Why Athletes Collapse
from Nice Genes! · host Genome BC
The genetic clues behind sudden cardiac arrest in young individualsEvery so often, we see headlines about an elite athlete collapsing mid-game. The crowd goes silent, emergency crews rush to the field, and everyone’s left wondering: how could this happen? The truth is, sometimes a hidden heart condition written deep in our DNA will unmask itself on the field.In this episode, Dr. Kaylee Byers sits down with sports cardiologist and cardiogeneticist Dr. Prashant Rao to explore the genetic roots of sudden cardiac events in young athletes. Together, they unpack the most common underlying genetic conditions responsible, what genomics is revealing about the specific genes involved, and the ongoing debate around genetic screening. Plus, the remarkable story of JJ: a young wrestler who survived cardiac arrest thanks to his early genetic diagnosis and fast-acting friends.Listen in to learn why these devastating events happen, and how genomics is helping keep athletes safely in the game.Highlights(7:23) The most common underlying genetic heart conditions(11:40) Meet the 18 year old wrestler who survived cardiac arrest(21:32) A hot debate in sports cardiology(24:51) Tailoring training through genotype–Resources1. 78 minutes in the life (and near death) of Fabrice Muamba- The Guardian2.
