OBJECTIVE: Obstructive sleep apnea (OSA) is the most common factor involved in uncontrolled blood pressure (BP). Management of OSA is part of cardiologist work. We have few data on BP control in a population of OSA followed by cardiologists. AIM: We evaluated the prevalence of effective BP control using ambulatory measurement in a population of patients followed in cardiology. METHODS: Data from 69 OSA patients treated for more than 6 months by continuous positive airway pressure (CPAP) were collected prospectively from March 2012 until December 2012. These patients were divided into 2 groups according to the results of 24-h ambulatory BP monitoring (ABPM). Controlled BP was defined as a 24 h BP <130/80 mmHg. RESULTS: All patients were hypertensive. 44 patients (63 %) had uncontrolled hypertension (HTN). The onset of OSA (p = 0.01) and persistent daytime sleepiness appeared as predictors of uncontrolled BP. Systolic BP (SBP) during consultation and all the ABPM variables were higher in uncontrolled BP patients. Uncontrolled BP was associated with greater left ventricular mass (p = 0.02) and greater diameter of the ascending aorta (p = 0.04). CONCLUSION: Control of HTN should be evaluated in all OSA patients, using ABPM. The onset of OSA and high SBP during consultation are both factors associated with uncontrolled BP in this population. Repeating ABPM should be of interest for the follow up of these patients.
