Working to Prevent HCM and Sudden Cardiac Arrest 

Founded in 2011, the Peter Patrick Madigan Antonini (PPMA) Foundation is a California non-profit 501(c)(3) public benefit corporation established in memory of Peter Antonini, a native San Franciscan who suffered a sudden cardiac arrest in 2002 from an undetected genetic heart disease called hypertrophic cardiomyopathy (HCM). HCM occurs when the heart muscle becomes abnormally thick, making it harder for the blood to pump. The disease affects 1 in 500 people and is a common cause of cardiac arrest in young athletes.

To learn more about HCM, visit the Hypertrophic Cardiomyopathy Association or the Mayo Clinic HCM Definition, Symptoms & Prevention.
The PPMA Foundation hopes to raise funds necessary to support research, legislation and the prevention of HCM. The Antonini Family established the PPMA Foundation to honor Peter and ensure an ongoing commitment to educate the community and hopefully prevent future cases of sudden cardiac arrest related to HCM.
