Abstract

Background: Identification of cardiogenic shock severity is a critical step to adapt the management level upon admission. Peripheral tissue perfusion signs, simple and reliable markers of tissue hypoperfusion have never been extensively assessed during cardiogenic shock. Methods: All consecutive patients admitted in ICU for cardiogenic shock of two tertiary teaching hospitals were included in a prospective observational study. Macro-hemodynamic parameters (such as heart rate, blood pressure, left ventricular ejection fraction and cardiac index) and peripheral tissue perfusion signs such as capillary refill time on the index fingertip, mottling and Pv-aCO2 (the difference between partial pressure of CO2 in venous blood and arterial blood) were recorded at inclusion (H0), H6, H12, H24 and H48. The composite primary endpoint was the association between 90-day mortality or the need for venoarterial-ECMO support. Results: 61 patients were included; at inclusion, simplified acute physiology score II was 64 (52-77) points. The primary endpoint was met by 42% of patients. Capillary refill time values were significantly higher at all time-points in non survivors or patients needing venoarterial-ECMO support. In univariate analysis, capillary refill time > 3 sec at inclusion was associated with 90-day all-cause mortality or venoarterial-ECMO support (Hazard Ratio of 12.38; 95% CI 2.91 to 52.71). Capillary refill time at inclusion was poorly associated with macrocirculatory parameters but significantly correlated with microcirculatory parameters. Further, capillary refill time added incremental value to Cardshock score, with an AUC combination at 0.93. Conclusion: In patients admitted in ICU for cardiogenic shock, our preliminary data suggest that a prolonged capillary refill time > 3 sec was associated with an early prediction of 90-day mortality or the need for venoarterial-ECMO support
