Objective: To evaluate the morpho-functional changes of the myocardium in patients with primary aldosteronism (PA). Design: An observational study in a university referral center for blood pressure diseases. Patients: Twenty-three patients with PA, 24 patients with essential hypertension (EH), and 15 normotensive controls (C) underwent conventional echocardiography with integrated backscatter (IBS) and tissue Doppler imaging l analysis. The corrected IBS (C-IBS) values and the systo-diastolic variation of IBS (CV-IBS) were performed at both interventricular septum and the posterior wall levels. TDI myocardial systolic (S(m)), early diastolic (E(m)), and late diastolic (A(m)) velocities of both left ventricular walls were also determined. Results: In PA patients, septal and posterior wall CV-IBS were significantly lower than C (p<0.0001) and EH patients (p<0.001). In EH, CV-IBS was significantly lower than C (p<0.001). Patients with PA exhibited lower S(m), lower E(m), and higher A(m), and a subsequently reduced E(m)/A(m) ratio than C (p<0.001 for all) and EH (p<0.01 for all) at interventricular septum and lateral wall levels. In the latter, S(m), E(m), and E(m)/A(m) ratio were lower and A(m) was higher than C (p<0.001 for all). In PA and EH patients, CV-IBS at both septum (r=-0.66, p<0.001) and posterior wall levels (r=-0.67, p<0.001) and S(m) peak of both septum (r=-0.52, p<0.001) and lateral wall (r=-0.55, p<0.001) were inversely related to plasma aldosterone. Conclusions: Patients with PA showed myocardial wall remodeling characterized by increased myocardial fibrosis and early left ventricular systodiastolic function abnormalities. (J. Endocrinol.

Abstract

Objective: To evaluate the morpho-functional changes of the myocardium in patients with primary aldosteronism (PA). Design: An observational study in a university referral center for blood pressure diseases. Patients: Twenty-three patients with PA, 24 patients with essential hypertension (EH), and 15 normotensive controls (C) underwent conventional echocardiography with integrated backscatter (IBS) and tissue Doppler imaging l analysis. The corrected IBS (C-IBS) values and the systo-diastolic variation of IBS (CV-IBS) were performed at both interventricular septum and the posterior wall levels. TDI myocardial systolic (S(m)), early diastolic (E(m)), and late diastolic (A(m)) velocities of both left ventricular walls were also determined. Results: In PA patients, septal and posterior wall CV-IBS were significantly lower than C (p<0.0001) and EH patients (p<0.001). In EH, CV-IBS was significantly lower than C (p<0.001). Patients with PA exhibited lower S(m), lower E(m), and higher A(m), and a subsequently reduced E(m)/A(m) ratio than C (p<0.001 for all) and EH (p<0.01 for all) at interventricular septum and lateral wall levels. In the latter, S(m), E(m), and E(m)/A(m) ratio were lower and A(m) was higher than C (p<0.001 for all). In PA and EH patients, CV-IBS at both septum (r=-0.66, p<0.001) and posterior wall levels (r=-0.67, p<0.001) and S(m) peak of both septum (r=-0.52, p<0.001) and lateral wall (r=-0.55, p<0.001) were inversely related to plasma aldosterone.
