Sudden Cardiac Death

Saturday, June 15, 2013

The American Academy of Cardiovascular Sleep Medicine

reported today on a long term study done by a noted electrophysiologists (heart doctors who specializes in cardiac rhythms) on the increased risk of sudden cardiac (SCD) death in people with sleep apnea. 

450,000 people die annually of sudden cardiac death (caused by a leathal heart rhythm).

The 3 major predictors of SCD are age 60 or older, moderate obstructive sleep apnea, and drops in oxygen levels.  During an apnea event the oxygen level typical drops, at times to dangerously low levels. People with a cardiac history (such as heart failure or coronary artery disease) are at the highest risk. 

Those that also have sleep apnea as well have a higher risk of SCD and worse outcomes. Anyone who suspects they have sleep apnea should see a sleep specialist.  That would include symptoms of increase daytime fatigue and sleepiness, snoring, gasping or snoring arousals, or witnessed sleep apnea.
