Key result
Mean supine blood pressure ≥130/80 mm Hg was more precise than sitting office blood pressure ≥140/90 mm Hg in diagnosing hypertension (AUC 0.820 vs. 0.550, p<0.0001).
Why the study?
Does supine blood pressure measurement accurately diagnose hypertension compared to sitting office blood pressure and ambulatory blood pressure monitoring in young and middle-aged patients?
Observational (n=280)

Absolute Event Rate: 0.82% vs 0.55%
p-value: p=<0.0001
Supine blood pressure is significantly lower than sitting blood pressure, and a threshold of ≥ 130/80 mm Hg provides a highly sensitive and specific diagnostic cut-off for hypertension.
No takes yet. Share an insight, caveat, or question.
Supine BP ≥130/80 mm Hg improves diagnostic precision; hypothesis-generating and requires prospective validation before practice change.
Krzesiński et al. (2016) conducted an observational in Arterial hypertension (n=280). Supine blood pressure measurement vs. Sitting office blood pressure measurement was evaluated on Diagnostic precision for hypertension (AUC) (p=<0.0001). Mean supine blood pressure ≥130/80 mm Hg was more precise than sitting office blood pressure ≥140/90 mm Hg in diagnosing hypertension (AUC 0.820 vs. 0.550, p<0.0001).
