Now the question became: "What would Alpha Phi do in peacetime?"
At that time, rheumatic fever - a disease that causes serious, debilitating damage to the heart - was a leading killer of school age children in the United States. Alpha Phi wanted to help these children, but also wanted freedom to contribute money and service to other programs. Cardiac aid fit the bill - chapters and members were able to donate funds and service to various educational and research projects.
During the next few decades, modern antibiotic therapy sharply reduced mortality and cases of rheumatic fever became rare. Heart disease became the #1 killer of women in North America, and Alpha Phi Foundation thought it fitting that an organization of women help fight it.
