BACKGROUND: Primary aldosteronism (PA) is one of the major etiologies for secondary hypertension featuring more prominent left ventricular hypertrophy. The purpose of the study was to investigate the predictive factors of left ventricular mass index (LVMI) regression in patients with PA after adrenalectomy.
METHODS: We prospectively analyzed 30 patients with aldosterone-producing adenoma (APA) who received adrenalectomy from October 2006 to September 2008. Echocardiography was performed preoperation and 1 year after operation.
RESULTS: Thirty patients with aldosterone-producing adenoma undergoing adrenalectomy were enrolled. In a 1-year follow-up, LVMI decreased significantly by an average of 18.6%. Net LVMI decrease (ΔLVMI) was associated with preoperative LVMI, preoperative serum potassium level, baseline systolic blood pressure (SBP), baseline diastolic blood pressure, net SBP decrease (ΔSBP), net diastolic blood pressure decrease, preoperative/postoperative change of log-transformed plasma aldosterone concentration, preoperative/postoperative change of log-transformed plasma renin activity, and preoperative/postoperative change of serum potassium level (Δserum potassium level). In a multiple regression analysis, preoperative LVMI (β = -0.287, P = 0.049), ΔSBP (β = 0.518, P = 0.01), and Δserum potassium level (β = -20.471, P = 0.014) were significantly correlated with ΔLVMI.
CONCLUSIONS: The LVMI in patients with PA regressed significantly after adrenalectomy. Preoperative LVMI, ΔSBP, and Δserum potassium levels are independent factors associated with the degree of LVMI regression.
