Prevalence of masked hypertension evaluated by home blood pressure monitoring in a large sample of patients with office blood pressure <140/90 mmHg.

Aim: Patients with masked hypertension have a higher incidence of target organ damage, including increased left ventricular mass and carotid atherosclerosis and cardiovascular events when compared with normotensive patients. The adverse cardiovascular risks are even greater in patients already taking antihypertensive medication.

Objective: To identify the prevalence and clinical characteristics of masked hypertension in a large multicenter Brazilian sample that underwent office and home blood pressure monitoring.

Impact of CPAP on arterial stiffness in patients with obstructive sleep apnea: a meta-analysis of randomized trials.

Purpose: This study aimed to perform a systematic review and meta-analysis of randomized trials investigating the effect of continuous positive airway pressure (CPAP) on non-invasive markers of arterial stiffness in patients with OSA.

Methods: The purpose of the study was to evaluate the effect of CPAP on markers of arterial stiffness (pulse wave velocity (PWV) and augmentation index (Aix)) in patients with OSA. The study adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

Prevalence of Obstructive Sleep Apnea and Obesity Among Middle-Aged Women: Implications for Exercise Capacity.

Study Objectives: The aim of the current study was to evaluate the association between obstructive sleep apnea (OSA) and exercise capacity in middle-aged women.

Methods: Consecutive middle-aged female subjects without cardiovascular disease, aged 45 to 65 years, from two gynecological clinics underwent detailed clinical evaluation, portable sleep study, and treadmill exercise test.

Results: We studied 232 women (age: 55.
