Abstract

In the last 3 decades, the prevalence of sleep disorders and sleep complaints have been increasing, including respiratory events, difficulties in falling asleep and in the sleep maintenance, and excessive daytime sleepiness (EDS). Obstructive sleep apnea (OSA), insomnia, and EDS are risk factors of cardiovascular outcomes. Nevertheless, the effects of the association among these sleep disturbances are still divergent and the methodological limitations of the studies reduce the validity of the existing findings. Our research aims to investigate the relationship between EDS or insomnia associated with OSA in the risk of cardiovascular outcomes. This study consists in a large prospective longitudinal population-based study after 8 years of patients follow-up. To evaluate the isolated effect of EDS and when associated with OSA on the cardiovascular risk, the participants from the population-based study will be distributed in the groups no-OSA without EDS, no-OSA with EDS, OSA without EDS, and OSA with EDS. To evaluate the isolated effect of insomnia and when associated with OSA on the cardiovascular risk, the participants will be distributed in the groups no-OSA without insomnia, no-OSA with insomnia, OSA without insomnia, and OSA with insomnia. The outcomes that will be evaluate comprise the mortality rate, frequency of cardiovascular events, and the profile of cardiovascular risk factors. We expect that the findings of our study indicate that, besides the isolated effect, the OSA associated with EDS or insomnia potentiates the negative effects of OSA on patients' health. This research could provide new perspectives of diagnostic and therapeutic approaches for sleep disorders, aiming to decrease the risk of cardiovascular diseases and to improve the individuals' quality of life.
