In patients referred for coronary angiography, higher numbers of EPCs, and a trend toward higher numbers of CACs, were associated with the presence of significant CAD, and EPC number correlated with maximum angiographic stenosis severity. Endothelial progenitor cell levels were highest in patients with CAD selected for revascularization.
Obesity is pathogenically related to clinical and subclinical disorders that contribute to the development of atherosclerotic plaques and their complications leading to onset of cardiovascular events. Arterial stiffness may be an indicator of early vascular changes signaling the development of vascular disease. The purpose of this study was to assess the stiffness of the abdominal aorta using transthoracic echocardiography in normotensive obese and hypertensive obese pediatric patients and a control group. The study group consisted of 25 healthy children (M/F: 13/12) as a control group (Group I), 25 normotensive obese children (M/F: 13/12) (Group II) and 25 hypertensive obese children (M/F: 14/11) (Group III). The mean ages were 12.1 +/- 1.8, 11.9 +/- 1.5 and 12.4 +/- 1.4 years, respectively. Aortic strain (S), pressure strain elastic modulus (Ep) and normalized Ep (Ep*) measurements were significantly different in the hypertensive obese group, and cholesterol levels and body mass index were higher in this group. These findings may be important in determining the relationship between obesity and cardiovascular risk factors at pediatric age.
Although tuberculosis is rare in industrialized countries, in developing countries it remains one of the most important causes of large pericardial effusion and should be investigated and excluded in each patient.
Henoch-Schönlein purpura is the most common systemic vasculitis during childhood. Many antigenic stimuli and infectious agents have been proposed as a trigger of the disease. Group A beta-hemolytic streptococcus is the most common proposed infectious agent as a trigger for Henoch-Schönlein purpura. We report a 9-year-old boy who has Henoch-Schönlein purpura and acute rheumatic fever with complete atrioventricular block.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
