Assessing Cardiac Function in Heart Failure Patients

Myocardial Reserve in Advanced Heart Failure Patients

Early Phase 1 Interventional University of Chicago · NCT05700617

This study is testing if a heart medication called milrinone can improve heart function and outcomes for people with heart failure who need advanced treatments.

What this trial studies

This study aims to evaluate whether differences in myocardial reserve can predict clinical outcomes in patients with heart failure. It is designed as a prospective, observational, crossover study that involves assessing invasive hemodynamics through right heart catheterization. Patients will be randomized to receive milrinone to determine its effects on cardiac function and outcomes. The study focuses on patients referred for advanced heart failure therapies or those with worsening clinical status requiring accurate hemodynamic assessment.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with a left ventricular ejection fraction (LVEF) of 40% or less who are referred for right heart catheterization.

Not a fit: Patients with severe, non-revascularized coronary artery disease or those with concurrent acute coronary syndrome may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the prediction of clinical outcomes for heart failure patients, leading to better-targeted therapies.

How similar studies have performed: Other studies have shown promise in using invasive hemodynamics to predict outcomes in heart failure, suggesting this approach may be effective.
