Background: Oxidative stress in primary aldosteronism (PA) is thought to worsen aldosterone-induced damage by activating proinflammatoryprocesses. Therefore, we investigated whether inflammatory markers associated with oxidative stress is increased withnegative impacts on heart function as evaluated by echocardiography in patients with PA. Methods: Thirty-two subjects (mean age, 50.3±11.0 years; 14 males, 18 females) whose aldosterone-renin ratio was more than 30among patients who visited Severance Hospital since 2010 were enrolled. Interleukin-1β (IL-1β), IL-6, IL-8, monocyte chemoattractantprotein 1, tumor necrosis factor α (TNF-α), and matrix metalloproteinase 2 (MMP-2), and MMP-9 were measured. All patientsunderwent adrenal venous sampling with complete access to both adrenal veins. Results: Only MMP-2 level was significantly higher in the aldosterone-producing adenoma (APA) group than in the bilateral adrenalhyperplasia (BAH). Patients with APA had significantly higher left ventricular (LV) mass and A velocity, compared to those withBAH. IL-1β was positively correlated with left atrial volume index. Both TNF-α and MMP-2 also had positive linear correlationwith A velocity. Furthermore, MMP-9 showed a positive correlation with LV mass, whereas it was negatively correlated with LVend-systolic diameter. Conclusion: These results suggest the possibility that some of inflammatory markers related to oxidative stress may be involved indeveloping diastolic dysfunction accompanied by LV hypertrophy in PA. Further investigations are needed to clarify the role of oxidativestress in the course of cardiac remodeling.
