目的：调查经皮冠状动脉介入治疗(PCI)患者术后6个月内压力知觉与术后生活质量的相关性。方法：以2022年1月至7月某三甲医院心血管病区中的339例首次行PCI的冠心病患者为研究对象，收集患者的一般资料，并在基线期、术后3个月、6个月时评估压力知觉量表(CPSS)，西雅图心绞痛量表(SAQ)、欧洲五维健康量表(EQ-5D-5L)。通过重复测量方差分析及相关性分析压力知觉及其变化与患者生活质量的关系。结果：PCI患者在基线期、术后3个月及6个月的生活质量各维度得分之间有显著性差异，且高低压力知觉组患者SAQ量表的活动受限程度、心绞痛发作情况、治疗满意程度、疾病认知程度维度以及EQ-VAS维度得分差异均具有统计学意义(P＜0.05)；基线期、术后3个月、6个月的CPSS得分与EQ-5D-5L评分均呈负相关。结论：PCI术后患者的生活质量呈整体上升的趋势，压力知觉与生活质量存在负相关关系。
