Mammogram appointments delayed by up to 148 days: NYC report

New animal-model data provides insight into the molecular basis for cardiac alternans and its link to sudden cardiac arrest. In a heart failure model, the authors demonstrated that targeted genetic modification can suppress cardiac alternans and reduce life-threatening arrhythmias.

Intracardiac T-wave Alternans Predicts Imminent Ventricular Tachyarrhythmias in ICD Patients, Dr. Charles Swerdlow, Moderated Poster Session, May 6, 10:10-10:20 AM, Poster Town, Exhibit Hall

The authors conclude that T-wave alternans measured from an implantable cardioverter-defibrillator (ICD) predicts imminent life-threatening arrhythmias. ICDs that monitor TWA continuously may warn patients and initiate pacing therapies to prevent sudden cardiac arrest.

Latent Repolarization Abnormalities in Survivors of Unexplained Sudden Cardiac Arrest Unmasked by Provocative Drug Testing, Dr. Danna A. Spears, Poster Session, May 6, 9:00 AM-12:00 PM, Poster Town, Exhibit Hall

The authors report that a large proportion of unexplained cardiac arrest survivors exhibit T-wave alternans, and suggest that this novel finding may potentially help to identify first-degree relatives who may also be at risk for SCA.
