  • Research Progress on Diet and Heart Failure

    As the eventual end of the cardiovascular disease, heart failure is aggravated or results in cachexia when the patient is under malnutrition or exposes to certain risk factors of diet mode during the long disease duration. Researches reveal that the diet has effects on patho-physiology, energy metabolism, inflammation and oxidative stress of heart failure. This article conducts a literature review on the association between diet and heart failure.

  • Echocardiographic characteristics of aortic valve disease in different ethnic groups in Xinjiang

    ObjectiveTo explore the echocardiography characteristics of aortic valve disease (AVD) among different ethnic groups in Xinjiang.MethodsThe data of a large sample (n=130 358) of different ethnic groups in Xinjiang based on the results of echocardiography were analyzed between January 2011 and December 2016, and the echocardiography characteristics of AVD among the Han nationality and different ethnic minorities in Xinjiang were summarized.ResultsThe study recruited 130 358 patients, involving Han nationality (58.49%) and 33 ethnic minorities. The ethnic minorities included the Uygur (27.42%), Kazak (7.47%), Hui nationality (3.48%) and other minorities (3.13%). Apart from Uygur, Kazak and Hui nationality, no description was given due to the small sample sizes of other minorities (3.13%). In the total study population, the prevalence of aortic valve stenosis (AS) was 0.44%, and the prevalence of severe AS was 0.10%; the prevalence of aortic valve regurgitation (AR) was 0.37%, and the prevalence of severe AR was 0.02%; the prevalence of aortic valve calcification (AVC) was 6.51%, and the highest AVC prevalence existed in ≥75 years old age group (24.45%); the prevalence of bicuspid aortic valve (BAV) was 0.54%, and the highest BAV prevalence existed in 18-44 years old age group (0.86%). Among different ethnic groups, the Uygur had the highest prevalence in terms of AS (0.60%), AR (0.63%) and BAV (0.88%), while the Han had the lowest prevalence in terms of AS (0.37%) and AR (0.24%), but the highest AVC prevalence existed in the Han nationality (7.83%). The etiology of AVD showed that the degenerative valve changes was the main cause of AS with the largest proportion of 61.97%. While the aorta root diseases (35.97%) and BAV (22.87%) were the main etiology of AR.ConclusionsIn Xinjiang the overall prevalence of AVD is low. In the elderly population, the Uygur, Kazak and Hui nationality have the higher AS prevalence than the Han nationality does. Different ethnic groups have different AVD characteristics based on the echocardiography. In the Uygur group, AVD presents the younger age of onset; the prevalence of BAV is the highest in the Uygur population, while the lowest in the Hui nationality.

  • Association of Central Obesity and Carotid Intima-Media Thickness in Han, Uygur and Kazak Female Adults in Xinjiang

    Objective To investigate the association of central obesity (Waist-to-Hip Ratio) and carotid intima-media thickness (IMT) in Han, Uygur and Kazak female adults in Xinjiang. Methods Four-stage stratified cluster random sampling was used to select adult samples aged over 35 years in different districts in Xinjiang, and then a study was conducted using a questionnaire, physical exams (including blood pressure, height, weight, waist length, and hip length) and lab biochemical tests, while IMT was measured by ultrasound. According to WHR, the people were divided into two groups (WHR≥0.9 group and WHRlt;0.9 group). Results 14 618 cases had been surveyed, including 7 294 female adults (Han: 2 793 cases; Uygur: 2 490 cases; and Kazak: 2 011 cases). Among the same nationality, the WHR≥0.9 group had higher levels of systolic pressure, diastolic pressure, urea nitrogen, fasting blood-glucose, triglyceride and total cholesterol than the WHRlt;0.9 group, with significant differences (P=0.000). The two groups were the same in creatinine, high-density lipoprotein cholesterol and low density lipoprotein with no significant differences (Pgt;0.05). Among all people, the WHR≥0.9 group had slightly thicker IMT than the WHRlt;0.9 group (P=0.17). Among the Han nationality, the two groups were the same in IMT (P=0.23). Uygur’s IMT and Kazak’s IMT in the WHR≥0.9 group were thicker than that in the WHRlt;0.9 group (P=0.00). Among different populations, in the WHR≥0.9 group, Kazak’s IMT was the thickest, while Uygur’s IMT was the thinner, with significant differences (P=0.00). Within the WHR≥0.9 group, in different age groups, Kazak’s IMT was the thickest; except in the group of aged over 75 years, there were significant differences among other subgroups, the Han group, and the Uygur group (all Plt;0.05). The result of logistic regression showed that, WHR≥0.9 was an independent risk factor of IMT thickening among the three groups. Conclusion WHR increase is positively associated with IMT among the three nationalities. Also, WHR≥0.9 was an independent risk factor of IMT in all the three nationalities.

  • Efficacy and Safety of Trimetazidine for Stable Angina Pectoris: A Systematic Review

    Objective To evaluate the efficacy and safety of trimetazidine (TMZ) in the treatment of Stable Angina Pectoris (SAP). Methods Randomized controlled trials (RCTs) on the efficacy and safety of Trimetazidine in treating patients with SAP were retrieved in the following databases as CNKI (1997 to June 2011), WanFang Data (1989 to June 2011), MEDLINE (1966 to June 2011), EMbase (1974 to June 2011), CBM (1989 to June 2011) and Cochrane Central Database (1989 to June 2011). The literature which met the inclusion and exclusion criteria were selected, data were extracted, the quality was evaluated, and meta-analysis was performed by using RevMan 5.0 software. Results A total of 15 RCTs involving 1 500 patients were included. The meta-analysis showed that, compared with the control group, TMZ was significantly superior in the following 5 aspects: the time to 1 mm drop of ST segment (WMD=0.84, 95%CI 0.74 to 0.93, P=0.000 01), duration of doing exercise (WMD=0.82, 95%CI 0.73 to 0.91, P=0.000 01), and time to onset of angina (WMD=1.18, 95%CI 0.87 to 1.50, Plt;0.000 01) in the treadmill test, weekly mean number of angina attacks (WMD= –1.79, 95%CI –1.93 to –1.66, Plt;0.000 01), and weekly side effects between TMZ and the control group (RR=0.83, 95%CI 0.52 to 1.32, P=0.42). Conclusion Based on current studies, TMZ is superior to other medicines in the control group for SAP at present, and it has no significant difference in side effects compared with the control group, so it is regarded as an effective and safe drug. For the quality restrictions and possible publication bias of the included studies, this conclusion needs to be confirmed by more high quality, large sample, multi-center, double blind RCTs.

  • Effectiveness of Nicorandil for Reperfusion of Acute Myocardial Infarction: A Meta-Analysis

    Objective To evaluate the effectiveness of nicorandil for reperfusion of acute myocardial infarction (AMI), so as to provide high quality evidence for formulating the rational AMI therapy. Methods Databases including The Cochrane Library (Issue 3, 2012), PubMed, EMbase, HighWire, CBM, and CNKI were searched to collect randomized controlled trials (RCTs) on nicorandil in AMI reperfusion published before March 2012. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and evaluated the methodological quality of the included studies. Then the meta-analysis was conducted using RevMan5.1 software. Results A total of 11 trials involving 1 027 patients were included. The results of meta-analyses showed that: for AMI reperfusion, nicorandil could decrease the non-reflow or slow flow rate (RR=0.34, 95%CI 0.19 to 0.61, P=0.000 3), improve the left ventricular ejection fraction (MD=5.49, 95%CI 4.51 to 6.47, Plt;0.000 01), reduce the left ventricular end-diastolic volume (MD=–14.38, 95%CI –17.31 to –11.45, Plt;0.000 01), and decrease the incidence of cardiac adverse events (RR=0.34, 95%CI 0.25 to 0.46, Plt;0.000 01), readmission rate (RR=0.33, 95%CI 0.17 to 0.63, P=0.000 8) and mortality rate (RR=0.40, 95%CI 0.16 to 0.97, P=0.04). Conclusion Current evidence shows that nicorandil used as an adjuvant for AMI reperfusion can increase coronary microcirculation, improve prognosis, and decrease the incidence of cardiac adverse events, readmission and mortality rate. Due to the limited quality and quantity of the included studies, this conclusion still needs to be further proved by performing more large-scale and high quality RCTs, so we suggest clinician should adopt rational therapies based on patient’s conditions.

  • Optimal Duration of Dual Antiplatelet Therapy in Patients Undergoing Percutaneous Coronary Intervention: A Meta-Analysis

    Objective To assess the effectiveness and safety of different dual antiplatelet therapies in patients undergoing percutaneous coronary intervention. Methods Such databases as The Cochrane Library, MEDLINE, EMbase, CBM, CNKI and WanFang Data were searched to collect the randomized controlled trials (RCTs) and observational studies on the effectiveness and safety of dual antiplatelet therapies both short-duration (≤6 months) and long-duration (gt;6 months) after percutaneous coronary intervention. The literature was screened according to the inclusive and exclusive criteria by two reviewers independently, the quality was evaluated, the data were extracted, and meta-analyses were performed by using RevMan 5.1 software. Results Eight trials were included, of which 3 were RCTs involving 7 475 patients, and 5 were observational studies involving 12 744 patients. Meta-analyses on RCTs showed that the incidence of death or myocardial infarction in the long-duration treatment group was lower than that of the short-duration treatment group (OR=0.74, 95%CI 0.56 to 0.98, Plt;0.000 1), while meta-analyses on observation studies showed the similar result (OR=0.7, 95%CI 0.45 to 1.08, P=0.11). With the variables of published year and follow-up time, the heterogeneity of cohort studies was discussed through meta-regression (Z=3.61, P=0.000) which indicated that both published year and follow-up time might be the source of heterogeneity due to their contribution. For RCTs, the incidence of severe bleeding events in the short-duration treatment group was lower than that in the long-duration treatment group (OR=1.29, 95%CI 0.99 to 1.69, P=0.06). For observational studies, the incidence of late stent thrombosis in the long-duration treatment group was lower than that in the short-duration treatment group (OR=0.40, 95%CI 0.15 to 1.07, P=0.07). Conclusion The long duration (gt;6months) of dual antiplatelet therapy in patients undergoing percutaneous coronary intervention can reduce the incidence of death or myocardial infarction and decrease the tendency of late stent thrombosis, but cannot obviously increase the incidence rate of severe bleeding events. The current evidence shows no marked superiority in longer duration (gt;12months) of dual antiplatelet therapy.

  • Benefit of Early Invasive Therapy in Unstable Angina and Non-ST-Elevation Myocardial Infarction: A Systematic Review

    Objective To determine the benefits of an invasive compared to a conservative strategy for treating unstable anguba (UA)/ non-ST-elevation myocardial infarction (NSTEMI). Methods We searched The Cochrane Library (Issue 4, 2009), MEDLINE (1996 to September 2009), EMbase (1974 to September 2009), CBM (1989 to 2009), CNKI (1997 to 2009), and VIP (1989 to 2009). The quality of the included studies was critically evaluated. Data analyses were performed using the Cochrane Collaboration’s RevMan 5.0 software. Results Seven randomized controlled trials involving 11 394 patients met the inclusion criteria. The results meta-analyses showed the incidence of all-cause mortality at six months follow-up was lower in the early invasive group compared with the conservative group (RR=0.75, 95%CI 0.61 to 0.92, P=0.007); the relative risk of myocardial infarction was significantly decreased in the early invasive group (RR=0.74, 95%CI 0.63 to 0.87); there was a reduction in rehospitalization for unstable angina in the invasive group (RR=0.66, 95%CI 0.61 to 0.73, Plt;0.000 01); the invasive strategy was associated with a two-fold increase in the relative risk of PCI-related myocardial infarction (as variably defined). There was not a significant increase in bleeding by an invasive strategy at six months follow-up, but, a routine invasive strategy was associated with a significantly higher bleeding rate at 1-year follow-up (RR=2.22, 95%CI 1.55 to 3.17, Plt;0.000 1). Patients with elevated cardiac biomarker levels at baseline benefited more from routine intervention, with no significant benefit observed in patients with negative baseline marker levels. Conclusion An early invasive strategy is preferable to a conservative strategy in the treatment of UA/NSTEMI, especially higher-risk patients with elevated cardiac biomarker benefit more from invasive strategy. In addition, complications such as procedure-MI and bleeding must be paid great attention to.

  • Efficacy and safety of different duration of dual antiplatelet therapy in patients undergoing new-generation drug-eluting stents implantation: a meta-analysis

    Objective To systematically review the efficacy and safety of different duration of dual antiplatelet therapies in patients undergoing new-generation drug-eluting stents implantation. Methods Such databases as MEDLINE, The Cochrane Library (Issue 2, 2015), EMbase, CBM, CNKI and WanFang Data were searched to collect studies on the different duration of dual antiplatelet therapies in patients undergoing new-generation drug-eluting stents implantation from inception to April 2015. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed using RevMan 5.3 software. Results Six trials were included. The results of meta-analysis showed: compared with 12 months dual antiplatelet therapy group, the incidence of bleeding in the 6 months dual antiplatelet therapy group was lower (OR=0.48, 95%CI 0.26 to 0.89, P=0.02). There were no significant differences in incidence of myocardial infarction, all cause mortality, stroke and stent thrombosis between two groups. Compared with 24 months dual antiplatelet therapy group, the incidence of stent thrombosis in the 12 months dual antiplatelet therapy group was higher (OR=2.50, 95%CI 1.13 to 5.61, P=0.02), but the incidence of bleeding in 12 months dual antiplatelet therapy group was lower (OR=0.25, 95%CI 0.07 to 0.89, P=0.03). No significant differences were found in the incidence of myocardial infarction, all cause mortality and stroke between 12 months dual antiplatelet therapy group and 24 months dual antiplatelet therapy group. Conclusions 6 months dual antiplatelet therapy following new-generation drug-eluting stent implantation is relatively more safe and efficacy. There is significant increase of incidence of bleeding in 12 or 24 months dual antiplatelet therapy. Due to the limited quantity and quality of included studies, the above results are needed to be validated by more high quality studies.

  • Endothelial function and prognosis of patients with type 2 diabetes mellitus combined with mid-range ejection fraction heart failure

    ObjectiveTo explore the effect of type 2 diabetes mellitus (T2DM) on the vascular endothelial function of patients with heart failure with mid-range ejection fraction (HFmrEF), and the impact of endothelial function damage on the long-term prognosis of HFmrEF. Metohds87 patients with T2DM and heart failure with mid-range ejection fraction (T2DM-HFmrEF), 98 patients with HFmrEF alone, and 70 healthy control who had been hospitalized at the department of cardiology of the First Affiliated Hospital of Xinjiang Medical University from December 2018 to January 2020 were included. The levels of serum TNF-α, IL-6, vWF, eNOs and E-selectin were determined by enzyme-linked immunosorbent assay. The oxidative stress and vascular endothelial function related indicators of the 3 groups were analyzed. The primary endpoint (all-cause death, exacerbation of heart failure and rehospitalization, or exacerbation of heart failure) and secondary endpoint events (non-fatal myocardial infarction, stable and unstable angina pectoris, or stroke) were followed up for 1 year after discharge.ResultsThe levels of TNF-α, IL-6, vWF, and E-selectin in the HFmrEF combined with diabetes group were higher than those in the HFmrEF without diabetes group (P<0.05). Multivariate Cox regression analysis showed that BNP (HR=1.001, P=0.036), eNOs (HR=1.04, P<0.001), and IL-6 (HR=1.002, P<0.001) were related to the primary end point of all patients with HFmrEF. Glycated hemoglobin (HR=1.37, P=0.046), E-selectin (HR=1.01, P=0.003), vWF (HR=1.02, P=0.017), and IL-6 (HR=1.006, P=0.005) were related to the secondary end point of all patients with HFmrEF. The results of subgroup analyze showed that E-selectin (HR=1.014, P=0.012) and IL-6 (HR=1.008, P=0.007) were related to the secondary endpoint events in the HFmrEF combined with diabetes group, but were not related to the secondary end point events of the non-diabetic group (P>0.05).ConclusionsOxidative stress and vascular endothelial function damage may be involved in the pathogenesis of T2DM-HFmrEF. Serum IL-6 and E-selectin levels are related to the endpoint events in T2DM-HFmrEF patients.

  • Impact of the neutrophil/lymphocyte ratio on the prognosis of short term outcomes in acute aortic dissection patients: a meta-analysis

    Objective To systematically review the relationship between the neutrophil to lymphocyte ratio (NLR) and the short-term prognosis of patients with acute aortic dissection. MethodDatabases including PubMed, Web of Science, CNKI, CBM, and WanFang Data were electronically searched to collect studies on the prognosis associated with neutrophil/lymphocyte ratio and acute aortic dissection from inception to July 2021. Two reviewers independently screened literature, extracted data, and evaluated the risk of bias of the included studies. Meta-analysis was then performed using RevMan 5.4 software. Results A total of 10 case-control studies involving 1 638 patients were included. The results of meta-analysis revealed that the in-hospital mortality group of patients with acute aortic dissection had higher NLR levels than the survival group (MD=4.94, 95%CI 2.67 to 7.61, P<0.0001). In patients with acute aortic dissection, there was no statistical difference in in-hospital mortality between the low NLR group and the high NLR group (OR=3.03, 95%CI 1.00 to 9.15, P=0.05). Conclusion Patients with acute aortic dissection who died in hospital shows higher NLR levels than those who survived. However, due to the quantity and quality of included studies, the above conclusions are needed to be verified by more high-quality studies.
