Hyperaldosteronism Clinical Trial
Official title:
Primary Aldosteronism: a Study of Diagnostic Approach and Treatment Outcome in Western Norway
In this study the investigators aim to identify and include consecutively patients with primary aldosteronism (PA) diagnosed in the Western and Mid-parts of Norway, to describe the characteristics of these patients, to explore the cardiac effects of PA before and after specific treatment, and to identify long-term outcomes after treatment. One subgroup of the PA patients perform echocardiography to assess left ventricular systolic myocardial function before and after treatment. One subgroup of PA patients perform cardiac MRI to assess myocardial mass, myocardial fibrosis and myocardial function in rest and during stress, before and after treatment. For the cardiac MRI substudy, the PA patients are compared with a group of healthy controls, also included in the study. From 2022 onwards, PA patients diagnosed or subtyped with adrenal vein sampling at Oslo University Hospital will additionally be included in the study, thereby providing a national registration of PA patients.
From June 2013, all newly diagnosed patients with primary aldosteronism (PA) either diagnosed at Haukeland University Hospital (HUS) or admitted to HUS for subtype testing with adrenal vein sampling, have been asked for inclusion in the study. All included patients have a base-line study visit where clinical information is registered, and baseline blood and urine samples are collected. Echocardiography will be performed in a subgroup of patients before and 1 year after start of specific PA treatment. After start of definite medical or surgical treatment the patients are followed up with regularly new study visits. From 2020 onwards, PA patients diagnosed or subtyped with adrenal vein sampling at Oslo University Hospital will additionally be included in the study, thereby providing a national registration of PA patients. A subgroup of the included PA study patients also perform a Cardiac MRI. Cine-MRI, velocity-encoded MRI, MRI images during continuous adenosine infusion and MRI images after gadolinium contrast injection are performed, and compared to a group of age- and sex-matched healthy controls. From 2020 onwards, PA patients either diagnosed or performing subtyping with adrenal vein sampling at Oslo University Hospital will likewise be asked for study inclusion. ;
