Read our Heart Failure research guide →Researchers are studying patients with heart failure caused by something other than blocked arteries. This study looks at tiny blood vessel problems in the heart and how they affect whether patients improve with standard heart failure medications and care. The goal is to understand which patients are more likely to recover heart function and which may need different treatment approaches.
Many heart failure patients don't improve as much as doctors hope, even with the best available medications. Some evidence suggests that tiny blood vessel problems in the heart may predict who will recover and who won't—but doctors need more information to confirm this and use it to help patients.

You will undergo a coronary angiography (a procedure where dye is injected into heart blood vessels while doctors take images) and specialized measurements of blood flow in the smallest heart vessels. Doctors will also collect information about your heart function over time as you receive standard heart failure treatment. Your participation helps researchers understand the link between these tiny blood vessel problems and whether your heart function improves.
