Outcome Measures

Primary Outcomes (3)

  • Confirmation

    Consistent diagnosis after drug withdrawal

    2 weeks

  • Missing Diagnosis

    essential hypertension turn to fit primary aldosteronism diagnosis after drug withdrawal

    2 weeks

  • Misdiagnosis

    primary aldosteronism turn to fit essential hypertension diagnosis after drug withdrawal.

    2 weeks

Study Arms (2)

primary aldosteronism group and essential hypertensin group

patients will be diagnosed as PA or EH based on ARR and CCT off interfering meds

Diagnostic Test: withdraw antihypertensive drugs

primary aldosteronism (PA) group and essential hypertension (EH) group

The diagnosis of PA was established based on an ARR ≥20 pg·ml-1/μIU·ml-1 off interfering medications plus one of the following criteria: (1) PAC post-CCT off interfering medications was over 110pg/mL; (2) PAC post-CCT off interfering medications ranged from 80 to 110 pg/mL, but PAC post-SSIT off interfering medications exceeded 80 pg/mL. In patients with an ARR of 10-20 pg·ml-1/μIU·ml-1 but with hypokalemia or adrenal nodules, PA was also diagnosed if the confirmatory test was positive. The diagnosis of EH was determined if PA was excluded.

Diagnostic Test: withdraw antihypertensive drugs

Interventions

patients need to withdraw of all antihypertensive drugs or change therapy to Doxazosin/Diltiazem for 2-4 weeks prior

primary aldosteronism (PA) group and essential hypertension (EH) groupprimary aldosteronism group and essential hypertensin group

Study Population

Patients in the Department of Endocrinology and physical examination center of First Affiliated Hospital of CQMU who with hypertension, and under anti-hypertension medication therapy and being certificated with high risk factors of PA were recruited as the study group.

You may qualify if:

  • Persistent hypertension \>150/100mmHg, including previously diagnosed grade 2 hypertension but well controlled by 1-2 drugs; newly diagnosed hypertension with 3 days blood pressure \> 150 / 100mmHg
  • Resistant hypertension(combined with three antihypertensive drugs and one of them is diuretic but blood pressure is still greater than 140 / 90 mmHg ; or need to combined four anti-hypertensive drugs to control the blood pressure under 140 / 90 mmHg)
  • Family history of hypertension with early onset (\< 40 years old)
  • Family history of hypertension with early onset (\<40 years old) and cerebrovascular accident
  • Hypertension with spontaneous or diuretic hypokalemia
  • Hypertensive with adrenal incidentaloma
  • Hypertensive with OSAS
  • First-degree relatives of PA patients and with hypertension Stable antihypertensive medication therapy for more than 2 weeks, medication including:β-blockers, CCB, ACEi, ARB, MRA, and other diuretics.

You may not qualify if:

  • Patients hard to change or stop the medication for accomplish the screening test or diagnosis Unwilling to participate the study and refuse to sign on informed consent Patients who was diagnosed with other secondary hypertension Suspected with PA(rein concretion beyond the limit of normal reference range after stoping or changing the medication) Severe renal insufficiency (eGFR\<30 ml/min/1.73m2); pregnancy
