Polimorfismo S447X da lipase lipoprotéica: influência sobre a incidência de doença arterial coronariana prematura e sobre os lípides plasmáticos The S447X polymorphism of lipoprotein lipase: effect on the incidence of premature coronary disease and on plasma lipids

Abstract

OBJETIVO: O objetivo deste estudo foi avaliar o efeito do polimorfismo S447X sobre os lípides plasmáticos em pacientes com doença arterial coronariana (DAC) prematura. MÉTODOS: Os lípides plasmáticos e a genotipagem foram determinados em 2 grupos: 313 pacientes com DAC prematura (OBJECTIVE: The objective of this study was to evaluate the effect of polymorphism S447X on plasma lipids of patients with premature coronary artery disease (CAD). METHODS: Plasma lipids and genotypes were determined in 2 groups: 313 patients with premature CAD (<55 years of age) and 150 controls without CAD. RESULTS: Frequency of the S447X polymorphism was 18% in patients with CAD and 23% in the control group. The S447X polymorphism of lipoprotein lipase is related to a decrease in plasma triglyceride concentrations in male patients with CAD, but this correlation is not observed in female patients. CONCLUSION: The presence of the S447X lipoprotein lipase polymorphism was not associated with the incidence of CAD.
