Ambulatory BP Monitoring Can Help ID Masked Hypertension
African Americans with masked hypertension had 2 times the risk of developing clinic hypertension.
HealthDay News — Ambulatory blood pressure monitoring could help identify undetected hypertension in at-risk populations, according to a study published online May 16 in Hypertension.
Researchers utilized ambulatory monitoring to screen 317 black patients at high risk for masked hypertension. None of the participants had diagnosed hypertension or were taking blood pressure medication when the study began.
During a median follow-up of 8.1 years, the researchers found that 187 of the participants developed clinic hypertension. Multivariable-adjusted hazard ratios of incident clinic hypertension for any masked hypertension and masked daytime, night-time, and 24-hour hypertension were 2.13, 1.79, 2.22, and 1.91, respectively.
"Our study found that African-Americans with any masked hypertension had twice the risk of developing clinic hypertension when compared to those who had both normal clinic and normal out-of-office blood pressure," study author Marwah Abdalla, MD, a cardiologist at the Columbia University Medical Center in New York City, said in an American Heart Association news release.
