RESUMEN
Patients with cardiovascular disease (CVD) and chronic kidney disease (CKD) show high rates of cardiorenal outcomes. In addition, the progression towards renal failure and cardiovascular events rises as CKD worsens. Several studies suggest that the activation of the mineralocorticoid receptor (MR) induces cardiac and renal injury, including inflammation and fibrosis. Finerenone is a novel, nonsteroidal, selective MR antagonist (MRA) which has demonstrated anti-inflammatory and anti-fibrotic effects in pre-clinical studies. Moreover, two large trials (FIDELIO-DKD and FIGARO-DKD) investigated the renal and cardiovascular outcomes in patients with mild to severe CKD in type 2 diabetes which received finerenone. On these bases, this comprehensive review aims to summarize the current knowledge regarding finerenone and its effects on CKD and the cardiovascular system, emphasizing its role in modifying cardiorenal outcomes.
RESUMEN
A 55-year-old male affected by heart failure with reduced ejection fraction and a history of a transient cerebrovascular accident was accepted to the Cardiology Department for worsening dyspnea. A cardiopulmonary exercise test was performed after therapy optimization to further evaluate exercise intolerance. A rapid increase in the minute ventilation/carbon dioxide production slope, end-tidal oxygen pressure, and respiratory exchange ratio, with a concomitant decrease in end-tidal carbon dioxide pressure and oxygen saturation, were observed during the test. These findings indicate exercise-induced pulmonary hypertension leading to a right-to-left shunt. Subsequent echocardiography with a bubble test unveiled the presence of an unknown patent foramen ovale. It is, therefore, necessary to exclude a right-to-left shunt by cardiopulmonary exercise testing, particularly in patients predisposed to develop pulmonary hypertension during exercise. Indeed, this eventuality might potentially provoke severe cardiovascular embolisms. However, the patent foramen ovale closure in patients with heart failure with reduced ejection fraction is still debated because of its potential hemodynamic worsening.
