Current investigations illuminate several interlinked key points that should guide clinical practice and research priorities, including the following aspects: (1) cardiorenal interactions in critical cardiovascular disease and extracorporeal support are common and prognostically important; (2) optimal timing, modality, and integration of rrt with other extracorporeal technologies remain unresolved and likely require syndrome- and device-specific approaches; and (3) future progress needs pragmatic trials and mechanistic studies that account for device-organ crosstalk and patient-centered outcomes.  \nFirst, the epidemiology and prognostic implications of acute kidney injury/renal replacement therapy (aKi/rrt) in cardiovascular critical care are stark [4] . large registry- and cohort-derived data reviewed show aKi incidence of roughly 30–85% depending on the population and definition, and rrt utilization that varies widely (a few percent to >50%) in extra-corporeal membrane oxygenation (ECMo) and cardiogenic shock cohorts [5,6] . importantly, both critical cardiovascular disease and those receiving temporary mechanical circulatory support face substantially higher risks of aKi and rrt and, correspondingly, higher short-term mortality [7,8] . the Canadian review on rrt in cardiogenic shock summarized these points and emphasized that rrt in this context is associated with markedly worse outcomes—a consistent finding across the collection [9] .  \nSecond, the limitations of extrapolating general iCU rrt trial data to cardiovascular populations might exist. randomized timing trials in heterogeneous critically ill cohorts (ElaiN, aKi Ki, Starrt-aKi and related trials) have not demonstrated clear survival benefits for early universal initiation of rrt and in some cases signaled harm (infections, dialysis-dependence) [10] . these trials largely under-represent critical cardiovascular disease and ECMo patients, whose hemodynamic vulnerabilities and susceptibility to volume-related organ interactions differ fundamentally from septic or postoperative cohorts [11] . thus, the ‘one-size-fits-all’ timing paradigm is unlikely to be optimal for cardiovascular extracorporeal settings. the review authors therefore reasonably propose tailored thresholds-for example, a lower pH threshold and explicit consideration of diuretic-resistance and venous congestion as indications for rrt in cardiogenic shock - while acknowledging that prospective data are lacking [9] . these individualized thresholds reflect the unique physiology of cardiogenic shock, in which severe venous congestion, impaired renal perfusion, and metabolic acidosis progress differently compared with sepsis or postoperative states. lower pH thresholds, refractory diuretic resistance, and clinical evidence of venous hypertension are therefore used as early surrogates of impending organ injury in this population.  \nthird, papers analyzing ECMo-associated aKi reinforce the bi","cbCaibY36PvswBeF","https://ap.wps.com/l/cbCaibY36PvswBeF","pdf",478629,"English","# Editorial\n## Background and rationale\n## Epidemiology and prognostic implications\n## Limitations of extrapolating general ICU trial data\n## ECMO-associated bidirectional device–kidney interactions\n## Modality and practical integration","[{\"question\":\"Why is AKI and RRT especially important in cardiovascular critical care?\",\"answer\":\"AKI and the need for RRT are pervasive complications in critically ill cardiovascular patients, with higher risks and higher short-term mortality in those receiving temporary mechanical circulatory support.\"},{\"question\":\"What is the key problem with applying general ICU RRT timing trial results to cardiovascular populations?\",\"answer\":\"Randomized timing trials in heterogeneous ICU cohorts have not shown clear survival benefits for early universal initiation, and the evidence may be limited because critical cardiovascular and ECMO patients are under-represented and have different hemodynamic vulnerabilities.\"},{\"question\":\"How should timing and indications for RRT be approached in cardiogenic shock?\",\"answer\":\"The article suggests tailored thresholds using syndrome-specific physiology, such as considering lower pH thresholds and explicit attention to diuretic resistance and venous congestion, while noting prospective data remain lacking.\"}]","Integration of continuous renal replacement therapy in patients on extracorporeal life support - timing, modality, and future directions | PDF",1790730134]
