Primary aldosteronism (PA) is a common cause of secondary high blood pressure, but its best diagnosis and treatment methods are still difficult to establish. This research thoroughly evaluates adrenal venous sampling (AVS), focusing on important clinical, technical, and methodological questions. The goal is to understand how AVS-guided care affects long-term health and biochemical results to improve patient outcomes and management. The study involves patients with PA undergoing adrenal venous sampling through either the antecubital or femoral vein to identify whether aldosterone overproduction is coming from one side or both sides of the adrenal glands. This procedure helps classify the subtype of PA, which guides treatment decisions including potential adrenalectomy. The study also aims to refine AVS protocols and standardize clinical practice. Participants will be monitored for major adverse cardiovascular events (MACE) for one year after the AVS procedure. Researchers will assess clinical and biochemical outcomes to better understand the impact of AVS-guided management on patient prognosis. The study collects detailed information to optimize diagnosis, treatment decisions, and long-term care for individuals with primary aldosteronism.
