ABSTRACT

Objective To study the correlation between the risk factors of coronary slow flow phenomenon ( CSF) and the level of plasma D-dimer in patients with ACS ( acute coronary syndrome) after emergency percutaneous coronary intervention ( PCI) .Methods A total of 297 patients with ACS after PCI were enrolled for retrospective analysis.All patients were divided into CSF group and control group in the light of corrected thrombolysis in myocardial infarction (TIMI) frame count method (cTFC).Multivariate analysis for evaluating clinical predictors of CSF was carried out using Logistic regression test and Pearson analysis to find the correlation between plasma D-dimer and cTFC.The predictive value of D-dimer level in the occurrence of coronary slow flow was determined by using receiver operating characteristic ( POC) curve analysis.Results CSF was observed in 59 cases (19.8%).The plasma D-dimer was significantly higher in the coronary slow flow group compared with the control group ( P <0.05 ) .Multivariate regression analysis and Logistic regression test showed that the level of plasma D-dimer ( OR =1.276, 95%CI:1.132-3.224, P=0.012), thrombus score (OR =1.108, 95%CI: 1.085-2.103, P =0.018) and target lesion length of culprit vessel ( OR =1.436, 95%CI: 0.635-1.382, P =0.037 ) were the risk factors of CSF.Correlation analysis showed that plasma D-dimer were positively associated with CSF. Receiver operating characteristic ( ROC ) curve analysis showed that D-dimer cutoff point at 515.3 ng/ml had a good judgment significance ( AUC 0.783, OR =1.502, 95%CI: 1.324-2.531, P =0.005). Conclusions The increased D-dimer level is a risk factor and plays an important role in the ACS patients with the CSF phenomenon, thereby predicting no-reflow phenomenon after primary PCI in these patients.

ABSTRACT

Objective: To evaluate the impact of anemia on prognosis of elder patients with acute coronary syndrome (ACS) after percutaneous coronary intervention (PCI). Methods: A total of 908 consecutive ACS patients elder than 60 years of age with PCI in our hospital from 2010-06 to 2012-06 were studied. According to WHO deifnition of anemia (HB Results: There were 31%of patients suffering from anemia. Anemia group had more patients with the elder age, female gender, diabetes, hypertension, chronic kidney disease, decreased LVEF, more patients with 3 vessel-disease, and higher mortality at 1 year after PCI, higher rate of MACCE than those in Non-anemia group, all P Conclusion: Anemia may increase the incidences of mortality and MACCE in elder ACS patients after PCI for a long-term.

ABSTRACT

Cardiac biomarkers of sensitive and specific are very important to the early diagnosis of cardiovascular diseases,such as cardiac troponin (high sensitivity),myoglobin,heart-fatty acid-binding protein,ischemia modified albumin,B-type natriuretic peptide and N-terminal-pro-B-type natriuretic peptide.They also play an important role in risk stratification and prognosis evaluation,but improvement is still needed.Biomarker of high sensitivity and specificity,convenient detection control is still required in clinical application.

ABSTRACT

Objective To investigate the relationship between 4G/5G polymorphism in the promotor of plasminogen activator inhibitor-1 (PAI-1) gene and pulmonary thromboembolism (PTE). And to detect whether it plays an important role in the pathogenesis of PTE. Methods The 76 patients with PTE, 74 gender and age matched healthy controls were recruited in this study. Genome DNA was extracted from whole blood using phenol-chloroform. Subjects were genotyped for the 4G/ 5G polymorphism of PAI-1 gene using polymerase chain reaction and restriction fragment length polymorphism analysis. Results Significant difference was found in the frequency of 4G/4G genotype between PTE group and control group (50.0% vs.24.3%,P<0.01). And there were no significant differences in 4G/5G and 5G/5G genotype between the two groups. The 4G allele frequency was higher in PTE group than in control group (72.4% vs. 55.4% , P<0.01) . The recessive allele model was informative and the odd ratio of 4G/4G genotype was much higher than of other two genotypes (OR=3.40, P<0.01). Further stratification showed 4G/4G genotype was associated with high risk of PTE for those individuals without traditional environment risk factors. Conclusions The 4G/5G polymorphism of PAI-1 gene is associated with PTE and 4G allele is recessive. 4G/4G genotype increases the risk of PTE for individuals who have no traditional risk factors of PTE.
