AIM OF THE STUDY: Investigate the effect of Rosuvastatin on serum level of Vaspin and Visfatin in patients with CAD and determine the association between those adipokines and the severity of CAD.
BACKGROUND: Statin treatment is considered one of the most effective strategies for the stabilization of atherosclerotic plaques and is related with enhancements in result in patients with coronary course diseases (CAD). Vaspin and Visfatin are adipokines involved in atherosclerosis progression. Objective: assess the impact of Rosuvastatin on serum level of Vaspin and Visfatin in patients with CAD and the relationship of those adipokines with seriousness of CAD.
SETTING: Cardiology department, Tanta University Hospital, Egypt. METHODS: 80 patients who underwent coronary angiography due to symptoms of stable angina were enrolled in the study. 40 patients received Rosuvastatin 20 mg/day was compared to another 40 patients, as a control group, who refused statin treatment and preferred lifestyle modifications intervention. Main outcome measure: Clinical parameters, lipid profile, troponin I, high-sensitivity C-reactive protein (hs-CRP), Vaspin and Visfatin levels were assayed at the beginning and after 3 months. CAD severity was assessed by the Gensini score.
RESULTS: Rosuvastatin administration considerably ameliorated most lipid parameters. Moreover, a significant increase of Vaspin and decrease of Visfatin concentrations (p<0.001) after Rosuvastatin treatment were observed (from 2.81 ± 0.74 ng/ml to 4.26 ± 0.76 ng/ml, from 4.62 ± 0.76 to 3.13 ± 0.98 respectively). There was a negative correlation between Vaspin and the Gensini score and positive correlation between Visfatin and Gensini score (r=-0.18 and r=0.19, p=0.05, respectively).
CONCLUSION: Rousvastatin treatment reduces serum visfatin and increase serum vaspin levels in CAD patients. Those effects of Rousvastatin are of clinical importance.

Coronary heart disease (CHD) is the prominent cause of death worldwide and the main reason for coronary artery disease, cardiovascular diseases, and stroke is hypercholesterolemia . Statins are the most broadly utilized cholesterol-lowering agents. They reduce lipid levels in patients with dyslipidemia, cardiovascular disease and atherosclerosis, furthermore decrease morbidity and mortality [2,3]. Over the previous few years’ lipidindependent actions are attributed to this class of drugs progressing their antiatherosclerotic role further than lipid lowering i.e., pleiotropic – mechanisms . The question is whether or not the pleiotropic anti-inflammatory effects of statins are due to the modification of serum adipokines or not. In this perspective, contradictory results have been shown by previous studies that tested the effects of statins on adipokines . Visfatin is an adipokine which mostly found in visceral adipose tissue . Visfatin, has role in plaque destabilization, the promotion of angiogenesis, and glucose homeostasis, so it may have a role in atherosclerosis and coronary artery disease [7,8]. Visfatin seems to be a direct contributor to vascular inflammation and a distinctive attribute of atherothrombotic diseases linked to metabolic disorders . Vaspin is another member of adipokines which eventually identified in visceral white adipose tissues . It has anti-inflammatory and anti-apoptotic effects on vascular cells as well as improving insulin resistance. Vaspin could impede inflammatory factor secretion from vascular smooth muscle cells and counteract endothelial cell apoptosis induced by free fatty acid . Rosuvastatin is a commonly used HMGCoA reductase inhibitor (statin) and is used to improve lipid profiles in patients with coronary artery diseases .
Patient population and study design
A non-randomized controlled, prospective study conducted on 80 Patients (Figure 1), who underwent coronary angiography due to symptoms of stable angina at Cardiology department, Faculty of Medicine, Tanta University Hospital from January 2017 to January 2018. Stable angina defined as the presence of chest pain that did not change its pattern during the preceding 2 months.
For all patients, cardiovascular history was taken, complete physical examination was performed. Electrocardiogram and echocardiography were done then any abnormalities were recorded. Patients with a history of acute coronary syndrome within the past 6 months, severe chronic heart failure (NYHA class III–IV), cardiomyopathy, diabetes mellitus, morbid obesity (BMI >35), history of revascularization, malignant disease, major trauma or surgery, renal insufficiency (creatinine >2 mg/dl), liver impairment (ALT >2 times upper normal limit), acute or chronic infectious disease, or any kind of immune-mediated disease were excluded from the study. According to the study design 61 patients completed the study. 31 patients received Rosuvastatin 20 mg/d for three months was compared to 30 patients who refused to take statin medications, and preferred lifestyle modifications intervention (i.e., adherence to a heart-healthy diet, regular exercise habits, avoidance of tobacco products, and maintenance of a healthy weight). Both patient groups were homogeneous and followed up for three months.
After an overnight fasting, 10 ml venous blood samples were withdrawn from the antecubital vein under complete aseptic condition before coronary angiography. The collected blood samples were centrifuged then the separated serums were stored at -80º C until measurement of biochemical parameters. Serum Vaspin and Visfatin were measured by an ELISA kit for quantitative determination (GLORY Science, USA). Total cholesterol, triglyceride, high density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) were assessed by the enzymatic colorimetric method using Roche/Hitachi/911 automated Clinical Chemistry Analyzer. The Kit manufactured by Roche Diagnostics gmbh, D-68298 Mannheim, USA. The serum Troponin-I was assayed using ELISA kit (Biocheck, IncFoster CityCalifornia). Highly Sensitive-C-Reactive Protein was determined by ELIZA method [Labor Diagnostika Nord-Nordhorn-Germany] kits. Routine determination of random blood glucose and creatinine level was performed.
Diagnostic coronary angiography was done to all patients through either femoral or radial approach. Gensini score was used to assess the severity of CAD by an experienced cardiologist, unaware of the biochemical results of the patients. Gensini score was calculated through multiplication of score used for grading the luminal narrowing of the main coronary artery by a factor which was take into account the site and importance of the lesion. The score of luminal narrowing was 1 for ≤ 25% stenosis, 2 for 26-50% stenosis, 4 for 51-75% stenosis, and 8 for 76-90% stenosis, 16 for 91-99% stenosis and 32 for total occlusion. The factor of location was 5 for left main, 2.5 for the proximal lesion of either LAD (left anterior descending) or LCX (left circus flex), 1.5 for mid lesion, 1 for distal LAD, mid-distal LCX or RCA (right coronary artery). Then the sum of scores of all coronary arteries was used to express the total Gensini score .
Variables were presented as mean ± SD. Comparisons between two groups were carried out using an independent sample t-test. Correlation analysis using the Pearson coefficient of correlation was performed. p-value< 0.05 will consider significant. SPSS for windows software was used for statistical analysis (Version 22, SPSS Inc., Chicago, IL, USA).

The two groups had similar baseline characteristics, including gender, age, body mass index, systolic and diastolic blood pressure, lipid profiles, Troponin I, hs-CRP, Vaspin levels, Visfatin level and Gensini score (p>0.05). Results revealed that serum Vaspin level increased significantly after 3 months of treatment with a significant difference when comparing control group to Rosuvastatin group. On the other hand, serum Visfatin concentrations significantly decreased after 3 months of treatment when comparing the control patients to the patients received Rosuvastatin treatment.
Serum hs-CRP, Troponin I levels, TCH, LDL and TG levels were significantly decreased in patients who received Rosuvastatin treatment compared with control group, with a significant difference when comparing control and treated groups. Serum HDL level exhibited insignificant increase in both groups. The mean angiographic Gensini scores significantly decreased in patients received Rosuvastatin treatment compared with control group (Table 2).

TABLE 3: Correlation between measured Vaspin, Visfatin, lipid profile, Troponin I, hs-CRP and Gensini score parameters in Rosuvastatin group (n=31) and control group (n=30)
The present study showed that treatment with Rosuvastatin increased Vaspin serum levels in patients compared to control groups. In agreement with a recent study stated that Rosuvastatin significantly increases vaspin serum levels in acute coronary syndrome . On the other hand, a reduced Visfatin serum levels were observed in patients treated with Rosuvastatin compared to control groups. Consistence with a meta-analysis found that visfatin levels slightly reduced after statin therapy .
Furthermore, the present results showed a negative correlation of Vaspin with severity of CAD which assessed using Gensini score. In agreement with the present results, Kadoglou et al.  revealed a decreased Vaspin serum levels in asymptomatic patients with CAD compared with healthy control subjects. Moreover, they observed that low circulating vaspin concentrations were significantly correlated with CAD severity. In addition, Kobat et al.  found that, serum Vaspin levels significantly lower in patients with CAD consistently with our result. So, it may be used as a prognosticator of this disease However, they did not define the correlation of Vaspin and its relation to the severity of CAD. Moreover, Li et al.  studied the association of Vaspin gene polymorphisms with CAD in Chinese population. Their results showed that the serum Vaspin levels and risk for CAD. On the other hand, Aust et al.  could not found any relation between serum Vaspin levels and severity of atherosclerosis but they demonstrated that lower Vaspin serum levels had correlation with recent ischemic events in patients with carotid artery stenosis. Accordingly, they assumed that this biomarker may have a protecting role in patients with CAD. On the other hand, our results revealed a significant positive correlation between Visfatin serum levels with severity of CAD which assessed using Gensini score. In agreement with our result, Fu et al.  found a significant positive correlation between plasma Visfatin level and coronary lesion severity score. They concluded that there is a link between Visfatin level and the pathogenesis of CAD, so the detection of this adipokine might be useful for early diagnosis of CAD. In addition, Liu et al.  found that, plasma Visfatin levels were significantly higher in chronic CAD and acute coronary syndromes compared with control patients. The present study also found a significance decrease in total cholesterol and triglyceride LDL-cholesterol levels in patients received Rosuvastatin for three months compared to control group. In agreement with a recent study stated that treatment with Rosuvastatin displays a high efficacy in the improvement of lipid profile, and its pleiotropic effects (anti-inflammatory, antioxidant and antithrombotic), represents a fundamental role for cardiovascular primary and secondary prevention .
The present study revealed that Rosuvastatin therapy significantly decrease the serum level of hs-CPR level compared with control. This effect could be associated with the ability of statins to block pro-inflammatory transduction pathways . Pervious study assessed the effect of statin on inflammatory markers in chronic heart failure patients demonstrated that significant decrease in hsCPR level was associated with statin therapy [13,23]. The present study found a significant negative correlation between hsCPR serum levels with Vaspin serum levels. Consistently, Seeger et al.  found a negative relationship between Vaspin and CRP in patients on chronic hemodialysis and Kadoglou et al.  found an independent association of reduced Vaspin with increased hs-CRP and Visfatin levels suggesting a protective mechanism. Previous studies also, have indicated that CRP is an independent risk factor for atherosclerotic cardiovascular disease .
The present study also revealed that serum TroponinI levels, as indicator of myocyte injury, were decreased after Rosuvastatin treatment but insignificant difference was found when compared Rosuvastatin group with control group (p=0.07). Consistently, Everett et al., found no difference in high-sensitivity cardiac troponin I concentrations after Rosuvastatin 20 mg/d or control . Conversely, with the present results a recent study conducted on rats by Zhou et al.  showed that Rosuvastatin (5 mg/kg) significantly reduced the increased serum content of cardiac troponin I. The present study showed that Rosuvastatin treatment reduce serum Visfatin levels and increase serum Vaspin level, that may represent an anti-atherogenic property of the drug, which is independent of its lipid-lowering capability.
Rousvastatin treatment rather than lifestyle modification reduce serum visfatin and increase serum vaspin levels in CAD patients. Those pleiotropicassociated effects of Rousvastatin are of clinical importance. Moreover, low vaspin and high visfatin levels were significantly correlated with CAD severity suggesting a relation between atherosclerosis and adiposity.
