Assessment of the state of perfusion of the cardiac and kidneys – the importance in early diagnosis and prevention

Cardiorenal syndrome (CRS) refers to the intricate bidirectional relationship between the heart and kidneys, wherein acute or chronic dysfunction in one organ precipitates dysfunction in the other. This interaction is classified into five distinct subtypes, based on the primary organ affected and the chronicity of the condition. Key clinical challenges in managing CRS include the absence of effective tools for early diagnosis, prognosis, and the evaluation of therapeutic outcomes. Imaging modalities such as ultrasound, computed tomography (CT), nuclear medicine, and magnetic resonance imaging (MRI) are increasingly utilized to assess cardiovascular and renal diseases. The technological advancements of the past few decades have accelerated the development of sophisticated imaging techniques, offering promising biomarkers for morpho-functional evaluation and tissue characterization. It is essential for clinicians to be aware of the advantages, limitations, and clinical utility of each modality in the management of CRS.
