Abstract

Background

Mechanical circulatory support is increasingly used in acute cardiogenic shock.

Objective

To assess treatment strategies for cardiogenic shock.

Methods

Data of 57 patients in acute intrinsic cardiogenic shock treated with ECMO were analyzed. Different subsequent strategies (weaning, VAD, transplantation) were followed.

Results

Overall 1, 2, and 4-year survival was 36.8 ± 6.4%, 32.2 ± 6.4%, 29.8 ± 6.3%. Elevated lactate and hemorrhagic complications (all p in patients with right heart failure prior to ECMO implantation, BVAD therapy showed a trend (p=0.058) towards superior survival compared with LVAD therapy. Seven of the BVAD patients received successful transplantation, with a 1-year survival of 71%. Among survivors Short Form 36 reported significantly lower combined physical scores (p=0.004).

Conclusions

Right heart assessment prior to ECMO implantation may be beneficial to provide tailored therapy if ECMO weaning fails. Survival after cardiogenic shock requiring ECMO seems to be associated with impaired long-term quality of life.
