Clinical analysis of 330 patients with primry aldosteronism / 中华内分泌代谢杂志

ABSTRACT

The clinical data of 330 patients with primary aldosteronism (PA) from January 2006 to March 2010 were retrospectively analyzed. The prevalence of 1, 2, and 3 stage hypertension in these subjects was 3.64％,20. 91％, and 75.45 ％, respectively. Of all PA patients, 89.09％ were young adults and 81.82％ were overweight or obese. There was a marked preponderance of male patients in the overweight or obese group ( P＜0. 01 ). The incidence of hypokalemia was 32. 12％. The concentration of serum potassium was not associated with the disease course. Logistic regression showed that the concentration of plasma aldosterone was an independent risk factor of hypokalemia in PA patients( P＜0. 01 ). 79. 09％ PA patients presented the plasma aldosterone level over 12 ng/dl and the renin activity level of less than 1 ng · ml-1 · h-1. The aldosterone-to-rennin activity ratio was ＞20 in 94.24％ of the patients with PA.
