About this trial

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.

Trial outcomes

Primary outcomes

1

Long-term clinical outcome after surgical and medical treatment of PA

Systolic and diastolic blood pressure (mm Hg) will be measured after specific PA treatment for estimation of clinical blood pressure outcome. In adrenalectomized patients clinical outcome will be determined following the international standardized Primary Aldosteronism Surgery Outcome (= PASO) criteria.

Time frame
5 years
2

Long-term biochemical outcome after surgical treatment of PA

Biochemical outcome after unilateral adrenalectomy will be determined by measurement of aldosterone (pmol/L), direct renin-concentration (mIE/L) for estimation of aldosterone/renin-ratio and potassium (mmol/L) in blood, following the international standardized PASO (primary aldosteronism surgery outcome) criteria.

Time frame
5 years

Secondary outcomes

1

Echocardiographic assessment of left ventricular mass in PA patients before and after treatment

Echocardiography is applied to assess the rate of increased left ventricular mass (g/m2.7 )before and after specific PA treatment. Data will be compared with a control group of patients with primary hypertension (HT), participating in the FAT-associated CardiOvasculaR dysfunction (FATCOR) study, which is a study cohort established at the European Society of Hypertension Excellence Centre in Bergen.

Time frame
3 years
2

Echocardiographic assessment of left ventricular systolic function measured as global longitudinal strain in PA patients before and after treatment

Echocardiography is applied to assess the rate of reduced left ventricular systolic myocardial function assessed as global longitudinal strain, before and after specific PA treatment. Data will be compared with a control group of primary hypertension participating in the FAT-associated CardiOvasculaR dysfunction (FATCOR) study, which is a study cohort established at the European Society of Hypertension Excellence Centre in Bergen.

Time frame
3 years
3

Echocardiographic assessment of left ventricular systolic function measured as midwall shortening in PA patients before and after treatment

Echocardiography is applied to assess the rate of reduced left ventricular systolic myocardial function before and after specific PA treatment, measured as midwall shortening (%). Data will be compared with a control group of primary hypertension participating in the FAT-associated CardiOvasculaR dysfunction (FATCOR) study, which is a study cohort established at the European Society of Hypertension Excellence Centre in Bergen.

Time frame
3 years
4

Incidence of reduced quality of life in PA patients before and after treatment, assessed by Short Form Health Surveys (SF-36/RAND-36)

Quality of life is measured in PA patients before, 1 year and 5 years after specific PA treatment, measured by the approved quality of life Short Form Health Surveys SF-36 and RAND-36, to detect the incidence of reduced quality of life compared with results from the healthy population. SF-36 was used in the period 2013-2016, and has from 2016 onwards been replaced by RAND-36.
