Front Cardiovasc Med 2023; 10:1339203. [PMID: 38204798 PMCID: PMC10777843 DOI: 10.3389/fcvm.2023.1339203] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2023] [Accepted: 12/11/2023] [Indexed: 01/12/2024] Open
Abstract
Background Heart failure (HF) is a global health challenge. The perturbations in fluid and electrolyte equilibrium, particularly the compromised sodium balance associated with HF lead to high mortality rates. Hence, elucidating the correlation between serum sodium levels and the prognosis of HF is of paramount importance. This study aimed to conduct a comprehensive meta-analysis to thoroughly investigate the interplay between hyponatremia and the prognostic outlook of individuals with HF. Methods A comprehensive search of bibliographic databases including PubMed, Embase, and the Cochrane Central Register of Controlled Trials was conducted to identify relevant observational studies examining the association between hyponatremia and prognosis of HF. Data extraction, synthesis, and assessment of risk of bias were conducted. Meta-analytic methods, sensitivity analyses, and heterogeneity test were employed as appropriate to synthesize the data. Results A total of 43,316 patients with HF were included spanning 25 selected studies. The pooled data revealed a notable association between hyponatremia and elevated risks across short and long-term mortality of HF. Specifically, hyponatremia was found to significantly increase the likelihood of all-cause mortality (Hazard ratio [HR] = 1.94, 95% confidence interval [CI]: 1.78-2.12); 1-year mortality (HR = 1.67, 95%CI: 1.46-1.90); 30-day mortality (HR = 2.03, 95%CI: 1.73-2.25); cardiac mortality (HR = 2.11, 95%CI: 1.81-2.46); and in-hospital mortality (HR = 1.64, 95%CI: 1.15-2.34). Conclusion Our meta-analysis emphasizes the significant impact of hyponatremia on mortality in the HF patient population, highlighting the critical importance of maintaining stable serum sodium levels in HF management.

Point-of-care echocardiography of the right heart improves acute heart failure risk stratification for low-risk patients: The REED-AHF prospective study. Acad Emerg Med 2022; 29:1306-1319. [PMID: 36047646 PMCID: PMC9671834 DOI: 10.1111/acem.14589] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2022] [Revised: 08/23/2022] [Accepted: 08/26/2022] [Indexed: 01/25/2023]
Abstract
OBJECTIVES Validated acute heart failure (AHF) clinical decision instruments (CDI) insufficiently identify low-risk patients meriting consideration of outpatient treatment. While pilot data show that tricuspid annulus plane systolic excursion (TAPSE) is associated with adverse events, no AHF CDI currently incorporates point-of-care echocardiography (POCecho). We evaluated whether TAPSE adds incremental risk stratification value to an existing CDI. METHODS Prospectively enrolled patients at two urban-academic EDs had POCechos obtained before or <1 h after first intravenous diuresis, positive pressure ventilation, and/or nitroglycerin. STEMI and cardiogenic shock were excluded. AHF diagnosis was adjudicated by double-blind expert review. TAPSE, with an a priori cutoff of ≥17 mm, was our primary measure. Secondary measures included eight additional right heart and six left heart POCecho parameters. STRATIFY is a validated CDI predicting 30-day death/cardiopulmonary resuscitation, mechanical cardiac support, intubation, new/emergent dialysis, and acute myocardial infarction or coronary revascularization in ED AHF patients. Full (STRATIFY + POCecho variable) and reduced (STRATIFY alone) logistic regression models were fit to calculate adjusted odds ratios (aOR), category-free net reclassification index (NRIcont ), ΔSensitivity (NRIevents ), and ΔSpecificity (NRInonevents ). Random forest assessed variable importance. To benchmark risk prediction to standard of care, ΔSensitivity and ΔSpecificity were evaluated at risk thresholds more conservative/lower than the actual outcome rate in discharged patients. RESULTS A total of 84/120 enrolled patients met inclusion and diagnostic adjudication criteria. Nineteen percent experiencing the primary outcome had higher STRATIFY scores compared to those event free (233 vs. 212, p = 0.009). Five right heart (TAPSE, TAPSE/PASP, TAPSE/RVDD, RV-FAC, fwRVLS) and no left heart measures improved prediction (p < 0.05) adjusted for STRATIFY. Right heart measures also had higher variable importance. TAPSE ≥ 17 mm plus STRATIFY improved prediction versus STRATIFY alone (aOR 0.24, 95% confidence interval [CI] 0.06-0.91; NRIcont 0.71, 95% CI 0.22-1.19), and specificity improved by 6%-32% (p < 0.05) at risk thresholds more conservative than the standard-of-care benchmark without missing any additional events. CONCLUSIONS TAPSE increased detection of low-risk AHF patients, after use of a validated CDI, at risk thresholds more conservative than standard of care.

Hyponatremia in the emergency department. Am J Emerg Med 2022; 60:1-8. [PMID: 35870366 DOI: 10.1016/j.ajem.2022.07.023] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2022] [Revised: 07/06/2022] [Accepted: 07/07/2022] [Indexed: 11/20/2022] Open
Abstract
Hyponatremia, defined as a serum sodium <135 mmol/L, is frequently encountered in patients presenting to the emergency department. Symptoms are often unspecific and include a recent history of falls, weakness and vertigo. Common causes of hyponatremia include diuretics, heart failure as well as Syndrome of Inappropriate Antidiuresis (SIAD) and correct diagnosis can be challenging. Emergency treatment of hyponatremia should be guided by presence of symptoms and focus on distinguishing between acute and chronic hyponatremia.

Abstract
BACKGROUND Hyponatremia is a well-established marker of adverse outcomes in chronic heart failure (HF) but not well studied in patients with left ventricular assist device (LVAD). METHODS This is a retrospective study, single center study of HM3 [Abbott, USA] LVAD implants. We divided our population based on their sodium prior to LVAD implantation - hyponatremia if <135 mEq/L and normal sodium if 135 - 145 mEq/L. We compared postoperative and long-term outcomes. RESULTS A total of 195 patients were included, preimplant hyponatremia was present in 40% with a sodium of 132.1±2.1 vs. 137.8±1.9 mEq/L in the normal sodium group. No differences were observed in the postoperative or long-term outcomes. CONCLUSION Preimplant hyponatremia was not associated with mortality or HF admissions, likely due to adequate left ventricular unloading and resolution of the mechanisms that lead to hyponatremia. These results suggest that optimization of mild hyponatremia may not be critical and should not delay LVAD placement.

Abstract
Sodium is a physiologically essential nutrient, but excessive intake is linked to the increased risk of various chronic diseases, particularly cardiovascular. It is, therefore, necessary to accomplish an evidence-based approach and establish the Korean Dietary Reference Intakes (KDRIs) index, to identify both the nutritional adequacy and health effects of sodium. This review presents the rationale for and the process of revising the KDRIs for sodium and, more importantly, establishing the sodium Chronic Disease Risk Reduction Intake (CDRR) level, which is a new specific set of values for chronic disease risk reduction. To establish the 2020 KDRIs for dietary sodium, the committee conducted a systematic literature review of the intake–response relationships between the selected indicators for sodium levels and human chronic diseases. In this review, 43 studies published from January 2014 to December 2018, using databases of PubMed and Web of Science, were finally included for evaluating the risk of bias and strength of evidence (SoE). We determined that SoE of the relationship between dietary sodium and cardiovascular diseases, cerebrovascular disease, and hypertension, was moderate to strong. However, due to insufficient scientific evidence, we were unable to establish the estimated average requirement and the recommended nutrient intake for dietary sodium. Therefore, the adequate intake of sodium for adults was established to be 1,500 mg/day, whereas the CDRR for dietary sodium was established at 2,300 mg/day for adults. Intake goal for dietary sodium established in the 2015 KDRIs instead of the tolerable upper intake level was not presented in the 2020 KDRIs. For the next revision of the KDRIs, there is a requirement to pursue further studies on nutritional adequacy and toxicity of dietary sodium, and their associations with chronic disease endpoint in the Korean population.

Blood Purif 2021; 51:251-259. [PMID: 34130280 DOI: 10.1159/000515826] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2020] [Accepted: 03/11/2021] [Indexed: 11/19/2022]
Abstract
INTRODUCTION The aim of this study was to clarify the efficacy of early goal-directed renal replacement therapy (GDRRT) for treatment of cardiorenal syndrome (CRS) patients after acute decompensated heart failure (ADHF). METHODS In the retrospective, observational study, we enrolled 54 patients in the early GDRRT group and 63 patients in the late GDRRT group. Baseline characteristics, clinical data at initiation renal replacement therapy time, and the clinical outcome were collected and several parameters were compared and analyzed between 2 groups. RESULTS The urine volume at GDRRT initiation time in the early group was higher than that in the late GDRRT group (1,060.3 ± 332.1 vs. 300.5 ± 148.3 mL, p < 0.001). Hemodynamic parameters such as mean artery pressure were higher (70.06 ± 32.99 vs. 54.34 ± 40.88 mm Hg, p = 0.012), the heart rate was slower (80.17 ± 15.26 vs. 99.21 ± 25.45 bpm, p = 0.002), and the diameter of inferior vena cava was narrower (22.00 ± 1.91 vs. 25.77 ± 5.5 mm, p = 0.04) in early GDRRT. Primary end point was inhospital all-cause mortality and cardiovascular mortality, which was obviously lower in the early GDRRT group (respectively 24.1 vs. 60.3%, p = 0.002 and 20.3 vs. 50.8%, p = 0.005). The second end point of kidney recovery in the early GDRRT group was much better than that in the latter GDRRT group (p = 0.018). Moreover, urine volume after GDRRT of the early group was more significant than that of the late group (1,432 ± 172 vs. 702 ± 183 mL, p = 0.005). CONCLUSION This study clarified the effectiveness of the early GDRRT strategy in ADHF patients suffered from CRS, which reduced inhospital mortality and improved the urine output and clinical kidney recovery outcome.

Improvement of hyponatremia is associated with lower mortality risk in patients with acute decompensated heart failure: a meta-analysis of cohort studies. Heart Fail Rev 2020; 24:209-217.

Abstract
Hyponatremia at admission is predictive of poor prognosis in patients with acute decompensated heart failure (ADHF). We performed a meta-analysis of cohort studies to evaluate whether improvement of hyponatremia is associated with improved survival in patients with ADHF and hyponatremia. Relevant studies were identified through systematic search of PubMed and Embase. A random-effect model was used to pool the results. Predefined subgroup analyses were performed to explore the source of heterogeneity. Five thousand seven hundred fourteen patients with ADHF and hyponatremia from eight cohort studies were included. Results showed that improvement of hyponatremia during hospitalization was associated with lower risk of all-cause mortality (RR = 0.65, 95% CI 0.53 to 0.80, p < 0.001) as compared with those without improvement of hyponatremia. Results of subgroup analyses indicated that improvement of hyponatremia was associated with more remarkable changes of short-term (within 3 months after discharge) mortality (RR = 0.54) as compared with long-term mortality (RR = 0.74). Other factors such as study design, sample size, and heart failure subtypes did not affect the association. This was further confirmed by the meta-analysis of studies with multivariate analysis, which also suggested an association between improved hyponatremia and lower risk of all-cause mortality in ADHF patients (adjusted RR = 0.63, 95% CI 0.43 to 0.92, p = 0.02; I2 = 63%). These results suggested that improvement of hyponatremia in ADHF patients is associated with lower mortality risk during follow-up, particularly for the short-term mortality.

Paradigm Shifts of Heart Failure Therapy: Do We Need Another Paradigm? ACTA ACUST UNITED AC 2020; 2:145-156.

Abstract
Heart failure (HF) is a progressive condition with intermittent acute decompensation leading to poor prognosis despite established guideline-directed therapy. A paradigm of HF therapy has been shifted over last four decades. Until the early 1970s, HF was empirically managed, then was managed with the hemodynamic concept until the early 1980s. According to the results of large randomized clinical trials, HF therapy has been shifted to the neurohormonal paradigm since the late 1980s until recently. Korean Acute Heart Failure (KorAHF) registry is a multi-center registry that recruited a total of 5625 admitted patients with acute HF from 2011 to 2014 and followed until 2019. Through KorAHF registry, we could obtain invaluable information or messages in various fields such as epidemiology, clinical characteristics, and treatment of acute HF in Korea and also had opportunities to fill the gap between guideline-directed care and real-world practice. Considering significant unmet needs in HF therapy even at this moment, we do need another paradigm shift for HF therapy, such as molecular and regenerative paradigm using gene, stem cells, mechanical support as well as novel pharmacological agents.
