From humble beginnings, the AHA has grown into the nation’s oldest and largest voluntary organization dedicated to fighting heart disease and stroke. A shared focus on cardiovascular health unites our more than 35 million volunteers and supporters as well as our more than 2,900 employees. Learn more about our lifesaving history.

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. Learn more about our life-changing funded research breakthroughs.
