About this trial

The goal of this observational study is to learn about the optimal dose of spironolactone treatment and the long-term outcomes on cardiovascular and cerebrovascular events in patients with lateralized PA who are unwilling to undergo surgery. The main question it aims to answer is:

1. What is the long-term effect of spironolactone treatment for lateralized PA? 2. What is the optimal dose of spironolactone treatment for the relief of renin inhibition in patients with lateralized PA? Participants will receive spironolactone treatment as part of their regular medical care for more than 12 months, and their clinical indicators, including blood pressure, biochemical remission, cardiovascular and renal damage, and the incidence of cardiovascular and cerebrovascular events, will be analyzed.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Male or female, aged 30~65 years.

PA patients with positive screening tests and saline suppression tests, and with AVS to determine lateralization. These patients have hypertension defined as office blood pressure ≥ 140/90 mmHg, or 24-hour ambulatory blood pressure showing average ≥ 130/80 mmHg, daytime blood pressure ≥ 135/85 mmHg, or nighttime blood pressure ≥ 120/70 mmHg.

Patients with unilateral aldosterone-producing adenoma who decline surgery, or patients with non-adenoma, unilateral PA confirmed by AVS and meeting the above PA-related hypertension criteria.

Provision of written informed consent to participate in the study.

Disqualifiers

Hyperkalemia.

Renal impairment or have history of renal disease: serum creatinine > 1.5 × upper limit of normal (ULN), dialysis, or nephrotic syndrome.

Other confirmed secondary hypertension: pheochromocytoma, Cushing's syndrome, thyroid disorders, parathyroid disorders, acromegaly, renovascular disease, aortic disorders, chronic alcoholism, or drug dependence, etc.

Adrenal insufficiency.

Trial outcomes

Primary outcomes

1

Change of systolic blood pressure

This study will gain insight into the effect of spironolactone treatment on systolic blood pressure. The systolic blood pressure (mmHg) is measured before and after spironolactone treatment, respectively. The changes of systolic blood pressure are analyzed after the spironolactone treatment.

Time frame
From enrollment to spironolactone treatment at 12 months.
2

Change of diastolic blood pressure

This study will gain insight into the effect of spironolactone treatment on diastolic blood pressure. The diastolic blood pressure (mmHg) is measured before and after spironolactone treatment, respectively. The changes of diastolic blood pressure are analyzed after the spironolactone treatment.

Time frame
From enrollment to spironolactone treatment at 12 months.

Secondary outcomes

1

Change of anti-hypertensive regimen

This study will gain insight into the effect of spironolactone treatment on anti-hypertensive regimen. The anti-hypertensive regimens are measured before and after spironolactone treatment, respectively. The changes of anti-hypertensive regimens are analyzed after the spironolactone treatment.

Time frame
From enrollment to spironolactone treatment at 12 months.
2

Change of serum potassium

This study will gain insight into the effect of spironolactone treatment on serum potassium. The concentrations of serum potassium (mmol/L) are measured before and after spironolactone treatment, respectively. The changes of serum potassium are analyzed after the spironolactone treatment.

Time frame
From enrollment to spironolactone treatment at 12 months.
3

Change of plasma aldosterone

This study will gain insight into the effect of spironolactone treatment on plasma aldosterone. The concentrations of plasma aldosterone (ng/dL) are measured before and after spironolactone treatment, respectively. The changes of plasma aldosterone are analyzed after the spironolactone treatment.

Time frame
From enrollment to spironolactone treatment at 12 months.
4

Change of plasma renin

This study will gain insight into the effect of spironolactone treatment on plasma renin. The concentrations of plasma renin (mU/L) are measured before and after spironolactone treatment, respectively. The changes of plasma renin are analyzed after the spironolactone treatment.

Time frame
From enrollment to spironolactone treatment at 12 months.
