BACKGROUND: Data on the cardiovascular middle-term follow-up of patients with primary aldosteronism (PA) are scanty. AIM: To detect the cardiovascular effects of surgery in patients with aldosterone (ALD)-producing adenoma (APA) and of pharmacotherapy in those with bilateral adrenal hyperplasia (BAH), a prospective study involving 60 consecutive patients with PA was performed. MATERIAL/ METHODS: Clinical, biochemical, and cardiovascular assessment was obtained before and after (31.5±4.4 months) surgery or proper medical treatment (32.1±5.0 months) in 19 and 41 patients, respectively. RESULTS: As expected, plasma ALD normalized in all operated patients, while in the other group it did not change. Systolic and diastolic blood pressure decreased (p<0.001) after both treatments. However, absolute and percentage reduction was significantly more pronounced (p<0.01) in operated than in non-operated patients. Left ventricular (LV) mass showed significant reduction after surgery (LV mass g/m(2), p<0.0007; LV mass g/m(2.7), p<0.01), but no change after medical treatment, so that the differences between absolute and percentage values at follow- up were statistically significant (p<0.01) between groups. Basal LV mass/m(2.7) was positively associated with age (p<0.009), body mass index (p<0.0008), drug number (p<0.03), and ALD/plasma renin activity ratio (p<0.01). Allocating the patients according to plasma ALD and cardiac parameters, patients who presented ALD reduction during the study also had a decrement in cardiac mass (p<0.04). CONCLUSIONS: Our data indicate that in patients with PA the removal of ALD excess by surgery in APA is effective in reducing blood pressure and in improving cardiac parameters, while anti-hypertensive therapy in BAH shows less positive impact on cardiovascular system.
