Overview

Congestion, in a physiological and clinical sense, is the abnormal accumulation of blood or fluid within tissues, organs, or vessels, typically resulting from impaired venous return, increased capillary hydrostatic pressure, or fluid overload. Systemic and pulmonary congestion are central features of heart failure, in which the heart cannot maintain output without elevated filling pressures, leading to peripheral oedema, hepatic and renal congestion, and fluid in the lungs; volume overload in renal failure and during dialysis produces analogous problems. Congestion is assessed through clinical signs, imaging such as bedside lung ultrasound, and measures of volume status, and its management centres on relieving fluid overload and treating the underlying cardiac, renal, or vascular cause. The cardiorenal interaction is particularly important, since dysfunction of either organ exacerbates congestion in the other. In the upper airway and mucosae, congestion also denotes vascular engorgement contributing to obstruction and inflammation. Research published in this area by the journal touches these themes, including bedside lung ultrasound for assessment of volume status in chronic haemodialysis patients, heart failure in family-medicine practice, and cardiorenal signalling pathways in heart failure. These contributions illustrate the assessment and management of congestion arising from cardiac and renal dysfunction and the fluid-balance disturbances that accompany them.
