Background: Coronary artery disease is the principal cause of disability and mortality worldwide. Its prevalence is increasing around world. It is about 75% of deaths occurring in developing countries like Bangladesh. It is very important to know about the inflammatory risk factors of coronary artery disease for early assessment of coronary artery disease. Serumβ2-microglobulin (²2m) is a newly identified biomarker that has been found to increase in patients with coronary artery disease. Aims: To determine the role of â2m in predicting the severity of coronary artery disease. Methods: This cross-sectional study was carried out in Department of Cardiology and Laboratory Medicine, BSMMU, Shahbag, Dhaka during March 2017 to February 2018. Total seventy four patients who underwent coronary angiography as per criteria where included in this study. Serum β2-microglobulin (²2m)was done before angiography procedure by indirect ELISA method and severity of coronary artery disease was assessed by extent of diseased coronary vessels and SYNTAX score. Results: β2-microglobulin level was found higher (≥3/ml) in coronary artery disease patients which was statistically significant (p<0.001).β2-microglobulin was also correlated with number of diseased coronary vessels (r=0.562, p<0.001). Mean â2m level was found 4.48±0.95 μg/ml with range from 3-6.1 μg/ml and the mean SYNTAX score was found 16.27±08.99 with the range from 1 to 44. Pearson’s correlation coefficient was done between â2m level and SYNTAX score. Then the result is r=0.547 and p<0.001. Therefore, there was a positive correlation between â2m level and SYNTAX score. The area under the receiver-operator characteristic (ROC) curves ²2m cut off value of 3.6 with 81.4% sensitivity and 86.7% specificity as the value for identifying the coronary artery disease. Conclusion: Our study revealed that β2-microglobulin effectively correlates with the severity of coronary artery disease. So it may be used as a reliable marker for assessment of coronary artery disease severity. University Heart Journal Vol. 16, No. 1, Jan 2020; 22-27

Abstract Background Chemerin – a recently described hormone is secreted by adipose tissue. It exerts proinflammatory action, leads to insulin resistance, but also has potentially favorable effects: it increases eNOS activity and is pro-angiogenic. Increased serum concentrations of chemerin was observed in patients with coronary artery disease (CAD). The role of chemerin in pathogenesis of CAD is not well understood. Purpose The aim of this pilot study was to assess the role of chemerin in pathogenesis of atherosclerosis, its impact on condition of large arteries and prognosis in CAD. Methods We included in the study patients with stable CAD who underwent percutaneous coronary intervention (PCI) in the past. Chemerin levels were measured with ELISA method. All patients had routine blood tests and insulin levels measured. Patients without history of diabetes also had OGTT. Status of large arteries was evaluated with carotid ultrasound, pulse-wave velocity (PWV) and ankle-brachial index (ABI). Body composition was assessed wit DEXA method. Anatomical severity of CAD was evaluated with SYNTAX score. One-year composite endpoint included death, myocardial infarction, revascularization, stroke and hospitalization for cardiovascular reasons. Results The study group comprised 163 patients (mean age 59.8± years, 26% of females, n=43). Mean chemerin level was 284.8 ng/ml. There was no significant difference in chemerin concentrations between patients with diabetes and remaining ones (with prediabetes and with normal glucose levels) 306.8±121 vs 274.15±109 pg/ml, p=0.1. In Spearman test chemerin level correlated with total fat mass (R=0.15, p=0.047), trunk fat mass (R=0.16, p=0.039), android fat mass (R=0.16, p=0.036), and BMI (R=0.18, p=0.028). Chemerin also correlated with white blood cells (WBC) count (R=0.34, p&lt;0.0001), hsCRP (R=0.16, p=0.03), total cholesterol (R=0.17, p=0.028), LDL cholesterol (R=0.19, p=0.01), HDL cholesterol (R=−0.21, p=0.006), triglicerides (R=0.3, p&lt;0.0001), platelet count (R=0.23, p=0.002), fasting insulin (R=0.22, p=0.004) and c-peptide (R=0.26, p=0.0005). There was no significant difference in chemerin levels between patients with carotid atherosclerosis (n=93) and patients with normal carotid arteries (n=70), (300±124 vs 263±94 ng/ml, p=0.07). There were no significant associations between chemerin levels and PWV, ABI measurements, SYNTAX score, or 1-year prognosis. Conclusions This is the first study to show that in patients with CAD chemerin levels correlate with WBC and with android fat tissue mass. Additionally, chemerin levels positively correlated with other inflammation or insulin resistance markers, and with unfavourable lipid profile.
