Abstract
Abstract
Context Primary aldosteronism (PA) represents the most frequent cause of
endocrine arterial hypertension. PA is also common in patients with mild forms
of hypertension and normokalemia.
Objective To identify the prevalence of PA in newly diagnosed hypertensive
patients in primary care in Southern Germany.
Patients and methods Newly diagnosed hypertensive patients in 27 primary
care centers in Munich agreed to participate in the study. Patients were
screened for PA using the aldosterone-to-renin ratio (ARR). In case of elevated
ARR, confirmation testing was performed. After the diagnosis of PA, subtype
differentiation and subsequent therapy of PA were initiated.
Results A total of 235 patients with newly discovered arterial
hypertension were initially screened for PA. Among these, 35 were excluded
because the medication indicated pre-existing treated arterial hypertension or
they were on interfering antihypertensive medication. At the first screening,
2.0% of the patients had hypokalemia. Of the 200 patients with newly
discovered arterial hypertension, 42 had an elevated ARR. The incidence of the
presence of hypokalemia did not differ according to normal or pathological ARR.
Nine patients (21%) did not show up for further testing and were lost to
follow-up, and 33 patients underwent a saline infusion test. Of these, 11
patients were diagnosed with PA, leading to at least 5.5% prevalence of
PA in the collective. None of the diagnosed PA patients was hypokalemic at
screening.
Conclusion A 5.5% prevalence of PA was observed in our data of
untreated newly diagnosed patients with hypertension.
