Description
Tetsuro Maeda leads a seven-author pilot letter in 2026 on whether insomnia, sleep apnea, or both at once worsen blood vessel function in people with COPD. Damaged vessel lining drives cardiovascular disease in COPD, and each sleep disorder alone is linked to vessel harm. The single-center study drew 24 people from a research registry.
Each person filled in sleep questionnaires and had fingertip temperature checks that yield a vessel reactivity index. Half the group scored in the low reactivity range. Worse insomnia severity and poorer sleep quality tracked with lower vessel reactivity, and insomnia past the clinical cutoff linked to a drop of about 0.94 index units. Apnea risk scores showed no such link. Maeda's team presents the pilot as early work.
