Background: Inflammation has been shown to play a role in atherosclerosis and acute coronary syndrome. This study was carried out to evaluate the relationship between baseline white blood cell (WBC) count and C-reactive protein (CRP) with angiographic severity of coronary artery disease in patients with acute coronary syndrome and to identify those subsets of patients with acute coronary syndrome who may need to undergo invasive or conservative strategies.Method: A total of 100 patients with acute coronary syndrome including unstable angina, non-ST elevated myocardial infarction & ST elevated myocardial infarction were evaluated in National Institute of Cardiovascular Disease (NICVD), Dhaka with a view to correlate angiographic findings, C-reactive protein and WBC count. Results: This study observed that either raised WBC count or raised CRP independently and combination of both WBC count and CRP elevation were significantly associated with more severe coronary artery disease. Either raised WBC count or raised CRP or combination of raised WBC    count and CRP were significant predictor of multivessel disease and high stenosis score. Conclusion: Elevation of WBC count and CRP in patients with acute coronary syndrome are associated with severe coronary disease. WBC count and CRP can be used as a new and even simpler tool for risk stratification in acute coronary syndrome. DOI: http://dx.doi.org/10.3329/cardio.v5i1.12209 Cardiovasc. j. 2012; 5(1): 23-29

SummaryThe aim was to measure the level of antibodies to oxidized LDL (oxLDL) and C-reactive protein (CRP) in the serum of patients with acute coronary syndrome (ACS). The results were correlated with data obtained from patients with stable coronary artery disease (stable CAD) and healthy controls.Thirty-three patients with ACS and 62 stable CAD patients were enrolled in the study. Fifty healthy individuals served as controls.The evaluation of anti-oxLDL autoantibodies was performed by ELISA, while CRP levels were measured by turbidimetry. The level of antibodies to oxLDL was significantly higher in both groups of patients with ACS and stable CAD compared to controls.The comparison between the acute and stable groups showed that anti-oxLDL levels were higher in the acute group,but because of high SD, the difference was not significant. By performing group analysis, anti-oxLDL levels were found to be significantly higher in ACS patients with unstable clinical state (circulatory insufficiency, malignant arrhythmias, recurring ischemic pain, need for urgent coronary intervention and death). CRP level in patients with ACS was significantly higher than in those with stable CAD. A positive correlation was found between anti-oxLDL antibodies and CRP levels both in patients with ACS and stable CAD. The association between the two biomarkers was stronger in the ACS group. In conclusion, our findings support the notion that the presence of antibodies to oxLDL, a plaquespecific antigen, plays a major role as a predictor of complicated manifestations of ACS.

Abstract Background Brain-derived neurotrophic factor (BDNF) is a neurotrophine that plays a key role in the regulation of both central and peripheral nervous system. Moreover, BDNF is secreted in multiple tissues and exerts systemic, autocrine, and paracrine effects in the cardiovascular system. Of importance, BDNF expression was enhanced in macrophages and smooth muscle cells in atherosclerotic coronary arteries and may be involved in thrombus formation. Thus, BDNF has been suggested as an important link between inflammation and thrombosis, potentially involved in the pathogenesis of acute coronary syndrome (ACS). Purpose In our study we aimed at assessing serum levels of BDNF in patients with ACS, evaluating differences according to clinical presentation [ST-segment elevation myocardial infarction (STEMI) vs. Non-ST-segment elevation ACS (NSTE-ACS)]. Moreover, we assessed the presence of optical coherence (OCT)-defined macrophage infiltrates (MØI) in the culprit vessel of ACS patients and evaluated their relationship with BDNF levels. Methods ACS patients were prospectively selected. Blood samples were collected at admission and serum levels of BDNF were subsequently assessed. Presence of OCT-defined MØI along the culprit vessel was assessed. Results 166 ACS patients were enrolled [mean age 65.3±11.9 years, 125 (75.3%) male, 109 STEMI, 57 NSTE-ACS]. Serum levels of BDNF were higher among STEMI patients compared with NSTE-ACS [median (IQR) 2.48 pg/mL (1.54–3.34) vs. 2.12 pg/mL (1.34–2.47), p=0.007], while C-reactive protein levels did not differ between the two groups. OCT assessment was performed in 53 patients and MØI were detected in 27 patients. Of importance, patients with MØI in the culprit vessel had higher levels of BDNF compared with patients without MØI [median (IQR) 2.23 pg/mL (1.38–2.53) vs. 1.41 pg/mL (0.93–2.07), p=0.023], while C-reactive protein levels did not differ between the two groups. Of note, at multivariate regression analysis BDNF levels were independent predictor of MØI [OR: 2.20; 95% CI (1.02–4.74), p=0.043]. Conclusions Serum levels of BDNF may reliable identify the presence of local macrophage inflammatory infiltrates in patients with ACS. Moreover, BDNF levels are higher in patients with STEMI compared with NSTE-ACS. Taken together, these data suggest that BDNF may represent an interesting link between local inflammatory activation and enhanced thrombosis in ACS.
