Systolic blood pressure could predict survival rates for patients who suffer from cardiac arrests

A study written by SPHPM’s Dr Janet Bray, co-authored by Associate Professor Stephen Bernard, Kate Cantwell, Michael Stephenson and Karen Smith has found that different levels in systolic blood pressure in patients who have suffered a cardiac arrest, could be related to their survival rates after being discharged from hospital.

The paper entitled ‘The association between systolic blood pressure on arrival at hospital and outcome in adults surviving from out-of-hospital cardiac arrests of presumed cardiac aetiology’, aimed to explore the optimal blood pressure target following successful resuscitation from out-of-hospital cardiac arrest, and the association between level of systolic blood pressure on arrival at hospital and survival to hospital discharge.

According to the study, in an EMS system using intravenous adrenaline and fluids to maintain post-resuscitation systolic blood pressure, hypotension on hospital arrival was relatively uncommon. However, in presumed cardiac out-of-hospital cardiac arrests patients with an initial shockable rhythm, systolic blood pressures below 90 mmHg was associated with significant lower odds of survival to hospital discharge. This level of hypotension may indicate patients who require more aggressive post-resuscitation blood pressure management.
