Friday was Go Red for Women day - where people wore red to bring awareness about heart disease during American Heart Month.
Heart disease is the leading cause of death in women and many cases are preventable.
Holly Weiss first visited Dr. Anu Lala, a cardiologist at Mount Sinai Hospital, in 2019 after experiencing a racing heart and shortness of breath.
Weiss says when she put on her smartwatch, it showed that her heart rate was twice what it should be sleeping.
Lala diagnosed her with heart failure and put her on medication, a new diet and exercise. Weiss was also a busy professional in a high-stress legal job.
Weiss founded the nonprofit StandUp! Girls and has worked with kids in both the Bronx and Brooklyn.
