Steroid shot before angioplasty may limit heart damage
NCT ID NCT05462730
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether giving a single, strong dose of steroids to people right after a major heart attack (STEMI) could reduce the amount of heart muscle that gets permanently damaged. The steroid was given before the standard emergency procedure to open the blocked artery. The trial involved 530 adults with chest pain lasting less than 12 hours. The main goal was to measure the final size of the heart injury using MRI scans.

Inclusion Criteria: 1. Age ≥18 years including fertile women (It is not possible to perform a pregnancy test (HCG urine test) in the pre-hospital setting. However, methylprednisolone is not contraindicated in pregnant women). 2. Acute onset of chest pain with \< 12 hours duration. 3. STEMI as characterized on electrocardiogram (ECG) by one of the following: 1\) at least two contiguous leads with ST-segment elevation ≥2.5 mm in men \< 40 years, ≥2 mm in men ≥40 years, or ≥1.5 mm in women in leads V2-V3 and/or ≥1 mm in the other leads, 2) presumed new left bundle branch block with ≥1 mm concordant ST-segment ele-vation in leads with a positive QRS complex, or concordant ST-segment depression ≥1 mm in V1-V3, or discordant ST-segment elevation ≥5 mm in leads with a negative QRS complex, 3) Isolated ST depression ≥0.5 mm in leads V1-V3 and ST-segment elevation (≥0.5 mm) in posterior chest wall leads V7-V9 indicating posterior acute myocardial infarc-tion (AMI), 4) ST-segment depression ≥1 mm in eight or more surface leads, coupled with ST-segment elevation in aVR and/or V1 suggesting left main-, or left main equivalent- coronary obstruction. Exclusion Criteria: 1. Presentation with cardiac arrest (out of hospital cardiac arrest (OHCA)). 2. Time from symptoms onset to primary PCI \> 12 hours. 3. Known allergy to glucocorticoid or known mental illness with maniac or psychotic episodes. 4. Patients with previous acute myocardial infarction (AMI) in the assumed culprit artery. 5. Previous coronary artery bypass graft (CABG). 6. Unable to read and understand Danish.
