ALB and Hypokalemia: In comparison to the EH group, the PA group had older age, higher rate of uncontrolled hypertension (systolic blood pressure ≥ 140 mmHg and/or diastolic blood pressure ≥ 90 mmHg despite treatment with antihypertensives), higher rate of hypokalemia (serum potassium <3.5 mmol/L), higher rate of elevated urinary albumin/creatinine ratio (≥ 30 mg/g), and higher rate of ventricular septal hypertrophy (interventricular septal thickness at diastole ≥12 mm) (all P < .05).
