Sleep apnea: Daytime sleepiness might help predict cardiovascular risk
A recent study categorizing people with obstructive sleep apnea based on their differing symptoms found a strong link between excessive daytime sleepiness and cardiovascular disease. OSA increases hypertension risk. Obstructive sleep apnea (OSA) causes sporadic airflow blockages during sleep. All of the different types of sleep apnea, OSA is the…
A good night's sleep could lower cardiovascular risk
Can the duration and quality of your sleep affect your cardiovascular health? A new study suggests there is a connection between how much sleep you get each night — and how well you sleep — and the risk of cardiovascular problems. Are you getting enough sleep, and could this be…
Restless legs syndrome may raise cardiovascular death risk
A new study, published in the journal Neurology, shows that the sleep and sensorimotor disorder called restless legs syndrome may raise the risk of heart-related death, particularly among older women. RLS could endanger women’s cardiovascular health. Restless legs syndrome (RLS), which is “a sleep and a neurological sensory disorder,” affects…
Sleep apnea treatment improves wellbeing, no cardiovascular benefit
The largest sleep study ever undertaken has found that the leading therapy for obstructive sleep apnea (OSA), Continuous Positive Airway Pressure (CPAP), does not reduce recurrent strokes and heart attacks in people with cardiovascular disease but does significantly improve their quality of life and mood. Researchers…
SAVE – Sleep apnea treatment: No cardiovascular benefit
More than 3 years of nightly treatment with a continuous positive airway pressure (CPAP) machine did not reduce cardiovascular risk more than usual care among patients with cardiovascular disease and obstructive sleep apnea (OSA). Findings from the Sleep Apnea Cardiovascular Endpoints (SAVE) study were presented at ESC…
Videogame addiction: Sleep loss, obesity, and cardiovascular risk for some gamers
Some children and youth with high videogame addiction tendencies may be at risk of sleep deprivation and disorders associated with obesity and poor cardio-metabolic health, Hamilton researchers have found. The study, published in the scientific journal PLOS ONE, examines the growing global gaming phenomenon and its impact on youth…
Circadian misalignment helps explain higher risk for cardiovascular disease
New research from Brigham and Women’s Hospital finds that circadian misalignment increases blood pressure and inflammatory markers. Shift workers frequently undergo circadian misalignment, disruption of the “body clock,” caused by inverted wake and sleep cycles. Although shift work, which requires workers to be awake when the brain’s circadian…
