OBJECTIVES We assessed the relationship of season and weather types with myocardial infarction (MI) and sudden cardiac death (SCD) in a geographically defined population, and tested the hypothesis that the increased risk in winter was related to weather. BACKGROUND Winter peaks in coronary heart disease (CHD) have been documented. Yet, it is uncertain if seasonality exists for both incident e...
Among access control models, Role-Based Access Control (RBAC) is very useful and is used in many computer systems. Static Combination of Duty (SCD) and Dynamic Combination of Duty (DCD) constraints have been introduced recently for this model to handle dependent roles. These roles must be used together and can be considered as a contrary point of conflicting roles. In this paper, we propose sev...
BACKGROUND There are few data regarding the determinants of sudden cardiac death (SCD) in women, primarily because of their markedly lower rate of SCD compared with men. Nonetheless, existing data, although sparse, suggest possible gender differences in risk factors for SCD. METHODS AND RESULTS In this prospective cohort of 121 701 women aged 30 to 55 years at baseline, SCD was defined as dea...
Background Sudden cardiac death (SCD) is responsible for 11% of all deaths and 50% of all cardiovascular deaths. Hypertrophic cardiomyopathy (HCM) is the most common cause of SCD among the young patients. SCD is often the first manifestation of the disease. There are 5 major risk factors for SCD in patients with HCM. However, no single risk factor can be used as a screening test in assessment o...
BACKGROUND The recently released 2014 European Society of Cardiology guidelines of hypertrophic cardiomyopathy (HCM) use a new clinical risk prediction model for sudden cardiac death (SCD), based on the HCM Risk-SCD study. Our study is the first external and independent validation of this new risk prediction model. METHODS AND RESULTS The study population consisted of a consecutive cohort of ...
Sickle cell disease (SCD) is a debilitating single gene disorder caused by a single point mutation that results in physical deformation (i.e. sickling) of erythrocytes at reduced oxygen tensions. Up to 75% of SCD in newborns world-wide occurs in sub-Saharan Africa, where neonatal and childhood mortality from sickle cell related complications is high. While SCD research across the globe is tackl...
BACKGROUND In a recent cohort study, prolongation of the corrected QT interval (QTc) was associated with an independent increased risk of sudden cardiac death (SCD). We evaluated determinants of prolonged QTc and the relationship of prolonged QTc to SCD risk among patients with coronary artery disease in the general population. METHODS AND RESULTS A case-control design was used. Cases were SC...
BACKGROUND The management of sickle cell disease (SCD) has remained insurmountable in developing countries such as Uganda, because most communities are not aware of it. OBJECTIVE To determine knowledge gaps, attitudes and beliefs of the communities about sickle cell disease in Eastern and Western Uganda. DESIGN Cross sectional descriptive study. SETTING The districts of Sironko and Mbale ...
Objective. Sickle cell disease (SCD) is a disease that requires a significant degree of medical intervention, and family physicians are one potential provider of care for patients who do not have access to specialists. The extent to which family physicians are comfortable with the treatment of and concerned about potential complications of SCD among their patients is unclear. Our purpose was to...
BACKGROUND Sudden cardiac death (SCD) occurs commonly after heart transplantation (HTX). The utilization of surface electrocardiography (ECG) to assess post-HTX SCD has not been investigated thoroughly. This study aimed to investigate the specific changes in surface ECG in HTX patients with SCD. METHODS A total of 227 HTX patients (age 48 ± 14 y/o, mean donor age 34 ± 14 y/o, 173 males) were ...
