MRI distinguishes different types of heart failure

MRI distinguishes different types of heart failure

US researchers have developed a way to measure blood flow and oxygen consumption in the legs of patients with heart failure. The technique could lead to more personalised treatment for patients, they claim.

Using MRI, Mark Haykowksy at the University of Texas at Arlington and colleagues measured blood flow and oxygen extraction and consumption after knee extension exercise in the legs of older patients with heart failure.

They found that blood flow and oxygen uptake recovery took longer in patients with reduced ejection fraction than in patients with preserved ejection fraction.

The new technique enables medical professionals to distinguish between different groups of patients with heart failure, which could lead to therapies that are better targeted to the individual.
