- Analysis of the Correlation Between Central Obesity and Abdominal Aortic Diseases(2019) APOLONI, Rafael Correa; ZERATI, Antonio Eduardo; WOLOSKER, Nelson; SAES, Glauco Fernandes; WOLOSKER, Marina; CURADO, Taina; PUECH-LEAO, Pedro; LUCCIA, Nelson DeBackground: Atherosclerosis and abdominal aortic aneurysms (AAAs) have several similar risk factors but different pathogenesis. Inflammation of the arteries is common to both. Central obesity can act as an endocrine organ through the secretion of inflammatory cytokines, and the perivascular fat has a local effect that could contribute to diseases of the abdominal aorta. Although the relation between central obesity and atherosclerosis occlusive arterial disease has been demonstrated, the correlation with AAA has conflicting results. The aim of this study was to analyze the correlation between central obesity and the presence of abdominal aortic diseases using computed tomography. Methods: Six hundred thirty-nine consecutive patients classified into 3 groups (AAA, aortic atherosclerotic occlusive disease (AAOD), and without aortic disease [control group]) who underwent computed tomography had the aorta diameter, the visceral fat area (VFA), and the subcutaneous fat area (SFA) measured at the level of third and fourth lumbar vertebrae. Results: VFA showed no difference between the groups. SFA was lower in atherosclerotic group (AAOD) than control (P < 0.01 in general and P < 0.04 in male). In AAA group, we found in men that the first tertile of aorta diameter had higher VFA than third tertile (P = 0.02). Conclusions: There was no difference in VFA between patients in AAA, AAOD, and without aortic disease groups. In men with aneurysm, there was an inverse relationship between VFA and aortic diameter. In AAOD, visceral to subcutaneous ratio is higher due to lower SFA.
- Influence of Criteria Used in Determining Prevalence of Metabolic Syndrome (NCEP-ATPIII versus IDF) in Patients with Intermittent Claudication(2014) ZERATI, Antonio Eduardo; GUIMARAES, Ana Lucia Monteiro; CARVALHO, Heitor Andrei Miranda de; SAES, Glauco Fernandes; RAGAZZO, Luciana; WOLOSKER, Nelson; LUCCIA, Nelson deBackground: In patients with peripheral arterial disease, metabolic syndrome is associated with less favorable evolution of intermittent claudication. Methods: The aims of this study were to determine the prevalence of metabolic syndrome in claudicant patients using the IDF and the NCEP-ATPIII criteria, and to assess the level of agreement between the two definitions. Results: In this cross-sectional study, 200 consecutive patients with intermittent claudication (65% male) were classified with or without metabolic syndrome according both criteria. The kappa coefficient was used to assess the level of agreement. Prevalence of metabolic syndrome was 60.5% when using the NCEP-ATPIII definition and 66.5% when using the IDF definition (P = 0.088). Among men, the prevalence of MetS was 55.4% according to the NCEP-ATPIII and 63.1% according to the IDF (P = 0.110) and, among women, 70.0% according to the NCEP-ATPIII and 72.9% according to the IDF (P = 0.754). Conclusion: Although the prevalence rates were similar, the reliability analysis showed that the agreement was substantial only among women and just moderate in the total population and among men.
- Graduated Compression Stockings Does Not Decrease Walking Capacity and Muscle Oxygen Saturation during 6-Minute Walk Test in Intermittent Claudication Patients(2017) CAVALCANTE, Bruno Remigio; RITTI-DIAS, Raphael Mendes; SOARES, Antonio Henrique Germano; DOMINGUES, Wagner Jorge Ribeiro; SAES, Glauco Fernandes; DUARTE, Flavio Henrique; CRUZ, Aline de Paula da; WOLOSKER, Nelson; PUECH-LEAO, Pedro; CUCATO, Gabriel Grizzo; ZERATI, Antonio EduardoBackground: We analyze the effects of graduated compression stoking (GCS) on walking capacity and oxygen saturation in intermittent claudication (IC) patients. Methods: Eighteen patients with IC performed the 6-minute walking test in 2 conditions in random order: GCS or placebo sock. Onset claudication distance and total walking distance were obtained. The calf muscle oxygen saturation was continuously monitored before, during, and after 6-minute walk test. Comparisons of the walking capacity and StO(2) parameters between GCS and placebo conditions were analyzed by Wilcoxon rank-sum test. Results: The onset claudication distance (GCS: 120 +/- 99 meters vs. placebo: 150 +/- 126 meters; P= 0.798) and total walking distance (GCS: 330 +/- 108 meters vs. placebo: 324 +/- 60 meters; P= 0.130) were similar between conditions. There were no differences in StO(2) parameters between conditions (P > 0.05). Conclusions: GCS does not decrease walking performance and calf muscle oxygenation saturation during 6-minute walk test in patients with IC.
- Calf Muscle Oxygen Saturation during 6-Minute Walk Test and Its Relationship with Walking Impairment in Symptomatic Peripheral Artery Disease(2018) ANDRADE-LIMA, Aluisio; CUCATO, Gabriel G.; DOMINGUES, Wagner J. R.; GERMANO-SOARES, Antonio H.; CAVALCANTE, Bruno R.; CORREIA, Marilia A.; SAES, Glauco F.; WOLOSKER, Nelson; GARDNER, Andrew W.; ZERATI, Antonio E.; RITTI-DIAS, Raphael M.Background: Impaired microcirculation is associated with poor walking capacity in symptomatic peripheral artery disease (PAD) patients during treadmill test; however, this test does not simulate the efforts of daily walking of these patients. Thus, the aim of the study was to describe the microcirculation responses during a 6-minute walk test (6MWT) and to analyze the relationship between microcirculation indicators and walking impairment in symptomatic PAD patients. Methods: Thirty-four patients were included (mean age = 67.6 +/- 11.2 years). Their clinical characteristics were collected, and they performed a 6MWT, in which the initial claudication distance (ICD) and total walking distance (TWD) were recorded. During and after the 6MWT, calf muscle oxygen saturation (StO(2)) parameters were monitored continuously to measure microcirculation behavior. The association between calf muscle StO(2) parameters and walking impairment were analyzed by Pearson or Spearman correlations. Results: Walking impairment was not associated with any StO(2) parameters during exercise. In contrast, after 6MWT, recovery time of StO(2) (r = -0.472, P = 0.008) and recovery time to maximal StO(2) (r = -0.402, P = 0.019) were negatively correlated with ICD. Furthermore, the distance walked under claudication symptoms (ATWD-ICD) was positively correlated with recovery time to maximal StO(2) (r = 0.347, P = 0.048). Conclusions: In symptomatic PAD patients, shorter ICD values during a 6MWT are associated with a delayed recovery in calf muscle StO(2) after exercise. Calf muscle StO(2) parameters decrease subtly during 6MWT, suggesting that the degree of ischemia in the calf muscle during ground walking, simulating efforts of the daily walking, is relatively low.
