Objective:To explore effects of positive attitude on psychological pressure in patients with cardiovascular disease. Methods:300 patients with cardiovascular disease were researched using Herth hope index ( HHI ) , life orientation test-revised (CLOT-R) and perceived stress scale-Chinese version (CPSS). Results:(1) The total score of HHI in the patients with cardiovas-cular disease was 29. 64±4. 54, which was in the medium level;and the score of optimism factor was 11. 96±1. 36, which was in the low level. The total score of CPSS was 25. 38±5. 26, which was close to 26 points of health risk stress. (2) The correlation analysis showed that there were negative correlationsamong hope, optimism and psychological stress (P<0. 01); and the regression analysis showed that hope could explain 24. 6% changeability of psychological pressure, and optimism could explain 35. 2% changeability. Conclusions:The positive attitude plays an important forecasting role for psychological pressure, and can reduce psychological pres-sure.%目的：：了解积极态度对心血管疾病患者心理压力的影响。方法：选取对300例心血管疾病住院患者，采用Herth希望量表(HHI)，生活定向测验-修订版(CLOT-R)以及中文版知觉心理压力量表(CPSS)对进行调查。结果：①心血管病患者HHI量表总分为(29.64±4.54)分，为中等水平，乐观因子评分为(11.96±1.36)分，处于低等水平；CPSS量表总分评分为(25.38±5.26)分，接近健康危险压力值26分；②相关分析显示，希望、乐观与心理压力呈负相关性(P<0.01)，回归分析显示，希望可解释心理压力变异性的24.6%，乐观可解释心理压力变异性的35.2%。结论：积极态度对心血管病患者心理压力具有重要的预测作用，并可降低心理压力。
