Anesthesia-linked heart injury after non-cardiac surgery
Official title: Anesthesia Induced Myocardial Injury in Non-cardiac Surgery (AIMY)
Run by University Hospital Tuebingen · NCT07179029 · Data updated 2026-11-12
This project will see if anesthesia and non-cardiac surgery are linked to increases in cardiac troponin (a marker of heart muscle injury) in adults aged 40–80 who have at least two cardiovascular risk factors.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 40–80 having elective or emergency non‑cardiac surgery who have at least two cardiovascular risk factors, an ASA status of II–IV, and can give written informed consent are ideal candidates.
✕Probably not a fit
Young, low‑risk patients, those undergoing cardiac or obstetric procedures, minor surgeries without anesthesia, or patients unable to consent are unlikely to benefit from participation.

What this trial studies
This is an observational study enrolling adults 40–80 undergoing elective or emergency non‑cardiac surgery with at least two cardiovascular risk factors and ASA II–IV. Researchers will obtain perioperative cardiac troponin measurements and collect clinical data to identify episodes of myocardial injury and their timing. The protocol excludes cardiac and obstetric procedures, minor surgeries not requiring anesthesia, and patients unable to give consent. Analyses will describe the frequency, timing (with attention to the first two postoperative days), and risk factors associated with perioperative myocardial injury.
Why it matters
Potential benefit: If successful, findings could help clinicians detect high‑risk patients earlier and guide monitoring or preventive strategies to reduce perioperative cardiac complications.
How similar studies have gone: Previous observational work (for example Botto et al.) has shown that perioperative troponin rises are common and predict worse outcomes, so the approach is supported by existing evidence though not proven to change outcomes yet.

Landiolol to prevent fast heart rates during major non-cardiac surgery in patients with cardiovascular risk
This will test whether giving the ultra‑short acting beta‑blocker landiolol to people over 45 with cardiovascular risk factors who are having major non‑cardiac surgery can keep heart rate below 90 bpm throughout the perioperative period and reduce heart injury.
