Kill two birds with one stone:Hapatologist’s approach to metabolic dysfunction-associated steatotic liver disease and heart failure

Heart failure(HF)is a major global public health concern,and one of the less commonly known risk factors for HF development is metabolic dysfunction-associated steatotic liver disease(MASLD),as they share a similar pathophysio-logical background.In this article,we evaluated a recently published review article by Arriola-Montenegro et al.This article briefly summarizes the common pathophysiology of HF and MASLD development and evaluates the available therapeutic options to treat both conditions.Clinical practice guidelines highlight the importance of initiating and titrating guideline-directed medication therapy(GDMT)for patients with HF with reduced ejection fraction.GDMT is comprised of the four pillars currently proposed in most clinical practice guidelines,namely angiotensin-converting enzyme inhibitors(ACEIs),angiotensin receptor blockers(ARBs),angiotensin receptor-neprilysin inhibitors,beta-blockers,mineralocor-ticoid receptor antagonists,and sodium-glucose co-transporter 2 inhibitors(SGLT-2i).Given the similarity of pathophysiology and risk factors,recent studies for GDMT regarding ACEIs,ARBs,mineralocorticoid receptor antagonists,and SGLT-2i have shown beneficial effects on MASLD.Nonetheless,other medications for both conditions and novel therapies require more robust data and well-designed clinical studies to demonstrate their efficacies in both conditions.

BACKGROUND The specific benefits of Yangxinshi tablet(YXST)in the treating chronic heart failure(CHF)remain uncertain.AIM To systematically evaluate the efficacy and safety of YXST in the treatment of CHF.METHODS Randomized controlled trials(RCTs)investigating YXST for CHF treatment were retrieved from eight public databases up to November 2023.Meta-analyses of the included clinical studies were conducted using Review Manager 5.3.RESULTS Twenty RCTs and 1845 patients were included.The meta-analysis results showed that the YXST combination group,compared to the conventional drug group,significantly increased the clinical efficacy rate by 23%[relative risk(RR)=1.23,95%CI:1.17-1.29],(P<0.00001),left ventricular ejection fraction by 6.69%[mean difference(MD)=6.69,95%CI:4.42-8.95,P<0.00001]and 6-min walk test by 49.82 m(MD=49.82,95%C:38.84-60.80,P<0.00001),and reduced N-terminal pro-Btype natriuretic peptide by 1.03 ng/L[standardized MD(SMD)=-1.03,95%CI:-1.32 to-0.74,P<0.00001],brain natriuretic peptide by 80.95 ng/L(MD=-80.95,95%CI:-143.31 to-18.59,P=0.01),left ventricular end-diastolic diameter by 3.92 mm(MD=-3.92,95%CI:-5.06 to-2.78,P<0.00001),and left ventricular endsystolic diameter by 4.34 mm(MD=-4.34,95%CI:-6.22 to-2.47,P<0.00001).Regarding safety,neither group reported any serious adverse events during treatment(RR=0.54,95%CI:0.15-1.90,P=0.33).In addition,Egger's test results indicated no significant publication bias(P=0.557).CONCLUSION YXST effectively improves clinical symptoms and cardiac function in patients with CHF while maintaining a favorable safety profile,suggesting its potential as a therapeutic strategy for CHF.

Effect of dapagliflozin on uric acid in patients with chronic heart failure and hyperuricemia

BACKGROUND Patients with chronic heart failure(CHF)frequently develop hyperuricemia,an elevated serum uric acid level,associated with adverse outcomes.Dapagliflozin,a sodium-glucose cotransporter-2 inhibitor,demonstrates reduction in cardiovascular mortality and hospitalization in patients with CHF and ejection fraction(HFrEF),irrespective of diabetes.However,dapagliflozin’s effect on the uric acid levels in patients with CHF and hyperuricemia remain unclear.AIM To investigate the effects of dapagliflozin on uric acid levels in CHF patients with hyperuricemia.METHODS We conducted a randomized,double-blind,placebo-controlled trial in 200 patients with CHF and hyperuricemia,with HFrEF and serum uric acid levels≥7 mg/dL(≥416μmol/L).The participants were randomly assigned to receive a daily dose of 10 mg dapagliflozin or placebo for 24 months.The primary endpoint was the change in serum uric acid level from baseline to 24 months.Secondary endpoints included changes in left ventricular ejection fraction(LVEF),Nterminal pro-B-type natriuretic peptide(NT-proBNP),and quality of life(QoL)scores,as well as the incidence of cardiovascular death and hospitalization for heart failure.RESULTS At 24 months,dapagliflozin significantly reduced serum uric acid levels by 1.2 mg/dL(71μmol/L)compared with placebo(95%CI:-1.5 to-0.9;P<0.001).Dapagliflozin also significantly improved LVEF by 3.5%(95%CI:2.1-4.9;P<0.001),NT-proBNP by 25%(95%CI:18-32;P<0.001),and QoL scores by 10 points(95%CI:7-13;P<0.001)and reduced the risk of cardiovascular death and hospitalization for heart failure by 35%(95%CI:15–50;P=0.002)compared with the placebo.Adverse events were similar between the two groups,except for a higher rate of genital infections in the dapagliflozin group(10%vs 2%,P=0.01).CONCLUSION Dapagliflozin significantly lowered serum uric acid levels and improved the clinical outcomes in patients with CHF and hyperuricemia.Therefore,dapagliflozin may be a useful therapeutic option for this high-risk population.

Assessing myocardial indices and inflammatory factors to determine anxiety and depression severity in patients with chronic heart failure

BACKGROUND Patients with chronic heart failure(CHF)have a progressive disease that is associated with poor quality of life and high mortality.Many patients experience anxiety and depression(A&D)symptoms,which can further accelerate disease progression.We hypothesized that indicators of myocardial function and inflammatory stress may reflect the severity of A&D symptoms in patients with CHF.Changes in these biomarkers could potentially predict whether A&D symptoms will deteriorate further in these individuals.AIM To measure changes in cardiac and inflammatory markers in patients with CHF to determine A&D severity and predict outcomes.METHODS We retrospectively analyzed 233 patients with CHF treated at the Jingzhou Hospital,Yangtze University between 2018-2022 and grouped them according to Self-Rating Anxiety Scale(SAS)and Self-Rating Depression Scale(SDS)scores.We compared clinical data in the no-A&D,mild-A&D,moderate-A&D,and severe-A&D groups,the SAS and SDS scores with the New York Heart Association(NYHA)functional classification,and cardiac markers and inflammatory factors between the no/mild-A&D and moderate/severe-A&D groups.Regression analysis was performed on the markers with P<0.05 to determine their ability to predict A&D severity in patients and the area under the receiver operating characteristic curve(AUROC)was used to evaluate their accuracy.RESULTS In the inter-group comparison,the following variables had an effect on A&D severity in patients with CHF:NYHA class,left ventricular ejection fraction(LVEF),left ventricular end-diastolic diameter,N-terminal pro-brain natriuretic peptide(NT-proBNP),interleukin-6(IL-6),and tumor necrosis factor-alpha(P<0.05).Other variables did not differ significantly between the A&D groups(P>0.05).In addition,we found that higher NYHA classes were associated with higher the SAS and SDS scores(P<0.05).Regression analysis showed that LVEF,NTproBNP,and IL-6 were independent risk factors for A&D severity(P<0.05).Among them,NT-proBNP had the best predictive ability as a single indicator(AUROC=0.781).Furthermore,the combination of these three indicators exhibited a good predictive effect toward discriminating the extent of A&D severity among patients(AUROC=0.875).CONCLUSION Cardiac and inflammatory biomarkers,such as LVEF,NT-proBNP,and IL-6,are correlated with A&D severity in patients with CHF and have predictive value.

Correlation among anxiety and depression,fear of disease progression,and social support in coronary heart disease

BACKGROUND The mental well-being of individuals with coronary heart disease(CHD)during the intensive care unit(ICU)transition period is a multifaceted and significant concern.In this phase,the individuals might encounter psychological challenges like anxiety and depression,which can impede their recuperation and potentially have lasting effects on their health.AIM To investigate the correlation among psychological factors in CHD patients in the ICU transition period.METHODS A questionnaire survey was conducted with 119 patients admitted to the ICU after coronary artery bypass grafting between March and December 2023.Variations in Hamilton Anxiety Scale(HAMA)and Hamilton Depression Scale(HAMD),Fear of Progression Questionnaire-Short Form(Fop-Q-SF),and Social Support Rating Scale(SSRS)were collected and analyzed among diverse populations.We used Pearson’s correlation analysis to examine the correlation.Multiple linear regression analysis was used to explore whether these indicators influenced depression and anxiety in the patients.RESULTS The total scores for anxiety,depression,fear of disease progression,and social support were(7.50±1.41)points,(8.38±1.62)points,(35.19±8.14)points,and(36.34±7.08)points,respectively(P<0.05).Multivariate regression analysis showed that both the level of disease progression and social support affected the level of postoperative depression and anxiety in patients.CONCLUSION The anxiety and depression levels were positively related to each dimension of phobia disease progression and negatively related to each dimension of social support among patients with CHD.

Sodium-dependent glucose transporter 2 inhibitors effects on myocardial function in patients with type 2 diabetes and asymptomatic heart failure

BACKGROUND Sodium-dependent glucose transporter 2 inhibitors(SGLT2i)have shown efficacy in reducing heart failure(HF)burden in a very heterogeneous groups of patients,raising doubts about some contemporary assumptions of their mechanism of action.We previously published a prospective observational study that evaluated mechanisms of action of SGLT2i in patients with type 2 diabetes who were in HF stages A and B on dual hypoglycemic therapy.Two groups of patients were included in the study:the ones receiving SGLT2i as an add-on agent to metformin and the others on dipeptidyl peptidase-4 inhibitors as an add-on to metformin due to suboptimal glycemic control.AIM To evaluate the outcomes regarding natriuretic peptide,oxidative stress,inflammation,blood pressure,heart rate,cardiac function,and body weight.METHODS The study outcomes were examined by dividing each treatment arm into two subgroups according to baseline parameters of global longitudinal strain(GLS),N-terminal pro-brain natriuretic peptide,myeloperoxidase(MPO),high-sensitivity C-reactive protein(hsCRP),and systolic and diastolic blood pressure.To evaluate the possible predictors of observed changes in the SGLT2i arm during follow-up,a rise in stroke volume index,body mass index(BMI)decrease,and lack of heart rate increase,linear regression analysis was performed.RESULTS There was a greater reduction of MPO,hsCRP,GLS,and blood pressure in the groups with higher baseline values of mentioned parameters irrespective of the therapeutic arm after 6 months of follow-up.Significant independent predictors of heart rate decrease were a reduction in early mitral inflow velocity to early diastolic mitral annular velocity at the interventricular septal annulus ratio and BMI,while the predictor of stroke volume index increase was SGLT2i therapy itself.CONCLUSION SGLT2i affect body composition,reduce cardiac load,improve diastolic/systolic function,and attenuate the sympathetic response.Glycemic control contributes to the improvement of heart function,blood pressure control,oxidative stress,and reduction in inflammation.
