Nasal obstruction tied to resistant hypertension in patients with uncontrolled hypertension and OSA

The authors reported the following findings:

• After five month's follow-up, 217 participants were included in the final data analysis.
• Ninety-five patients had nocturnal nasal obstruction with a more significant proportion of RH (36.8% vs 17.2%) than those without nocturnal nasal obstruction.
• Following adjustments for OS severity, demographic characteristics and sleep-related symptoms, multinomial logistic regression models revealed that nocturnal nasal obstruction (all ORs > 2.5) or NOSE ≥ 8 (all ORs > 4.5) was independently associated with higher odds of RH.
• Nasal obstruction treatment improved the NOSE score significantly but did not considerably reduce RH incidence.
• Effective nasal obstruction treatment was linked with antihypertensive drug reduction (OR 4.43).

"In uncontrolled hypertensive patients with OSA, nasal obstruction seemed to be an independent predictor of resistant hypertension," the authors wrote."

"In addition to OSA treatment, assessment and treatment of nasal obstruction should be considered in managing uncontrolled hypertensive patients with OSA."
