Sleep Apnoea and the Risks to Heart Health

blood pressureSnoring may be a sign of sleep apnoea and sleep apnoea needs to be treated as soon as possible. This is because this medical condition has certain effects that affect your overall health. Sleep apnoea also affects your heart in a negative way. This is why an article from talks about sleep apnoea and its heart disease risks.


High Blood Pressure (Hypertension)

Some of the largest population studies of sleep apnoea demonstrate the fact that untreated sleep apnoea increases blood pressure. People with blood pressure that is difficult to control with medications are extremely likely to have unrecognized sleep apnoea. This is called refractory essential hypertension, and it usually involves persistent blood pressure elevation despite the use of three or more medications to lower it. The good news is that the standard treatment of sleep apnoea, continuous positive airway pressure (CPAP), can be effective in lowering blood pressure.



Sleep apnoea is correlated with insulin resistance and glucose intolerance, findings that

are precursors to developing type 2 diabetes. This correlation exists independent of body mass index (BMI). This means that you can be of normal weight and sleep apnoea may still increase your risk of developing diabetes.


Coronary Artery Disease

Approximately 1 in 3 of those people with coronary artery disease have sleep apnoea, with a large fraction not complaining of excessive daytime sleepiness. The blood vessels of the heart may become narrowed by plaques, leading to chest pain or even other consequences.



Abnormal heart rhythms such as atrial fibrillation occur more frequently in those with untreated sleep apnoea. In fact, the risk of atrial fibrillation doubles with sleep apnoea,

correlating with the severity of oxygen desaturation.



Heart Failure

Studies in the U.S. and Canada suggest 47 to 61 percent of patients with heart failure have moderate to severe sleep apnoea. Mild pulmonary hypertension, a marker of heart failure, is common in sleep apnoea. It may affect up to 20% of people with OSA and occurs due to low oxygen levels leading to constriction of the blood vessels within the lungs.


Heart Attack

Studies have demonstrated the association between OSA and ischemic heart disease, including heart attacks. This is likely related, in part, to the exacerbation of the other factors described above.
