Tiny gene could hold key to treating malignant cardiac arrhythmia

Cardiac arrhythmias affect millions across the world and are responsible for a fifth of all deaths in the Netherlands. Currently there are multiple treatment options, ranging from life-long medication to invasive surgical procedures. Research from Amsterdam UMC and Johns Hopkins University, published today in the European Heart Journal, sets another important step in the hunt for a one-off gene therapy that could improve heart function and protect against arrhythmias.
