Right heart muscle mechanics in pulmonary hypertension with heart failure

Official title: Myocyte Mechanics of Right Ventricular Contractile Failure in Pulmonary Hypertension due to Heart Failure with Reduced Ejection Fraction

Funded at Johns Hopkins University · NIH-11324500 · Data updated 2026-11-12

Researchers are studying how the right heart muscle fails in people who have heart failure with reduced ejection fraction and high blood pressure in the lungs, to improve diagnosis and care.

Who could benefit from this research

Could help

Adults with heart failure with reduced ejection fraction and pulmonary hypertension who can perform exercise testing may be eligible.

Less likely to help

Patients without right-heart involvement or those unable to participate in exercise-based assessments may see limited direct benefit.

What this research studies

This project looks at how right ventricular heart muscle cells behave in patients with HFrEF and pulmonary hypertension. By measuring how these cells generate force during calcium activity and movement, the team aims to find better ways to identify early dysfunction during exercise. They will examine mechanisms linking myosin function to the heart’s ability to ramp up its force, hoping to connect cellular findings to clinical tests. The study builds on prior work in related patient groups and seeks to translate cellular insights into improved patient monitoring and treatment decisions.

Why it matters

Potential benefit: If successful, the research could lead to better diagnostic tools and therapies that target right-ventricle function in patients with heart failure and pulmonary hypertension.

How similar studies have gone: Previous work in related patient groups supports that cellular mechanisms can inform clinical measures of RV function, with this study extending those findings to a broader patient population.
