Objective: Hypertension is a common comorbidity in obstructive sleep apnea/hypopnea syndrome (OSAHS). OSAHS can raise blood pressures to pre-hypertensive and hypertensive ranges, increase the prevalence of "nondipping" overnight blood pressure patterns, and increase the risk of resistant hypertension. The gold standard treatment for OSAHS is non-invasive ventilation through CPAP. The aim of this study is to investigate the effects of noninvasive positive pressure ventilation/CPAP on symptoms of hypertension and the blood pressure measurements in hypertensive patients having OSAHS.
Patients and methods:We conducted a retrospective study among 10 male patients with OSAHS (group 1) and comorbid hypertension and 10 control subjects (group 2) with the same disease, the first 10 patients received non-invasive positive pressure ventilation therapy while the controls did not. The data was collected during duration of 2 months (1 month -before treatment and 1 month -after treatment. The AHI (apnea-hypopnea index)/RDI (respiratory disturbance index) and 6 times per day blood pressures measurements, keeping a close watch on general hypertension symptoms through a customised questionnaire.Results: When both the group's data were compared it showed a considerable decline in;
