For 75 years, research programs funded by the National Heart, Lung, and Blood Institute (NHLBI) have made important discoveries, developed cures, created new treatments, and improved the lives of people around the world.

Patients have always been at the center of this work. Working together, scientists, doctors, nurses, patients, and many others interested are advancing science and health.

Today, our challenge is to preempt heart, lung, and blood conditions before they start. In this vision, each person gets the right treatment as soon as they need it.

Join us in celebrating the incredible progress that has been made thus far and exploring how we can build on the NHLBI Strategic Vision for the next five years.
