Heart failure (HF) patients run four times the risk of developing cognitive impairment than does the general population, yet cognitive screening is not routinely performed.
This cross-sectional study enrolled 90 community-dwelling adults with HF aged 50 years and above. Participants took the Mini Mental Status Examination (MMSE) and Montreal Cognitive Assessment (MoCA), to measure cognitive function in persons with HF. Participants were predominately men (66%) and Caucasian (78%), aged 50-89 years (62 SD, 9 years), and 77% had an ejection fraction <40%.
Fifty-four percent of participants scored ≤26 on the MoCA, suggesting mild cognitive impairment (MCI), and 17% scored ≤22, suggesting moderate cognitive impairment, compared with 2.2% on the MMSE. The MoCA scores were lowest for visuospatial/executive domain, short-term memory, and delayed recall. These findings were similar to those in published reports.
These preliminary findings support the use of MoCA for cognitive screening in stable HF.
心力衰竭（HF）患者患认知障碍的风险比普通人群高四倍，但认知筛查并未常规进行。
本横断面研究纳入了 90 名年龄在 50 岁及以上的、居住在社区的 HF 成年患者。参与者接受了简易精神状态检查（MMSE）和蒙特利尔认知评估（MoCA），以测量 HF 患者的认知功能。参与者主要为男性（66%）和白人（78%），年龄为 50-89 岁（62 ± 9 年），77%的射血分数<40%。
54%的参与者在 MoCA 上的得分≤26，表明有轻度认知障碍（MCI），17%的得分≤22，表明有中度认知障碍，而在 MMSE 上的得分则为 2.2%。MoCA 评分最低的是视觉空间/执行域、短期记忆和延迟回忆。这些发现与已发表的报告相似。
这些初步发现支持在稳定的 HF 中使用 MoCA 进行认知筛查。
