Recently, the team from Guangzhou Medical University published a study titled Association of Disrupted Delta Wave Activity During Sleep With Long Term Cardiovascular Disease and Mortality in the Journal of the American College of Cardiology, revealing that during sleep, δ The relationship between wave activity interruption and long-term cardiovascular disease and mortality.
The research team used two large cohorts, the Sleep Heart Health Study (SHHS) and the Male Osteoporotic Fracture Study (MrOS). The SHHS cohort participants included 1785 men and 2273 women, with an average age of 62.4 ± 11 years. 32.8% of the participants had a history of hypertension and 5.6% had diabetes; The MrOS cohort included 2193 participants, with an average age of 72.6 ± 5.4 years. 37.7% participants had a history of hypertension, and 7.8% had diabetes.
The follow-up time for the SHHS cohort was 11 ± 2.8 years, while the follow-up time for the MrOS cohort was 15.5 ± 4.4 years. The research team found through Kaplan Meier analysis that, δ Wave activity as a fundamental EEG feature of deep sleep( δ The higher the wave activity, the better the sleep quality, and there is a significant correlation with coronary heart disease, cardiovascular disease, and cardiovascular disease mortality.
