Aims: The haemodynamic effects of primary implantation of an intra-aortic balloon pump (IABP) versus inotropes in decompensated heart failure and low output (DHF-LO), but without an acute coronary syndrome, have not been investigated. We therefore aimed to investigate the effect of primary IABP implantation as compared to inotropes on haemodynamics in DHF-LO with no acute ischaemia. Methods and results: Patients (n=32) with DHF-LO despite IV diuretics were randomised to primary 50 mL IABP or inotropes (INO: enoximone or dobutamine). The primary endpoint was the improvement RI RUJDQ SHUIXVLRQ DVVHVVHG E\ ¨ PL[HGYHQRXV R[\JHQ VDWXUDWLRQ 6Y22 ) at 3 hours; secondary endpoints LQFOXGHG¨FDUGLDFSRZHURXWSXW&3217SUR%13SURSRUWLRQDOFKDQJHFXPXODWLYHIOXLGEDODQFHDQG¨G\Vpnoea severity score, all at 48 hours.

There were no IABPrelated serious adverse events (SAEs). Thirty-day mortality was 23% (IABP) vs 44% (INO). Conclusions: Primary circulatory support by IABP showed a significant increase in improved organ perfusion assessed by SvO2.
