Heart & Cardiology/Pulmonary hypertension
Is a RVSP of 46.26 on a Doppler considered very high? How can a CPAP for sleep apnea effect this ? What are other suggestions for this rating on a Doppler?
Hi, there is reading on heart health etc. at http://blog.myheart.net
The RVSP stands for right ventricular systolic pressure, and its a measurement derived from the echocardiogram that tries to estimate your pulmonary pressures, which are the pressures inside your arteries in your lungs. Although echo is used to screen for this, it is not the gold standard in diagnosing it. A value less than 36 is unlikely to represent PH, a value over 50 is highly likely to represent PH and the values in between may be suggestive but not confirmatory. A value of 46 is certainly not considered very high, but is higher than usual. Depending on the other findings on your echo and your symptoms then evaluation and treatment for underlying causes and if needed a right heart catheterization would be the next step to confirm the findings although that is unlikely to be required in most cases.
Sleep apnea has been associated with pulmonary hypertension, although the obesity hypoventilation syndrome variant has a stronger association. In either case cpap treatment is felt to be beneficial in this setting as it may potentially have a favorable effect on this, and also it is known to improve cardiovascular risk. Other measures such as weight loss and exercise are also important. Treatment of underlying lung disease is also important if it is present.
Hope that helps,
