Causes & Risk Factors
Causes and risk factors
In pediatric and young adult populations, SCA is primarily due to undetected genetic conditions that can be (usually) detected with general heart screenings/examinations. These “heart screenings” typically include a physician collecting a detailed medical and family history from a patient, performing a physical examination with an emphasis on auscultation (listening) to the heart with a stethoscope, administering an electrocardiogram (ECG/EKG), and/or an ultrasound (echocardiogram) of the heart.
There are various conditions that can predispose a young individual to SCA. These conditions can be summarized into four main categories: heart valve disorders, cardiomyopathies and conditions that change the heart muscle, genetic disorders, and congenital heart defects.
