Sleep Apnea and Coronary Artery Disease

Obstructive Sleep Apnea

Obstructive sleep apnea (OSA) is a sleep disorder defined as the unconscious stoppage of breathing for short periods of time throughout a night’s sleep. With OSA, there is a soft tissue obstruction of the upper airway, which impedes or completely blocks off the airway.

A study presented at the National Lipid Association Scientific Sessions evaluated 928 patients at sleep clinics, with a median follow-up of 9 months. The study was testing for the occurrence of Obstructive Sleep Apnea (OSA) from a collection of patients having a range of sleep problems. Overall, 80.1% of patients had obstructive sleep apnea and of those with sleep apnea 10% also were diagnosed with Coronary Artery Disease (CAD).

Coronary artery disease is the blockage or narrowing of the coronary arteries. Atherosclerosis is the buildup of cholesterol and fatty deposits on the inner walls of the arteries. This is also referred to as “hardening” or “clogging” of the arteries with plaques.  These plaques can restrict blood flow to the heart muscle by physically occluding the artery or by causing abnormal artery function or tone.

Without proper blood flow, the hearts become starved for oxygen and vital nutrients. This causes a painful condition known as angina. If blood supply is cut off to a section of the heart muscle completely, of if the energy consumption of the heart is greater than the blood supply a heart attack may occur.

Hypertension and Sleep Apnea

 

You have probably figured out how dangerous of a combination Coronary Artery Disease and Obstructive Sleep Apnea. In review, OSA limits the amount of oxygen from getting into your lungs to be carried to the heart. CAD is the restriction of blood flow moving through the arteries delivering oxygen throughout the body. Oxygen is vital for cellular activity that keeps our heart beating, brain thinking, and organs working. Severe lack of oxygen created from the two conditions put you are at much higher risk for health severe complications such as: Heart Disease, Hypertension, Heart Attack and Stroke.
