Objective:

To examine the association of MRI-derived wedge pressure and pulmonary transit measures with myocardial fibrosis and clinical outcomes in patients with heart failure, specifically focusing on how these measures correlate with patient prognosis.

Approach:

Key Findings:

• MRI-derived indices correlate significantly with myocardial fibrosis and clinical outcomes, indicating their potential utility in risk stratification.
• The MRI-based model for estimating PAWP demonstrates superior accuracy compared to traditional echocardiography.
• Metrics of pulmonary transit time and blood volume provide valuable prognostic information for heart failure patients.

Interpretation:

MRI offers a non-invasive alternative to assess haemodynamic congestion and its implications in heart failure patients.

Limitations:

• The single-centre nature of the study may limit the generalizability of the findings to broader populations.
• Exclusion of patients with certain arrhythmias may introduce bias and affect the applicability of results to the general heart failure population.

Conclusion:

MRI can effectively assess haemodynamic congestion and provide prognostic information in heart failure.
