Up to 450,000 Americans die each year from a sudden and fatal heart condition, and in just over one in ten cases the cause remains unexplained even after an autopsy.
Now, researchers at the University of Maryland School of Medicine (USA) have seen that almost 20% of patients who suffer sudden unexplained cardiac death, the majority of whom under 50 years, carried rare genetic variants. These variants are likely to increase the risk of sudden cardiac death.
In some cases, their deaths may have been avoided if your doctors had information about your genetic predisposition to heart disease. The study findings were published in “JAMA Cardiology.”
