Determining the extent of coronary luminal stenosis is a key factor in management of CAD. Methods presently used are costly and pose certain dangers, ranging from nephrotoxicity to death. Long Pentraxin or Pentraxin-3 (PTX3) has been used to predict survival or atherosclerotic process, but not to identify coronary stenosis. Calcium Score has been used to this end with some success. Methods: Individuals with chronic stable angina, without evidence of Myocardial Infarction (MI), who were categorized as intermediate-risk after completing a treadmill exercise test, according to Duke Protocol, underwent cardiac catheterization. In addition, blood samples were drawn for coronary sinus PTX3, and also PTX3, uric acid, high-sensitivity C-reactive protein (hs-CRP), cholesterol, glucose and High-Density Lipo-protein (HDL) in peripheral circulation. Calcium Scores were calculated using Agatston Score and non-contrast multi-slice CT scan. Participants were divided according to the number of stenotic coronary arteries (patent, one-, two-and three-vessel disease). Results: We found that PTX3 levels in coronary sinus and femoral vein correlated with each other, after log-transforming the values. Also we found that PTX3 levels and Calcium Scores differed among individuals with triple-vessel involvement and individuals without significant stenosis in any of coronary arteries. No significant differences were observed, regarding hs-CRP levels. Conclusion: PTX3 levels in periphery correlate with those in coronary arteries, and this variable can be measured with a less invasive procedure. In addition to Calcium Score, PTX3 levels are different in our four groups. The combined contribution of PTX3 and calcium score may help us identify individuals with significant coronary artery stenosis without needing to perform cardiac catheterization in a select group of patients.展开更多

Objective: The aims of this study were to measure the level of serum pentraxin-3 in patients with suspected coronary artery disease (CAD) and to determine whether it was associated with the severity of CAD. Material and Methods: The serum pentraxin-3 level was measured by enzyme-linked immunosorbent assay in 80 patients who were referred for elective coronary angiography due to positive stress test results. SYNTAX score was used to determine the severity of CAD. Results: The study cohort consisted of 45 (56.25%) males and 35 (43.75%) females with a mean age of 55 ± 9.8 years. The mean serum pentraxin-3 level was 3.79 ± 1.38 ng/ml, and the mean SYNTAX score was 15.8 ± 11.3. A significant correlation was observed between pentraxin-3 level and SYNTAX score (r = 0.459, p - 32 or ≤22 (p = 0.002). Conclusion: The serum level of inflammatory marker pentraxin-3 is increased in patients with CAD and is correlated with the severity of CAD.展开更多

The aim of this study was to measure the serum pentraxin-3 level in anterior ST-segment elevation myocardial infarction (STEMI), to investigate correlation with the left ventricular (LV) systolic function assessed by speckle tracking echocardiography, and compare with the well-established cardiac biomarkers of myocardial injury such as troponin-I. Methods: Serum pentraxin-3 level was measured by ELISA in 50 patients with anterior STEMI. LV strain was measured by speckle tracking echocardiography. The results were compared to twenty sex- and age-matched persons who had history of stable angina and normal LV ejection fraction (LVEF). Results: Serum level of pentraxin-3 was significantly higher in STEMI patients in comparison to the control group (8.3 ± 3.1 versus 3.4 ± 1.2 ng/ml, p 0.001). Average LV global longitudinal strain (GLS) was reduced in STEMI patients in comparison to control subjects (11.2 ± 2.4 versus 20.2 ± 2.1, p 0.001). In addition, there was a significant negative correlation between serum pentraxin-3 level and LVEF (r = -0.557, p 0.001) and the average LVGLS (r =-0.529, p 0.001). Serum pentraxin-3 cutoff value > 8.3 ng/ml had sensitivity of 81.8% and specificity of 86.4% to detect LVEF less than 50% (p 0.001). While, peak cardiac troponin-I level > 34 ng/ml was 86% sensitive to detect LVEF less than 50% with specificity of 90.9%. Conclusions: The elevated serum level of pentraxin-3 and cardiac troponin-I in STEMI patients and their association with both LVEF and GLS support the concept that the magnitude of these biomarkers correlates to the severity of myocardium injury.展开更多

Methods Wild-type C57BL/6 mice(12-14 weeks old) were randomly divided into 3 groups. Mice in the group 1(n=12) and group 2(n=12) were instilled with lipopolysaccharide via intratracheal or intraperitoneal routes, respectively. Mice in the group 3(n=8) were taken as blank controls. Pulmonary morphological and functional alterations were measured to determine the presence of experimental ALI. PTX3 expression in the lung was quantified at both protein and m RNA levels. PTX3 protein concentration in blood and bronchoalveolar lavage fluid was measured to evaluate its ability to diagnose sepsis-induced ALI by computing area under receiver operator characteristic curve(AUROCC). Results ALI was commonly confirmed in the group 1 but never in the other groups. PTX3 expression was up-regulated indiscriminately among lipopolysaccharide-challenged mice. PTX3 protein concentration in the biofluid was unable to diagnose sepsis-induced ALI evidenced by its small AUROCC. PTX3 concentration in bronchoalveolar lavage fluid did not correlate with that in serum. Conclusions Lipopolysaccharide challenges induced PTX3 expression in mice regardless of the presence of ALI. PTX3 may act as an indicator of inflammatory response instead of organ injury per se.展开更多
