Researchers determine genetic cause of Timothy syndrome
Howard Hughes Medical Institute researchers have pinpointed the genetic cause of a devastating but rare childhood disorder, called Timothy syndrome, which underlies a form of severe cardiac arrhythmia. Children who have the syndrome develop spontaneous genetic mutations that interfere with calcium channels that regulate the excitation and contraction of the heart. The researchers have also identified a class of drugs that they hope will alleviate the arrhythmia. (2004-09-30)

New system would vastly improve heart defibrillation

ESC Congress 2004: Atrial fibrillation patients often receive needless treatment
Results of the Euro Heart Survey on atrial fibrillation (AF), presented today, demonstrate that many AF patients receive clot-preventing drugs while not at risk for stroke. Also, patients are given rhythm control drugs despite the fact that they never were symptomatic. These drugs may induce intracranial bleeding as well as sudden death, respectively. Insight into the data of this survey may help reducing redundant and potentially dangerous treatments in AF patients. (2004-08-29)

Heartless worms hold clues to cardiac arrhythmias, sudden death

Implanted defibrillators not covered for half of patients who could benefit, study finds
In a vivid illustration of the tradeoffs that society faces in this age of costly new medical technology, new research examines the potential impact of Medicare's decision to cover lifesaving implanted devices only for certain heart patients, and not for others. The analysis shows that more than half of heart failure patients who would be good candidates for implanted cardioverter-defibrillators (ICDs) would not qualify for reimbursement under current Medicare guidelines.

Women who drink may be at greater risk of cardiovascular complications than men
Chronic, heavy alcohol consumption can increase the prevalence of cardiovascular complications, including hypertension, cardiomyopathy, arrhythmia, and stroke. Some female alcoholics experience more severe cardiovascular effects from heavy drinking than male alcoholics; these effects are noted earlier and at lower consumption levels than those noted in men. Women who drink chronically may also be at risk for future cardiovascular complications. (2003-09-14)

St. Jude Medical announces publication of results of its ADOPT-A trial
The results of the ADOPT-A clinical trial are being published in the Aug. 20 edition of JACC and represent the first peer-reviewed publication of this data. The ADOPT-A clinical trial evaluated the use of St. Jude Medical's AF Suppression(tm) pacing algorithm to suppress symptoms related to paroxysmal and persistent atrial fibrillation (PAF). For patients getting pace makers or for those who have been fitted with St. Jude's pacemaker already, this relatively new algorithmic technology is revolutionary. (2003-08-19)
