BNP (B-type natriuretic peptide) and anaemia are both associated with adverse outcome in patients with chronic heart failure. Whether low haemoglobin levels are independently predictive of elevated BNP levels in subjects without heart failure is unknown. In the present study, we examined the relationship between haemoglobin and BNP levels in 234 patients with suspected coronary heart disease without a history of chronic heart failure, adjusting for known predictors of BNP levels. By univariate analysis, haemoglobin levels were inversely related to logarithmically transformed BNP values (r=−0.30, P<0.0001). After adjustment for patient age, gender, body mass index, history of myocardial infarction, use of diuretics, angiotensin-converting enzyme inhibitors and β-blockers, estimated creatinine clearance rate, extent of coronary disease, left ventricular ejection fraction and left ventricular end-diastolic pressure, blood haemoglobin remained an independent predictor of plasma BNP (standardized β-coefficient=−0.253, P<0.0001). A similar relationship was observed between haematocrit and BNP (standardized β-coefficient −0.215, P<0.0001). We conclude that haemoglobin levels are independently predictive of plasma BNP levels in patients with suspected coronary heart disease without heart failure. Anaemia may contribute to elevated BNP levels in the absence of heart failure, and may represent an important confounder of the relationship between BNP, cardiac function and prognosis.

The modern medical literature practically does not contain clinical publications reporting studies of factors responsible for progression of atrial fibrillation (AF) in patients with coronary heart disease (CHD). It accounts for the importance of investigations into evolution of the clinical course of AF in such patients.Aim. To elucidate evolution of the clinical course of AF in patients with CHD in a long-term prospective study.Materials and methods. The study included. 112 patient aged 57-74 (mean 67.44±3.3) years with CHD and paroxysmal form of AF carried outfrom 2011 to 2015. Evolution of the clinical course of AF was evaluated based on the number of arrhythmic attacks during the last 3 months. The appearance ofprolonged persistent AF episodes or permanent AF was regarded as progression of arrhythmia.Results. During the 4 year study, 64 (57,2%) patients (group 1) did not experiencea rise in the frequency and duration of AF attacks. Progression of arrhythmia was documented in 48 (42,8%) of the 112 (100%) patients (group 2). These patients more frequently had the history of myocardial infarction and chronic heart failure than patients of group 1. The latter had the mean values of left ventricular (LV) ejection fraction 61,23±6,24%, i.e. significantly higher than 48,47±8,4% in group 2.47 and 28 % of the patients in group 2and 1 respectively suffered mitral regurgitation (p<0,05). Patients of group 2 had significantly more akineticzones. Intake of nitroglycerin in group 1 resulted in positive dynamics of local LV contractility that did not change in patients of group 2. Conclusion. 42,8% of the patients with CHD and paroxysmal form of AF experienced progression of arrhythmia into a persistent or permanent form. Predictors of AF progression in patients with CHD are the history of myocardial infarction, chronic heart failure, mitral regurgitation, and irreversible changes in local myocardial LV contraction.

Abstract Background. Oxidative stress (OS) and inflammation are major mechanisms involved in the progression of chronic heart failure (CHF). Serum uric acid (sUA) is related to CHF severity and could represent a marker of xanthine-oxidase activation. The relationship between sUA, oxidative stress (OS) and inflammation markers was assessed in patients with moderate-severe CHF and reduced left ventricular (LV) ejection fraction (EF). Methods. In 57 patients with stable CHF, functional NYHA class III, with EF<40%, the LV function was assessed by N-terminal of the prohormone brain natriuretic peptide (NT-proBNP) levels and echocardiographically through the EF and E/e’ ratio, a marker of LV filling pressures. The relationship between LV function, sUA, malondialdehyde (MDA), myeloperoxidase (MPO), paraoxonase 1 (PON-1) as OS markers and high sensitivity C-reactive protein (hsCRP) and interleukin 6 (IL-6) as markers of systemic inflammation was evaluated. Results. The mean sUA level was 7.9 ± 2.2 mg/dl, and 61% of the CHF patients had hyperuricemia. CHF patients with elevated LV filling pressures (E/e’ ≥ 13) had higher sUA (8.6 ± 2.3 vs. 7.3 ± 1.4, p=0.08) and NT-proBNP levels (643±430 vs. 2531±709, p=0.003) and lower EF (29.8 ± 3.9 % vs. 36.3 ± 4.4 %, p=0.001). There was a significant correlation between sUA and IL-6 (r = 0.56, p<0.001), MDA (r= 0.49, p= 0.001), MPO (r=0.34, p=0.001) and PON-1 levels (r= −0.39, p= 0.003). Conclusion. In CHF, hyperuricemia is associated with disease severity. High sUA levels in CHF with normal renal function may reflect increased xanthine-oxidase activity linked with chronic inflammatory response.

The purpose of this study was to evaluate whether CC-AAbs levels could predict prognosis in CHF patients. A total of 2096 patients with CHF (841 DCM patients and 1255 ICM patients) and 834 control subjects were recruited. CC-AAbs were detected and the relationship between CC-AAbs and patient prognosis was analyzed. During a median follow-up time of 52 months, there were 578 deaths. Of these, sudden cardiac death (SCD) occurred in 102 cases of DCM and 121 cases of ICM. The presence of CC-AAbs in patients was significantly higher than that of controls (bothP<0.001). Multivariate analysis revealed that positive CC-AAbs could predict SCD (HR 3.191, 95% CI 1.598–6.369 for DCM; HR 2.805, 95% CI 1.488–5.288 for ICM) and all-cause mortality (HR 1.733, 95% CI 1.042–2.883 for DCM; HR 2.219, 95% CI 1.461–3.371 for ICM) in CHF patients. A significant association between CC-AAbs and non-SCD (NSCD) was found in ICM patients (HR = 1.887, 95% CI 1.081–3.293). Our results demonstrated that the presence of CC-AAbs was higher in CHF patients versus controls and corresponds to a higher incidence of all-cause death and SCD. Positive CC-AAbs may serve as an independent predictor for SCD and all-cause death in these patients.

Background: Although natriuretic peptides are increasingly used for the management of chronic heart failure (CHF), there are sparse comparative data. Therefore, we compared the importance of influencing factors, the ability to detect left ventricular systolic dysfunction, and the prognostic power of midregional pro-atrial natriuretic peptide (MR-proANP), B-type natriuretic peptide (BNP), and aminoterminal pro-B-type natriuretic peptide (NT-proBNP) in patients with chronic heart failure. Methods and Results: MR-proANP, using a new assay directed at the midregion of aminoterminal-proANP, was compared with BNP and NT-proBNP, using conventional assays, in 797 patients with CHF. All three natriuretic peptides were independently influenced by left ventricular ejection fraction (LVEF), glomerular filtration rate (GFR), and the presence of ankle edema. Area under receiver-operator characteristic curves for detection of an LVEF <40% were similar between MR-proANP (0.799 [0.753– 0.844]) and BNP (0.803 [0.757– 0.849]), and NT-proBNP (0.730 [0.681– 0.778]. During a median observation time of 68 months, 492 patients died. In multiple Cox regression analysis each natriuretic peptide was the strongest prognostic parameter among various clinical variables, but proportion of explained variation showed that NT-proANP was a significantly stronger predictor of death than NT-proBNP and BNP (Figure ). Conclusions: Despite similarities in influencing factors and detection of reduced LVEF, MR-proANP outperformed BNP and NT-proBNP in the prediction of death. A new assay technology and the high biological stability of MR-proANP are potential explanations for these findings.

It has been well documented that there is an increased prevalence of standard cardiovascular (CV) risk factors in association with diabetes and with diabetes-related abnormalities. Hyperglycemia, in particular, also plays an important role. Heart failure (HF) has become a frequent manifestation of cardiovascular disease (CVD) among individuals with diabetes mellitus. Epidemiological studies suggest that the effect of hyperglycemia on HF risk is independent of other known risk factors. Analysis of datasets from populations including individuals with dysglycemia suggests the pathogenic role of hyperglycemia on left ventricular function and on the natural history of HF. Despite substantial epidemiological evidence of the relationship between diabetes and HF, data from available interventional trials assessing the effect of a glucose-lowering strategy on CV outcomes are limited. To provide some insight into these issues, we describe in this review the recent important data to understand the natural course of CV disease in diabetic individuals and the role of hyperglycemia at different times in the progression of HF.

Objective: To compare the efficacy and safety of conventional treatments (CTs) to those that included traditional Chinese medicine injections (TCMIs) in patients with combined coronary heart disease and heart failure (CHD-HF).Methods: Eight electronic literature databases (PubMed, Embase, Cochrane Central Register of Controlled Trials, Web of Science, China National Knowledge Infrastructure Database, Chinese Scientific Journal Database, Wanfang Database, Chinese Biomedical Database) were searched from their inceptions to May 18, 2021, to identify relevant randomised controlled trials (RCTs). The primary outcomes analyzed included the total effectiveness rate and adverse events (ADRs). The secondary outcomes analyzed included the left ventricular ejection fraction (LVEF), N-terminal pro-brain natriuretic peptide (NT-proBNP), brain natriuretic peptide (BNP), and 6-min walk test (6MWT). Cochrane risk-of-bias tool was used to assess quality of the analyzed RCTs. Stata and OpenBUGS software were used to prior to the systematic review and network meta-analysis.Results: Sixty-one eligible trials involved 5,567 patients and one of the following 15 TCMIs: Shuxuetong, Shenmai, Shenfu, Shengmai, Danshenduofenyansuan, Danhong, Dazhuhongjingtian, Xinmailong, Dengzhanxixin, Gualoupi, Shuxuening, Xuesaitong, Yiqi Fumai, Shenqi Fuzheng, Huangqi. Network meta-analysis revealed that Shuxuetong injection + CT group was superior to CT only in improving the total effectiveness rate [odds ratio (OR): 7.8, 95% confidence interval (CI): 1.17–27.41]. Shenmai injection + CT was superior to CT only for LVEF (OR: 8.97, CI: 4.67–13.18), Xinmailong injection + CT was superior to CT only for NT-proBNP (OR: −317.70, CI: −331.10–303.10), Shenqi Fuzheng injection + CT was superior to CT only for BNP (OR: −257.30, CI: −308.40–242.80); and Danhong injection + CT was superior to CT only for 6MWT (OR: 84.40, CI: 62.62−106.20). Different TCMIs had different toxicity spectrums.Conclusion: TCMIs combined with CT are better than CT alone in treating CHD-HF. Different TCMIs improve different outcomes. Additional properly designed RCTs are needed to conduce a more refined comparison of various TCMIs.Systematic Review Registration: [https://www.crd.york.ac.uk/PROSPERO/], identifier [CRD42021258263].
