The Association between a 24-Hour Blood Pressure Pattern and Circadian Change in Plasma Aldosterone Concentration for Patients with Aldosterone-Producing Adenoma

Table 2

Comparison of blood pressure measurements between patients with aldosterone-producing adenoma and essential hypertension.

	APA (n = 27)	EH (n = 27)	P value
Mean BP (mm Hg)
day time SBP	143.8 ± 13.3	137.9 ± 18.5	0.188
day time DBP	94.2 ± 10.4	89.4 ± 15.5	0.189
night time SBP	137.8 ± 15.0	130.3 ± 19.6	0.120
night time DBP	87.9 ± 11.9	83.0 ± 17.7	0.242
Day-night BP difference (mm Hg)
SBP	5.85 ± 9.40	7.63 ± 11.20	0.530
DBP	6.41 ± 6.34	6.30 ± 6.78	0.951
Relative night time decline (%)
SBP	4.01 ± 6.52	5.38 ± 7.85	0.490
DBP	6.84 ± 6.91	7.24 ± 8.21	0.845
BP pattern (dipper/nondipper)	5/22	7/20	0.513

dippers were defined as those with a >10% decline in both systolic and diastolic blood pressure
Note: day-night BP difference calculated as day time BP minus night time BP, and relative night time decline calculated as: (day time BP – night time BP) ÷ day time BP × 100%
APA, aldosterone-producing adenoma; BP, blood pressure; DBP, diastolic blood pressure; EH, essential hypertension; SBP, systolic blood pressure
