Current Use and Impact on 30-Day Mortality of Pulmonary Artery Catheter in Cardiogenic Shock Patients: Results From the CardShock Study

Background:Cardiogenic shock (CS) is the most life-threatening manifestation of acute heart failure. Its complexity and high in-hospital mortality may justify the need for invasive monitoring with a pulmonary artery catheter (PAC).Methods:Patients with CS included in the CardShock Study, an observational, prospective, multicenter, European registry, were analyzed, aiming to describe the real-world use of PAC, evaluate its impact on 30-day mortality, and the ability of different hemodynamic parameters to predict outcomes.Results:Pulmonary artery catheter was used in 82 (37.4%) of the 219 patients. Cardiogenic shock patients who managed with a PAC received more frequently treatment with inotropes and vasopressors, mechanical ventilation, renal replacement therapy, and mechanical assist devices (P < .01). Overall 30-day mortality was 36.5%. Pulmonary artery catheter use did not affect mortality even after propensity score matching analysis (hazard ratio = 1.17 [0.59-2.32], P = .66).
