Predictors of acute mortality in patients with cardiogenic shock treated with Impella device - Predictors of acute mortality in patients treated with Impella device

Sixty-seven with cardiogenic shock with Impella were evaluated. The 30-day mortality rate and rate of requiring escalation therapy were 24% and 18%, respectively. The P terminal force in lead V1 (PTF) was significantly higher in the deteriorated group than in the recovered group (0.052+/-0.032 vs. 0.022+/-0.010 mms, respectively; p<0.001). On ROC analysis, PTF>0.035 mms identified the deteriorated group with a sensitivity of 73% and specificity of 96% (AUC=0.93, p<0.001).
