New findings demonstrate that when assessing a person's cardiovascular risk, it is crucial to adopt a holistic perspective of sleep health that takes into account sleep practises as well as sleep disorders.
A major step in lowering the worldwide burden of cardiovascular disease, the leading cause of death, and lowering health disparities linked to it is the recognition that sleep is an essential component of heart health. An enhanced cardiovascular health score that counts sleep as an additional parameter was examined in relation to the risk of cardiovascular disease by researchers at Columbia University's Mailman School of Public Health. The Multi-Ethnic Study of Atherosclerosis (MESA), an ongoing study of cardiovascular disease and its risk factors in the United States, provided the study sample with information on 2000 middle-aged to older persons who participated in a sleep test and provided detailed information on their sleep habits. This is the first study to demonstrate the independent prognostic usefulness of sleep measurements for cardiovascular disease events above and above the initial seven cardiovascular health parameters.
Importantly, cardiovascular health ratings that just considered sleep time as a representation of general sleep health as well as scores that took into account several aspects of sleep health. Ideal sleep health was defined as sleeping 7 hours or more, however, no more than 9 hours, every night. The findings show that sleep is a crucial aspect of cardiovascular health. Even a cardiovascular health score is able to predict the occurrence of cardiovascular disease in the study. On the whole, the study found that 63 percent of participants slept for less than 7 hours per night and 30 percent for less than 6 hours, while 39 percent and 25 percent, respectively, had high nightly variability in sleep duration and sleep timing. Furthermore, 14 percent and 36 percent of participants reported having excessive daytime sleepiness and high levels of insomnia symptoms, and 47 percent had moderate-to-severe sleep apnea. It results in restless breathing when sleep.
Moreover, as per this study, people with short sleep durations were more likely to have irregular sleep patterns, low sleep efficiency, excessive daytime sleepiness, and sleep apnea which is future indicator of cardiovascular disease.
