Non-cardiac comorbidities in heart failure: an update on diagnostic and management strategies.

Managing non-cardiac comorbidities in heart failure (HF) requires a tailored approach that addresses each patient's specific conditions and needs. Regular communication and coordination among healthcare providers is crucial to providing the best possible care for these patients. Poorly controlled hypertension contributes to left ventricular remodeling and diastolic dysfunction, emphasizing the importance of optimal blood pressure control while avoiding adverse effects. Among HF patients with diabetes, SGLT2 inhibitors and mineralocorticoid receptor antagonists have shown promise in reducing HF-related morbidity and mortality. Chronic kidney disease exacerbates HF and vice versa, forming the vicious cardiorenal syndrome, so disease-modifying therapies should be maintained in HF patients with comorbid CKD, even with transient changes in kidney function. Anemia in HF patients may be multifactorial, and there is growing evidence for the benefit of intravenous iron supplementation in HF patients with iron deficiency with or without anemia. Obesity, although a risk factor for HF, paradoxically offers a better prognosis once HF is established, though developing treatment strategies may improve symptoms and cardiac performance. In HF patients with stroke and atrial fibrillation, anticoagulation therapy is recommended. Among HF patients with sleep-disordered breathing, continuous positive airway pressure may improve sleep quality. Chronic obstructive pulmonary disease often coexists with HF, and many patients can tolerate cardioselective beta-blockers. Cancer patients with comorbid HF require careful consideration of cardiotoxicity risks associated with cancer therapies. Depression is underdiagnosed in HF patients and significantly impacts prognosis. Cognitive impairment is prevalent in HF patients and impacts their self-care and overall quality of life.

Nonsteroidal Mineralocorticoid Receptor Antagonist Finerenone Improves Diastolic Dysfunction in Preclinical Nondiabetic Chronic Kidney Disease.

BACKGROUND: The mineralocorticoid receptor plays a significant role in the development of chronic kidney disease (CKD) and associated cardiovascular complications. Classic steroidal mineralocorticoid receptor antagonists are a therapeutic option, but their use in the clinic is limited due to the associated risk of hyperkalemia in patients with CKD. Finerenone is a nonsteroidal mineralocorticoid receptor antagonist that has been recently investigated in 2 large phase III clinical trials (FIDELIO-DKD [Finerenone in Reducing Kidney Failure and Disease Progression in Diabetic Kidney Disease] and FIGARO-DKD [Finerenone in Reducing Cardiovascular Mortality and Morbidity in Diabetic Kidney Disease]), showing reductions in kidney and cardiovascular outcomes. METHODS AND RESULTS: We tested whether finerenone improves renal and cardiac function in a preclinical nondiabetic CKD model. Twelve weeks after 5/6 nephrectomy, the rats showed classic signs of CKD characterized by a reduced glomerular filtration rate and increased kidney weight, associated with left ventricular (LV) diastolic dysfunction and decreased LV perfusion. These changes were associated with increased cardiac fibrosis and reduced endothelial nitric oxide synthase activating phosphorylation (ser 1177). Treatment with finerenone prevented LV diastolic dysfunction and increased LV tissue perfusion associated with a reduction in cardiac fibrosis and increased endothelial nitric oxide synthase phosphorylation. Curative treatment with finerenone improves nondiabetic CKD-related LV diastolic function associated with a reduction in cardiac fibrosis and increased cardiac phosphorylated endothelial nitric oxide synthase independently from changes in kidney function. Short-term finerenone treatment decreased LV end-diastolic pressure volume relationship and increased phosphorylated endothelial nitric oxide synthase and nitric oxide synthase activity. CONCLUSIONS: We showed that the nonsteroidal mineralocorticoid receptor antagonist finerenone reduces renal hypertrophy and albuminuria, attenuates cardiac diastolic dysfunction and cardiac fibrosis, and improves cardiac perfusion in a preclinical nondiabetic CKD model.

Reassessing heart failure therapy in Thailand: Patient insights and treatment outcomes from the Thai heart failure registry.

BACKGROUND: This research analyzed the demographics, management, and outcomes of patients with heart failure (HF) in Thailand. METHODS: The Thai Heart Failure Registry prospectively enrolled patients diagnosed with HF from 36 hospitals in Thailand. Follow-up data were recorded at 6, 12, 18, and 24 months. This study primarily focused on two outcomes: mortality and HF-related hospitalizations. RESULTS: The study included 2639 patients aged at least 18. Their mean age was 59.2 ± 14.5 years, and most were male (68.4%). Patients were classified as having HF with reduced ejection fraction (HFrEF, 80.7%), HF with preserved ejection fraction (HFpEF, 9.0%), or HF with mildly reduced ejection fraction (HFmrEF, 10.3%). Guideline-directed medical therapy utilization varied. Beta-blockers had the highest usage (93.2%), followed by mineralocorticoid receptor antagonists (65.7%), angiotensin-converting enzyme inhibitors (39.3%), angiotensin receptor blockers (28.2%), angiotensin receptor-neprilysin inhibitors (16.1%), and sodium-glucose cotransporter-2 inhibitors (8.0%). The study monitored a composite of mortality and HF incidents, revealing incidence rates of 11.74, 12.50, and 8.93 per 100 person-years for the overall, HFrEF, and HFmrEF/HFpEF populations, respectively. CONCLUSIONS: Despite high guideline-directed medical therapy adherence, the Thai Heart Failure Registry data revealed high mortality and recurrent HF rates. These findings underscore limitations in current HF treatment efficacy. The results indicate the need for further investigation and improvements of HF management to enhance patient outcomes.

[Surgical treatment for primary aldosteronism]. / Rôle de la chirurgie dans l'hyperaldostéronisme primaire.

Primary aldosteronism is the most common cause of secondary hypertension in the middle-aged population. A high level of suspicion is required, due to the higher morbidity and mortality associated with damage to target organs (heart, brain, vessels, kidneys) than with essential hypertension. Screening involves 3 phases: detection, confirmation and detection of lateralization if surgery is an option. The choice of treatment will depend on the cause and the patient's wishes and may be either medical (mineralocorticoid receptor antagonists) or surgical (unilateral adrenalectomy). Both treatment options reduce the risk of cardiovascular morbidity and mortality if blood pressure is well controlled.

L'hyperaldostéronisme primaire est la cause la plus fréquente d'hypertension artérielle secondaire dans la population d'âge moyen. Un haut niveau de suspicion doit être de mise en raison d'une morbimortalité liée aux atteintes d'organes cibles (cœur, cerveau, vaisseaux, reins) plus élevée que lors d'hypertension artérielle essentielle. Le dépistage se fait en 3 phases : détection, confirmation et recherche de latéralisation si une chirurgie est envisageable. Le choix du traitement va dépendre de la cause et des désirs du patient et peut être médicamenteux (antagonistes des récepteurs des minéralocorticoïdes) ou chirurgical (surrénalectomie unilatérale). Les deux options thérapeutiques diminuent le risque de morbimortalité cardiovasculaire si la tension artérielle est bien contrôlée.

How Would You Manage This Patient With Type 2 Diabetes and Chronic Kidney Disease? Grand Rounds Discussion From Beth Israel Deaconess Medical Center.

Nearly 15% of U.S. adults have diabetes; type 2 diabetes (T2D) accounts for more than 90% of cases. Approximately one third of all patients with diabetes will develop chronic kidney disease (CKD). All patients with T2D should be screened annually for CKD with both a urine albumin-creatinine ratio and an estimated glomerular filtration rate. Research into strategies to slow the worsening of CKD and reduce renal and cardiovascular morbidity in patients with T2D and CKD has evolved substantially. In 2022, a consensus statement from the American Diabetes Association and the Kidney Disease: Improving Global Outcomes recommended prioritizing the use of sodium-glucose cotransporter-2 inhibitors and metformin and included guidance for add-on therapy with glucagon-like peptide 1 receptors agonists for most patients whose first-line therapy failed. It also recommended nonsteroidal mineralocorticoid receptor antagonists for patients with hypertension that is not adequately controlled with angiotensin-converting enzyme inhibitors or angiotensin-receptor blockers. Here, an endocrinologist and a nephrologist discuss the care of patients with T2D and CKD and how they would apply the consensus statement to the care of an individual patient with T2D who is unaware that he has CKD.

Baseline characteristics of patients with heart failure with mildly reduced or preserved ejection fraction: The FINEARTS-HF trial.

AIMS: To describe the baseline characteristics of participants in the FINEARTS-HF trial, contextualized with prior trials including patients with heart failure (HF) with mildly reduced and preserved ejection fraction (HFmrEF/HFpEF). The FINEARTS-HF trial is comparing the effects of the non-steroidal mineralocorticoid receptor antagonist finerenone with placebo in reducing cardiovascular death and total worsening HF events in patients with HFmrEF/HFpEF. METHODS AND RESULTS: Patients with symptomatic HF, left ventricular ejection fraction (LVEF) ≥40%, estimated glomerular filtration rate ≥ 25 ml/min/1.73 m2, elevated natriuretic peptide levels and evidence of structural heart disease were enrolled and randomized to finerenone titrated to a maximum of 40 mg once daily or matching placebo. We validly randomized 6001 patients to finerenone or placebo (mean age 72 ± 10 years, 46% women). The majority were New York Heart Association functional class II (69%). The baseline mean LVEF was 53 ± 8% (range 34-84%); 36% of participants had a LVEF <50% and 64% had a LVEF ≥50%. The median N-terminal pro-B-type natriuretic peptide (NT-proBNP) was 1041 (interquartile range 449-1946) pg/ml. A total of 1219 (20%) patients were enrolled during or within 7 days of a worsening HF event, and 3247 (54%) patients were enrolled within 3 months of a worsening HF event. Compared with prior large-scale HFmrEF/HFpEF trials, FINEARTS-HF participants were more likely to have recent (within 6 months) HF hospitalization and greater symptoms and functional limitations. Further, concomitant medications included a larger percentage of sodium-glucose cotransporter 2 inhibitors and angiotensin receptor-neprilysin inhibitors than previous trials. CONCLUSIONS: FINEARTS-HF has enrolled a broad range of high-risk patients with HFmrEF and HFpEF. The trial will determine the safety and efficacy of finerenone in this population.

Cost-Effectiveness of Medical Therapy for Heart Failure With Mildly Reduced and Preserved Ejection Fraction.

BACKGROUND: Three medications are now guideline-recommended treatments for heart failure with mildly reduced or preserved ejection fraction (HFmrEF/HFpEF), however, the cost-effectiveness of these agents in combination has yet to be established. OBJECTIVES: The purpose of this study was to determine the cost-effectiveness of mineralocorticoid receptor antagonists (MRA), angiotensin receptor-neprilysin inhibitors (ARNIs), and sodium glucose co-transporter 2 inhibitors (SGLT2is) in individuals with HFmrEF/HFpEF. METHODS: Using a 3-state Markov model, we performed a cost-effectiveness study using simulated cohorts of 1,000 patients with HFmrEF and HFpEF. Treatment with 1-, 2-, and 3-drug combinations was modeled. Based on a United States health care sector perspective, outcome data was used to calculate incremental cost-effectiveness ratios (ICERs) in 2023 United States dollars based on a 30-year time horizon. RESULTS: Treatment with MRA, MRA+SGLT2i, and MRA+SGLT2i+ARNI therapy resulted in an increase in life years of 1.04, 1.58, and 1.80 in the HFmrEF subgroup, respectively, and 0.99, 1.54, and 1.77 in the HFpEF subgroup, respectively, compared with placebo. At a yearly cost of $18, MRA therapy resulted in ICERs of $10,000 per quality-adjusted life year (QALY) in both subgroups. The ICER for the addition of SGLT2i therapy ($4,962 per year) was $113,000 per QALY in the HFmrEF subgroup and $141,000 in the HFpEF subgroup. The addition of ARNI therapy ($5,504 per year) resulted in ICERs >$250,000 per QALY in both subgroups. If SGLT2i and ARNI were available at generic pricing the ICERs become <$10,000 per QALY in both EF subgroups. Outcomes were highly sensitive to assumed benefit in cardiovascular death. CONCLUSIONS: For patients with heart failure, MRA was of high value, SGLT2i was of intermediate value, and ARNI was of low value in both HFmrEF and HFpEF subgroups. For patients with HFmrEF/HFpEF increased use of MRA and SGLT2i therapies should be encouraged and be accompanied with efforts to lower the cost of SGLT2i and ARNI therapies.

Exploring the Mechanism of Cardiorenal Protection with Finerenone Based on Network Pharmacology.

INTRODUCTION: Large prospective trials have demonstrated that finerenone could reduce the risk of cardiovascular death and progression of renal failure among patients with chronic kidney disease associated heart failure and/or type 2 diabetes mellitus (T2DM). The aim of this study was to explore the molecular mechanism of finerenone in the treatment of cardiorenal diseases through network pharmacology. METHODS: The STITH, SwissTargetPrediction, PharmMapper, DrugBank, and ChEMBL databases were used to screen the targets of finerenone. The disease-related targets were retrieved from the DisGeNET, GeneCards, CTD, OMIM, and MalaCards databases. The protein-protein interaction (PPI) network was conducted with STRING database and Cytoscape software. The clusterProfiler R package was used to perform Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis. The interactions of key targets and finerenone were analyzed by molecular docking in Autodock software. Diabetes mellitus was induced by intraperitoneal injection of streptozotocin. Histopathology of myocardial and renal tissues was observed by hematoxylin-eosin (HE) staining, and detection of protein expressions was conducted using Western blotting. RESULTS: A total of 111 potential cardiorenal targets of finerenone were identified. The main mechanisms of action may be associated with lipids and atherosclerosis, fluid shear stress and atherosclerosis, AGE-RAGE signaling pathway in diabetic complications, and diabetic cardiomyopathy. The hub targets demonstrated by the PPI network were CASP3, ALB, MMP9, EGFR, ANXA5, IGF1, SRC, TNFRSF1A, IL2, and PPARG, and the docking results suggested that finerenone could bind to these targets with high affinities. HE staining revealed the cardiorenal protection of finerenone on diabetic mice. In addition, the protein expressions of CASP3 and EGFR were increased while ALB was decreased in myocardial and renal tissues in diabetic mice compared with control mice, which were reversed by finerenone. CONCLUSION: This study suggested that finerenone exerts cardiorenal benefits through multiple targets and pathways.

Pharmacological Research Progress of Novel Antihypertensive Drugs.

Cardiovascular disease stands as the leading cause of death globally, with hypertension emerging as an independent risk factor for its development. The worldwide prevalence of hypertension hovers around 30%, encompassing a staggering 1.2 billion patients, and continues to escalate annually. Medication plays a pivotal role in managing hypertension, not only effectively regulating blood pressure (BP) but also substantially mitigating the occurrence of cardiovascular and cerebrovascular diseases. This review comprehensively outlines the categories, mechanisms, clinical applications, and drawbacks of conventional antihypertensive drugs. It delves into the five primary pharmacological classifications, namely ß-receptor blockers, calcium channel blockers (CCBs), angiotensin-converting enzyme inhibitors (ACEIs), angiotensin receptor blockers (ARBs), and diuretics. The emphasis is placed on elucidating the mechanisms, advantages, and research progress of novel antihypertensive drugs targeting emerging areas. These include mineralocorticoid receptor antagonists (MRAs), atrial natriuretic peptides (ANPs), neutral endopeptidase inhibitors (NEPIs), sodium-dependent glucose transporter 2 inhibitors (SGLT-2Is), glucagon-like peptide-1 receptor agonists (GLP-1RAs), endothelin receptor antagonists (ERAs), soluble guanylate cyclase (sGC) agonists, brain aminopeptidase A inhibitors (APAIs), and small interfering ribonucleic acids (siRNAs) targeting hepatic angiotensinogen. Compared to conventional antihypertensive drugs, these novel alternatives exhibit favorable antihypertensive effects with minimal adverse reactions. This review serves as a valuable reference for future research and the clinical application of antihypertensive drugs.

Insights into drug development with quantitative systems pharmacology: A prospective case study of uncovering hyperkalemia risk in diabetic nephropathy with virtual clinical trials.

The quantitative systems pharmacology (QSP) approach is widely applied to address various essential questions in drug discovery and development, such as identification of the mechanism of action of a therapeutic agent, patient stratification, and the mechanistic understanding of the progression of disease. In this review article, we show the current landscape of the application of QSP modeling using a survey of QSP publications over 10 years from 2013 to 2022. We also present a use case for the risk assessment of hyperkalemia in patients with diabetic nephropathy treated with mineralocorticoid receptor antagonists (MRAs, renin-angiotensin-aldosterone system inhibitors), as a prospective simulation of late clinical development. A QSP model for generating virtual patients with diabetic nephropathy was used to quantitatively assess that the nonsteroidal MRAs, finerenone and apararenone, have a lower risk of hyperkalemia than the steroidal MRA, eplerenone. Prospective simulation studies using a QSP model are useful to prioritize pharmaceutical candidates in clinical development and validate mechanism-based pharmacological concepts related to the risk-benefit, before conducting large-scale clinical trials.

Individualized Treatment Effect Prediction with Machine Learning - Salient Considerations.

BACKGROUND: Machine learning-based approaches that seek to accomplish individualized treatment effect prediction have gained traction; however, some salient challenges lack wider recognition. METHODS: We describe key methodologic considerations for individualized treatment effect prediction models using data from the Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist Trial for spironolactone in heart failure with preserved ejection fraction. The causal survival forest algorithm was used for model development. Calibration and discrimination were evaluated using a bootstrapping-based internal validation procedure. Observed benefits were described for predicted benefit quartiles and quartiles of a known effect modifier: ejection fraction. A negative control analysis with noncardiovascular death as the outcome was implemented to detect confounding. RESULTS: Among 3445 participants, 671 events occurred over a median of 3.3 years of follow-up. In internal validation, a higher average observed benefit was noted among patients in the highest quartile of predicted benefit. The median (interquartile range) of the observed restricted mean survival time difference at 3.3 years at the highest quartile of model-predicted benefit was 62 days (32 to 83) and was 47 days (26 to 67) at the lowest quartile of ejection fraction. Body-mass index had higher contribution to prediction of benefit relative to other included measures (33.7% vs. glomerular filtration rate [27.3%], ejection fraction [15.1%], and younger age [12.8%]) No benefit was observed for noncardiovascular death at higher model-predicted benefit quartiles, although benefit for noncardiovascular death was observed at lower quartiles. CONCLUSIONS: Carefully applied and validated predictive models hold promise in identifying heterogeneous treatment effects and are useful for hypothesis generation regarding the role of phenotypic characteristics in modifying the benefit of experimental interventions in clinical trials.

Mineralocorticoid Receptor Antagonists in Patients With Heart Failure and Impaired Renal Function.

BACKGROUND: Kidney dysfunction often leads to reluctance to start or continue life-saving heart failure (HF) therapy. OBJECTIVES: This study sought to examine the efficacy and safety of mineralocorticoid receptor antagonists (MRAs) in patients with HF with reduced ejection fraction experiencing significant kidney dysfunction. METHODS: We pooled individual patient data from the RALES (Randomized Aldactone Evaluation Study) and EMPHASIS-HF (Eplerenone in Mild Patients Hospitalization and Survival Study in Heart Failure) trials. The association between MRA treatment and outcomes was assessed according to whether the estimated glomerular filtration rate (eGFR) declined to <30 mL/min/1.73 m2 or not. The primary outcome was cardiovascular death or HF hospitalization. RESULTS: Among 4,355 patients included, 295 (6.8%) experienced a deterioration of eGFR after randomization to <30 mL/min/1.73 m2. These patients had more impaired baseline cardiac and kidney function (eGFR 47.3 ± 13.4 mL/min/1.73 m2 vs 70.5 ± 21.8 mL/min/1.73 m2) and had a higher risk of the primary outcome than patients without eGFR deterioration (HR: 2.49; 95% CI: 2.01-3.08; P < 0.001). However, the risk reduction in the primary outcome with MRA therapy was similar in those who experienced a decrease in eGFR to <30 mL/min/1.73 m2 (HR: 0.65; 95% CI: 0.43-0.99) compared with those who did not (HR: 0.63; 95% CI: 0.56-0.71) (Pinteraction = 0.87). In patients with a decrease in eGFR to <30 mL/min/1.73 m2, 21 fewer individuals (per 100 person-years) experienced the primary outcome with MRA treatment, vs placebo, compared with an excess of 3 more patients with severe hyperkalemia (>6.0 mmol/L). CONCLUSIONS: Because patients experiencing a decrease in eGFR to <30 mL/min/1.73 m2 are at very high risk, the absolute risk reduction with an MRA in these patients is large and this decline in eGFR should not automatically lead to treatment discontinuation.

A review regarding the article 'Mineralocorticoid receptor antagonists in heart failure with reduced ejection fraction: a network meta-analysis of 32 randomized trials'.

Heart failure (HF) is a prevalent clinical syndrome characterized by significant morbidity and is often precipitated by impaired left ventricular myocardial function. The condition can be categorized into two primary forms based on the ejection fraction (EF): Heart failure with preserved ejection fraction (HFpEF) and Heart failure with reduced ejection fraction (HFrEF). Evidence-based treatments for HF have been instrumental in reducing morbidity and mortality, particularly in patients with HFrEF. Mineralocorticoid receptor antagonists (MRAs) represent a cornerstone in the pharmacological management of HF, with a strong indication for use in HFrEF. Notably, pharmacological nuances exist among MRAs, which may influence therapeutic decision-making for individual patients. Moreover, MRAs have been shown to enhance heart rate variability and improve cardiac sympathetic nervous system function in HF patients. Spironolactone, an MRA, has been a pivotal agent in the clinical management of HFrEF since its introduction. However, its use has been tempered by certain side effects, including gynecomastia and hyperkalemia, leading to considerable discontinuation rates among patients. To address these challenges, numerous randomized clinical trials (RCTs) have been conducted to assess the efficacy and safety profiles of alternative steroidal and non-steroidal MRAs. Eplerenone, a steroidal MRA introduced subsequent to spironolactone, has demonstrated efficacy with a more favorable side effect profile.

The national financial burden of guideline directed medical therapy for heart failure patients from 2013 to 2021.

BACKGROUND: Guideline Directed Medical Therapy (GDMT) has been revolutionary in improving outcomes of heart failure patients. However, with the addition of more medication classes, the annual cost of these medications on the US healthcare system needs further evaluation. OBJECTIVES: We aim to evaluate the trend of annual cost of GDMT from 2013 to 2021 using the Medicare-part D Database. METHODS: Using Medicare Part D database (2013-2021), we determined the number of beneficiaries receiving these drugs, the total number of 30-day fills for each medication, and the total annual spending on these medications. Linear regression was used to analyze data using Python Programming Language. P value of less than 0.05 was considered to be statistically significant. RESULTS: The estimated annual Medicare- part D spending on empagliflozin had a 50 % increase in cost between 2020 and 2021, which could be attributed to its FDA approval for heart failure with reduced ejection fraction. Empagliflozin cost Medicare 3.73 billion USD in 2021 alone. In addition, sacubitril-valsartan had a strong trajectory since its introduction to the market in 2015. Since its approval in July 2015, it cost Medicare 4.51 billion USD. The Mineralocorticoid Receptor Antagonist class was the least costly class of GDMT. CONCLUSION: The rise in the cost of GDMT is not proportionate amongst the different classes of GDMT. Newer classes of medications cast a significant cost on Medicare in recent years.

Mineralocorticoid receptor antagonists in heart failure with reduced ejection fraction: a systematic review and network meta-analysis of 32 randomized trials.

INTRODUCTION: Several randomized controlled trials (RCTs) have examined mineralocorticoid receptor antagonists (MRAs) in heart failure (HF) with reduced ejection fraction (HFrEF). This systematic review and network meta-analysis (NMA) evaluated the comparative efficacy and safety of MRAs in HFrEF. MATERIALS AND METHODS: MEDLINE(Pubmed), Scopus, Cochrane and ClinicalTrials.gov were searched until April 8, 2024 for RCTs examining the efficacy and/or safety of MRAs in HFrEF. Double-independent study selection, extraction and quality assessment were performed. Random-effects frequentist NMA models were used. Evidence certainty was assessed via Grading of Recommendations Assessment, Development and Evaluation (GRADE). RESULTS: Totally, 32 RCTs (15685 patients) were analyzed. Eplerenone ranked above spironolactone in all-cause mortality (hazard ratio {HR}=0.78, 95% confidence interval {CI} [0.66,0.91], GRADE:"Moderate"), cardiovascular death (HR=0.74, 95%CI [0.53, 1.04], GRADE:"Low") and in all safety outcomes. Spironolactone was superior to eplerenone in the composite of cardiovascular death or hospitalization (HR=0.67, 95%CI [0.50,0.89], GRADE:"Moderate"), HF hospitalization (HR=0.61, 95%CI [0.43,0.86], GRADE:"Moderate"), all-cause hospitalization (HR=0.51, 95%CI [0.26,0.98], GRADE:"Moderate") and cardiovascular hospitalization (HR=0.56, 95%CI [0.37,0.84], GRADE:"Moderate"). Canrenone ranked first in all-cause mortality, the composite outcome and HF hospitalization. Finerenone ranked first in hyperkalemia (risk ratio [RR]=1.56, 95%CI [0.89,2.74], GRADE:"Moderate"), renal injury (RR=0.56, 95%CI [0.24,1.29]), any adverse event (RR=0.84, 95%CI [0.75,0.94], GRADE:"Moderate"), treatment discontinuation (RR=0.89, 95%CI [0.64,1.23]) and hypotension (RR=1.06, 95%CI [0.12,9.41]). CONCLUSIONS: MRAs are effective in HFrEF with certain safety disparities. Spironolactone and eplerenone exhibited similar efficacy, however, eplerenone demonstrated superior safety. Finerenone was the safest MRA, while canrenone exhibited considerable efficacy, nonetheless, evidence for these MRAs were scarce.

Renal effects and safety between Asian and non-Asian chronic kidney disease and type 2 diabetes treated with nonsteroidal mineralocorticoid antagonists.

BACKGROUND: Asians bear a heavier burden of chronic kidney disease (CKD), a common comorbidity of type 2 diabetes mellitus (T2DM), than non-Asians. Nonsteroidal mineralocorticoid receptor antagonists (MRAs) have garnered attention for their potential advantages in renal outcomes. Nevertheless, the impact on diverse ethnic groups remains unknown. METHODS: The PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang database, and clinical trial registries were searched through August 2023 with the following keywords: nonsteroidal MRAs (finerenone, apararenone, esaxerenone, AZD9977, KBP-5074), CKD, T2DM, and randomized controlled trial (RCT). A random effects model was used to calculate overall effect sizes. RESULTS: Seven RCTs with 14 997 participants were enrolled. Nonsteroidal MRAs reduced urinary albumin to creatinine ratio (UACR) significantly more in Asians than non-Asians: (weighted mean difference [WMD], -0.59, 95% CI, -0.73 to -0.45, p < .01) vs (WMD, -0.29, 95% CI, -0.32 to -0.27, p < .01), respectively. The average decline of estimated glomerular filtration rate (eGFR) was similar in Asians and non-Asians (p > .05). Regarding systolic blood pressure (SBP), nonsteroidal MRAs had a better antihypertension performance in Asians (WMD, -5.12, 95% CI, -5.84 to -4.41, p < .01) compared to non-Asians (WMD, -3.64, 95% CI, -4.38 to -2.89, p < .01). A higher incidence of hyperkalemia and eGFR decrease ≥30% was found in Asians than non-Asians (p < .01). CONCLUSIONS: Nonsteroidal MRAs exhibited significant renal benefits by decreasing UACR and lowering SBP in Asian than that of non-Asian patients with CKD and T2DM, without increase of adverse events except hyperkalemia and eGFR decrease ≥30%.
