ABSTRACT
Background and Objectives@#Venous thromboembolism (VTE), consisting of deep vein thrombosis (DVT) and pulmonary embolism (PE), is highly prevalent in in-hospital HF patients and contributes to worse prognoses. However, the risk of VTE in out-patients with HF in long-term period is controversial. This study aimed to evaluate the associations between HF and the risk of VTE in a long-term follow-up duration. @*Methods@#We searched for studies investigating the risk of VTE, PE, and DVT in patients with HF before April 15, 2020, in PubMed, MEDLINE, and Embase databases. Cohort studies and post hoc analysis of RCTs were eligible for inclusion if they reported relative risk of VTE, DVT or PE in patients with HF in more than 3-month follow-up period. @*Results@#We identified 31 studies that enrolled over 530,641 HF patients. Overall, patients with HF were associated with an increased risk of VTE (risk ratio [RR]=1.57, 95% confidence interval [CI]=1.34–1.84) and PE (RR=2.00, 95% CI=1.38–2.89). However, the risk of DVT was not significantly increased in HF patients (RR=1.33, 95% CI=0.67–2.63). Subgroup analysis showed that patients with chronic HF (RR=1.54, 95% CI=1.32–1.80) had a higher risk of VTE than those with acute HF (RR=0.95, 95% CI=0.68–1.32). @*Conclusions@#In conclusion, HF was an independent risk for VTE and PE but not DVT in a longterm follow-up period. Patients with chronic HF were prone to suffer from VTE than acute HF.

ABSTRACT
Objective To compare the clinical characteristics,and outcomes of patients with heart failure with different left ventricular ejection fractions (LVEF).Methods A total of 1 182 hospitalized patients with heart failure (HF) were enrolled and retrospectively studied in the present study.The patients were stratified by LVEF as reduced (HFrEF,LVEF ＜ 40％,n =313),mid-range (HFmrEF,40％ ≤ LVEF ＜50％,n =287) and preserved (HFpEF,LVEF≥50％,n =582) ejection fraction groups.Among the 1 182 cases,941 of them (81.3％,84.9％,and 84.0％ inHFrEF,HFmrEF and HFpEF groups,respectively) were followed up for an median duration of 27.3 months.Results (1) Among the study patients,26.5％ were in HFrEF,24.3％ in HFmrEF,and 49.2％ in HFpEF groups.(2) Ischemic heart disease with HFmrEF was more frequent than that in patients with HFrEF.The average age,percentage of female subjects,systolic blood pressure,uric acid,N terminal B-type natriuretic peptide precursor (NT-proBNP),hemoglobin,and the incidence of hypertensive heart disease,anemia,atrial fibrillation in patients with HFmrEF were higher than those in patients with HFrEF,but lower than those in patients with HFpEF (all P ＜0.01).(3) The all-cause cumulative mortality was 10.8％ at 1 year,20.6％ at 2 years and 35.9％ at 5 years.No difference was observed in the all-cause cumulative mortality at 1 year,2 years,5 years among the three groups (all P ＞ 0.05).Conclusions The HFmrEF patients,as a new and distinct group,were with many intermediate characteristics compared with HFrEF and HFpEF subjects.However,the all-cause mortality was not significantly differeut among HF patients with different LVEF.
ABSTRACT
Objective: To explore the relationship between serum levels of immunoglobulin E (IgE) and calciifc aortic valve disease (CAVD) in relevant patients. Methods: A total of 394 patients were enrolled in our study. Based on echocardiography presentation, the patients were divided into 2 groups: CAVD group,n=169 and Non-CAVD group,n=225. Serum levels of IgE were examined by chemiluminescence method. The IgE levels were compared between 2 groups and the relationship between serum IgE level and CAVD was analyzed. Results: Serum levels of IgE in CAVD group was significantly higher than Non-CAVD group 113.30 IU/ml vs 63.76 IU/ml (P Conclusion: Serum IgE level is obviously increased in CAVD patients. IgE is an independent biochemical indicator of CAVD, it may play the important role in CAVD pathogenesis.
