February is Heart Health Month, a good time for all of us around the world to focus on the significance of heart health and disease. The World Health Organization reports that cardiovascular diseases are the No. 1 cause of death globally. In the video above, watch as our CEO, Oscar Munoz, recounts his personal experience of a heart attack and the critically important steps he took that helped save his life.

Oscar's story reminds us that heart disease is often unexpected, and preparedness is key to saving lives.
