Purpose
To assess how expansion sphincter pharyngoplasty (ESP) impacts blood pressure (BP) and health-related quality of life (HRQOL) in hypertensive patients with obstructive sleep apnea (OSA).
Methods
Patients were separated into two groups based upon whether or not they adhered to antihypertensive drug regimens. Patients underwent 24-h ambulatory BP monitoring before and at 6 months post-ESP, while clinical BP measurements and HRQOL questionnaires (SF-36) were conducted over the course of 24 months post-surgery.
Results
We enrolled 62 patients, with 25 and 37 in the medicated and non-medicated groups, respectively. Mean 24-h BP differed significantly, with systolic and diastolic BP (SBP and DBP) decreases of 5.3 mmHg and 2.5 mmHg, respectively (P <0.01). Mean 24-h SBP and DBP decreases in the medicated group were 10.2 mmHg and 4.6 mmHg, respectively (P < 0.001), with significant decreases during the daytime of 8.6 mmHg, 3.0 mmHg, and nighttime of 12.3 mmHg, 7.7 mmHg (P <0.001). In the non-medicated treatment group, 24-h SBP and DBP decreases were 1.9 mmHg and 1.1 mmHg (P < 0.005) with significant decreases in mean nighttime BP values of 3.2 mmHg and 1.9 mmHg (P < 0.001). While pre- and postoperative SF-36 results differed significantly, no differences were observed between the two groups.
Conclusion
ESP decreases BP and improves HRQOL in OSA patients with hypertension, particularly in combination with antihypertensive drugs.
