Brief Summary

Obstructive sleep apnea syndrome (OSA) is the most frequent sleep disorder characterized by excessive decrease in muscle tone of the soft palate, the tongue and the posterior pharyngeal wall. It leads to airway collapse. In cases of decreased airway passage hypoventilation (hypopnea) occurs while periodic lack of airflow is called apnea. An obstructive sleep apnea syndrome is recognized as an independent cardiovascular risk factor. OSA is very common in patients with resistant hypertension. RAH is diagnosed when blood pressure remains elevated despite simultaneous use of 3 antihypertensive agents from different groups of drugs at optimal to maximum doses, including a diuretic. In patients with OSA frequent episodes of hypoxemia during sleep result in the repeated activation of the sympathetic nervous system. What is more, the episodes of respiratory disorders increases in levels of aldosterone serum concentration with following sodium and water retention and elevation of blood pressure finally. An increased aldosterone level also stimulates synthesis of collagen, promotes stiffening of the arterial wall, myocardial fibrosis with heart muscle remodeling and takes part in development of left ventricular hypertrophy (LVH) - common complication of hypertensive patients with OSA. Several studies, including the Sleep Heart Health Study have confirmed that severe OSA is associated with high prevalence of concentric hypertrophy through sympathetic activation and vasoconstriction. Eplerenone is a selective mineralocorticoid receptor inhibitor. It has no affinity for glucocorticoid, progesterone and androgen receptors and therefore has lower risk of side effects. Eplerenone lowers blood pressure and inhibits heart muscle fibrosis. The hypotensive effect is caused by reduction of fluid retention. Probably, in patients with OSA, a reduction of fluid accumulation especially at the level of the neck may contribute to lowering the resistance in the upper respiratory tract and in that way it may help to decrease the severity of OSA. As LVH remains a strong and independent predictor of total mortality and death from cardiovascular causes, in this study we want to assess whether the addition of Eplerenone to a standard antihypertensive therapy will favorably change left ventricular geometry. We also want to check if the addition the Eplerenone to a standard antihypertensive therapy could be an effective therapeutic option for patients with OSA and RAH.

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • confirmation of resistant hypertension(RAH). RAH was recognized when in spite of the use of at least 3 antihypertensive agents (including a diuretic) in maximum doses, it was impossible to achieve the target values of BP (\< 140/90 mmHg).
  • diagnosing of moderate or severe sleep apnea (OSA) on the basis of apnoea-hypopnea index (AHI) in polysomnography. AHI was defined by the total number of apnoea's and hypopneas per hour of sleep. The severity of OSA was determined as: mild (AHI 5-15), moderate (AHI 15 - 30) and severe (AHI ≥ 30)
  • signing informed and written consent to participation in the study.

You may not qualify if:

  • secondary hypertension (other than primary hyperaldosteronism),
  • myocardial infarction,
  • stroke within 6 months before the study,
  • congestive heart failure with New York Heart Association (NYHA) grade III-IV,
  • chronic kidney disease (GFR \< 30 ml/min),
  • active addiction to alcohol or psychoactive substances,
  • active cancer disease.
