)。此外,与没有AAC和LVH的患者相比,AAC和LVH共存的患者发生全因死亡率(HR1·72,95%CI1·37-2·15)和CVD(HR1·80,95%CI1·40-2·32)的风险更高.
未经评估:由于胸部X线检查通常用于健康筛查,并且在首次入院时也用于住院患者,通过胸部X射线测量的AAC可以进一步应用于辅助社区和临床环境中的心血管风险分层。
