Early Management of Blood Lipid Levels with Non-Statin Lipid-Lowering Drugs in Acute Coronary Syndrome: A Mini Review.

Acute coronary syndrome (ACS) remains a major cause of morbidity and mortality, despite many improvements in its prevention and management. Lipid management is an important aspect of secondary prevention after ACS. Previous studies indicate that the early use of intensive statin therapy in patients with ACS may alleviate the risk of recurrent cardiovascular events and mortality. However, many patients do not reach the target low-density lipoprotein cholesterol (LDL-C) level of < 55 mg/dL with statin monotherapy, and muscle-related adverse effects caused by statins hinder adherence to treatment. Novel non-statin agents are recommended for patients who cannot achieve the target LDL-C levels with high-intensity statin therapy and those with statin intolerance. The combination of statins and non-statins may synergistically affect intensively lowering LDL-C through different mechanisms, which could lead to better cardiovascular outcomes than statin monotherapy. However, it remains uncertain whether the early use of combination lipid-lowering therapy is more beneficial. The present review summarizes the benefits of intensive statin monotherapy and their early combination with non-statin medications including ezetimibe, PCSK9 inhibitors, inclisiran, and bempedoic acid (BDA) in the management of ACS.

The use of non-vitamin K antagonist oral anticoagulants in chronic thromboembolic pulmonary hypertension: an updated meta-analysis.

Studies have demonstrated the beneficial effects of non-vitamin K antagonist oral anticoagulants (NOACs) for the treatment of atrial fibrillation and venous thromboembolism (VTE). The impact of NOACs on chronic thromboembolic pulmonary hypertension (CTEPH) remains controversial. This meta-analysis was conducted to investigate the effectiveness and safety of NOACs compared with vitamin K antagonists (VKAs) in patients with CTEPH. A comprehensive search of PubMed, Embase, and Cochrane Library was conducted for relevant studies, encompassing data from inception until November 2023. The data were pooled using a fixed-effects model if the I2 value was less than 50%; otherwise, a random-effects model was employed. Overall, two randomized controlled trials (RCTs) and eight observational studies involving 4556 patients with CTEPH were included. Patients receiving NOACs exhibited a significantly lower incidence of all-cause mortality (odds ratio [OR] = 0.52, 95% confidence interval [CI]: 0.36-0.76) and major bleeding (OR = 0.58, 95% CI: 0.36-0.92) compared to those with VKAs. There were no significant differences in the rate of VTE recurrence (OR = 1.07, 95% CI: 0.72-1.59), total bleeding (OR = 0.78, 95% CI: 0.60-1.01), and minor bleeding (OR = 1.11, 95% CI: 0.73-1.69) between the two studied groups. Similar results were found in the subgroup analysis and sensitivity analysis.This meta-analysis provided evidence that NOACs could be superior to VKAs for the treatment of CTEPH. NOACs might be safe and a convenient alternative to VKAs for thromboprophylaxis in patients with CTEPH.

Hemoglobin to red cell distribution width ratio: A predictor of clinical outcome and diuretic response in patients with acute heart failure.

BACKGROUND: Hemoglobin to Red Cell Distribution Width Ratio (HRR) is a novel inflammatory marker in the prognostic assessment of tumors. Nevertheless, its focus on the cardiovascular field is relatively limited, particularly regarding its correlation with diuretic responses and clinical outcomes. METHODS: This is a secondary analysis of the Renal Optimization Strategies Evaluation (ROSE AHF) clinical trial. The outcomes of interest included all-cause death, rehospitalization and diuretic responses. Multivariable Cox proportional hazard regression and linear regression models were performed, respectively. Prognostic outcomes and diuretic response were further evaluated in ejection fraction (EF) subgroups (preserved EF ≥ 50% and reduced EF<50%). RESULTS: A total of 351 patients were included in the present study and further categorized according to HRR median (0.7131) value at admission: low HRR group (n = 176) and high HRR group (n = 175). High HRR were found to be independently associated with decreased risk of all-cause death (HR = 0.51; 95% CI,0.30-0.87, P = 0.013), reduced risk of developing all-caused death or rehospitalization (HR = 0.62; 95% CI,0.39-0.98, P = 0.039). Furthermore, high HRR indicated lower cumulative urine output (OR: -992.33, P = 0.004) and less weight loss (OR: 3.08, P < 0.001) within 72 h after diuresis. Subgroup analysis revealed no significant interaction effect between EF and HRR in prognostic impact or diuretic responses, and HRR was negatively correlated with plasma volume. CONCLUSION: High HRR demonstrated a lower risk of developing adverse clinical outcomes and a poorer diuretic response that might be due to less volume overload in AHF patients.

Clinical Implication of N-Terminal Pro-Brain Natriuretic Peptide Burden in Heart Failure With Reduced Ejection Fraction: From the GUIDE-IT.

This study aimed to explore the prognostic implication of N-terminal pro-brain natriuretic peptide (NT-proBNP) burden on heart failure (HF) with reduced ejection fraction (HFrEF). We performed a post hoc analysis of the GUIDing Evidence Based Therapy Using Biomarker Intensified Treatment in Heart Failure (GUIDE-IT) trial. NT-proBNP burden was defined as the proportion of days with increased NT-proBNP (≥1,800 pg/ml) to the whole observation time. A Cox proportional hazards regression model was used to evaluate the association with NT-proBNP burden and prognosis. A total of 815 patients with HFrEF were analyzed in our study. Patients were categorized into 4 groups according to the degree of NT-proBNP burden. In the multivariate Cox analysis, NT-proBNP burden was significantly associated with all-cause mortality, cardiovascular mortality, and HF hospitalization. Compared with patients without NT-proBNP burden, the risk for the composite outcome increased by 210% (hazard ratio [HR] 3.10, 95% confidence interval [CI] 1.72 to 5.58, p <0.001) in NT-proBNP burden 1 (mild) group, 432% (HR 5.32, 95% CI 2.93 to 9.67, p <0.001) in NT-proBNP burden 2 (moderate) group, and over 12 times (HR 13.15, 95% CI 7.42 to 23.33, p <0.001) in NT-proBNP burden 3 (severe) group. The sensitivity analyses stratified by age and renal function yielded similar results. A higher NT-proBNP burden was associated with a significant increase in risks of all-cause mortality, cardiovascular mortality, HF hospitalization, and composite outcome. The results suggested that NT-proBNP burden could be an important predictor of the prognosis of patients with HFrEF.

S2I2N0-3 score predicts short- and long-term mortality and morbidity in HFrEF: a post-hoc analysis of the GUIDE-IT trial.

AIMS: This study investigated the S2I2N0-3 score, a simple tool comprising stroke history, insulin-treated diabetes, and N-terminal pro-brain natriuretic peptide, for forecasting mortality and morbidity in heart failure (HF) with reduced ejection fraction (HFrEF). METHODS AND RESULTS: Analysing 890 GUIDE-IT HFrEF trial participants, we stratified them by baseline S2I2N0-3 risk score into three risk groups. We examined the score's association with five adverse outcomes over short (90 days) and extended periods (median follow-up of 15 months) using Cox and competing risk models. Our analysis revealed significant positive associations between the S2I2N0-3 strata and adverse outcomes. When analysed as a continuous variable, each point increment of the S2I2N0-3 score was associated with a higher risk of short- and long-term cardiovascular death [short term: hazard ratio (HR) 1.43, 95% confidence interval (CI) 1.03-1.98; long term: HR 1.18, 95% CI 1.02-1.38], all-cause death (HR 1.52, 95% CI 1.12-2.07; HR 1.18, 95% CI 1.03-1.36), HF hospitalization (HR 1.39, 95% CI 1.20-1.62; HR 1.18, 95% CI 1.06-1.31), any hospitalization (HR 1.19, 95% CI 1.06-1.34; HR 1.09, 95% CI 1.00-1.19), and the composite outcome of cardiovascular death and HF hospitalization (HR 1.39, 95% CI 1.21-1.60; HR 1.17, 95% CI 1.06-1.30). The S2I2N0-3 demonstrated reliable prognostic value, with C-indices ranging from 0.619 to 0.753 across outcomes and time points. When compared with the Meta-Analysis Global Group in Chronic Heart Failure (MAGGIC) score using Z-statistics, net reclassification index, and integrated discrimination improvement, the S2I2N0-3 showed comparable predictive power for all outcomes during both short- and long-term follow-ups. CONCLUSIONS: The S2I2N0-3 risk score had modest predictive values for both short- and long-term clinical outcomes in HFrEF patients, offering equivalent performance to the established MAGGIC score.

Estimated pulse wave velocity predicts mortality in patients with heart failure with preserved ejection fraction.

OBJECTIVE: Estimated pulse wave velocity (ePWV), a newly established arterial stiffness (AS) parameter, predicts the development of cardiovascular disease (CVD) and death in the general population or in patients with CVD risk factors. However, whether ePWV is associated with adverse outcomes in heart failure with preserved ejection fraction (HFpEF) patients remains unknown. Our study aimed to evaluate the prognostic value of ePWV on clinical outcomes in HFpEF. METHODS AND RESULTS: We analyzed HFpEF participants from the Americas in the Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist (TOPCAT) trial with available baseline data (n = 1764). Cox proportional hazard model was used to explore the prognostic value of ePWV on long-term clinical outcomes (all-cause mortality, cardiovascular mortality, all-cause hospitalization, and heart failure hospitalization). Each ePWV increase by 1 m/s increased the risk for all-cause death by 16% (HR:1.16; 95% CI:1.10-1.23; P < 0.001) and CVD mortality by 13% (HR:1.13; 95% CI:1.04-1.21; P = 0.002) after adjusting for confounders. Patients were then grouped into 4 quartiles of ePWV. Our study indicated that the highest ePWV quartile (ePWV ≥ 12.806 m/s) was associated with increased risk of all-cause mortality (HR: 1.96; 95% CI: 1.43-2.69; P < 0.001) and CVD mortality (HR: 1.72; 95% CI: 1.16-2.56; P = 0.008) after adjusting for potential confounders. CONCLUSION: These results suggested ePWV is independently associated with increased all-cause mortality and CVD mortality in HFpEF patients, indicating ePWV is an appropriate predictor of prognosis in patients with HFpEF.

The long noncoding RNA CARDINAL attenuates cardiac hypertrophy by modulating protein translation.

One of the features of pathological cardiac hypertrophy is enhanced translation and protein synthesis. Translational inhibition has been shown to be an effective means of treating cardiac hypertrophy, although system-wide side effects are common. Regulators of translation, such as cardiac-specific long noncoding RNAs (lncRNAs), could provide new, more targeted therapeutic approaches to inhibit cardiac hypertrophy. Therefore, we generated mice lacking a previously identified lncRNA named CARDINAL to examine its cardiac function. We demonstrate that CARDINAL is a cardiac-specific, ribosome-associated lncRNA and show that its expression was induced in the heart upon pathological cardiac hypertrophy and that its deletion in mice exacerbated stress-induced cardiac hypertrophy and augmented protein translation. In contrast, overexpression of CARDINAL attenuated cardiac hypertrophy in vivo and in vitro and suppressed hypertrophy-induced protein translation. Mechanistically, CARDINAL interacted with developmentally regulated GTP-binding protein 1 (DRG1) and blocked its interaction with DRG family regulatory protein 1 (DFRP1); as a result, DRG1 was downregulated, thereby modulating the rate of protein translation in the heart in response to stress. This study provides evidence for the therapeutic potential of targeting cardiac-specific lncRNAs to suppress disease-induced translational changes and to treat cardiac hypertrophy and heart failure.

Mortality in patients admitted to hospital with heart failure in China: a nationwide Cardiovascular Association Database-Heart Failure Centre Registry cohort study.

BACKGROUND: China has the largest burden of heart failure worldwide. However, large-scale studies on heart failure mortality are scarce. We aimed to investigate mortality and identify risk factors for mortality among patients with heart failure in China. METHODS: This prospective cohort study used data from the China Cardiovascular Association (CCA) Database-Heart Failure Centre Registry, which were linked to the National Mortality Registration Information Management System by the Chinese Centre for Disease Control and Prevention. We included patients enrolled from Jan 1, 2017, to Dec 31, 2021, across 572 CCA Database-Heart Failure Centre certified hospitals in 31 provinces of mainland China. Eligible patients were aged 18 years or older (younger than 100 years) with a principal discharge diagnosis of heart failure based on Chinese heart failure guidelines. All-cause mortality at 30 days, 1 year, and 3 years for patients with heart failure were calculated and the causes of death were recorded. Multivariable analysis was used to analyse factors associated with all-cause mortality and cardiovascular mortality. This study was registered with the Chinese Clinical Trial Registry, ChiCTR2200066305. FINDINGS: Of the 327 477 patients in the registry, 230 637 eligible adults with heart failure were included in our analyses. Participant mean age was 69·3 years (SD 13·2), 94 693 (41·1%) participants were female, and 135 944 (58·9%) were male. The median follow-up time was 531 days (IQR 251-883). Post-discharge all-cause mortality of patients with heart failure at 30 days was 2·4% (95% CI 2·3-2·5), at 1 year was 13·7% (13·5-13·9), and at 3 years was 28·2% (27·7-28·6). Cardiovascular death accounted for 32 906 (71·5%) of 46 006 all-cause deaths. Patients with heart failure with reduced ejection fraction had the highest all-cause mortality. A lower guideline adherence score was independently associated with the increase of all-cause and cardiovascular mortality. INTERPRETATION: In China, mortality for patients with heart failure is still high, especially in patients with reduced ejection fraction. Our findings suggest that guideline-directed medical therapy needs to be improved.

Edoxaban for stroke prevention in atrial fibrillation and factors associated with dosing: patient characteristics from the prospective observational ETNA-AF-China registry.

Real-world data on effectiveness and safety of a single non-vitamin K antagonist oral anticoagulant in the Chinese population with atrial fibrillation (AF) are limited. This study reports characteristics of patients treated with edoxaban and factors associated with dosing patterns from routine care in China. ETNA-AF-China (NCT04747496) is a multicentre, prospective, observational study enrolling edoxaban-treated patients from four economic regions with a targeted 2-year follow-up. Of the 4930 patients with AF (mean age: 70.2 ± 9.5 years; male, 57.1%), the mean creatinine clearance (CrCl), CHA2DS2-VASc, and HAS-BLED scores were 71.2 mL/min, 2.9, and 1.6. Overall, 6.4% of patients were perceived as frail by investigators. Available label dose reduction criteria (N = 4232) revealed that 3278 (77.5%) patients received recommended doses and 954 (22.5%) non-recommended doses. Northeast (53.0%) and West (43.1%) regions had the highest prescriptions of 60 mg and 30 mg recommended doses, respectively. Non-recommended 30 mg doses were more frequently prescribed in patients with antiplatelet use and history of heart failure than recommended 60 mg. Multivariate analysis identified advanced age as the strongest associated factor with non-recommended doses. Frailty had the strongest association with 30 mg except for age, and history of TIA was the most relevant factor associated with 60 mg. In conclusion, patients in the ETNA-AF-China study were predominantly aged 65 years and older, had mild-to-moderate renal impairment and good label adherence. Advanced age was associated with non-recommended doses, with frailty most common for non-recommended 30 mg and a history of TIA for the non-recommended 60 mg dose.

Effectiveness and safety of ivabradine in Chinese patients with chronic heart failure: an observational study.

AIMS: A therapeutic strategy for chronic heart failure (HF) is to lower resting heart rate (HR). Ivabradine is a well-known HR-lowering agent, but limited prospective data exist regarding its use in Chinese patients. This study aimed to evaluate the effectiveness and safety of ivabradine in Chinese patients with chronic HF. METHODS AND RESULTS: This multicentre, single-arm, prospective, observational study enrolled Chinese patients with chronic HF. The primary outcome was change from baseline in HR at 1 and 6 months, measured by pulse counting. Effectiveness was also evaluated using laboratory tests, the Kansas City Cardiomyopathy Questionnaire (KCCQ) clinical summary score (CSS) and overall summary score (OSS), and New York Heart Association (NYHA) class. Treatment-emergent adverse events (TEAEs) were assessed. A post hoc analysis examined the effectiveness and safety of ivabradine combined with an angiotensin receptor-neprilysin inhibitor (ARNI) or beta-blocker. A total of 1003 patients were enrolled [mean age 54.4 ± 15.0 years, 773 male (77.1%), mean baseline HR 88.5 ± 11.3 b.p.m., mean blood pressure 115.7/74.4 ± 17.2/12.3 mmHg, mean left ventricular ejection fraction 30.9 ± 7.6%, NYHA Classes III and IV in 48.8% and 22.0% of patients, respectively]. HR decreased by a mean of 12.9 and 16.1 b.p.m. after 1 and 6 months, respectively (both P < 0.001). At Month 6, improvements in the KCCQ CSS and OSS of ≥5 points were observed in 72.1% and 74.1% of patients, respectively (both P < 0.001). Left ventricular ejection fraction increased by 12.1 ± 11.6 (P < 0.001), and 66.7% of patients showed improvement in NYHA class (P < 0.001). At Month 6, the overall proportion of patients in NYHA Classes III and IV was reduced to 13.5% and 2.1%, respectively. Serum brain natriuretic peptide (BNP) and N-terminal pro-BNP changed by -331.9 ng/L (-1238.6, -134.0) and -1113.8 ng/L (-2202.0, -297.2), respectively (P < 0.001). HR reductions and improvements in NYHA and KCCQ scores with ivabradine were similar with and without use of ARNIs or beta-blockers. Of 498 TEAEs in 296 patients (29.5%), 73 TEAEs in 55 patients (5.5%) were considered related to ivabradine [most frequent sinus bradycardia (n = 7) and photopsia (n = 7)]. TEAEs were reported in a similar number of patients in ARNI and beta-blocker subgroups (21.9-35.6%). CONCLUSIONS: Ivabradine treatment reduced HR and improved cardiac function and health-related quality of life in Chinese patients with chronic HF. Benefits were seen irrespective of whether or not patients were also taking ARNIs or beta-blockers. Treatment was well tolerated with a similar profile to previous ivabradine studies.

The traditional Chinese medicine Qiliqiangxin in heart failure with reduced ejection fraction: a randomized, double-blind, placebo-controlled trial.

Previous findings have indicated the potential benefits of the Chinese traditional medicine Qiliqiangxin (QLQX) in heart failure. Here we performed a double-blind, randomized controlled trial to evaluate the efficacy and safety of QLQX in patients with heart failure and reduced ejection fraction (HFrEF). This multicenter trial, conducted in 133 hospitals in China, enrolled 3,110 patients with HFrEF with NT-proBNP levels of ≥450 pg ml-1 and left ventricular ejection fraction of ≤40%. Participants were randomized to receive either QLQX capsules or placebo (four capsules three times daily) alongside standard heart failure therapy. The trial met its primary outcome, which was a composite of hospitalization for heart failure and cardiovascular death: over a median follow-up of 18.3 months, the primary outcome occurred in 389 patients (25.02%) in the QLQX group and 467 patients (30.03%) in the placebo group (hazard ratio (HR), 0.78; 95% confidence interval (CI), 0.68-0.90; P < 0.001). In an analysis of secondary outcomes, the QLQX group showed reductions in both hospitalization for heart failure (15.63% versus 19.16%; HR, 0.76; 95% CI, 0.64-0.90; P = 0.002) and cardiovascular death (13.31% versus 15.95%; HR, 0.83; 95% CI, 0.68-0.996; P = 0.045) compared to the placebo group. All-cause mortality did not differ significantly between the two groups (HR, 0.84; 95% CI, 0.70-1.01; P = 0.058) and adverse events were also comparable between the groups. The results of this trial indicate that QLQX may improve clinical outcomes in patients with HFrEF when added to conventional therapy. ChiCTR registration: ChiCTR1900021929 .
