Effectiveness of pulmonary artery catheter monitoring for patients with cardiogenic shock of various causes: a systematic review and meta-analysis.

Overall, our meta-analysis demonstrated no significant association between PAC monitoring and in-hospital mortality among patients managed for cardiogenic shock. The use of PAC in the management of cardiogenic shock caused by acute decompensated heart failure was associated with lower in-hospital mortality, but there was no association between PAC monitoring and in-hospital mortality among patients with cardiogenic shock caused by acute coronary syndrome.
