Effect of Antihypertensive Agents on Diastolic Function in Patients With Sleep Apnea
Summary
The investigators investigated diastolic function among patients with obstructive sleep apnea (OSA) and hypertension stage I. In this randomized controlled trial, participants were randomly allocated to one of two groups: chlorthalidone associated with amiloride or amlodipine. Randomization was carried out prior to the start of the trial by an epidemiologist out of clinic and the randomization list was stratified by gender and severity of OSA. The research team and participants were blinded to the randomization list and allocation concealment was implemented. This trial aimed to detect changes in the echocardiography parameters with the drug treatment (higher in the intervention than in the placebo group). The investigators also assess change in daytime sleepiness among participants who already have been diagnosed with OSA.
