Key result
The prevalence of white coat hypertension varied markedly from 12.1% to 53.2% (p<0.0001) depending on the ambulatory blood pressure standard used, impacting the associated prevalence of LVH.
Why the study?
Do different definitions of normal ambulatory blood pressure affect the diagnosed prevalence of white coat hypertension and its association with left ventricular hypertrophy in untreated hypertensive patients?
Cross-Sectional (n=393)
Do different definitions of normal ambulatory blood pressure affect the diagnosed prevalence of white coat hypertension and its association with left ventricular hypertrophy in untreated hypertensive patients?
p-value: p=<0.0001
The definition of normal ambulatory blood pressure significantly impacts the diagnosed prevalence of white coat hypertension and its correlation with target organ damage like left ventricular hypertrophy.
No takes yet. Share an insight, caveat, or question.
Different ambulatory BP thresholds markedly alter white coat hypertension prevalence and LVH associations; leaves open optimal diagnostic criteria.
Verdecchia et al. (1992) conducted a cross-sectional in Essential hypertension (n=393). Four different definitions of normal ambulatory blood pressure vs. Normotensive control subjects was evaluated on Prevalence of white coat hypertension (p=<0.0001). The prevalence of white coat hypertension varied markedly from 12.1% to 53.2% (p<0.0001) depending on the ambulatory blood pressure standard used, impacting the associated prevalence of LVH.
