In a 1:1 propensity-score matched analysis, #MCS use was associated with a 24% relative reduction in 30-day all-cause mortality risk 🔻💀, but also with more complications (e.g., bleedings, access-site related ischemia) 🔺🩸.
Also, we observed a relevant interaction between this finding and #cardiogenicshock severity assessed by #SCAI class, indicating a relative mortality risk reduction especially in patients with deteriorating #cardiogenicshock
As this is a retrospective, non-randomized analysis, its results are most certainly impacted by selection bias and unmeasured/unknown confounders, so that causality cannot be concluded from this.
However, it is a first step to generate evidence for a field where evidence is scarce, and especially points out the need to investigate the use of #MCS in patients with #heartfailure related #cardiogenicshock by dedicated randomized controlled trials.
Especially the finding on the interaction with #cardiogenicshock severity as measured by #SCAI class is interesting, as it indicates potential for improved patient selection (e.g., improving the benefit-risk-ratio)
Last week, I successfully defended my PhD thesis @KarolinskaInstitutet This was an amazing journey centered around a controversial topic: ICDs for the primary prevention of SCD in HFrEF. Let´s have a look: 1/x
Two landmark RCTs, MADIT II and SCD-HeFT, have established the concept of ICDs for the primary prevention of SCD in patients with HFrEF by showing a survival benefit with this approach. nejm.org/doi/full/10.10…nejm.org/doi/full/10.10… 2/x
However, both trials enrolled patients long ago, so that the enrolled study population might no longer reflect contemporary patients with HFrEF. 3/x
Fresh off the press: Our new manuscript on LV unloading in cardiogenic shock patients treated with VA-ECMO! ahajournals.org/doi/abs/10.116…
A thread
1/14
In patients with severe cardiogenic shock, VA-ECMO is a feasible tool to provide sufficient circulatory support. However, it comes with a major limitation: Increase in LV afterload via retrograde perfusion of the aorta
2/14
Patients with cardiogenic shock already suffer from high LVEDP. Initiation of VA-ECMO tends to further increase LVEDP. This might not only hamper myocardial recovery, and thus impact weaning success, but can also lead to fatal complications such as LV thrombus formation
