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.

Atherosclerotic Process

The aim is to study the conditions of appearance and the features of course of the acute coronary syndrome (ACS) in patients with normal rates of lipid metabolism and to assess the influence of additional risk factors (uinary acid, C-reactive protein, fibrinogen) on the development of atherosclerotic process by assessment of surrogate markers of atherosclerosis the thickness of intima-media complex (TIMC) of carotid arteries (СА), the presence of atherosclerotic plaque (AP) in CA, the value of ankle-brachial index (ABI)) in patients with ACS without dyslipidemia (DLP). Materials and methods. The study included 66 patients without DLP (50 men and 16 women, the mean age - 53,7±10,6 years) with ACS, divided in groups depending on its forms: 1 group – patients with instable angina (IA), 2 group – patients with myocardium infraction (MI) without ST segment elevation and 3 group – patients with MI with ST segment elevation. The level of serum acid, C-reactive protein, fibrinogen in blood serum were detected and ultrasound examination of СА with detection of CA TIMC, presence of atherosclerotic plaque and measuring of arterial pressure on upper and low extremities with ABI calculation was carried out. Results. Among examined patients MI with ST segment elevation was diagnosed in 33 persons (50,0%); MI without ST segment elevation – in 18 (27,3%) and IA – in 15 (22,7%). The complicated ACS was observed in 20 (30,30%) persons. The value of CA TIMC among patients with MI with ST segment elevation was reliably higher than in patients with MI without ST segment elevation (р<0,001), and ABI was reliably lower in persons with MI and ST segment elevation (р<0,05) and IA (р<0,05) than in patients with MI without ST segment elevation. Correlative analysis demonstrated the interconnection between the levels of inflammation indicators (C-reactive protein, fibrinogen) in the blood serum and the value of CA TIMC and ABI. Conclusions. The persons without DLP need additional examination (detection of C-reactive protein, fibrinogen levels in blood serum, ultrasound of CA and detection of ABI) for more precise evaluation of ACS risk.

Abstract Background The association between the level of high sensitivity C-reactive protein (hsCRP) and coronary plaque characteristics in patients with acute coronary syndrome (ACS) remains to be elucidated. Purpose To clarify the morphological characteristics of culprit lesion in patients with ACS according to the hsCRP levels using optical coherence tomography (OCT). Methods A total of 215 consecutive patients with ACS, who underwent OCT imaging of culprit lesions were included. The patients were classified into either the higher hsCRP group (hsCRP ≥0.14 mg/dL, n=108) or the lower hsCRP group (hsCRP &lt;0.14 mg/dL, n=107) according to the median preprocedural hsCRP level. The morphological characteristics of culprit lesion assessed by OCT were compared between the two groups. Results The higher hsCRP group had higher prevalence of insulin therapy (14 vs. 6%, p=0.037) and current smoker than the lower hsCRP group (37 vs. 18%, p=0.002). The prevalence of long lesion (≥25 mm, 67 vs. 53%, p=0.041) and fibrocalcific plaque (53 vs. 33%, p=0.003) was significantly higher in the higher hsCRP group than in the lower hsCRP group (Figure). On the other hand, the prevalence of plaque rupture (36 vs. 46%, p=0.174) and lipid-rich plaque (47 vs. 64%, p=0.011) was rather lower in the higher hsCRP group than in the lower hsCRP group (Figure). In a multivariate analysis, fibrocalcific plaque (odds ratio [OR]: 2.098, 95% confidence interval [CI]: 1.125–3.913, p=0.019), lesion length (mm, OR: 1.036, 95% CI: 1.010–1.061, p=0.004) and current smoker (OR: 2.757, 95% CI: 1.388–5.476, p=0.003) was independently associated with higher hsCRP level. Conclusions ACS patients with high hsCRP levels had more fibrocalcific plaque and longer lesion than those with low hsCRP levels. The association between high hsCRP levels and vulnerable characteristics of culprit plaque was not demonstrated. Funding Acknowledgement Type of funding source: None
