A recent report stated that patients with primary aldosteronism who remain renin suppressed during mineralocorticoid receptor antagonist treatment might have a higher risk of developing cardiovascular disease than those with unsuppressed renin activity. We retrospectively investigated the incidence of composite cardiovascular disease and risk factors for cardiovascular disease in 1115 Japanese patients with primary aldosteronism treated with mineralocorticoid receptor antagonists. The median follow-up period was 3.0 years, and the incidence of cardiovascular events was very low (2.1%) throughout 5 years of follow-up. Changes in plasma renin activity from before to after mineralocorticoid receptor antagonist treatment were divided into three groups based on tertile, low, intermediate, and high plasma renin activity change groups, with incidences of cardiovascular disease events of 2.1%, 0.5%, and 3.7%, respectively. Multivariate Cox regression analysis revealed age (adjusted hazard ratio, 1.07; 95% confidence interval, [1.02–1.12]) and body mass index (adjusted hazard ratio, 1.13 [1.04–1.23]) as independent risk factors for cardiovascular disease. The high plasma renin activity change group had significantly higher cardiovascular disease risk with mineralocorticoid receptor antagonist treatment than the intermediate plasma renin activity change group (adjusted hazard ratio, 5.71 [1.28–25.5]). These data suggest that a high change in renin level after mineralocorticoid receptor antagonist treatment may not necessarily predict a better prognosis of cardiovascular disease in patients with primary aldosteronism.
