Contemporary data from population studies on the incidence and complications of venous thromboembolism (VTE) are limited. An observational cohort study was undertaken to estimate the incidence of first and recurrent VTE. The cohort was identified from all patients in the UK Clinical Practice Research Datalink (CPRD) with additional linked information on hospitalisation and cause of death. Between 2001 and 2011, patients with first VTE were identified and the subset without active cancer-related VTE observed for up to 10 years for recurrent VTE. The 10-year cumulative incidence rates (CIR) were derived with adjustment for mortality as a competing risk event. A total of 35,373 first VTE events (12,073 provoked, 16,708 unprovoked and 6592 active cancer-associated VTE) among 26.9 million person-years of observation were identified. The overall incidence rate (IR) of VTE was 131.5 (95% CI, 130.2-132.9) per 100,000 person-years and 107.0 (95% CI, 105.8-108.2) after excluding cancer-associated VTE. DVT was more common in the young and PE was more common in the elderly. VTE recurrence occurred in 3671 (CIR 25.2%). The IR for recurrence peaked in the first six months at around 11 per 100 person years. It levelled out after three years and then remained at around 2 per 100 person years from year 4-10 of follow-up. The IRs for recurrences were particularly high in young men. In conclusion, VTE is common and associated with high recurrence rates. Effort is required to prevent VTE and to reduce recurrences.
目前关于静脉血栓栓塞症(VTE)发病率和并发症的人群研究数据有限。本观察性队列研究旨在评估首次和复发性 VTE 的发病率。该队列来自英国临床实践研究数据链(CPRD)中的所有患者,并额外链接了住院和死因信息。在 2001 年至 2011 年间,确定了首次 VTE 患者,并对无活动性癌症相关 VTE 的患者进行了长达 10 年的随访,以观察复发性 VTE。采用调整死亡率作为竞争风险事件的方法计算 10 年累积发病率(CIR)。在 2690 万人年的观察期间,共发现 35373 例首次 VTE 事件(12073 例为诱因,16708 例为无诱因,6592 例为活动性癌症相关 VTE)。VTE 的总体发病率(IR)为 131.5(95%CI,130.2-132.9)/10 万人年,排除癌症相关 VTE 后为 107.0(95%CI,105.8-108.2)。DVT 在年轻人中更为常见,PE 在老年人中更为常见。VTE 复发发生在 3671 例(CIR 25.2%)。复发的 IR 在头 6 个月达到高峰,约为每 100 人年 11 例。3 年后趋于平稳,随后在随访的第 4-10 年维持在约每 100 人年 2 例。年轻人中复发的 IR 特别高。总之,VTE 很常见,且与高复发率相关。需要努力预防 VTE 和减少复发。
