American Heart Association

From humble beginnings, the AHA has grown into the nation’s oldest and largest voluntary organization dedicated to fighting heart disease and stroke. Heart disease is the No. 1 killer worldwide, and stroke ranks second globally. Even when those conditions don’t result in death, they cause disability and diminish quality of life. We want to see a world free of cardiovascular diseases and stroke. Our size and scope let us have real impact. The AHA has invested more than $5 billion in research, making us the largest not-for-profit funding source for cardiovascular and cerebrovascular disease research next to the federal government.
