Blood pressure clues may predict early death after heart attack
NCT ID NCT07586878
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study examines whether a low pulse pressure (the difference between top and bottom blood pressure numbers) in the first hours after a cardiac arrest is linked to early death. Researchers will analyze data from 3500 patients who had a cardiac arrest outside the hospital and are already part of a larger trial. The goal is to better understand which patients are at highest risk, not to test a new treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help doctors identify high-risk patients sooner after cardiac arrest, potentially guiding better care.
- What could go wrong
- This is an observational study, not a treatment trial. It only looks for associations, not cause and effect, so findings may not change practice.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Randomized STEPCARE participants with available trial data for STEP-PRESS analyses. The STEP-PRESS source population consists of randomized STEPCARE participants excluding consent withdrawals. The primary analysis population is restricted to participants alive 12 hours after randomization, without mechanical circulatory support initiated before or within 24 hours after randomization, and with sufficient valid blood-pressure observations during 0 to 12 hours after randomization.

Inclusion Criteria: * Randomized in the STEPCARE trial. * Out-of-hospital cardiac arrest. * Stable return of spontaneous circulation, defined in the parent STEPCARE protocol as at least 20 minutes without chest compressions. * Unconsciousness after sustained return of spontaneous circulation, defined as not being able to obey verbal commands, or intubated and sedated because of agitation. * Eligible for intensive care without restrictions or limitations. * Included in STEPCARE within the parent-trial inclusion window. * For STEP-PRESS analyses, availability of recorded STEPCARE blood-pressure data sufficient to calculate pulse pressure for the relevant analysis population. * For the primary STEP-PRESS analysis population: alive 12 hours after randomization, without mechanical circulatory support initiated before or within 24 hours after randomization, and with at least three valid recorded blood-pressure observations during 0 to 12 hours after randomization. Exclusion Criteria: * Withdrawal of consent for use of STEPCARE trial data. * Trauma or hemorrhage as the presumed cause of cardiac arrest. * Suspected or confirmed intracranial hemorrhage. * On extracorporeal membrane oxygenation before STEPCARE randomization. * Pregnancy. * Previously randomized in the STEPCARE trial. * For STEP-PRESS primary and 24-hour landmark analyses: mechanical circulatory support initiated before or within 24 hours after randomization. * For endpoint-specific analyses: missing data required to define the relevant exposure, outcome, or biomarker endpoint.
