Brief Summary:
To evaluate the effect of anti-hypertensive medication on efficiency of primary aldosteronism screening test, and to determine the appropriate diagnostic cutoff valuefor Chinese hypertension patients during antihypertensive drugs therapy.

Condition or disease Intervention/treatment
Hypertension Primary Aldosteronism Diagnostic Test: withdraw antihypertensive drugs

Detailed Description:

Aldosterone-Renin ratio (ARR)is currently the most reliable means available for screening for primary aldosterone(PA). However, some antihypertensive drugs may cause false positives and false negatives on ARR. Thus, America PA guidelines suggest that antihypertensive drugs should be withdraw or change therapy before screening.

But withdraw/changing the therapy before ARR is inconvenient for patients.

we prepare to start a prospective study through recruiting hypertension patients who needs ARR screening test, completing the ARR screening before and after withdraw/change therapy.

Estimated Enrollment : 330 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: Effect of Anti-hypertensive Medications on the Diagnostic Accuracy in Screening for Primary Aldosteronism:a Prospective Study
Actual Study Start Date : September 15, 2020
Estimated Primary Completion Date : December 31, 2021
Estimated Study Completion Date : December 31, 2021

Intervention Details:
  • Diagnostic Test: withdraw antihypertensive drugs
    patients need to withdraw of all antihypertensive drugs or change therapy to Doxazosin/Diltiazem for 2-4 weeks prior

Primary Outcome Measures :
  1. Confirmation [ Time Frame: 2 weeks ]
    Consistent diagnosis after drug withdrawal

  2. Missing Diagnosis [ Time Frame: 2 weeks ]
    essential hypertension turn to fit primary aldosteronism diagnosis after drug withdrawal

  3. Misdiagnosis [ Time Frame: 2 weeks ]
    primary aldosteronism turn to fit essential hypertension diagnosis after drug withdrawal.
