Trends in out-of-hospital coronary heart disease (CHD) death, a surrogate for sudden cardiac death (SCD), are important for understanding the decline in CHD mortality. Little is known about out-of-hospital CHD death without prior CHD diagnosis, the definition of unexpected SCD. The authors analyzed secular trends in CHD death and unexpected SCD over a 20-year period (1979–1998) to examine the a...
BACKGROUND Observational data on sudden cardiac death (SCD) in the young are scarce, but the SCD incidence of this study is to examine regional differences in SCD incidence within a population among young individuals (<40 years) and to assess whether regional incidences are associated with socio-economic status (SES ). METHODS SCD cases aged <40 years were identified in 12 provinces of the Ne...
Aims To test the value of Periodic Repolarization Dynamics (PRD), a recently validated electrocardiographic marker of sympathetic activity, as a novel approach to predict sudden cardiac death (SCD) and non-sudden cardiac death (N-SCD) and to improve identification of patients that profit from ICD-implantation. Methods and results We included 856 post-infarction patients with left-ventricular ...
DOI: 10.5935/abc.20150072 To date, a considerable amount of valuable information about the problem of sudden cardiac death (SCD) has been described. The incidence of SCD in the United States ranges between 180000-400000 cases per year1. Martinelli et al demonstrated an incidence of 21270 cases of SCD per year in the Metropolitan Area of São Paulo2. Recently, Braggion-Santos et al.3 described th...
There is increasing evidence that subjective cognitive decline (SCD) in individuals with unimpaired performance on cognitive tests may represent the first symptomatic manifestation of Alzheimer's disease (AD). The research on SCD in early AD, however, is limited by the absence of common standards. The working group of the Subjective Cognitive Decline Initiative (SCD-I) addressed this deficiency...
BACKGROUND Genome-wide association studies and candidate-gene based approaches have identified multiple common variants associated with increased risk of sudden cardiac death (SCD). However, the independent contribution of these individual loci to disease risk is modest. OBJECTIVE To investigate the cumulative effects of genetic variants previously associated with SCD risk. METHODS A total ...
Patients with hypertrophic cardiomyopathy (HC) die suddenly. Proposed risk factors for sudden cardiac death (SCD) in HC are youth, a family history of SCD, syncope, and ventricular tachycardia. Hemodynamic variables have not convincingly proved to be risk factors for SCD. Therefore, this study was designed to examine predictors of SCD in a large number of patients with HC during long-term follo...
Stearoyl-CoA desaturase (SCD) is a key enzyme that converts saturated fatty acids (SFAs) to monounsaturated fatty acids (MUFAs) in the biosynthesis of fat. To date, two isoforms of scd gene (scd1 and scd5) have been found widely existent in most of the vertebrate animals. However, the evolutionary patterns of both isofoms and the function of scd5 are poorly understandable. Herein, we aim to cha...
Safe and gentle exercise may be important for older adults overcoming a sedentary lifestyle. Sign Chi Do (SCD), a novel form of low impact exercise, has shown improved balance and endurance in healthy older adults, and there have been no SCD-related injuries reported. Sedentary older adults are known to have a greater cardiovascular (CV) response to physical activity than those who regularly ex...
