New data shows resistant hypertension conferred increased risk for sleep apnea and having both conditions increased risk for ischemic events and heart failure, according to Healio.

Researchers conducted a retrospective cohort study between 2006 and 2010 of 470,386 adults with hypertension from the Kaiser Permanente Southern California database.

Participants were stratified by whether they had resistant or nonresistant hypertension, and ORs for sleep apnea were calculated for both groups.

The researchers also performed analyses adjusted for age, sex, race, BMI, chronic kidney disease and other comorbidities to determine HRs for ischemic heart events, congestive HF, stroke and mortality among those with sleep apnea.
