Journal requirement for data sharing statements in clinical trials: a cross-sectional study.

OBJECTIVE: Data sharing statements are considered routine in clinical trial reporting, and represent a step towards data transparency. The International Committee of Medical Journal Editors (ICMJE) require clinical trials to publish data sharing statements. To assess requirement for data sharing statements by biomedical journals, and to explore associations between journal characteristics and requirement for data sharing statements. STUDY DESIGN AND SETTING: In this cross-sectional study, we included all biomedical journals that published clinical trials from January 1st, 2019 to December 31st, 2022 and that were indexed by the Journal Citation Reports. The study outcome was the journal requirement for data sharing statements. Multivariable logistic regression analyses were used to assess the relationship between journal characteristics and requirement for data sharing statements. RESULTS: Of the 3,229 biomedical journals included in the analyses, 2,345 (72.6%) required authors to include data sharing statements. Journals published in the UK (OR, 3.19 [95% CI, 2.43 to 4.22]) and endorsing the Consolidated Standards of Reporting Trials (CONSORT) (OR, 3.30 [95% CI, 2.78 to 3.92]) had greater odds of requiring data sharing statements. Journals that were Open Access, non-English language, in the Journal Citation Reports group of clinical medicine, and on the ICMJE list had lower odds of requiring data sharing statements, with ORs ranging from 0.18 to 0.81. CONCLUSION: Despite ICMJE recommendations, more than 27% of biomedical journals do not require clinical trials to include data sharing statements, highlighting room for improved transparency.

Early Rhythm Control and Incident Dementia in Patients With Atrial Fibrillation and Prior Stroke.

BACKGROUND: Although early rhythm control (ERC) in patients with atrial fibrillation (AF) reduces the risk of stroke, there is no evidence thus far on whether ERC reduces the risk of developing dementia in patients with AF and prior stroke. OBJECTIVES: This study sought to evaluate whether ERC reduces the risk of developing dementia in patients with new-onset AF and prior stroke. METHODS: Using the Korean nationwide claims database, we identified patients with new-onset AF and prior stroke between 2010 and 2016. Patients who received rhythm control therapy within 1 year after AF onset were defined as the ERC group, otherwise patients were categorized as the usual care group. A propensity score weighting method was used to balance the 2 groups. Incident dementia defined by relevant diagnostic codes was evaluated. RESULTS: A total of 41,370 patients were included (mean age 70 ± 11 years; mean CHA2DS2-VASc score 5.3±1.6): 10,213 in the ERC group and 31,157 in the usual care group. Compared with usual care, ERC was associated with lower risks of all dementia, Alzheimer's dementia, and vascular dementia (weighted HRs [95% CIs], 0.825 [0.776-0.876], 0.831 [0.774-0.893], and 0.800 [0.702-0.913], respectively, all P < 0.001). The benefit of ERC was slightly accentuated in the younger age group (<65 years). The beneficial effect of ERC in reducing the risk of dementia was consistent regardless of the characteristics of prior stroke. CONCLUSIONS: ERC might be beneficial in the prevention of dementia in patients with AF and prior stroke. To prevent the progression of cognitive dysfunction, ERC should be considered in this population.

Impaired endogenous fibrinolysis status: a potential prognostic predictor in ischemic stroke.

Stroke confers a severe global healthcare burden, hence exploring risk factors for stroke occurrence and prognosis is important for stroke prevention and post-stroke management strategies. Endogenous fibrinolysis is a spontaneous physiological protective mechanism that dissolves thrombus to maintain vascular patency. Recently, impaired endogenous fibrinolysis has been considered as a potential novel cardiovascular risk factor, but its link with ischaemic stroke in the past has been underappreciated. In this review, we summarize the latest mechanisms of endogenous fibrinolysis, review the current evidence and data on endogenous fibrinolysis in ischemic stroke. It includes the structure of thrombus in ischemic stroke patients, the effect of fibrin structure on the endogenous fibrinolytic efficiency, and the association between intravenous thrombolytic therapy and endogenous fibrinolysis in ischemic stroke. It also includes the single factors (tissue plasminogen activator, urokinase plasminogen activator, plasminogen activator inhibitor-1, thrombin activatable fibrinolysis inhibitor, complement component 3, complement component 5, alpha-2-antiplasmin, plasmin-alpha-2-antiplasmin complex, and lipoprotein[a]), and the global assessments of endogenous fibrinolysis status (thromboelastography, rotational thromboelastometry, and global thrombosis test), and their potential as predictors to identify occurrence or unfavorable functional outcomes of ischemic stroke. All of these assessments present advantages and limitations, and we suggest that the global thrombosis test may be more appropriate for detecting impaired endogenous fibrinolysis status in ischemic stroke patients.

Educational status and the risk of adverse outcomes in Asian patients with atrial fibrillation: a report from the prospective APHRS-AF Registry.

BACKGROUND: The aim of this study was to evaluate the impact of educational status (ES) on the clinical course of Asian patients with atrial fibrillation (AF). METHODS: We used data from the prospective APHRS-AF Registry. ES was classified as follows: low (primary school), medium (secondary), and high (University). The primary outcome was a composite of all-cause death, thromboembolic events, acute coronary syndrome, and heart failure. Secondary outcomes were each component of the primary outcome, cardiovascular death, and major bleeding. The one-year risk of primary and secondary outcomes was assessed through Cox-regressions. Adherence to the Atrial fibrillation Better Care (ABC) pathway was assessed. RESULTS: Among 2697 AF patients (69±12 years, 34.8% females), 34.6% had low ES; 37.3% had medium ES; and 28.1% had high ES. Compared to patients with medium-high ES, patients with low ES were older, more often females, with a higher prevalence of cardiovascular risk factors, and a lower ABC pathway adherence (30.4% vs. 40.2%, P<0.001). On multivariable analysis, low ES was associated with a higher risk for the primary outcome (HR 1.52,95%CI 1.11-2.06) and all-cause death (HR 1.76,95%CI 1.10-2.83) than medium-high ES. A significant interaction was found for the risk of composite outcome among the different age strata, with the higher risk in the elderly (P for int=0.008), whereas the beneficial effect of the ABC pathway was irrespective of ES (P for int=0.691). CONCLUSIONS: In Asian AF patients, low ES is associated with high mortality. Efforts to improve education and include ES evaluation in the integrated care approach for AF are necessary to reduce the cardiovascular burden in these patients.

Diagnostic accuracy of digital technologies compared with 12-lead ECG in the diagnosis of atrial fibrillation in adults: A protocol for a systematic review.

BACKGROUND: Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia in the world. AF increases the risk of stroke 5-fold, though the risk can be reduced with appropriate treatment. Therefore, early diagnosis is imperative but remains a global challenge. In low-and middle-income countries (LMICs), a lack of diagnostic equipment and under-resourced healthcare systems generate further barriers. The rapid development of digital technologies that are capable of diagnosing AF remotely and cost-effectively could prove beneficial for LMICs. However, evidence is lacking on what digital technologies exist and how they compare in regards to diagnostic accuracy. We aim to systematically review the diagnostic accuracy of all digital technologies capable of AF diagnosis. METHODS: MEDLINE, Embase and Web of Science will be searched for eligible studies. Free text terms will be combined with corresponding index terms where available and searches will not be limited by language nor time of publication. Cohort or cross-sectional studies comprising adult (≥18 years) participants will be included. Only studies that use a 12-lead ECG as the reference test (comparator) and report outcomes of sensitivity, specificity, the diagnostic odds ratio (DOR) or the positive and negative predictive value (PPV and NPV) will be included (or if they provide sufficient data to calculate these outcomes). Two reviewers will independently assess articles for inclusion, extract data using a piloted tool and assess risk of bias using the QUADAS-2 tool. The feasibility of a meta-analysis will be determined by assessing heterogeneity across the studies, grouped by index device, diagnostic threshold and setting. If a meta-analysis is feasible for any index device, pooled sensitivity and specificity will be calculated using a random effect model and presented in forest plots. DISCUSSION: The findings of our review will provide a comprehensive synthesis of the diagnostic accuracy of available digital technologies capable for diagnosing AF. Thus, this review will aid in the identification of which devices could be further trialed and implemented, particularly in a LMIC setting, to improve the early diagnosis of AF.

Effectiveness and safety in non-valvular atrial fibrillation patients switching from warfarin to direct oral anticoagulants in US healthcare claims.

INTRODUCTION: There is a paucity of real-world studies examining the risks of stroke/systemic embolism (SE) and major bleeding (MB) among non-valvular atrial fibrillation (NVAF) patients switching from warfarin to a direct oral anticoagulant (DOAC). This retrospective study was conducted to compare the stroke/SE and MB risks between patients switched from warfarin to apixaban, dabigatran, or rivaroxaban in real-world clinical practice. MATERIALS AND METHODS: This study used data from four United States commercial claims databases from January 1, 2012 to June 30, 2019. The study population included NVAF patients initially treated with warfarin and switched to apixaban, dabigatran, or rivaroxaban within 90 days of their warfarin prescription ending. Patients were matched 1:1 between the DOACs in each database using propensity scores and then pooled for the final analysis. Cox proportional hazards models were used to calculate the risk of stroke/SE and MB. RESULTS AND CONCLUSIONS: The final population consisted of 2,611 apixaban-dabigatran, 12,165 apixaban-rivaroxaban, and 2,672 dabigatran-rivaroxaban pairs. Apixaban vs. dabigatran was associated with a lower risk of stroke/SE (hazard ratio [HR]: 0.61; 95% confidence interval [CI]: 0.39-0.96) and MB (HR: 0.67; 95% CI: 0.50-0.91). Apixaban vs. rivaroxaban was associated with a similar risk of stroke/SE (HR: 0.88; 95% CI: 0.73-1.07) and a lower risk of MB (HR: 0.60; 95% CI: 0.52-0.68). There was no significant difference in either risk between dabigatran and rivaroxaban. These results provide important insights into how the risks of stroke/SE and MB for NVAF patients vary when switching from warfarin to different DOACs.

Prognostic implications of heart failure stages among Chinese community populations: insight from a nationwide population-based study.

Background: In light of high burden of heart failure (HF) in China, studies of prognostic implication of HF stages are important. We aimed to evaluate the relationship between HF stages and mortality risk in Chinese community populations. Methods: Nationwide representative populations aged ≥35 years (n = 23,284, mean age 56.9 years, women 53.2%) were enrolled from 2012 to 2016. According to the international HF guidelines, participants were divided into stage A, B and C, and those who did not qualify these stages were categorized as apparently-healthy group. Association between HF stages and all-cause, cardiovascular [CV] and non-CV death was evaluated using multivariable-adjusted Cox proportional regression analysis. Findings: During a median follow-up of 4.7 years (109,902.8 person-years), 1314 deaths occurred. Age-adjusted incidence rate of all-cause death was 5.3 in apparently-healthy, 7.8 in stage A, 8.6 in stage B and 24.6 in stage C groups per 1000 person-years. In reference to apparently-healthy group, adjusted hazard ratio for all-cause death was 1.90 (95% CI: 1.47-2.45), 2.43 (95% CI: 1.89-3.13) and 6.40 (95% CI: 4.56-8.99) for stage A, B and C. Advancing HF stages were associated with increasing risks for all-cause, CV and non-CV death (P-trend <0.05). For all-cause death, population attributable fraction due to stage A, B and C were 21.2%, 33.4% and 4.9%, accounting for 1,933,385, 3,045,993 and 446,867 deaths in China in 2018. Interpretation: Advancing HF stages were associated with increasing risk mortality. Development and implementation of early screening and targeted interventions are urgently needed to reduce HF burdens in China. Funding: This work was supported by the Chinese Academy of Medical Sciences Innovation Fund for Medical Sciences (grant 2017-I2M-1-004), the Projects in the Chinese National Science & Technology Pillar Program during the Twelfth Five-year Plan Period (No.: 2011BAI11B01), and the Project Entrusted by the National Health Commission of the People's Republic of China (NHC2020-609).

2024 Chinese expert consensus guidelines on the diagnosis and treatment of Atrial Fibrillation in the Elderly. Executive Summary.

The consensus guidelines of the Geriatric Society of Chinese Medical Association (GSCMA) on the management of atrial fibrillation (AF) in the elderly was first published in 2011 and updated in 2016, with endorsement by Chinese Society of Geriatric Health Medicine (CSGHM). Since then, many important studies regarding the screening and treatment in the elderly population have been reported, necessitating this updated expert consensus guidelines. The writing committee members comprehensively reviewed updated evidence pertaining to elderly patients with AF, and formulated this 2024 update. The highlighted issues focused on the following: screening for AF, geriatric comprehensive assessment, use of the Atrial fibrillation Better Care (ABC) pathway for the elderly patients, and special clinical settings related to elderly patients with AF. New recommendations addressing smart technology facilitated AF screening, ABC pathway based management and optimal anticoagulation were developed, with a focus on the elderly.

Combination therapy of beta-blockers and digoxin is associated with increased risk of major adverse cardiovascular events and all-cause mortality in patients with atrial fibrillation: a report from the GLORIA-AF registry.

The effect of digoxin and beta-blockers on cardiovascular outcomes and mortality remains unclear. The study aimed to determine differences in cardiovascular (CV) outcomes and death rates among patients with atrial fibrillation (AF) who were prescribed with beta-blockers, digoxin or combination therapy. Data from phase II/III of the prospective Global Registry on Long-Term Oral Anti-thrombotic Treatment in Patients with Atrial Fibrillation (GLORIA-AF) were analysed. The risk of major cardiovascular events (MACE) and death among patients with different prescriptions using COX proportional hazard regression was considered. Propensity score (PS) matching and weighting were further used to adjust for potential confounders of prescription use. A total of 14,201 patients [median age: 71.0 (IQR 64.0-77.0) years; 46.2% female] were recruited. After a median follow-up of 3.0 (IQR 2.4-3.1) years, 864 MACE, and 988 all-cause deaths were recorded. The incidence rate (IR) of MACE was 22.4 (95%CI 21.0-24.0) per 1000 person-years, while the IR of all-cause death was 25.4 (95%CI 23.8-27.0) per 1000 person-years. After multivariate adjustment with Cox regression, the risk of MACE (HR 1.35, 95% CI 1.09-1.68) and the risk of all-cause death (HR 1.28, 95%CI 1.04-1.57) were significantly higher in the combination therapy group, compared to the beta-blockers alone group. The risks of MACE and all-cause death remained significant in both PS matched and PS weighted cohort Among AF patients, combination therapy of beta-blockers and digoxin was associated with higher risks of MACE and all-cause death compared to beta-blockers alone.

Scottish Intercollegiate Guidelines Network (SIGN) Guidance on Dementia. The investigation of suspected dementia (SIGN 168) with focus on biomarkers.

This is an executive summary of the recent guidance produced by the SIGN dementia guideline group with regards to the investigation of suspected dementia. This is a sub-section of the broader SIGN 168 guideline released in November 2023. The guideline group included clinicians with expertise in Old Age Psychiatry, Neurology, Radiology and Nuclear Medicine supported by colleagues from the SIGN and Healthcare Improvement Scotland (HIS) teams. There was representation from carers and support organisations with experience of dementia, to ensure the recommendations were appropriate from the perspective of the people being assessed for possible dementia and their carers. As the 2018 National Institute for Health and Clinical Excellence (NICE) dementia review, included a review of the evidenced investigation of dementia, the SIGN guideline development group decided to focus on a review on the up to date evidence regarding the role of imaging and fluid biomarkers in the diagnosis of dementia. In order to give context to the consideration of more advanced diagnostic biomarker investigations, the guideline and this summary includes the NICE guidance on the use of standard investigations as well as more specialist investigations. The evidence review supports consideration of the use of structural imaging, nuclear medicine imaging and established Alzheimer's cerebrospinal fluid (CSF) biomarkers (amyloid and tau) in the diagnosis of dementia. Although routine use of amyloid PET imaging was not recommended, its potential use, under specialist direction, in patients with atypical or young onset presentations of suspected Alzheimer's dementia was included as a clinical good practice point.

Relation of changes in ABC pathway compliance status to clinical outcomes in patients with atrial fibrillation: A report from the COOL-AF registry.

AIM: The Atrial fibrillation Better Care (ABC) pathway provides a framework for holistic care management of atrial fibrillation (AF) patients. This study aimed to determine the impact of changes in compliance to ABC pathway management on clinical outcomes. METHODS: This is a prospective multicenter AF registry. Patients with non-valvular AF were enrolled and follow-up for 3 years. Baseline and follow-up compliance to the ABC pathway was assessed. The main outcomes were all-cause death, ischemic stroke/systemic embolism (SSE), major bleeding, and heart failure. RESULTS: There studied 3096 patients (mean age 67.6 ± 11.1 years, 41.8% female). Patients were categorized into 4 groups: Group 1: ABC compliant at baseline and 1 year [n = 1022 (33.0%)]; Group 2: ABC non-compliant at baseline but compliant at 1 year [n = 307 (9.9%)]; Group 3: ABC compliant at baseline and non-compliant at 1 year [n = 312 (10.1%)]; and Group 4: ABC non-compliant at baseline and also at 1 year [n = 1455 (47.0%)]. The incidence rates (95% confidence intervals, CI) of the composite outcome for Group 1 to 4 were 5.56 (4.54-6.74), 7.42 (5.35-10.03), 9.74 (7.31-12.70), and 11.57 (10.28-12.97), respectively. With Group 1 as a reference, Group 2-4 had hazard ratios (95% CI) of the composite outcome of 1.32 (0.92-1.89), 1.75 (1.26-2.43), and 2.07 (1.65-2.59), respectively. CONCLUSION: Re-evaluation of compliance status of the ABC pathway management is needed to optimize integrated care management and improve clinical outcomes. AF patients who were ABC pathway compliant at baseline and also at follow-up had the best clinical outcomes.

Association between types of antihypertensive medication and the risk of atrial fibrillation: a nationwide population study.

Background: Patients with hypertension are at a high risk of atrial fibrillation (AF). Recent research has indicated the varying effects of antihypertensive medications on developing AF. Objectives: We investigated the relationship between different types of antihypertensive medications and the risk of AF occurrence. Methods: We analyzed data from 113,582 subjects with national health screening examinations between 2009 and 2014. The study population was categorized according to antihypertensive medication type. The primary outcome was the incidence of AF. Results: Among 113,582 subjects (mean age 59.4 ± 12.0 years, 46.7% men), 93,557 received monotherapy [angiotensin receptor blockers (ARB), angiotensin-converting enzyme inhibitors (ACEi), beta-blockers, calcium channel blockers (CCB), or diuretics], while 34,590 received combination therapy (ARB/beta-blockers, ARB/CCB, ARB/diuretics, or ARB/CCB/diuretics). During a mean follow-up duration of 7.6 ± 2.1 years, 3.9% of patients were newly diagnosed with AF. In monotherapy, ACEi and CCB had similar AF risks as ARB, while beta-blockers and diuretics showed higher AF risks than ARB. In combination therapy, ARBs/CCBs and ARBs/diuretics had the lowest AF risk, whereas ARBs/beta-blockers had the highest compared to ARB/CCB. Among the specific ARBs, the AF risk varied insignificantly, except for telmisartan and candesartan. Conclusions: In hypertensive patients receiving monotherapy, ACEi and CCB showed a similar AF risk as ARBs, while beta-blockers and diuretics were associated with a higher risk. Among those receiving combination therapy, ARBs/CCBs and ARBs/diuretics had the lowest AF risk, whereas ARBs/beta-blockers showed the highest risk. Various types of ARBs have different associations with AF risk.

Low-dose azithromycin prophylaxis in patients with atrial fibrillation and chronic obstructive pulmonary disease.

Low-dose azithromycin prophylaxis is associated with improved outcomes in people suffering frequent exacerbations of chronic obstructive pulmonary disease (COPD), but the use of macrolides in patients with cardiovascular disease has been debated. To investigate the risk of adverse events after COPD exacerbations in patients with atrial fibrillation (AF) treated with azithromycin prophylaxis. Retrospective cohort study within the TriNetX Platform, including AF patients with COPD exacerbations. Risks of primary and secondary outcomes were recorded up to 30 days post-COPD exacerbations and compared between azithromycin users and azithromycin non-users. The primary outcomes were the risks for a composite of (1) cardiovascular (all-cause death, heart failure, ventricular arrhythmias, ischemic stroke, myocardial infarction, and cardiac arrest), and (2) hemorrhagic events (intracranial hemorrhage (ICH), and gastro-intestinal bleeding). Cox-regression analyses compared outcomes between groups after propensity score matching (PSM). After PSM, azithromycin users (n = 2434, 71 ± 10 years, 49% females) were associated with a lower 30-day risk of post-exacerbation cardiovascular (HR 0.67, 95% CI 0.61-0.73) and hemorrhagic composite outcome (HR 0.45, 95% CI 0.32-0.64) compared to azithromycin non-users (n = 2434, 72 ± 11 years, 51% females). The beneficial effect was consistent for each secondary outcomes, except ICH. On sensitivity analyses, the reduced risk of adverse events in azithromycin users was irrespective of smoking status, exacerbation severity, and type of oral anticoagulation. Azithromycin prophylaxis is associated with a lower risk of all-cause death, thrombotic and hemorrhagic events in AF patients with COPD. The possible role of azithromycin prophylaxis as part of the integrated care management of AF patients with COPD needs further study.

Continuous infusion versus bolus injection of loop diuretics for acute heart failure.

BACKGROUND: Acute heart failure (AHF) is new onset of, or a sudden worsening of, chronic heart failure characterised by congestion in about 95% of cases or end-organ hypoperfusion in 5% of cases. Treatment often requires urgent escalation of diuretic therapy, mainly through hospitalisation. This Cochrane review evaluated the efficacy of intravenous loop diuretics strategies in treating AHF in individuals with New York Heart Association (NYHA) classification III or IV and fluid overload. OBJECTIVES: To assess the effects of intravenous continuous infusion versus bolus injection of loop diuretics for the initial treatment of acute heart failure in adults. SEARCH METHODS: We identified trials through systematic searches of bibliographic databases and in clinical trials registers including CENTRAL, MEDLINE, Embase, CPCI-S on the Web of Science, ClinicalTrials.gov, the World Health Organization (WHO) International Clinical Trials Registry platform (ICTRP), and the European Union Trials register. We conducted reference checking and citation searching, and contacted study authors to identify additional studies. The latest search was performed on 29 February 2024. SELECTION CRITERIA: We included randomised controlled trials (RCTs) involving adults with AHF, NYHA classification III or IV, regardless of aetiology or ejection fraction, where trials compared intravenous continuous infusion of loop diuretics with intermittent bolus injection in AHF. We excluded trials with chronic stable heart failure, cardiogenic shock, renal artery stenosis, or end-stage renal disease. Additionally, we excluded studies combining loop diuretics with hypertonic saline, inotropes, vasoactive medications, or renal replacement therapy and trials where diuretic dosing was protocol-driven to achieve a target urine output, due to confounding factors. DATA COLLECTION AND ANALYSIS: Two review authors independently screened papers for inclusion and reviewed full-texts. Outcomes included weight loss, all-cause mortality, length of hospital stay, readmission following discharge, and occurrence of acute kidney injury. We performed risk of bias assessment and meta-analysis where data permitted and assessed certainty of the evidence. MAIN RESULTS: The review included seven RCTs, spanning 32 hospitals in seven countries in North America, Europe, and Asia. Data collection ranged from eight months to six years. Following exclusion of participants in subgroups with confounding treatments and different clinical settings, 681 participants were eligible for review. These additional study characteristics, coupled with our strict inclusion and exclusion criteria, improve the applicability of the body of the evidence as they reflect real-world clinical practice. Meta-analysis was feasible for net weight loss, all-cause mortality, length of hospital stay, readmission, and acute kidney injury. Literature review and narrative analysis explored daily fluid balance; cardiovascular mortality; B-type natriuretic peptide (BNP) change; N-terminal-proBNP change; and adverse incidents such as ototoxicity, hypotension, and electrolyte imbalances. Risk of bias assessment revealed two studies with low overall risk, four with some concerns, and one with high risk. All sensitivity analyses excluded trials at high risk of bias. Only narrative analysis was conducted for 'daily fluid balance' due to diverse data presentation methods across two studies (169 participants, the evidence was very uncertain about the effect). Results of narrative analysis varied. For instance, one study reported higher daily fluid balance within the first 24 hours in the continuous infusion group compared to the bolus injection group, whereas there was no difference in fluid balance beyond this time point. Continuous intravenous infusion of loop diuretics may result in mean net weight loss of 0.86 kg more than bolus injection of loop diuretics, but the evidence is very uncertain (mean difference (MD) 0.86 kg, 95% confidence interval (CI) 0.44 to 1.28; 5 trials, 497 participants; P < 0.001, I2 = 21%; very low-certainty evidence). Importantly, sensitivity analysis excluding trials with high risk of bias showed there was insufficient evidence for a difference in bodyweight loss between groups (MD 0.70 kg, 95% CI -0.06 to 1.46; 3 trials, 378 participants; P = 0.07, I2 = 0%). There may be little to no difference in all-cause mortality between continuous infusion and bolus injection (risk ratio (RR) 1.53, 95% CI 0.81 to 2.90; 5 trials, 530 participants; P = 0.19, I2 = 4%; low-certainty evidence). Despite sensitivity analysis, the direction of the evidence remained unchanged. No trials measured cardiovascular mortality. There may be little to no difference in the length of hospital stay between continuous infusion and bolus injection of loop diuretics, but the evidence is very uncertain (MD -1.10 days, 95% CI -4.84 to 2.64; 4 trials, 211 participants; P = 0.57, I2 = 88%; very low-certainty evidence). Sensitivity analysis improved heterogeneity; however, the direction of the evidence remained unchanged. There may be little to no difference in the readmission to hospital between continuous infusion and bolus injection of loop diuretics (RR 0.85, 95% CI 0.63 to 1.16; 3 trials, 400 participants; P = 0.31, I2 = 0%; low-certainty evidence). Sensitivity analysis continued to show insufficient evidence for a difference in the readmission to hospital between groups. There may be little to no difference in the occurrence of acute kidney injury as an adverse event between continuous infusion and bolus injection of intravenous loop diuretics (RR 1.02, 95% CI 0.70 to 1.49; 3 trials, 491 participants; P = 0.92, I2 = 0%; low-certainty evidence). Sensitivity analysis continued to show that continuous infusion may make little to no difference on the occurrence of acute kidney injury as an adverse events compared to the bolus injection of intravenous loop diuretics. AUTHORS' CONCLUSIONS: Analysis of available data comparing two delivery methods of diuretics in acute heart failure found that the current data are insufficient to show superiority of one strategy intervention over the other. Our findings were based on trials meeting stringent inclusion and exclusion criteria to ensure validity. Despite previous reviews suggesting advantages of continuous infusion over bolus injections, our review found insufficient evidence to support or refute this. However, our review, which excluded trials with clinical confounders and RCTs with high risk of bias, offers the most robust conclusion to date.

Plasma Biomarkers for Hypertension-Mediated Organ Damage Detection: A Narrative Review.

Hypertension (HT) is a disease that poses a serious threat to human health, mediating organ damage such as the cardiovascular (CV) system, kidneys, central nervous system (CNS), and retinae, ultimately increasing the risk of death due to damage to the entire vascular system. Thus, the widespread prevalence of hypertension brings enormous health problems and socioeconomic burdens worldwide. The goal of hypertension management is to prevent the risk of hypertension-mediated organ damage and excess mortality of cardiovascular diseases. To achieve this goal, hypertension guidelines recommend accurate monitoring of blood pressure and assessment of associated target organ damage. Early identification of organ damage mediated by hypertension is therefore crucial. Plasma biomarkers as a non-invasive test can help identify patients with organ damage mediated by hypertension who will benefit from antihypertensive treatment optimization and improved prognosis. In this review, we provide an overview of some currently available, under-researched, potential plasma biomarkers of organ damage mediated by hypertension, looking for biomarkers that can be detected by simple testing to identify hypertensive patients with organ damage, which is of great significance in clinical work. Natriuretic peptides (NPs) can be utilized as a traditional biomarker to detect hypertension-mediated organ damage, especially for heart failure. Nevertheless, we additionally may need to combine two or more plasma biomarkers to monitor organ damage in the early stages of hypertension.

Modifiable lifestyle factors and lifetime risk of atrial fibrillation: longitudinal data from the Korea NHIS-HealS and UK Biobank cohorts.

BACKGROUND: The reason for higher incidence of atrial fibrillation (AF) in Europe compared with East Asia is unclear. We aimed to investigate the association between modifiable lifestyle factors and lifetime risk of AF in Europe and East Asia, along with race/ethnic similarities and disparities. METHODS: 1:1 propensity score matched pairs of 242,763 East Asians and 242,763 White Europeans without AF were analyzed. Modifiable lifestyle factors considered were blood pressure, body mass index, cigarette smoking, diabetes, alcohol consumption, and physical activity, categorized as non-adverse or adverse levels. Lifetime risk of AF was estimated from the index age of 45 years to the attained age of 85 years, accounting for the competing risk of death. RESULTS: The overall lifetime risk of AF was higher in White Europeans than East Asians (20.9% vs 15.4%, p < 0.001). The lifetime risk of AF was similar between the two races in individuals with non-adverse lifestyle factor profiles (13.4% vs 12.9%, p = 0.575), whereas it was higher in White Europeans with adverse lifestyle factor profiles (22.1% vs 15.8%, p < 0.001). The difference in the lifetime risk of AF between the two races increased as the burden of adverse lifestyle factors worsened (1 adverse lifestyle factor; 4.3% to ≥ 3 adverse lifestyle factors; 11.2%). Compared with East Asians, the relative risk of AF in White Europeans was 23% and 62% higher for one (hazard ratio [HR] 1.23, 95% confidence interval [CI] 1.16-1.29) and ≥ 3 adverse lifestyle factors (HR 1.62, 95% CI 1.51-1.75), respectively. CONCLUSIONS: The overall higher lifetime risk of AF in White Europeans compared with East Asians might be attributable to adverse lifestyle factors. Adherence to healthy lifestyle factors was associated with the lifetime risk of AF of about 1 in 8 regardless of race/ethnicity.

Lipid-based insulin-resistance markers predict cardiovascular events in metabolic dysfunction associated steatotic liver disease.

BACKGROUND: Insulin resistance (IR) is the cornerstone of Metabolic Dysfunction Associated Steatotic Liver Disease (MASLD), pathophysiologically being the key link between MASLD, metabolic disorders, and cardiovascular (CV) diseases. There are no prospective studies comparing the predictive values of different markers of insulin resistance (IR) in identifying the presence of MASLD and the associated risk of cardiovascular events (CVEs). METHODS: Post hoc analysis of the prospective Plinio Study, involving dysmetabolic patients evaluated for the presence of MASLD. The IR markers considered were Homeostatic Model Assessment for IR (HOMA-IR), Triglycerides-Glycemia (TyG) index, Triglycerides to High-Density Lipoprotein Cholesterol ratio (TG/HDL-C), Lipid Accumulation Product (LAP) and Visceral Adiposity Index (VAI). Receiver operative characteristic (ROC) analyses were performed to find the optimal cut-offs of each IR marker for detecting MASLD and predicting CVEs in MASLD patients. Logistic and Cox multivariable regression analyses were performed, after dichotomizing the IR markers based on the optimal cut-offs, to assess the factors independently associated with MASLD and the risk of CVEs. RESULTS: The study included 772 patients (age 55.6 ± 12.1 years, 39.4% women), of whom 82.8% had MASLD. VAI (Area Under the Curve [AUC] 0.731), TyG Index (AUC 0.723), and TG/HDL-C ratio (AUC: 0.721) predicted MASLD but was greater with HOMA-IR (AUC: 0.792) and LAP (AUC: 0.787). After a median follow-up of 48.7 (25.4-75.8) months, 53 MASLD patients experienced CVEs (1.8%/year). TyG index (AUC: 0.630), LAP (AUC: 0.626), TG/HDL-C (AUC: 0.614), and VAI (AUC: 0.590) demonstrated comparable, modest predictive values in assessing the CVEs risk in MASLD patients. CONCLUSION: In dysmetabolic patients HOMA-IR and LAP showed the best accuracy in detecting MASLD. The possible use of lipid-based IR markers in stratifying the CV risk in patients with MASLD needs further validation in larger cohorts.
