Sudden cardiac death risk prediction: comment on 'risk factor and prediction modeling for sudden cardiac death in women with coronary artery disease'.

摘要

There have been significant improvements in primary and secondary prevention of congenital heart disease (CHD), resulting in substantial declines in CHD mortality over the last several decades. Despite declining CHD mortality rates, the decline in sudden cardiac death (SCD) rates has not kept pace with that observed for other modes of CHD death. The proportion of CHD deaths that are sudden appears to be increasing despite advances in therapies directed against CHD and the growing use of implantable cardioverter-defibrillators (ICDs). This unfavorable trend is a consequence of our inability both to accurately identify those who will die suddenly of a lethal ventricular arrhythmia and to develop and/or disseminate SCD preventive strategies for all populations at risk.
