INTRODUCTION AND OBJECTIVES: @entity384 ( @entity384 ) is endothelium-dependent and can be assessed by ultrasound in the brachial artery. We sought to determine the most suitable position for the occlusion cuff for the study of @entity384 in three groups of adult @entity1 . SUBJECTS AND METHODS: We included 160 subjects, mean age 58.5 7.8 years: 40 healthy subjects, 80 with cardiovascular risk factors, and 40 @entity1 with AMI. In a subgroup of 60 subjects, the first 10, 30, and 20 of each group, respectively, @entity384 was evaluated twice, after upper arm occlusion and @entity432 to induce @entity450 . RESULTS: In the initial substudy, the @entity384 after upper arm occlusion was 7.6 2.4% in healthy subjects, 5.1 2.2% in @entity1 with risk factors (p < 0.0001), and 3.5 2.2% in AMI @entity1 (p < 0.041, with respect to the risk-factor group). @entity384 after @entity432 was 4.6 1.5%, 2.3 2.1% (p < 0.006), and 2.2 1.9%, respectively, with no significant statistical differences between the risk-factor and AMI groups. Only upper arm occlusion was performed in the remaining @entity1 , as planned, because it provided the most accurate information. Overall, the @entity384 was, respectively, 7.8 3.1%, 5 2.6% (p < 0.0001) and 3.3 3% (p < 0.004, with respect to the risk-factor group). @entity384 was directly related to HDL @entity165 and inversely related to resting diameter and number of risk factors. CONCLUSION: The best approach to studying @entity384 is proximal occlusion since it allows for a better stratification of the with @entity409 . With this technique, a worsening of endothelial function in acute @entity583 can be demonstrated.
