The cure rate of hypertension after surgery for primary aldosteronism (PA) was assessed in a single institution. In the present study, we studied the risk factors on the cure rate of hypertension after surgery in patients with PA. Thirty-five patients who underwent surgery for PA between January 2004 and December 2009, with a follow-up time of 1 year or longer were studied. The mean age at surgery was 50.7 years old. The male to female ratio was 24 : 11. Factors confounding the cure rate of hypertension after surgery were analyzed using the univariate and the multivariate analysis. Nineteen (54%) of the 35 patients were completely cured after surgery. In most cases, a complete cure was seen within 1 month after surgery. At 1 year after surgery, the dose of medication for hypertension could be decreased in 11 (13%) of the 16 noncured patients. Although hypertension in patients with PA may be curable by surgery, the cure rate of hypertension after surgery has been reported to be from 16 to 67%. In the present study, age, gender, preoperative serum creatinine, the period of hypertension, the number of medications for hypertension, and family history for hypertension were significant in the univariate analysis for the cure rate of hypertension (persistent hypertension) after surgery. Multivariate analysis showed that the age of 55 years old or older was a significant predictor for non-curable hypertension after surgery. Our result suggests that earlier surgery may contribute to a better outcome on the cure rate of postoperative hypertension in patients with PA.
