ALPRECHT-QUIROZ, Paola et al. Cardiorenal syndrome: Clinical and echocardiographic aspects. Arch. Cardiol. Méx. [online]. 2020, vol.90, n.4, pp.503-510.  Epub 10-Fev-2021. ISSN 1665-1731.  https://doi.org/10.24875/acm.20000087.

Cardiorenal syndrome (CRS) is a disorder in which the heart and kidneys are involved, interacting and producing a dysfunction between them in an acute or chronic way. There are different clinical phenotypes well identified as “heart and kidney disorders in which acute or chronic dysfunction in one organ induces acute or chronic dysfunction in the other”. The high incidence of cardiovascular morbimortality in patients with chronic terminal kidney disease (CKD), especially heart failure (HF), initially causes a myocardial lesion that leads to ventricular remodeling, which induces the activation of compensatory mechanisms, among which the kidney is a fundamental part since it regulates the hydroelectrolytic homeostasis and thus the circulating volume, being this in the dialytic stage more evident. The functional and anatomical changes at cardiovascular level that occur in these patients are very prevalent, and include hemodynamic interactions of the heart and kidneys in heart failure and the impact of atherosclerotic disease in both organ systems. We also describe diagnostic and therapeutic strategies applicable to cardiorenal syndrome, which determine the importance of echocardiography as a useful diagnostic model. Finally, we analyze the possibilities of treatment and remission of cardiac functional alterations with renal transplantation in patients with T-CKD.
