Abstract
The clinical efficacy of chemotherapy, as a recognized therapeutic approach for malignant diseases, usually has certain limitations due to its cardiotoxicity (CT) and consequent cardiomyopathy, or even heart failure. CT is defined as any cardiac injury connected with oncology treatment, whether it is chemo-, radio-, targeted or immunotherapy, or cancer by itself, and it represents a great challenge for clinicians in everyday practice. A wide spectrum of factors related to chemotherapy (type of drug, dose during each cycle, cumulative dose, schedule, method of application, combination with other cardiotoxic drugs or association with radiotherapy) and patient characteristics (age, presence of cardiovascular risk factors, previous cardiovascular disease) are the determining factors that influence the frequency of CT. Imaging methods for morphological and functional monitoring of the heart muscle are used for monitoring CT. The quest for diagnostic tools for early CT detection is of great significance. In line with this, the measurement of some cardiac biomarkers has found its place in clinical settings as an early determinant of myocardial injury. Therefore, in this review article, special attention will be paid to certain well-established, as well as certain novel cardiac biomarkers, and their role in recognizing asymptomatic CT, in order to gain deeper insight into their diagnostic utility.

Abstract
Background Circulating proteins are exposed to vascular endothelial layer and influence their functions. Among them, adipsin is a member of the trypsin family of peptidases and is mainly secreted from adipocytes, monocytes, and macrophages, catalyzing the rate‐limiting step of the alternative complement pathway. However, its pathophysiological role in cardiovascular disease remains to be elucidated. Here, we examined whether serum adipsin levels have a prognostic impact in patients with coronary artery disease. Methods and Results In 370 consecutive patients undergoing diagnostic coronary angiography, we performed a cytokine array analysis for screening serum levels of 50 cytokines/chemokines and growth factors. Among them, classification and regression analysis identified adipsin as the best biomarker for prediction of their long‐term prognosis (median 71 months; interquartile range, 55–81 months). Kaplan–Meier curve showed that higher adipsin levels (≥400 ng/mL) were significantly associated with all‐cause death (hazard ratio [HR], 4.2; 95% CI, 1.7–10.6 [P<0.001]) and rehospitalization (HR, 2.4; 95% CI, 1.7–3.5 [P<0.001]). Interestingly, higher high‐sensitivity C‐reactive protein levels (≥1 mg/L) were significantly correlated with all‐cause death (HR, 3.2; 95% CI, 1.7–5.9 [P<0.001]) and rehospitalization (HR, 1.5, 95% CI, 1.1–1.9 [P<0.01]). Importantly, the combination of adipsin (≥400 ng/mL) and high‐sensitivity C‐reactive protein (≥1 mg/L) was more significantly associated with all‐cause death (HR, 21.0; 95% CI, 2.9–154.1 [P<0.001]). Finally, the receiver operating characteristic curve demonstrated that serum adipsin levels predict the death caused by acute myocardial infarction in patients with coronary artery disease (C‐statistic, 0.847). Conclusions These results indicate that adipsin is a novel biomarker that predicts all‐cause death and rehospitalization in patients with coronary artery disease, demonstrating the novel aspects of the alternative complementary system in the pathogenesis of coronary artery disease.

Prognostic Impacts of Plasma Levels of Cyclophilin A in Patients With Coronary Artery Disease. Arterioscler Thromb Vasc Biol 2017; 37:685-693.

Abstract
Objective—
Cyclophilin A (CyPA) is secreted from vascular smooth muscle cells, inflammatory cells, and activated platelets in response to oxidative stress. We have recently demonstrated that plasma CyPA level is a novel biomarker for diagnosing coronary artery disease. However, it remains to be elucidated whether plasma CyPA levels also have a prognostic impact in such patients.
Approach and Results—
In 511 consecutive patients undergoing diagnostic coronary angiography, we measured the plasma levels of CyPA, high-sensitivity C-reactive protein (hsCRP), and brain natriuretic peptide and evaluated their prognostic impacts during the follow-up (42 months, interquartile range: 25–55 months). Higher CyPA levels (≥12 ng/mL) were significantly associated with all-cause death, rehospitalization, and coronary revascularization. Higher hsCRP levels (≥1 mg/L) were also significantly correlated with the primary end point and all-cause death, but not with rehospitalization or coronary revascularization. Similarly, higher brain natriuretic peptide levels (≥100 pg/mL) were significantly associated with all-cause death and rehospitalization, but not with coronary revascularization. Importantly, the combination of CyPA (≥12 ng/mL) and hsCRP (≥1 mg/L) was more significantly associated with all-cause death (hazard ratio, 21.2; 95% confidence interval, 4.9–92.3,;
P
<0.001) than CyPA (≥12 ng/mL) or hsCRP (≥1 mg/L) alone.
Conclusions—
The results indicate that plasma CyPA levels can be used to predict all-cause death, rehospitalization, and coronary revascularization in patients with coronary artery disease and that when combined with other biomarkers (hsCRP and brain natriuretic peptide levels), the CyPA levels have further enhanced prognostic impacts in those patients.

Association of Serum Pentraxin-3 and High-Sensitivity C-Reactive Protein with the Extent of Coronary Stenosis in Patients Undergoing Coronary Angiography. J Med Biochem 2015; 34:440-449.

Abstract
Background We compared factors of inflammation – high sensitivity C-reactive protein (hsCRP) and pentraxin-3 (PTX3), and we explored their relationship with coronary artery disease (CAD). Also, we tested the usefulness of hsCRP and PTX3 in the risk assessment of coronary stenosis development and the diagnostic ability of these biomarkers to detect disease severity. Methods The study group consisted of 93 CAD patients undergoing coronary angiography. Patients were divided into CAD(0), representing subclinical stenosis, and CAD (1–3), representing significant stenosis in one, two or three vessels. Results We determined the concentration of lipid status parameters, hsCRP and PTX3. We found significantly lower PTX3 and hsCRP concentrations in CAD(0) than in CAD(1–3) group. Concentration of PTX3 showed an increasing trend with the increasing number of vessels affected. The area under ROC curve (AUC) for the combinations of hsCRP and PTX3 with lipid parameters had useful accuracy for detecting CAD(1–3) patients (AUC=0.770, p<0.001). Conclusion PTX3 is a promising independent diagnostic marker for identifying patients with CAD, and a useful indicator of disease progression. In all the analyses PTX3 showed better performance than hsCRP. A combination of PTX3, hsCRP with the lipid status parameters provides risk stratification of the development of coronary stenosis and better classification than their individual application.

Abstract
OBJECTIVES Epidemiological evidence concerning the role of iron, a lipid peroxidation catalyst, in atherosclerosis and coronary artery disease (CAD) is inconsistent. DESIGN AND METHODS Exploratory factor analysis was used to examine the potential clustering of variables known to be associated with CAD using data from 188 patients with angiographically-approved disease. The resulting factors were then tested for their association with serum ferritin and soluble transferrin receptor (sTfR) as indicators of body iron status. RESULTS Factor analysis resulted in a reduction of a variable number from the original 15 to 5 composite clusters. These factors were interpreted as (1) "proatherogenic factor" with positive loadings of TC, LDL-C, apoB and TG; (2) "inflammatory factor" with positive loadings of hsCRP, fibrinogen and MDA; (3) "antiatherogenic factor" with positive loadings of HDL-C and apoA-I; (4) "obesity factor" with positive loadings of weight and waist; and (5) "antioxidative status factor" with positive loadings of SOD and age and negative loading of superoxide anion. "Inflammatory", "obesity" and "antiatherogenic" factors predicted high ferritin values and the "proatherogenic factor" predicted high sTfR values. We compared the ability of the "proatherogenic factor" with that of a multivariable logistic model that included the "proatherogenic factor" and sTfR values in predicting significant stenosis in patients. The area under the ROC curve was 0.692 vs. 0.821, respectively. CONCLUSIONS "Inflammatory", "obesity", "antiatherogenic" and "proatherogenic" factors were associated with increased parameters of body iron status. The measurement of sTfR improves the prediction of CAD based on clustered cardiovascular risk factors.

Abstract
OBJECTIVES The study aimed to investigate the predictive value of the combination of high-sensitivity C-reactive protein (hs-CRP) and apolipoprotein B (apoB)/apoA-1 ratio for the outcomes of coronary angiography (CAG), echocardiography and oral glucose tolerance tests (OGTTs). DESIGN AND METHODS Hs-CRP, apoB, apoA-1, and the profiles of CAG, echocardiography and OGTTs as well as traditional risk factors were measured in 1757 cardiology patients. RESULTS Hs-CRP or apoB/apoA-1 ratio was significantly correlated with the presence and severity of angiographic profiles, the levels of left ventricular (LV) ejection fraction, LV mass and LV mass index, and the presence of abnormal glucose metabolism. The combination of hs-CRP and apoB/apoA-1 ratio had greater correlation with abnormal glucose metabolism than its individual components in patients with normal fasting glucose, and was an independent predictor for coronary artery disease. CONCLUSIONS The combination of hs-CRP and apoB/apoA-1 ratio may be a strong predictor for coronary artery disease and abnormal glucose metabolism.

Abstract
High-sensitivity C-reactive protein (hsCRP) has been demonstrated to play a causal role in atherosclerosis and to predict cardiovascular events in the general population. On the other hand, left ventricular (LV) hypertrophy and diastolic dysfunction assessed by echocardiography can also predict cardiovascular events in patients with cardiovascular risk factors. However, there are few data regarding the relationships among hsCRP, LV hypertrophy, and diastolic function. We examined the relationships among hsCRP, LV hypertrophy, and diastolic function in 185 patients (65±11 years), who had no overt heart disease, but had cardiovascular risk factors, including hypertension, diabetes, and dyslipidemia. Echocardiography was performed to measure the left ventricular mass index (LVMI) as a parameter of LV hypertrophy. LV diastolic function was assessed by the ratio (E/A) of early (E) and late (A) diastolic transmitral flows, early diastolic mitral annular velocity (E'), and the ratio (E/E') of E to E' using Doppler echocardiography. The hsCRP was correlated with LVMI (r=0.228, p=0.002), E' (r=-0.276, p<0.001), and E/E' (r=0.419, p<0.001). The E/E' as a parameter of LV diastolic function showed the closest correlation to hsCRP. These results indicate that elevated hsCRP reflects LV diastolic dysfunction rather than LV hypertrophy. We therefore suggest that hsCRP may be a marker of subclinical LV diastolic dysfunction in patients with cardiovascular risk factors.

Abstract
Prospective studies and clinical trials have shown that C-reactive protein (CRP) independently predicts the occurrence of cardiovascular events, even in individuals without hypercholesterolemia. We evaluated whether CRP can predict the severity of coronary artery stenosis in patients with lower low-density lipoprotein cholesterol (LDL-C) levels. A total of 418 patients with lower LDL-C (<3.37 mmol/L) who underwent coronary angiography were recruited. The median levels of CRP increased according to the number of stenotic vessels. Multivariable adjustment model indicated that CRP was associated with the severity of coronary artery disease (CAD) in the top to the bottom third comparison of CRP levels, yielding an odds ratio of 1.72 (95% confidence interval: 1.08-2.74); this trend was preserved after excluding the confounding effect of statin treatment. C-reactive protein may serve as a useful biomarker for improving the risk assessment and secondary prevention of CAD patients without hypercholesterolemia.

Abstract
OBJECTIVE Dyslipidemia is commonly seen in patients with end-stage renal disease (ESRD). This prospective study investigates whether small-sized high-density lipoprotein (HDL) particles alone or in combination with high sensitivity C-reactive protein (hsCRP) are independent determinants of ESRD mortality. DESIGN AND METHODS We performed 36 months follow-up study in 122 haemodialysis (HD) patients. HDL size and subclass distribution were determined by gradient gel electrophoresis. Baseline characteristics of the patients were evaluated for the prediction of mortality. RESULTS Cox regressions analysis showed that patients with small-sized HDL particles had 2.8-fold higher risk of lethal outcome (P<0.05). Concomitant presence of small-sized HDL particles and increased hsCRP concentration were significantly associated with reduced survival rate (HR=3.907; P<0.05). Observed relationships persisted after adjustment for serum lipid and lipoprotein concentrations. CONCLUSIONS Our results indicate that small-sized HDL particles alone and combined with elevated hsCRP concentrations are independent predictors of reduced survival in HD patients.

Abstract
Being the most common cause of death from poisoning worldwide, cardiovascular manifestations of acute carbon monoxide (CO) poisoning have been subject of various studies but current evidence about effects of chronic CO exposure on atherosclerosis is limited which is very common. We aimed to investigate association of chronic CO exposure with atherosclerosis by measuring carotid intima-media thickness (CIMT) and high-sensitivity C-reactive protein (hs-CRP). Forty healthy male non-smoker indoor barbecue workers (mean age; 33.0 +/- 9.0 years) working in different restaurants for at least three years and 48 age-matched healthy men (mean age; 34.3 +/- 6.6 years) enrolled in the study. Clinical characteristics of indoor barbecue workers and control group were comparable in terms of body mass index, blood pressure, and lipid profile. However, carboxyhemoglobin (COHb) (6.4 +/- 1.5% vs. 2.0 +/- 1.1%), hs-CRP (2.7 +/- 2.0 mg/L vs. 1.1 +/- 0.8 mg/L) and CIMT (1.1 +/- 0.3 mm vs. 0.9 +/- 0.1 mm) were higher in indoor barbecue workers (p < 0.001 for each). In Pearson correlation analysis, CIMT was correlated with COHb concentration (r = 0.635, p < 0.001) and hs-CRP level (r = 0.466, p < 0.001). Among indoor barbecue workers, the years worked (years exposed to CO) are correlated with COHb, hs-CRP and CIMT. In multivariate analysis, COHb concentration is the only independent predictor of CIMT (beta = 0.571, p < 0.001). The increased CIMT and hs-CRP in indoor barbecue workers suggest that chronic CO exposure may increase the risk of atherosclerotic cardiovascular events.

Abstract
Although results from in vitro studies and clinical trials demonstrate strong associations between oxidative stress and cardiovascular risk, to date still no convincing data are available to suggest that treatment with antioxidants might reduce vascular events. Oxidative modifications of low-density lipoproteins (LDL) represent an early stage of atherosclerosis, and small, dense LDL are more susceptible to oxidation than larger, more buoyant particles. Oxidized LDL are independent predictors of subclinical and clinical atherosclerosis. Recent studies suggested that novel therapeutic strategies may take into account the removal of such particles from circulation. Future research is required to explore the potential synergistic impact of markers of oxidative stress and atherogenic dyslipidemia, particularly small dense LDL, on cardiovascular risk.

Abstract
BACKGROUND Alterations in plasma lipoprotein subclass distribution affect the risk for coronary artery disease (CAD). However, it is unclear whether the determination of low-density lipoprotein (LDL) and high-density lipoprotein (HDL) phenotypes may or may not improve the ability to predict CAD development. METHODS Polyacrylamide gradient (3-31%) gel electrophoresis was used to simultaneously determine size and distribution of lipoprotein subclasses in 181 CAD patients and 178 controls. RESULTS Mean LDL and HDL subclass sizes were significantly smaller in patients than in controls (p < 0.001). Multivariate logistic regression analysis showed that small dense LDL particles were independent CAD risk predictors (OR = 2.867, p < 0.01), even when adjusted for other traditional risk factors, while small HDL particles lost their significance after adjustment (OR = 2.071, p = 0.054). The area under the ROC curve for LDL (0.671) and HDL (0.643) particle size measurement demonstrated low clinical accuracy when compared to the combination of traditional lipid risk factor measurements. CONCLUSIONS CAD is associated with the predominance of smaller LDL and HDL particles. However, simultaneous determination of these two lipoprotein phenotypes provides no additional power in discriminating CAD and non-CAD subjects, beyond that obtained by the traditional risk factors.

Abstract
Elevated serum uric acid (UA) is associated with higher risk for cardiovascular disease (CVD). Smaller, denser low density lipoprotein (LDL) and high-density lipoprotein (HDL) particles are the potential risk factors for CVD, while the role and diagnostic value of inflammatory markers are firmly established. This current cross-sectional study investigates interrelationships between UA, high sensitivity C-reactive protein (hsCRP) and fibrinogen concentrations with LDL and HDL sizes in healthy middle-aged subjects. The outcomes-of-interest were smaller, denser LDL and HDL particles (LDL size <or=25.5nm and HDL size <or=8.8nm). Serum UA, hsCRP and plasma fibrinogen concentrations were measured by standard laboratory methods in a sample of 194 healthy volunteers (112 men and 82 women). LDL and HDL particle sizes were determined by gradient gel electrophoresis. The subjects in the highest UA tertile had significantly smaller LDL and HDL particle sizes (P<0.05 and P<0.01, respectively) and higher concentrations of fibrinogen and hsCRP (P<0.05 and P<0.01, respectively). Elevated UA (>or=318micromol/L) was a significant predictor of smaller, denser LDL and HDL particles (OR=3.09; P<0.01; n=19 and OR=4.40; P<0.001; n=23, respectively). The observed relationship with smaller HDL size persisted after adjustment for conventional cardiovascular risk factors. UA strongly correlated with both markers of inflammation. In addition, the higher hsCRP level correlated with smaller LDL size (P<0.05), while fibrinogen concentration was inversely related to HDL size (P<0.05). Multiple regression analysis revealed that HDL size and inflammatory markers remained independent determinants of UA concentration. In conclusion, higher serum UA and low-grade inflammation are closely linked to alterations in lipoprotein metabolism which may represent an early sign of atherosclerosis in asymptomatic subjects.

Abstract
Epidemiological studies have shown that a high serum uric acid concentration is a risk factor for coronary artery disease (CAD). However, the issue of whether it is an independent cardiovascular risk factor or simply a marker of co-existing conditions is a matter of controversy. In the present case-controlled study, we explored the association between serum uric acid and angiographically defined CAD in middle-aged subjects (356 CAD patients and 350 healthy individuals). Serum uric acid in CAD patients was significantly higher than that in healthy individuals (359 +/- 88.7 and 289 +/- 79.3 micromol/l, respectively, p < 0.01) and remained significantly higher after adjusting for confounding factors (F = 79.77, p < 0.01). The association between uric acid and CAD was not limited to the hyperuricemic range of values, but was also found in the high-normal range (p < 0.01). An unadjusted odds ratio (OR) of 5.0 was obtained in both genders (p < 0.01). Female patients with > 50% stenosis (clinically significant CAD), regardless of the number of diseased vessels, had higher uric acid concentrations than those with < 50% stenosis even after adjusting for confounders (F = 3.79, p = 0.01). In conclusion, we have demonstrated that high serum uric acid is independently associated with CAD and that uric acid determination could be useful as one of the markers of clinically significant CAD.

Abstract
OBJECTIVES In addition to many traditional risk factors for coronary artery disease (CAD) development, enhanced oxidative stress and inflammation are serious conditions that may also be classified as novel risk factors. In the present study, we assessed the relationship between several parameters of oxidative stress status [malonaldehyde (MDA), superoxide anion (O(2)(-)) and plasma and erythrocyte superoxide dismutase (SOD) activities] with high sensitivity C-reactive protein (hsCRP) and fibrinogen as inflammation markers. DESIGN AND METHODS Oxidative stress status parameters, inflammation markers and lipid status parameters were measured in 385 subjects [188 coronary heart disease (CHD) patients with angiographically diagnosed coronary artery disease (CAD), 141 patients with occlusion >50% in at least one major coronary artery (CAD+) and 47 patients with occlusion less than 50% (CAD-), and 197 CHD-free middle-aged subjects (the control group)]. RESULTS The plasma MDA concentration and the level of O(2)(-) in plasma were significantly higher in combination with significantly lower SOD activity in the CAD+ group vs. the control group. By using multiple stepwise regression analysis, fibrinogen and hsCRP showed independent correlation with MDA. Binary logistic regression analysis indicated that both MDA and O(2)(-) were significantly associated with CAD development and adjustment for inflammatory markers weakened this association in the case of MDA. CONCLUSIONS The relationship between oxidative stress parameters and inflammatory species suggest their strong mutual involvement in atherosclerosis development that leads to CAD progression.
