Ventriculo-Arterial Coupling: Historical Foundations, Physiological Principles, and Clinical Relevance in Critical Care Hemodynamics.
Review in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Ventriculo-arterial coupling describes the interaction between ventricular contractile performance and the arterial system, integrating end-systolic ventricular elastance, arterial elastance, stroke volume generation, and cardiovascular efficiency into a unified physiological framework. Although historically rooted in pressure-volume analysis, time-varying ventricular elastance, and Windkessel-based arterial modeling, the concept has renewed clinical relevance because conventional hemodynamic variables such as blood pressure, cardiac output, and ejection fraction may not adequately reflect the efficiency of ventricular-arterial interaction. This narrative review synthesizes literature published between 1969 and 2026 on the historical foundations, physiological principles, measurement strategies, and clinical applications of ventriculo-arterial coupling, with emphasis on critical care hemodynamics, septic shock, heart failure, perioperative instability, and pediatric cardiovascular assessment. The review highlights that arterial elastance is not simply a measure of arterial wall stiffness but a composite index influenced by vascular resistance, arterial compliance, characteristic impedance, heart rate, systolic timing, and stroke volume. Noninvasive assessment methods have expanded clinical accessibility, yet their interpretation remains limited by methodological assumptions, physiological variability, and incomplete validation in rapidly changing hemodynamic states. Current evidence supports ventriculo-arterial coupling as a valuable interpretive tool for distinguishing impaired contractility, excessive afterload, vasoplegia, preload limitation, and inefficient cardiovascular energy transfer. Standardized measurement protocols, population-specific thresholds, and outcome-based validation are needed before coupling-guided management can be adopted as a therapeutic strategy. The key takeaway is that ventriculo-arterial coupling should currently be used to refine hemodynamic reasoning rather than as an isolated treatment target.
