Key result
Sleep disorders are linked to reduced HRV and increased risk of arrhythmias and cardiovascular events.
Why the study?
Sleep plays a fundamental role in cardiovascular autonomic regulation, and heart rate variability (HRV) can be negatively influenced by sleep disorders.
Do sleep disorders reduce heart rate variability and increase cardiovascular risk?
Population
42 studies published between 2013 and 2024 correlating sleep, HRV, and cardiovascular outcomes

Supports integrating sleep assessment with HRV monitoring for arrhythmia risk stratification; extends observational links to guide future interventional trials.
Systematic Review (n=42)
Do sleep disorders reduce heart rate variability and increase cardiovascular risk?
Joint assessment of sleep and HRV can contribute to early risk stratification and the formulation of more effective preventive strategies.
Bueno et al. (2025) conducted a systematic review in Sleep disorders and cardiovascular risk (n=42). Sleep disorders (poor sleep quality, obstructive sleep apnea, chronic insomnia) was evaluated on Heart rate variability and cardiovascular risk. Poor sleep quality and sleep disorders such as obstructive sleep apnea and chronic insomnia significantly reduce heart rate variability, increasing the risk of arrhythmias and cardiovascular events.
