Table 1.
Statistical differences in demographic characteristics and laboratory data in two groups of patients (values are expressed as mean ± SD).
| Parameter | PA (n = 30) | EH (n = 31) | p |
|---|---|---|---|
| Age (years) | 55 ± 11 | 54 ± 10 | NS |
| Gender (male/female) | 8/22 | 16/14 | NS |
| Body mass index (kg/m2) | 26.9 ± 4 | 25.1 ± 3 | NS |
| SBP/DBP | 135 ± 17/82 ± 10 | 129 ± 11/79 ± 6 | NS/NS |
| Heart rate (bpm) | 70 ± 10 | 70 ± 8 | NS |
| Glycemia (mg/dL) | 92 ± 13 | 94 ± 18 | NS |
| Metabolic syndrome | 11/30 | 8/31 | NS |
| Serum K+ (mEq/dL) | 3.99 ± 0.68 | 4.27 ± 0.37 | <0.05 |
| Creatinine (mg/dL) | 1 ± 0.19 | 0.86 ± 0.15 | <0.001 |
| PAC (ng/dl) | 426 ± 422 | 104 ± 60 | <0.0001 |
| PAC/PRA (ng/dl:ng/ml/h) | 84.3 ± 79 | 17.6 ± 15 | <0.00002 |
PA, primary aldosteronism; EH, essential hypertension; SBP/DBP, systolic and diastolic blood pressure; PAC, plasma aldosterone concentration; PAC/PRA, plasma aldosterone/plasma renin activity; NS, not significant; p < 0.05 is considered statistically significant.
