Heart attack recovery: could a 24-Hour hospital stay be just as safe?
NCT ID NCT06744322
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether people who have a heart attack can be discharged from the hospital after about 24 hours instead of the usual 36 hours or more. Researchers want to see if early discharge is just as safe and does not increase the risk of death, another heart attack, or unplanned heart-related hospital visits. About 2,070 adults with uncomplicated heart attacks will take part.

Inclusion Criteria: * Uncomplicated acute myocardial infarction (NSTEMI and STEMI) diagnosed according to the 2023 acute coronary syndrome guidelines of the ESC * Age ≥ 18 years at time of consent * Invasive management strategy and in case of PCI successful intervention of the culprit lesion defined by post-interventional TIMI 3 flow * Ability to understand and willingness to sign and date written informed consent Exclusion Criteria: * Myocardial infarction complicated by cardiac arrest (out-of-hospital cardiac arrest/in-hospital cardiac arrest) * PCI-related complications (coronary perforation, side branch closure, inability to deliver stent/balloon, aortic dissection, allergic reaction grade ≥2, stroke/thromboembolism, access site complications including pseudoaneurysm, arteriovenous fistula, retroperitoneal hemorrhage and arterial dissection/occlusion or emboli) * Malignant arrhythmias including sustained ventricular arrhythmias and persistent bradycardia (\< 50 beats per minute due to sinus node or atrioventricular conduction system abnormalities, second- /third-degree atrioventricular block) after PCI * Ongoing hemodynamic instability (systolic blood pressure \<90 mmHg, elevated lactate concentrations, need for inotropes or vasopressors) * Ongoing respiratory instability defined by Killip class \>I (rales, pulmonary edema) * Ongoing quantitative disorders of consciousness (somnolence, sopor, coma) * Acute kidney injury defined by Kidney Disease Improving Global Outcomes (KDIGO) stages 2 and 3 * Pregnancy * Untreated critical non-culprit lesions requiring revascularization during index hospitalization not allowing fast discharge * Immobility/limited mobility or social circumstances that prevent fast discharge assessed by an interprofessional care team
