Therapies for patients with coexisting heart failure with reduced ejection fraction and non-alcoholic fatty liver disease

Heart failure with reduced ejection fraction(HFrEF)and nonalcoholic fatty liver disease(NAFLD)are two common comorbidities that share similar pathophysiological mechanisms.There is a growing interest in the potential of targeted therapies to improve outcomes in patients with coexisting HFrEF and NAFLD.This manuscript reviews current and potential therapies for patients with coexisting HFrEF and NAFLD.Pharmacological therapies,including angiotensinconverting enzyme inhibitors/angiotensin receptor blockers,mineralocorticoids receptor antagonist,and sodium-glucose cotransporter-2 inhibitors,have been shown to reduce fibrosis and fat deposits in the liver.However,there are currently no data showing the beneficial effects of sacubitril/valsartan,ivabradine,hydralazine,isosorbide nitrates,digoxin,or beta blockers on NAFLD in patients with HFrEF.This study highlights the importance of considering HFrEF and NAFLD when developing treatment plans for patients with these comorbidities.Further research is needed in patients with coexisting HFrEF and NAFLD,with an emphasis on novel therapies and the importance of a multidisciplinary approach for managing these complex comorbidities.

One Case of Diabetes Nephropathy Stage V, Combined Valvular Disease, Total Heart Failure with Diabetes Foot Gangrene

The patient was found to have 4+urine sugar by physical examination 14 years ago and was treated with oral hypoglycemic drugs. Insulin was injected intramuscularly nine years ago. Two and a half years ago, it was found that the color of the thumb, index and middle toe of the left foot became black. He went to a third-class hospital in Beijing and was diagnosed as “diabetes foot”. He was treated with “balloon dilation of lower limb blood vessels of diabetes foot”. Half a year ago, the third toe on the right side was broken and treated in the hospital again. “Popliteal artery stent implantation” was given for the diagnosis of “double kidney insufficiency, diabetes foot, left heart failure, combined heart valve disease”, “Hemofiltration therapy” and anti-inflammatory, amino acid supplementation, kidney function protection, anticoagulation, anemia correction and other treatments. Later, he went to our hospital and was diagnosed by the TCM diagnosis: category of consumptive disease, toe or finger gangrene (syndrome/pattern of qi and yin deficiency). Western medicine diagnosed: stage V of diabetes nephropathy, type II diabetes foot gangrene, combined with heart valve disease, hypoalbuminemia, double kidney cyst, moderate anemia, pleural effusion, hyperkalemia, pulmonary infection, and total heart failure. The patient was treated by the Qi-acupuncture therapy of TCM in combination with Chinese and Western medicine Medical treatment made the patient significantly better and discharged.

Heart failure and chronic obstructive pulmonary disease: Two for tea or tea for two?

A combination of chronic obstructive pulmonary disease (COPD) and heart failure (HF) is common yet it is inadequately and rarely recognized. Because of the similar clinical manifestations, comorbidity is frequently not considered and appropriate diagnostic tests are not performed. It is very important that a combination of COPD and HF is recognized as these patients have a worse prognosis than patients with an individual disease. When present, COPD should not prevent the use of life-saving therapy in patients with HF, particularly β-blockers. Despite clear evidence of the safety and tolerability of cardioselective β-blockers in COPD patients, these drugs remain grossly underprescribed and underdosed. Routine spirometry and echocardiography in HF and COPD patients, respectively, is therefore warranted to improve current clinical practice.

Moving forward on the pathway of cell-based therapies in ischemic heart disease and heart failure-time for new recommendations?

Although substantial advances have been made in treating ischemic heart disease and subsequent heart failure, the overall morbidity and mortality from these conditions remain high. Stem cell-based therapy has emerged as a promising approach for prompting cardiac rejuvenation. Various cell types have been tested in the clinical arena, proving consistent safety results. As for efficiency outcomes, contradictory findings have been reported, partly due to inconsistency in study protocols but also due to poor survival, engraftment and differentiation of transplanted cells in the hostile milieu of the ischemic host tissue. Studies have varied in terms of route of delivery, type and dose of implanted stem cells, patient selection and randomization, and assessment of therapeutic effect. Founded on the main achievements and challenges within almost 20 years of research, a number of official documents have been published by leading experts in the field. Core recommendations have focused on developing and optimizing effective strategies to enrich cell retention and their regenerative potential. Issued consensus and position papers have stemmed from an unmet need to provide a harmonized framework for future research, resulting in improved therapeutic application of cell-based therapies for cardiac regeneration and repair.

Short-term outcomes in heart failure patients with chronic obstructive pulmonary disease in the community

AIM:To establish the short term outcomes of heart failure(HF)patients in the community who have concurrent chronic obstructive pulmonary disease(COPD).METHODS:We evaluated 783 patients(27.2%)with left ventricular systolic dysfunction under the care of a regional nurse-led community HF team between June 2007 and June 2010 through a database analysis.RESULTS:One hundred and one patients(12.9%)also had a diagnosis of COPD;94% of patients were treated with loop diuretics,83% with angiotensin converting enzyme inhibitors,74% with β-blockers;10.6% with bronchodilators;and 42% with aldosterone an-tagonists.The mean age of the patients was 77.9 ± 5.7 years;43% were female and mean New York Heart Association class was 2.3 ± 0.6.The mean follow-up was 28.2 ± 2.9 mo.β-blocker utilization was markedly lower in patients receiving bronchodilators compared with those not taking bronchodilators(overall 21.7% vs 81%,P < 0.001).The 24-mo survival was 93% in patients with HF alone and 89% in those with both comorbidities(P = not significant).The presence of COPD was associated with increased risk of HF hospitalization [hazard ratio(HR):1.56;95% CI:1.4-2.1;P < 0.001] and major adverse cardiovascular events(HR:1.23;95% CI:1.03-1.75;P < 0.001).CONCLUSION:COPD is a common comorbidity in ambulatory HF patients in the community and is a powerful predictor of worsening HF.It does not however appear to affect short-term mortality in ambulatory HF patients.

Effect of ivabradine in the treatment of acute exacerbation of chronic obstructive pulmonary disease with heart failure

Objective: To observe the effectiveness and safety of ivabradine in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) and heart failure. Methods:Patients who were admitted to hospital with AECOPD during the period from August 2017 to July 2018. Then those both had heart failure with reduced ejection fraction(HFrEF) and a resting heart rate>70 beats/min were enrolled. A total of 86 cases were screened and completed, which were randomly divided into two groups for treatment. The control group(41 cases) received standard treatments, such as oxygen, anti-infection, anti-spasmodic, hormone, diuretic, ACEI/ARB, recombinant human brain natriuretic peptide (rhBNP), etc. The bisoprolol was given 2.5~5 mg orally once a day to control heart rate, and the test group(45 cases) was further treated with ivabradine 2.5~5 mg orally twice a day on the basis of the control group. The average heart rate, cardiac function, lung function, and 6-minute walking test were compared between the two groups. Results: After treatment, the average heart rate of the test group was lower than the control group, and the heart rate control rate(<70 beats/min%) of the test group was superior to the control group. The level of N-terminal B-type natriuretic peptide(NT-proBNP) in test group was significantly lower than that in control group. The distance of the 6-minute walking test in e test group was significantly longer than that in control group. Conclusion: Ivabradine combined with bisoprolol could help patients with AECOPD and heart failure to further reduce the heart rates, improve heart function and exercise tolerance. Moreover, the therapeutic safety was acceptable during the short term.

Effect of sequential assist-control ventilation on cardio-pulmonary function and systemic inflammatory state of chronic pulmonary heart disease complicated with respiratory failure patients

Objective:To discuss the effect of sequential assist-control ventilation on cardio-pulmonary function and systemic inflammatory state of chronic pulmonary heart disease complicated with respiratory failure patients.Method: A total of 90 cases of chronic pulmonary heart disease complicated with respiratory failure patients, who were treated in our hospital between May, 2012 and Feb., 2016, were selected, and were divided into study group (n=45) and control group (n=45) based on random number table. Patients in control group were given auxiliary - control ventilation. (A/C) treatment during the whole course, while patients in study group were given A/C+BiPAP treatment. Cardio-pulmonary function and serum inflammatory factor content difference was compared inboth groups before and after operation.Results: Before treatment, difference ofcardiac function indicator, ABG level and inflammatory factor content in both groups had no statistical significance. After treatment, cardiac function indicator (PASP, RVd) levels in both groups were lower than before treatment, and EFRV levels were higher than before treatment, and changes in study group were more obvious than that in control group;ABG indicator (PaO2) levels in both groups were higher than before treatment, and PaCO2 levels werelower than before treatment, and changes in study group were more obvious than that in control group;serum inflammatory factor (hs-CRP, IL-6, TNF-α) content in both groups was lower than before treatment, and changes in study group were more obvious than that in control group.Conclusion: sequential assist-control ventilation could optimize the cardio-pulmonary function of chronic pulmonary heart disease complicated with respiratory failure patients and reduce the systemic inflammatory response.

Heart failure as an adverse effect of infliximab for Crohn's disease: A case report and review of the literature

BACKGROUND Anti-tumor necrosis factor agents were the first biologic therapy approved for the management of Crohn's disease(CD).Heart failure(HF)is a rare but potential adverse effect of these medications.The objective of this report is to describe a patient with CD who developed HF after the use of infliximab.CASE SUMMARY A 50-year-old woman with a history of hypertension and diabetes presented with abdominal pain,diarrhea,and weight loss.Colonoscopy and enterotomography showed ulcerations,areas of stenosis and dilation in the terminal ileum,and thickening of the intestinal wall.The patient underwent ileocolectomy and the surgical specimen confirmed the diagnosis of stenosing CD.The patient started infliximab and azathioprine treatment to prevent post-surgical recurrence.At 6 mo after initiating infliximab therapy,the patient complained of dyspnea,orthopnea,and paroxysmal nocturnal dyspnea that gradually worsened.Echocardiography revealed biventricular dysfunction,moderate cardiac insufficiency,an ejection fraction of 36%,and moderate pericardial effusion,consistent with HF.The cardiac disease was considered an infliximab adverse effect and the drug was discontinued.The patient received treatment with diuretics for HF and showed improvement of symptoms and cardiac function.Currently,the patient is using anti-interleukin for CD and is asymptomatic.CONCLUSION This reported case supports the need to investigate risk factors for HF in inflammatory bowel disease patients and to consider the risk-benefit of introducing infliximab therapy in such patients presenting with HF risk factors.

Animal models of pulmonary hypertension due to left heart disease

Pulmonary hypertension due to left heart disease(PH-LHD) is regarded as the most prevalent form of pulmonary hypertension(PH). Indeed, PH is an independent risk factor and predicts adverse prognosis for patients with left heart disease(LHD). Clinically, there are no drugs or treatments that directly address PH-LHD, and treatment of LHD alone will not also ameliorate PH. To target the underlying physiopathological alterations of PH-LHD and to develop novel therapeutic approaches for this population, animal models that simulate the pathophysiology of PH-LHD are required. There are several available models for PH-LHD that have been successfully employed in rodents or large animals by artificially provoking an elevated pressure load on the left heart, which by transduction elicits an escalated pressure in pulmonary artery. In addition, metabolic derangement combined with aortic banding or vascular endothelial growth factor receptor antagonist is also currently applied to reproduce the phenotype of PH-LHD. As of today, none of the animal models exactly recapitulates the condition of patients with PH-LHD. Nevertheless, the selection of an appropriate animal model is essential in basic and translational studies of PH-LHD. Therefore, this review will summarize the characteristics of each PH-LHD animal model and discuss the advantages and limitations of the different models.

Effectiveness of chest radiography,lung ultrasound and thoracic computed tomography in the diagnosis of congestive heart failure

Hydrostatic pulmonary edema is as an abnormal in-crease in extravascular water secondary to elevatedpressure in the pulmonary circulation, due to conges-tive heart failure or intravascular volume overload.Diagnosis of hydrostatic pulmonary edema is usuallybased on clinical signs associated to conventional ra-diography findings. Interpretation of radiologic signsof cardiogenic pulmonary edema are often question-able and subject. For a bedside prompt evaluation,lung ultrasound(LUS) may assess pulmonary conges-tion through the evaluation of vertical reverberationartifacts, known as B-lines. These artifacts are relatedto multiple minimal acoustic interfaces between smallwater-rich structures and alveolar air, as it happens incase of thickened interlobular septa due to increase of extravascular lung water. The number, diffusion and in-tensity of B lines correlates with both the radiologic andinvasive estimate of extravascular lung water. The inte-gration of conventional chest radiograph with LUS canbe very helpful to obtain the correct diagnosis. Com-puted tomography(CT) is of limited use in the work upof cardiogenic pulmonary edema, due to its high cost,little use in the emergencies and radiation exposure.However, a deep knowledge of CT signs of pulmonaryedema is crucial when other similar pulmonary condi-tions may occasionally be in the differential diagnosis.

Multi-Institutional US Experience of the Occlutech AFR Device in Congenital and Acquired Heart Disease

Objectives:To detail the US multi-institutional experience with the Occlutech©(Occlutech International AB,Helsingborg,Sweden)atrial flow regulator(AFR)in children and adults with acquired or congenital heart disease.Background:The creation of a long-term atrial communication is desirable in several cardiovascular disease phenotypes,most notably pulmonary arterial hypertension,disorders of increased left ventricular filling and increased cavopulmonary pressures in patients with a Fontan type circulation.Methods:Patients were identified for inclusion from the AFR device manufacturer database.Data was collected using a RedCap database following IRB approval.8 weeks of follow up data was sought for each patient based on available data.Data was analyzed and summarized using SPSS.Results:We report the experience of 6 US centers in the implantation of AFR devices in 15 patients,across a wide age range,with different disease phenotypes and a variety of indications.Implantation was technically successful in all patients and improvement was noted in both clinical and hemodynamic parameters.There were no immediate or intermediate term complications reported.3 patients died remote from implantation.Their deaths were not felt to be related to the AFR device or related procedural complications.Conclusion:Compassionate use of the AFR device in children and adults with congenital&acquired heart disease is technically feasible and produces beneficial short term hemodynamic and symptomatic improvement.Widespread uptake of this technique and treatment at specialist centers has the potential to provide significant benefits to a variety of complex patients with currently limited treatment options and indeterminate prognosis.

Correlation analysis between lung ultrasound scores and pulmonary arterial systolic pressure in patients with acute heart failure admitted to the emergency intensive care unit

Background:No convenient,inexpensive,and non-invasive screening tools exist to identify pulmonary hypertension(PH)-left heart disease(LHD)patients during the early stages of the disease course.This study investigated whether different methods of lung ultrasound(LUS)could be used for the initial investigation of PH-LHD.Methods:This was a single-center prospective observational study which was performed in the Zigong Fourth People’s Hospital.We consecutively enrolled patients with heart failure(HF)admitted to the emergency intensive care unit from January 2018 to May 2020.Transthoracic echocardiography and LUS were performed within 24 h before discharge.We used the Spearman coefficient for correlation analysis between ultrasound scores and pulmonary arterial systolic pressure(PASP).Bland-Altman plots were generated to inspect possible bias,and receiver operating characteristic(ROC)curves were calculated to assess the relationship between ultrasound scores and an intermediate and high echocardiographic probability of PH-LHD.Results:Seventy-one patients were enrolled in this study,with an overall median age of 79(interquartile range:71.5–84.0)years.Among the 71 patients,36(50.7%)cases were male,and 26(36.6%)had an intermediate and high echocardiographic probability of PH.All four LUS scores in patients with an intermediate and high probability of PH were significantly higher than in patients with a low probability of PH(P<0.05).The correlation coefficient(r)between different LUS scoring methods and PASP was moderate for the 6-zone(r=0.455,P<0.001),8-zone(r=0.385,P=0.001),12-zone(r=0.587,P<0.001),and 28-zone(r=0.535,P<0.001)methods.In Bland-Altman plots,each of the four LUS scoring methods had a good agreement with PASP(P<0.001).The 8-zone and 12-zone methods showed moderately accurate discriminative values in differentiating patients with an intermediate and high echocardiographic probability of PH(P<0.05).

Effect of dyspnea and clinical variables on the quality of life and functional capacity in patients with chronic obstructive pulmonary disease and congestive heart failure

Background Chronic obstructive pulmonary disease （COPD） and congestive heart failure （CHF） are two chronic diseases that affect negatively the functional condition and quality of life of patients. We assessed the effect of symptoms and clinical variables on the functional capacity and quality of life in COPD and CHF patients. Methods The study included 42 COPD and 39 CHF patients. In both patient groups, dyspnea was assessed using Borg scale; functional capacity by shuttle-walk and cardiopulmonary exercise test and quality of life by short form-36 （SF36）. Results No statistically significant difference was found in neither of the two disease groups regarding the dyspnea score, shuttle-walk test and the majority of subgroup scores of SF36 （P〉0.05）. A statistically significant difference was observed in peak VO2 in favor of COPD group （P〈0.05）. No significant relationship was established between dyspnea score and forced expiratory volume in one second （FEV1） in COPD patients, and left ventricular ejection fraction （LVEF） in CHF patients （P〉0.05）. A significant negative correlation was observed between dyspnea score and functional capacity tests in both disease groups （P〈0.05）. On the other hand, no relationship was found between LVEF and FEV1 and quality of life and functional capacity （P〉0.05）. Conclusions It was revealed that symptoms have an impact on functional capacity and quality of life in both disease groups, however, objective indicators of disease severity do not show a similar relationship. Therefore, in addition to the objective data related to the disease, we recommend that symptoms should also be taken into consideration to assess cardiopulmonary rehabilitation program and during following-up.

Prevalence, risk factors, and survival associated with pulmonary hypertension and heart failure among patients with underlying coronary artery disease: a national prospective, multicenter registry study in China

Background: Coronary artery disease (CAD) is the commonest cause of heart failure (HF), whereas pulmonary hypertension (PH) has not been established or reported in this patient population. Therefore, we assessed the prevalence, risk factors, and survival in CAD-associated HF (CAD-HF) complicated with PH.Methods: Symptomatic CAD-HF patients were continuously enrolled in this prospective, multicenter registry study. Echocardiography, coronary arteriography, left and right heart catheterization (RHC), and other baseline clinical data were recorded. Patients were followed up and their survival was recorded.Results: One hundred and eighty-two CAD-HF patients were enrolled, including 142 with HF with a preserved ejection fraction (heart failure with preserved ejection fraction [HFpEF];left ventricular ejection fraction [LVEF] ≥50%) and 40 with a reduced ejection fraction (heart failure with reduced ejection fraction [HFrEF];LVEF < 50%). PH was diagnosed with RHC in 77.5% of patients. Patients with PH showed worse hemodynamic parameters and higher mortality. HFrEF-PH patients had worse survival than HFpEF-PH patients. CAD-HF patients with an enlarged left ventricular end-diastolic diameter and reduced hemoglobin were at higher risk of PH. Nitrate treatment reduced the risk of PH. Elevated creatinine and mean pulmonary arterial pressure (mPAP), diastolic pressure gradient (DPG) ≥7 mmHg, and previous myocardial infarction (MI) entailed a higher risk of mortality in CAD-HF patients with PH.Conclusions: PH is common in CAD-HF and worsens the hemodynamics and survival in these patients. Left ventricle enlargement and anemia increase the risk of PH in CAD-HF. Patients may benefit from nitrate medications. Renal impairment, elevated mPAP, DPG ≥7 mmHg, and previous MI are strong predictors of mortality in CAD-HF-PH patients.Trial Registration: ClinicalTrials.gov, NCT02164526.

Testosterone and cardiovascular disease in men

Despite regional variations in the prevalence of coronary artery disease （CAD）, men are consistently more at risk of developing and dying from CAD than women, and the gender-specific effects of sex hormones are implicated in this inequality. This ＇Perspectives＇ article reviews the current evidence regarding the cardiovascular effects of testosterone in men including an examination of the age-related decline in testosterone, the relationship between testosterone levels and coronary disease, coronary risk factors and mortality. We also review the vaso-active effects of testosterone, and discuss how these have been used in men with heart failure and angina. We discuss the ＇cause＇ versus ＇effect＇ controversy, regarding low testosterone levels in men with coronary heart disease, as well as concerns over the use of testosterone replacement therapy in middle aged and elderly men. The article concludes with a discussion regarding the future direction for work in this interesting area, including the relative merits of screening for, and treating hypogonadism with testosterone replacement therapy in men with heart disease.

Andropause and the development of cardiovascular disease presentationmore than an epi-phenomenon

Andropause refers to a generalized decline of male hormones, including testosterone and dehydroepiandrosterone in middle-aged and aging men. This decline in hormones has been associated with changes such as depression, loss of libido, sexual dysfunction, and changes in body composition. Aging has been associated with an abundance of concomitant diseases, in particular cardiovascular diseases, and although andropause is correlated to aging, a causal relationship between reduction of androgens and the development of chronic diseases such as atherosclerosis and heart failure has not been convincingly established yet. On the other hand, increasing data has emerged that revealed the effects of low levels of androgens on cardiovascular disease progression. As an example, low levels of testosterone have been linked to a higher incidence of coronary artery disease. Whether hormone replacement therapy that is used for andropausal men to alleviate symptoms of ＂male menopause＂ can halt progression of cardiovascular disease, remains controversially discussed, primarily due to the lack of well-designed, randomized controlled trials. At least for symptom improvement, the use of androgen replacement therapy in andropausal men may be clinically indicated, and with the appropriate supervision and follow up may prove to be beneficial with regard to preservation of the integrity of cardiovascular health at higher ages.
