Scientists find genetic marker that indicates a person’s risk for tachycardia-induced cardiomyopathy

August 9, 2018

Scientists in Japan have found a potential marker to identify which people with abnormally fast heartbeats are at high risk of developing heart failure.

The results were published in June in Circulation: Genomic and Precision Medicine, a journal from the American Heart Association.

Atrial fibrillation, or chronically, abnormally fast heartbeat, can be a symptom of a potentially fatal disease known as tachycardia-induced cardiomyopathy (TIC). The condition can be reversed and damage can be prevented, but only if the heartbeat is brought back into proper rhythm through drugs or catheter therapy.
