Abstract

Primary aldosteronism (PA) is the most common cause of secondary hypertension. Overseas flow surveys show that compared with essential hypertension (EH), the risk of cardiovascular and cerebrovascular diseases and kidney damages in PA patients is increased, and the mortality rate of cardiovascular events is higher than that in EH patients, in addition,this effect is independent of elevated blood pressure. The difference of cardiac damage between PA and EH patients was analyzed by echocardiography. Methods From April 28, 2017 to April 28, 2019, patients with primary aldosteronism diagnosed by ICD in Department of Endocrinology and Metabolism, Department of Cardiology and Urology were extracted from the adrenal group database of the Department of Endocrinology and Metabolism, West China Hospital of Sichuan University, and ICD diagnosis in Department of Endocrinology and Metabolism during the same period was also extracted. In patients with essential hypertension, the differences of clinical indicators and echocardiography between the two groups were compared, and the differences of cardiac damage and related risk factors between the two groups were explored. Results 295 patients were included in this study, including 148 patients in PA group (50.17%) and 147 patients in EH group (49.83%). There was no significant difference in gender, age, BMI, course of disease and average blood pressure between the two groups (P > 0.05). The levels of serum aldosterone and BNP in PA group were significantly higher than those in EH group, and the levels of serum renin and minimum blood potassium were significantly lower than those in EH group (P < 0.05). Left ventricular diameter (LV), left atrial diameter (LA), interventricular septal thickness (IVS), left ventricular posterior wall thickness (LVPW), ascending aorta diameter (AAO), end-diastolic diameter (EDD), end-diastolic volume (EDV) and stroke volume (SV) in PA group were significantly higher than those in EH group (P < 0.05). It was significantly higher than that in EH group (P < 0.05). The correlation analysis of variables with statistical significance between the two groups showed that serum renin activity level was negatively correlated with LV, AAO, EDD and SV, and the lowest serum potassium level was negatively correlated with LVPW and AAO. CONCLUSION Compared with EH of the same age, course of disease and blood pressure level, PA patients are more likely to suffer from cardiac damage, which is manifested by heart growth, ventricular septal thickening and cardiac function decline, and is closely related to the inhibition of serum renin activity and serum potassium level. Clinical attention should be paid to early screening and treatment of PA and its complications in order to reduce the risk of cardiac death.Key words: primary aldosteronism; echocardiography; cardiovascular risk factors
