Aims and objectives: The present study investigated whether morning or afternoon activity is more effective at increasing the high-frequency (HF) index, a parasympathetic index, in patients with cardiovascular risk factors. Background: A decreased HF index, a heart rate variability (HRV) parameter, is a well-established marker of poor cardiovascular prognosis. Because blood pressure and sympathetic tone are higher in the morning, physical activity and exercise in the afternoon has been recommended for patients with cardiovascular diseases. However, there have been no reports concerning the superior effects of afternoon exercise on parasympathetic activity and sleep. Design: This observational study was a post hoc comparison. Methods: Patients’ physical activity was measured for 1 month to determine their habits. Patients’ HF index was measured by 24-h Holter electrocardiography. The study enrolled 56 patients. Each patient’s morning step count (before lunch) and afternoon step count (between lunch and dinner) were compared. We adhered to the STROBE guidelines in the present study. Results: Thirty-one patients took more steps in the morning, and 25 patients took more steps in the afternoon. The present study showed that those who took more steps in the afternoon had a significantly higher HF index during the first hour after sleep onset and during sleep than those who took more steps in the morning (p =.003,.047). Conclusions: The present study showed that those who took more steps in the afternoon had a significantly higher HF index during the first hour after sleep onset and a higher HF index during sleep than those who took more steps in the morning. Relevance to clinical practice: Exercise in the afternoon may improve the prognosis in patients with cardiovascular disease by not only preventing excessive blood pressure, afterload, and sympathetic tone but also positively influencing the parasympathetic system and sleep.

The present study compares health-related QOL between patients who practiced self-care activities comprising exercise and diet at home for at least 6 months (SA group; n = 84) after elective PCI and those who did not (NA group; n = 54). Health-related (HR) QOL was measured using the SF-36 questionnaire. Scores for two mental and three physical parameters of the HRQOL were increased in the SA, but not in the NA group. These findings indicated that the QOL was far superior among patients who exercised and consumed an appropriate diet at home for at least 6 months after elective PCI compared with those who did not.

生活習慣改善の指導には,対象者の行動変容ステージ(ステージ)に応じた支援が必要と考えられている。しかしながら実際の多くの病棟では,急性心筋梗塞(AMI)患者への退院指導方法をマニュアル化し,ステージの関心期あるいは準備期にあるAMI患者に対して同様に実施していることが多い。このような指導方法では,退院後にステージの実行期への行動変容に有効性が低いのか,病棟の勤務を評価する上で明らかにする必要があると考えられる。本研究では,退院後の軽度な運動の実施(運動習慣)への行動変容に関して,AMI患者の退院時のステージ(関心期と準備期)により,退院後6ヵ月時の実行期への行動変容(運動習慣の実施)に違いがあるのかを比較した。退院後6ヵ月時の運動者数は,関心期群4名(23.5%),準備期群7名(43.8%)で,2群間に有意な差はなかった。本研究対象のAMI患者は退院時のステージが関心期と準備期の2群間に有意な差はないことより退院時の行動変容ステージに応じて指導を変えなくても,一定の行動変容達成が得られる可能性が示唆された。しかしながら,有意差はないが関心期群が準備期群に比べ行動変容率が低い結果であり,現在の指導方法は準備期群に効果的であるとも考えられた。(著者抄録)
