Preoperative heart pumping power and P-POSSUM surgical risk score
Official title: Investigation of the Relationship Between Preoperative Cardiac Power Output and P-POSSUM Score
Run by Necmettin Erbakan University · NCT07454564 · Data updated 2026-11-12
We will test whether a quick preoperative measure of heart pumping power (cardiac power output) can help predict complications and death after abdominal surgery in people aged 65 and older.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are patients aged 65 or older with ASA class I–III who are undergoing abdominal surgery and who can have adequate transthoracic echocardiographic recordings and give informed consent.
✕Probably not a fit
Patients with advanced heart failure (EF <30%), severe valvular disease, recent or unstable coronary disease, pulmonary hypertension, severe arrhythmia, or those unable to undergo transthoracic imaging are unlikely to benefit from this approach.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is a prospective observational study of patients aged 65 and older undergoing elective or emergency abdominal surgery at a single center. Preoperative cardiac power output (CPO) will be obtained using noninvasive hemodynamic measurements performed as part of routine perioperative care, and P-POSSUM scores will be calculated using standard criteria. Patients will be followed postoperatively to record complications, mortality within the predefined follow-up window, and length of hospital stay. No additional interventions beyond standard clinical care are performed for the purpose of this study.
Why it matters
Potential benefit: If successful, adding preoperative CPO could improve accuracy of surgical risk estimates and help teams better target perioperative care to reduce complications.
How similar studies have gone: Prior work in cardiology and critical care has shown cardiac power output can predict outcomes, but applying preoperative CPO alongside P-POSSUM for abdominal surgery is relatively novel with limited direct evidence.
