Study Shows Obstructive Sleep Apnea Increases Risk of Sudden Cardiac Death.

 

Obstructive sleep apnea (OSA)  is a novel risk factor for sudden cardiac death (SCD), according to a study published June 11 in the Journal of the American College of Cardiology JACC.

 

The study looked at 10,701 adults referred for polysomnography (sleep study) and followed them for an average of 5.3 years for incidents of resuscitated or fatal SCD.

 

Results showed that 142 patients experienced SCD, with the most common predictors being a patient aged 60 years or above , having 20 apnea episodes an hour and having a lowest nocturnal oxygen saturation level of below 78 percent.

 Results showed that the severity of nocturnal hypoxemia strongly predicts SCD independently of other risk factors. In the lowest nocturnal oxygen saturation, a drop to below 78 percent increases a patient’s risk of SCD by 81 percent.

“People at risk for OSA ought to be screened with a sleep study, and potentially then being treated for sleep apnea might reduce the risk of dying suddenly,” says Deepak Bhatt, MD, MPH, FACC, in a CardioSource Video News interview on the study’s findings.

It is well known that sleep apnea is seen in obese individuals and can lead to high blood pressure and heart beat problems in the long run.

Prompt recognition and Early treatment of OSA in obese individuals is recommended.

Check for sleep apnea in individuals with diabetes and hypertension.

All patients with type 2 diabetes or hypertension should be evaluated for sleep apnea by a board-certified sleep medicine physician, the American Academy of Sleep Medicine (AASM) advised this week in a position statement.

“Type 2 diabetics and people with hypertension are much more likely to have obstructive sleep apnea [OSA] than other people, and as a result, should immediately discuss their risk for sleep apnea with a sleep specialist,” AASM president Dr M Safwan Badr said in statement.

 

Obstructive sleep apnea (OSA) is a sleep disorder seen in overweight and obese individuals where patients have obstruction of their upper airways during sleep leading to disruption of sleep. This disturbed sleep at night causes excessive daytime somnolence and fatigue. This disorder also causes hypertension, increase in blood sugars and increased incidence of a heart beat disorder called atrial fibrillation.

 

New research has consistently proved that sleep apnea may drive uncontrolled BP. Prompt recognition and treatment of sleep apnea improves BP control and also reduces average 24-hour blood sugar by 11 mg/dl. This also improves diabetes control and reduces the number of drugs required for BP control.

Prompt recognition of sleep apnea and its treatment will improve control of BP and diabetes!
