Evaluating the diagnostic performance of Liaison® chemiluminescence assay as screening tool for detection of acute Epstein-Barr infection: A comparative study.

The present investigation assessed the Liaison® diagnostic performance in detecting Epstein-Barr (EBV) IgM-VCA in a large patient cohort, considering age and symptomatology. VIDAS® were employed as a benchmark for acute EBV infection. The study also probed other coexisting conditions and potential cross-reactivity for error sources.

Comparability of two different polyacrylamide gel electrophoresis methods for the classification of LDL pattern type.

Background: The measurement of small dense low-density lipoprotein (sdLDL) particles is relevant when assessing cardiovascular risk. However, there is as yet no referenced method for the determination of LDL subfractions or a standardized comparison of the methods currently available. Therefore, the aim of this study was to compare the pattern of LDL particles measured by polyacrylamide tube gel electrophoresis (PTGE) and polyacrylamide gradient gel electrophoresis (PGGE) and to correlate the results with triglyceride concentration.

Association between AT C573T polymorphism and cardiovascular risk factors in myocardial infarction.

Background: Polymorphisms in the AT1 gene have been associated with various parameters related to the pathogenesis of cardiovascular diseases and to myocardial infarction. This study analyzed the relationship between two polymorphisms of the angiotensin II AT-1 receptor gene (AT1_1166 and AT1_573) and the risk of ischemic heart disease by studying their association with several cardiovascular risk factors.

Methods: The sample population comprised 356 subjects: 174 patients who had survived myocardial infarction (61.

[Prevalence of metabolic syndrome in patients with coronary heart disease].

Background And Objective: We aimed to know the prevalence of classical cardiovascular risk factors, hyperinsulinism, insulin resistance and metabolic syndrome (MS) in a population with coronary heart disease (CHD) as compared with a population without personal or familial history of cardiovascular risk factors.

Subjects And Method: This was an observational and transversal study of cardiovascular risk factors making up the MS in an adult population. 367 subjects aged 35-79 years (268 men and 99 women) were studied; 185 had CHD (141 men and 44 women) and 182 (127 men and 55 women) were included as a control population.
