What this trial studies

This clinical trial evaluates the effectiveness of the hypotension prediction index (HPI) in preventing low blood pressure during cardiac surgery. It involves a randomized, single-blind design where adult patients scheduled for elective primary cardiac surgery will be assigned to either HPI-guided or standard hemodynamic management. The primary focus is on measuring the average time patients experience hypotension during surgery, while secondary outcomes include monitoring postoperative complications. The study aims to confirm the clinical benefits of HPI in a cardiac surgery setting.

Who should consider this trial

Good fit: Ideal candidates are adults undergoing elective primary coronary artery bypass grafting (CABG) or isolated valve surgery.

Not a fit: Patients with arrhythmias, intracardiac shunts, or those requiring urgent/emergent procedures may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of hypotension and related complications during and after cardiac surgery.

How similar studies have performed: Previous studies have shown promising results for the hypotension prediction index in non-cardiac surgeries, but its application in cardiac surgery remains to be fully validated.
