Severe OSA And Hypertension


#1

I was diagnosed with essential hypertension in 1983 and prescribed hypertensive medication which controlled the elevated blood pressure.
In 2006 I was diagnosed as having severalenough obstructive sleep apnea and prescribed a CPAP that I have used every night since.
I have developed renal insufficiency and heart problems over the years and have been seeing a cardiologist over the past 4 years or so and in 216 I was taken off all hypertensive medications because my blood pressure was normal!
The cardiologist when asked why, told me that as people get older their system changes. However, I have been reading medical studies and see that the use of a CPAP actually reduces or eliminates hypertension.
Has anyone here had a similar experience of having had high blood pressure and after using the CPAP their blood pressure is normal? I am feeling that the hypertension was not the culprit-I actually had OSA.

My BP WAS EXTREMELY HIGH BEFORE THE USE OF A CPAP; NOW IT IS NORMAL. RW

It sounds like you were incorrectly diagnosed as well. There is a link between hypertension (HTN) and Sleep Apnea (OSA) and conversely, there is a link between OSA and HTN.
About one half of patients who have essential hypertension have obstructive sleep apnea, and about one half of patients who have obstructive sleep apnea have essential hypertension. A growing body of evidence suggests that obstructive sleep apnea is a major contributing factor in the development of essential hypertension. Despite many patients with obstructive sleep apnea having clear symptoms of the disorder, an estimated 80 to 90 percent of cases are undiagnosed. When physicians routinely seek the diagnosis of obstructive sleep apnea by asking patients (especially those with hypertension) three basic sleep-related questions about snoring, http://www.aafp.org/afp/2002/0115/p229.htmlexcessive daytime sleepiness and reports of witnessed apneic events, the number of cases diagnosed and treated increases by about eightfold. Eliminating snoring and occurrences of apneic-hypopneic episodes will dramatically improve patients’ quality of sleep and eliminate excessive daytime sleepiness, which has a detrimental effect on general functioning. Increased alertness will reduce the likelihood that patients will be involved in motor vehicle crashes. In most studies in which blood pressure was measured following treatment for obstructive sleep apnea, daytime and nighttime blood pressure levels were found to decrease significantly. This decrease in blood pressure may also reduce the likelihood of cardiovascular complications. The key to the diagnosis of obstructive sleep apnea is physician knowledge about the disorder. The dramatic improvement in quality of life that occurs when patients are successfully treated for obstructive sleep apnea makes detecting and treating this disorder imperative.
