A new study by researchers at Rhode Island Hospital provides much-needed insight into the molecular mechanisms that cause arrythmia, or irregular heartbeat, and how it triggers sudden cardiac death, one of the nation’s leading killers. Their findings, published online in the Journal of Clinical Investigation, could pave the way for the development of new, genetically-targeted therapies to treat and prevent fatal arrythmias.

Every year, 300,000 Americans die suddenly when, out of the blue, a “storm” of electrical activity arises within their heart muscle – so violent and so abrupt that their hearts just stop beating. These tragic and dramatic “sudden cardiac deaths” strike people young and old, often without warning.

Statin drugs, known primarily for their ability to lower cholesterol, also may reduce the overactive sympathetic nervous system response that contributes to the worsening of heart failure and increases the risk of sudden cardiac death, two University of Missouri-Columbia researchers have found. Heart failure is the leading cause of morbidity and mortality in the United States.
