ABSTRACT
Objective To investigate the association between epicedial adipose thickness (EAT)and coronary artery in-stent restenosis (ISR).Methods 617 patients underwent review of coronary angiography in one year of drug-eluting stent implantation in our hospital from October 2013 to October 2015 were enrolled in the study.According to the angiography resluts,patients were divided into ISR group and control group.All cases recieved ultrasonic analysis of epicardial adipose thickness and biochemical test.The correlation of EAT,biochemical concentrations and ISR were determined.Results The EAT in ISR group was significantly higher than that in the control group [(7.78 ± 1.32) mm vs (4.19 ± 0.57) mm,t =22.998,P ＜ 0.001].It was also found that the family history of premature coronary artery disease and the severity of coronary artery lessions based on Syntax scores in the IRS group were higher than those in normal control group.Biochemical tests showed that plasma levels of triglycerides and glycosylated hemoglobin were higher,including plasma homocysteine and hypersensitive C-reactive protein (P ＜ 0.05).Multivariates logistic regression analysis suggested that the EAT was associated with ISR [Exp(B) =0.001,P =0.004].Moreover,one-way linear regression showed that EAT was correlated with the severity of IRS (r =0.891,P ＜0.001).Conclusions Epicardial adipose thickness was correlated with the occurrence and severity of coronary artery in-stent restenosis.
ABSTRACT
Objective To investigate the association between epicardial adipose thickness(EAT)and coronary artery plaque vulnerability evaluated by intravascular ultrasound(IVUS)in patients with coronary heart disease.Methods A retrospective case-control study was conducted.A total of 261 patients who were diagnosed with coronary heart disease via coronary angiography from August 2014 to March 2017 were enrolled in this study.Patients were divided into an acute coronary syndrome(ACS)group(n=92)and a stable angina pectoris(SAP)group(n=169).EAT and coronary artery plaque vulnerability evaluated by IVUS were compared between the two groups.The correlation between EAT and coronary artery plaque vulnerability was analyzed.Results EAT was greater in the ACS group than in the SAP group(5.4 ± 1.1)mm vs.(2.9±0.7) mm,t =12.664,P＜0.01).The plaque burden,the rates of soft plaque detection and the rates of spotty calcification detection were higher in the ACS group than in the SAP group(67.8±8.0)％ vs.(57.4 ± 10.4) ％,35.9％ or 33/92 vs.18.9％ or 32/169,0.4 ％ or 28/92 vs.17.8％ or 30/169,all P ＜0.05),while there was no significant difference in luminal area between the two groups(P =0.772).The proportion of positive remodeling was higher in the ACS group than in the SAP group(35.9％ or 33/92 vs.8.3％ or 14/169,P＜0.01).Linear regression analysis showed that EAT was correlated with plaque burden(r =0.592,P ＜0.01),lumen area(r =-0.273,P ＜0.01) and reconstruction index(r =0.447,P ＜0.01).Conclusions Epicardial adipose thickness is correlated to coronary artery plaque vulnerability evaluated by IVUS.
ABSTRACT
Objective To study the mechanism of lentinum's promotion on carvedilol's effects on dilated cardiomyopathy's heart function.Methods SD rat model of dilated cardiomyopathy was established with doxorubicin hydrochloride.The rat model was divided into blank control group,carvedilol group,lentinan group,carvedilol + lentinan group.Rats in the blank control group were given 2 mL of 0.9％ sodium chloride solution.Rats in the carvedilol group were given 10 mg·kg-1of carvedilol and 2 mL of 0.9％ sodium chloride solution.Rats in the lentinan group were given 1 mg·kg-1 of lentinan,and 2 mL of 0.9％ sodium chloride solution.Rats in the carvedilol + lentinan group were given10 mg· kg-1 of carvedilol,1 rmg·kg-1 of lentinan,and 2 mL of 0.9％ sodium chloride solution.The heart function,irrflammatory factors and T lymphocytes were compared.Results The left ventricular ejection fraction (LVEF) in carvedilol + lentinan group and carvedilol group were significantly higher than that in blank control group and lentinan group (P ＜ 0.05),while Tei index was significantly lower (P ＜ 0.05).The LVEF in carvedilol + lentinan group was significantly higher than that in carvedilol group (P ＜0.05),while Tei index was significantly lower (P ＜0.05).The hs-CRP,TNF-α,II-6 and IL-8 in carvedilol + lentinan group and lentinan group were significantly lower than that in blank control group and carvedilol group (P ＜0.05),while IL-10,CD3+,CD4+ and CD8+ were significantly higher (P ＜ 0.05).The hs-CRP,TNF-α,II-6 and IL-8 in C + L group were significantly lower than in lentinan group (P ＜ 0.05),while IL-10,CD3+,CD4+ and CD8+ were significantly higher (P ＜ 0.05).Conclusion Lentinan could significantly promote carvedilol's effects on dilated cardiomyopathy's heart function through lowering down inflammatory factors and increasing T lymphocytes.
ABSTRACT
BackgroundRevascularization and statin therapy are routinely used in the management of stable coronary artery disease. However, it is unclear whether the estimated high-density lipoprotein (HDL) particle size (eHDL-S), the ratio of HDL cholesterol (HDL-C) to apoprotein A-I (apoA-I), is associated with the clinical outcomes of diabetic patients with stablecoronary artery disease (CAD).MethodsWe per-formed a prospective cohort study of 328 patients diagnosed with stable CAD by coronary angiography. Patients were followed up for a mean duration of 12 months. The patients were divided into three groups by the tertiles of eHDL-S: low eHDL-S ( 0.79,n= 99). The associations between the baseline eHDL-S and short-term out-comes were evaluated using the Kaplan-Meier method and Cox proportional regression.Results The low eHDL-S group had higher trig-lyceride, hemoglobin A1c, uric acid, and leukocyte count than the other groups. During the follow-up period, 47/328 patients experienced a pre-specified outcome. According to the Kaplan-Meier analysis, the incidence of pre-specified outcomes was lower in the high eHDL-S group (P = 0.04). However, eHDL-S was not independently associated with adverse outcomes in Cox proportional hazards regression (haz-ard ratio (HR): 0.23, 95% confidence interval (95% CI): 0.01-11.24,P = 0.493).ConclusionAlthough the eHDL-S was associated with inflammatory biomarkers, it was not independently associated with the short-term prognosis of diabetic patients with stable CAD in the era of revascularization and potent statin therapy.
ABSTRACT
<p><b>BACKGROUND</b>Small case series have suggested an association of coronary myocardial bridge (MB) with myocardial infarction (MI). However, the relationship between MB and major adverse cardiac events (MACE) remains largely unknown. The aim of this study was to assess the relationship between MB and MACE involving MI.</p><p><b>METHODS</b>We performed a systematic search of MEDLINE, PreMEDLINE, and all EMB Reviews as well as a reference list of relevant articles according to the SPICO (Study design, Patient, Intervention, Control-intervention, and Outcome) criteria using the following keywords: myocardial bridging, myocardial bridge, intramural coronary artery, mural coronary artery, tunneled coronary artery, coronary artery overbridging, etc. Bibliographies of the retrieved publications were additionally hand searched. Studies were included for the meta-analysis if they satisfied the following criteria: (1) they evaluate the association of MB with cardiovascular endpoint event; (2) they included individuals with MB and those without MB; 3) they excluded individuals with obstructive coronary artery disease (CAD). Studies were reviewed by a predetermined protocol including quality assessment. Dates were pooled using a random effect model.</p><p><b>RESULTS</b>Seven observational studies that followed 5 486 patients eligible for the enrolled criteria were included from 7 136 initially identified articles. The prevalence of MB was 24.8% (1 363/5 486). During 0.5-7.0 years of follow-up of this cohort of population, crude outcome rates were 8.0% in the MB group and 7.7% in the non-MB group. The odds ratio of overall MACE and MI were 1.34 (95% confidence interval (CI): 0.57-3.17, P = 0.51, n = 7 studies) and 2.75 (95% CI: 1.08-7.02, P < 0.03, n = 5 studies) respectively for subjects of MB compared to non-MB.</p><p><b>CONCLUSION</b>Relationship between MB and MI appears to be a real one, although the study did not reveal a connection of MB to MACE, suggesting whether the necessity of antiplatelet therapy needs to be further studied in a larger cohort of patients with MB prospectively.</p>
