Resuscitation
-
After successful resuscitation from cardiac arrest, prolonged contractile failure has been demonstrated in animal experiments. No systematic evaluation of myocardial contractility following successful resuscitation after human cardiac arrest exists. The aim of this study was to assess left ventricular contractility following human cardiac arrest with successful resuscitation. ⋯ The four control patients had normal left ventricular contractility on arrival (z 0.0, range - 0.9-0.8) and after 24 h (z 0.7, range - 1.5-2.7). In conclusion non-invasive wall stress analysis can be applied to quantitate systolic left ventricular function, which was severely compromised in most patients within the first 24 h after successful resuscitation. Whether depression of left ventricular function is caused by cardiac arrest itself or by the underlying disease remains speculative.
