ABSTRACT
@#BACKGROUND: Previous studies have reported inconsistent findings regarding the association between catestatin and outcomes of acute myocardial infarction (AMI). This study aims to investigate the prognostic value of catestatin for long-term outcomes in patients with AMI. METHODS: One hundred and sixty-five patients with AMI were enrolled in this series. The plasma catestatin levels at baseline and clinical data were collected. All patients were followed up for four years to investigate whether there were major adverse cardiovascular events (MACEs), including cardiovascular death, recurrent AMI, rehospitalization for heart failure, and revascularization. RESULTS: There were 24 patients who had MACEs during the follow-up period. The MACEs group had significantly lower plasma catestatin levels (0.74±0.49 ng/mL vs. 1.10±0.79 ng/mL, P=0.033) and were older (59.0±11.4 years old vs. 53.2±12.8 years old, P=0.036). The rate of MACEs was significantly higher in the elderly group (≥60 years old) than in the young group (<60 years old) (23.8% [15/63] vs. 8.8% [9/102], P=0.008). The catestatin level was significantly lower in the MACEs group than that in the non-MACEs group (0.76±0.50 ng/mL vs. 1.31±0.77 ng/mL, P=0.012), and catestatin was significantly associated with MACEs (Kaplan Meier, P=0.007) among the elderly group, but not in the young group (Kaplan Meier, P=0.893). In the Cox proportional hazards regression, high catestatin was one of the independent factors for predicting MACEs after adjustment for other risk factors (hazard ratio 0.19, 95% confidence interval 0.06-0.62, P=0.006) among elderly patients. CONCLUSIONS: Elderly AMI patients with lower plasma catestatin levels are more likely to develop MACEs. Catestatin may be a novel marker for the long-term prognosis of AMI, especially in elderly patients.
ABSTRACT
Objective:To measure serum levels of salusins and catestatin and analyze their correlation in patients with essential hypertension (EH) .Methods :A total of 90 EH patients were selected as hypertension group .According to blood pressure level ,they were further divided into hypertension stage 1 group (n=31) ,hypertension stage 2 group (n=30) and hypertension stage 3 group (n=29) .Another 40 normotensive subjects undergoing physical examina‐tion were selected as normal control group .Enzyme linked immunosorbent assay (ELISA) was used to measure ser‐um levels of salusins and catestatin , and the correlation between serum levels of salusins and catestatin was analyzed . Results :Compared with normal control group ,there were significant reductions in serum levels of salusins [ (3.01 ± 0.66) ng/ml vs .(1.44 ± 0.42) ng/ml ,(1.35 ± 0.89) ng/ml ,(1.41 ± 0.32) ng/ml] and catestatin [(132.24 ± 7.55) ng/ml vs .(89.22 ± 6.12) ng/ml vs .(82.51 ± 8.37) ng/ml ,(83.34 ± 4.47) ng/ml] in hypertension stage 1 ,stage 2 and stage 3 group , P0.05 all) .Pearson correlation analysis indicated that serum salusins level had no correlation with catestatin level ( r=0.363 , P>0.05) in normal control group ,while serum salusins level was significant positively correlated with catestatin level (r=0.723 ,P<0.01) in hypertension group .Conclusion:Serum levels of salusins and catestatin significantly reduce and they is positive correlation in patients with hyperten‐sion .Along with blood pressure level rises ,serum catestatin level reduces .
ABSTRACT
Objective: To analyze plasma levels of catestatin (CST) in patients with different blood pressure (BP) and metabolic status. Methods: Our research included in 3 groups: Control group,n=60 subjects with normal BP from physical examination in our hospital; 131 patients with essential hypertension (EH) were divided into 2 groups: Isolated EH group,n=90 and MS (metabolic syndrome) group,n=41. Plasma levels of CST, norepinephrine (NE) were examined, the ratio of CST/NE was calculated, and those indexes were compared among different groups. Results: Compared with Control group, plasma levels of CST and the ratios of CST/NE were decreased in Isolated EH and MS groups,P Conclusion: Plasma levels of CST and the ratio of CST/NE were obviously decreased in EH patients, CST was even lower in MS patients which implied that CST might be involved in the development of EH and MS.
ABSTRACT
Objective:To explore changes of plasma levels of catestatin (CST)and brain natriuretic peptide (BNP)in patients with chronic heart failure (CHF)and their correlation.Methods:A total of 60 CHF patients treated in our department of cardiology from Jun 2014 to Dec 2014 were enrolled as CHF group,another 60 healthy subjects un- dergoing physical examination were regarded as normal control group.Enzyme linked immunosorbent assay was used to measure plasma levels of CST and BNP in two groups,then the results were compared.Linear correlation analysis was used to analyze the correlation between plasma levels of CST and BNP.Results:Compared with normal control group,there were significant rise in plasma levels of CST [(0.40±0.15)ng/L vs.(0.88±0.34)ng/L]and BNP [(30.84±12.56)ng/L vs.(678.21±120.35)ng/L]in CHF group,P<0.01 both.Linear correlation analysis indi- cated that plasma CST level was significant positively correlated with BNP level (r=0.38,P<0.05).Conclusion:Catestatin level is significant positively correlated with the most sensitive cardiac function index—brain natriuretic peptide level,suggesting that it could be used as a new biochemical marker diagnosing or excluding heart failure.
ABSTRACT
Objective To explore the predictive value of plasma catestatin (CST ) and its influence factors for prognosis of patients with chronic systolic heart failure .Methods In a retrospective study ,the clinical data of 352 chronic systolic heart failure patients were collected from our hospital 2009 to 2013 .The patients were categorized into 4 groups (n= 88) according to CST (ng/L) quartile :≤ 60 .24 ,60 .25 - 76 .57 ,76 .58 - 86 .33 and ≥ 86 .34 ng/L .Blood pressure ,heart function ,blood biochemical index and renal function were compared among groups as well as the correlation with CST by Spearman correlation .According to the survival situation of follow‐up ,the patients were assigned into death and survival groups .The predictive value of CST for the prognosis of chronic systolic heart failure patients were analyzed by univariate and multivariate Cox survival analysis .Results Age ,sex ,body mass index ,red blood cell count ,red blood cell volume ,hemoglobin ,albumin ,total bilirubin ,serum creatinine ,blood urea nitrogen ,u‐ric acid and pathogeny among 4 groups had no statistical significance (P> 0 .05) .Patients with higher CST levels were more likely to had higher NYHA classification ,systolic pressure ,diastolic pressure ,high sensitivity C‐reactive protein (hs‐CRP) ,plasma N‐ter‐minal proBNP (NT‐proBNP ) ,left ventricular end‐diastolic diameter (LVEDD ) and right ventricular end‐diastolic diameter (RVEDD) ,and had a lower left ventricular ejection fraction (LVEF) (all P< 0 .05) .The CST was positively correlated with hs‐CRP ,NT‐proBNP ,LVEDD and RVEDD (r = 0 .452 ,0 .571 ,0 .536 ,0 .473) and negatively correlated with LVEF (r = - 0 .357) . Taken CST ≤ 60 .24 ng/L for reference ,the risks of death for groups of 60 .25 - 76 .57 ,76 .58 - 86 .33 and ≥ 86 .34 ng/L increased by 1 .471 ,1 .767 and 7 .822 ,respectively .The Cox survival analysis showed that NYHA classification ,LVEF ,cardiac arrhythmia , atrial enlargement ,heart failure history and CST were independent prognostic factors .Conclusion The mortality of patients with chronic systolic heart failure was associated with plasma CST .Elevated CST increased total mortality risk and were independent prognostic factors of these patients ,but the evaluation of the prognostic value of CST etiology factors should be considered .
