Sleep Apnea Cause Pulmonary Hypertension

Sleep Apnea and Hypertension Sleep Apnea Thousand Oaks Malibu Westlake Village Ronald Popper

When a patient stops breathing, the oxygen level drops. In an effort to increase oxygen levels, blood vessels constrict, thereby increasing blood pressure and blood flow and oxygen to the brain and the heart. In addition, when a sudden arousal from sleep occurs, there is a release of adrenaline and other mediators that, over time, will narrow and stiffen blood vessels

thus leading to high blood pressure. Successfully treating obstructivesleep apnea can reverse these changes and result in lowering the blood pressure. If you suffer from high blood pressure and a sleep disorder such as Obstructive Sleep Apnea Syndrome, the two conditions may be related. Hello, I'm Ronald Popper. Thank you for watching.

Pulmonary hypertension diagnosis

So, threading a catheter directly into the heartmight be the most direct way, the gold standard, of measuringpulmonary hypertension, but there are certainlyother ways we can do it. So, if we think about the relationship of the heart and lungs inthe cardiovascular system, we have the heart here, and the lungs, the next step in where the blood is going,

so here we have our lungs. In blood, or deoxygenated blood, well, first let's draw some chambers. We have four chambers, two on top, and two on the bottom. It's from this right ventricle that we get deoxygenatedblue blood into the lungs. Remember that everything's flipped,

like the person isstanding in front of you, so this is the right,and this is the left. So, blood goes from the rightventricle into the lungs, and then back over into the left atrium. It's gonna be oxygenated red blood. So given this relationship, if we have hypertension in the lungs, that backs up into the right ventricle,

and then, not putting as muchforward into the left atrium, then, another way of evaluating the heart can tell us about pulmonary hypertension. And this is a task we call echocardiogram, usually just echo for short. So, echocardiogram. This test is basicallyputting an ultrasound probe over the heart in different directions,

and just looking at howthe chambers in a different compartment of the heart are working. So, for our purposes ofpulmonary hypertension test, the echocardiogram can showus the right ventricle. The flow going on in there,how hard it's working, will give us a clue ofpulmonary hypertension. We can also see the left atrium, see how much blood it's receiving.

So this is a very powerful diagnostic tool in pulmonary hypertension, is to look at how theheart is functioning. But an added bonus, isthat, since we can see ALL parts of the heart, we canalso see the left ventricle, and remember that, if theleft ventricle has a problem pushing blood forward,then the backup can be a cause of pulmonary hypertension.

Does Obstructive Sleep Apnea Cause Cancer Thousand Oaks Malibu Westlake Village Popper

There is no scientific evidencethat sleep apnea causes cancer. A recent article showing an “association� of sleep apnea with a higher mortality from cancer has recently raised controversy. However, when one sifts through all of the data, both supporting and conflicting, there is no clear association of sleep apnea and cancer risk.

What is known is that low levelsof oxygen associated with sleep apnea, especially severe sleep apnea, has been shown to cause anincrease in growth of blood vessels. Low oxygen levels from other causes have also been shown to do this. Therefore, it is thought that severe sleepapnea or severely depressed oxygen levels in association with other cancer risk factors “may� increase the risk of developing cancers.
