Why the study?
Does CPAP therapy improve blood pressure control in patients with resistant hypertension and obstructive sleep apnea?
Does CPAP therapy improve blood pressure control in patients with resistant hypertension and obstructive sleep apnea?
This review highlights the high prevalence of OSA in resistant hypertension and supports the use of CPAP and mineralocorticoid antagonists as effective add-on therapies for blood pressure control.

May guide integrated care in comorbid resistant hypertension and OSA; leaves open need for RCTs to confirm benefits.
Enhanced target organ damage and cardiovascular morbidity represent common issues observed in both resistant hypertension and obstructive sleep apnea. Common pathophysiological features and risk factors justify their coexistence, especially in individuals with increased upper-body adiposity. Impaired sodium handling, sympathetic activation, accelerated arterial stiffening, and impaired cardiorenal hemodynamics contribute to drug-resistant hypertension development in obstructive sleep apnea. Effective CPAP therapy qualifies as an effective "add-on" to the underlying antihypertensive pharmacological therapy, and emerging evidence underlines the favorable effect of mineralocorticoid antagonists on both resistant hypertension and obstructive sleep apnea treatment.
