糖尿病網膜症と夜間睡眠時心拍数の関連性について

Relationship between nocturnal heart beat and diabetic retinopathy

要約　目的：糖尿病網膜症が夜間安静時心拍と睡眠時心拍に及ぼす影響の報告。対象と方法：手術のために入院した219例を対象とした。男性126例，女性93例で，全員に2型糖尿病があった。糖尿病網膜症は68例が非増殖型，151例が増殖型で，平均年齢は前者が66歳，後者が60歳である。高血圧は前者の56％，後者の67％にあった。パルスオキシメータで夜間安静時と睡眠時の心拍数を測定した。結果：夜間安静時と睡眠時の心拍数は，ともに増殖糖尿病網膜症で高値であった。低年齢と睡眠時心拍数が高値であることが，その関連因子であった。結論：夜間安静時と睡眠時の心拍数が高い糖尿病患者は，増殖糖尿病網膜症に進行する可能性がある。

Abstract.　Purpose：To report nocturnal heart rate in patients with nonproliferative or proliferative diabetic retinopathy. Cases and Method：This study was made on 219 hospitalized patients. The series comprised 126 males and 93 females. All had type Ⅱ diabetes mellitus. Nonproliferative retinopathy was present in 68 cases and proliferative in 151. The age averaged 66 years in the former group and 60 in the latter. Systemic hypertension was present in 56％ and 67％ respectively. Heart beat was measured during rest in the night and during sleep using a pulse oxymeter. Results：Heart rate during rest in the night and during sleep was significantly higher in patients with proliferative than nonproliferative retinopathy. Young age and high heart rate during sleep were identified as factors related to above findings. Conclusion：High heart rate in diabetic persons may be a predictor of proliferative diabetic retinopathy.
