Risk stratification for arrhythmic sudden cardiac death: identifying the roadblocks.
Athough it is difficult to determine the precise number, the range for the number of sudden cardiac deaths (SCDs) per year in the United States alone has been reported from 184 000 to 462 000,1 with estimates that 50% to 70% are due to tachyarrhythmic mechanisms. Regardless of where within this range the true number lies, this represents a large epidemiological problem that warrants serious att...
متن کاملSudden arrhythmic death: from basic science to clinical practice
Sudden cardiac death refers to unexpected death attributable to a cardiac cause occurring within 1 h of the onset of symptoms (NICE, 2006). It often results from cardiac arrhythmias and is a major worldwide cause of morbidity and mortality. Arrhythmias account for 180,000 to 250,000 deaths per year in the United States and ∼70,000 deaths per year in the United Kingdom (NICE, 2006; Chugh et al.,...
متن کاملMitochondria oxidative stress, connexin43 remodeling, and sudden arrhythmic death.
BACKGROUND Previously, we showed that a mouse model (ACE8/8) of cardiac renin-angiotensin system activation has a high rate of spontaneous ventricular tachycardia and sudden cardiac death secondary to a reduction in connexin43 level. Angiotensin-II activation increases reactive oxygen species (ROS) production, and ACE8/8 mice show increased cardiac ROS. We sought to determine the source of ROS ...
متن کاملAngiotensin II-induced sudden arrhythmic death and electrical remodeling.
Rats harboring the human renin and angiotensinogen genes (dTGR) feature angiotensin (ANG) II/hypertension-induced cardiac damage and die suddenly between wk 7 and 8. We observed by electrocardiogram (ECG) telemetry that ventricular tachycardia (VT) is a common terminal event in these animals. Our aim was to investigate electrical remodeling. We used ECG telemetry, noninvasive cardiac magnetic f...
متن کاملPrediction of sudden cardiac death: appraisal of the studies and methods assessing the risk of sudden arrhythmic death.
Since the recognition of the high incidence of cardiac arrest as the mechanism of sudden cardiac death (SCD), medical scientists and clinicians have sought methods to predict and prevent these events. Significant progress has already been made in the prediction and prevention of life-threatening arrhythmias during the last decade. This progress is highlighted by the outcomes of 4 recently publi...
