Spontaneous intracerebral hemorrhage (ICH) is the most morbid of all stroke types with a high early mortality and significant early disability burden. Traditionally, outcome assessments after ICH have mirrored those of acute ischemic stroke, with 3 months post-ICH being considered a standard time point in most clinical trials, observational studies, and clinical practice. At this time point, the majority of ICH survivors remain with moderate to severe functional disability. However, emerging data suggest that recovery after ICH occurs over a more protracted course and requires longer periods of follow-up, with more than 40% of ICH survivors with initial severe disability improving to partial or complete functional independence over 1 year. Multiple other domains of recovery impact ICH survivors including cognition, mood, and health-related quality of life, all of which remain under studied in ICH. To further complicate the picture, the most important driver of mortality after ICH is early withdrawal of life-sustaining therapies, before initiation of treatment and evaluating effects of prolonged supportive care, influenced by early pessimistic prognostication based on baseline severity factors and prognostication biases. Thus, our understanding of the true natural history of ICH recovery remains limited. This review summarizes the existing literature on outcome trajectories in functional and nonfunctional domains, describes limitations in current prognostication practices, and highlights areas of uncertainty that warrant further research.
自发性脑出血 (ICH) 是所有中风类型中最致命的一种,具有较高的早期死亡率和显著的早期残疾负担。传统上,ICH 后的预后评估与急性缺血性中风相似,大多数临床试验、观察性研究和临床实践都将 ICH 后 3 个月作为标准时间点。此时,大多数 ICH 幸存者仍存在中重度功能残疾。然而,新出现的数据表明,ICH 后的恢复过程更为漫长,需要更长的随访时间,超过 40%的初始严重残疾的 ICH 幸存者在 1 年内可改善至部分或完全功能独立。其他多个恢复领域也影响着 ICH 幸存者,包括认知、情绪和健康相关生活质量,ICH 对这些领域的研究仍不够深入。更为复杂的是,ICH 后死亡的最重要驱动因素是在开始治疗和评估延长支持性护理的效果之前,就过早地停止维持生命的治疗,这受到基于基线严重程度因素和预后偏差的早期悲观预后的影响。因此,我们对 ICH 恢复的真实自然史的理解仍然有限。本综述总结了功能和非功能领域结局轨迹的现有文献,描述了当前预后实践的局限性,并强调了需要进一步研究的不确定领域。
