There is paucity of data on the long-term outcomes after acute ischemic posterior circulation stroke (PCS). Additionally, the long-term prognostic value of the New England Medical Center-Posterior Circulation Registry (NEMC-PCR) classification of PCS has not been studied.
All consecutive patients with PCS registered in the Athens Stroke Registry between 01/1993 and 12/2012 were prospectively followed for up to 10 years and included in the analysis. The NEMC-PCR criteria were applied to classify them in relation to topography. The main studied outcomes were all cause mortality, stroke recurrence and major adverse cardiovascular events (MACEs).
A total of 653 patients with PCS (455 men, mean age 68.06 years) were followed up for 52.8 ± 44.0 months. Seventy-four (11.3%), 219 (33.5%), 335 (51.3%), and 25 (3.8%) patients had proximal, middle, distal, and multiple territories PCS, respectively. During the 10-year follow-up period, 217 patients died (7.6 per 100 patient years), 127 developed recurrent stroke (4.2 per 100 patient years), and 209 had a MACE (7.3 per 100 patient years). The cumulative 10-year mortality was higher in distal and multiple territories PCS compared to middle and proximal PCS (55.6%, 58.8%, 40.0%, 35.5%, respectively, < 0.001 by log-rank test). Patients with distal location PCS had almost twofold increased 10-year risk of mortality compared to proximal location patients after adjusting for all confounding variables (HR 1.99, 95% CI 1.05-3.77). Per TOAST classification, large artery atherosclerosis was associated with almost two-fold increase in risk of mortality, stroke recurrence and MACEs.
A large proportion of PCS patients experienced 10-year death, stroke and MACE occurrence after PCS. NEMC-PCR topographic classification was found to have significant prognostic value, with distal and middle PCS having worse long-term outcomes than proximal PCS.
关于急性缺血性后循环卒中（PCS）的长期预后数据较少。此外，新英格兰医学中心后循环登记处（NEMC-PCR）对PCS的分类的长期预后价值尚未得到研究。
对1993年1月至2012年12月期间在雅典卒中登记处登记的所有连续性PCS患者进行了前瞻性随访，最长随访10年，并纳入分析。应用NEMC-PCR标准根据病变部位对患者进行分类。主要研究结局为全因死亡率、卒中复发和主要不良心血管事件（MACE）。
共纳入653例PCS患者（455例男性，平均年龄68.06岁），随访时间为52.8±44.0个月。分别有74例（11.3%）、219例（33.5%）、335例（51.3%）和25例（3.8%）患者的病变位于近端、中段、远端和多个部位。在10年随访期内，217例患者死亡（每100患者年7.6例），127例发生复发性卒中（每100患者年4.2例），209例发生MACE（每100患者年7.3例）。与中段和近端PCS相比，远端和多部位PCS的累积10年死亡率更高（分别为55.6%、58.8%、40.0%、35.5%，对数秩检验P<0.001）。在调整所有混杂变量后，远端病变的PCS患者10年死亡风险比近端患者增加近两倍（HR 1.99，95%CI 1.05-3.77）。根据TOAST分类，大动脉粥样硬化与死亡、卒中复发和MACE风险增加近两倍相关。
很大一部分PCS患者在发病后10年出现死亡、卒中和MACE。结果发现，NEMC-PCR部位分类具有重要的预后价值，远端和中段PCS的长期预后比近端PCS更差。
