The American Heart Association is the nation’s oldest and largest voluntary organization dedicated to fighting heart disease and stroke. Founded by six cardiologists in 1924, our organization now includes more than 22.5 million volunteers and supporters. We fund innovative research, fight for stronger public health policies, and provide critical tools and information to save and improve lives. Our nationwide organization includes 156 local offices and more than 3,000 employees. We moved our national headquarters from New York to Dallas in 1975 to be more centrally located. The American Stroke Association was created as a division in 1997 to bring together the organization’s stroke-related activities. What We Do: To improve the lives of all Americans, we provide public health education in a variety of ways. We’re the nation’s leader in CPR education training. We help people understand the importance of healthy lifestyle choices. We provide science-based treatment guidelines to healthcare professionals to help them provide quality care to their patients. We educate lawmakers, policymakers and the public as we advocate for changes to protect and improve the health of our communities.
