Overview
Dr. Jen Ashton hosts this ABC News special on heart disease, the number one killer in America — claiming one life every 36 seconds. The segment introduces three distinct risk categories through real patient stories.
Key Details
Typical risk patients have known underlying conditions. The top five risk factors are high blood pressure, diabetes, high cholesterol, smoking, and family history. Kristin, a typical risk patient, had a blood sugar of 580 and was told the heart attack or undiagnosed diabetes could have killed her that night. Invisible risk patients have no underlying conditions — their risk factors hide in their DNA. Bob Harper, the Biggest Loser trainer and fitness expert, suffered a heart attack and cardiac arrest while working out in his own gym. He was saved only because someone called 911 and a doctor happened to be present. His story illustrates that peak physical fitness doesn't guarantee heart safety.
Why It Matters
New risk from COVID-19 emerged in patients like George Garrett, who developed myocarditis (inflammation of the heart muscle) and atrial fibrillation after COVID — despite having no prior heart conditions. While this affects a small subset of COVID patients, it represents a new category doctors are monitoring. The hopeful message: 90% of heart disease is completely preventable. The key is knowing your risk factors, listening to your body, and not waiting until your 30s to start caring about heart health. All three patients emphasize that if something feels off, don't ignore it — go get checked.
