Abstract
Heart failure (HF) represents a major global health and economic burden with still unacceptably high morbidity and mortality rates. In recent decades, novel therapeutic opportunities with a significant impact on HF outcomes have been introduced in addition to angiotensin-converting enzyme (ACE) inhibitors, β-blockers, and mineralocorticoid receptor antagonists. These include drugs such as ivabradine, sacubitril-valsartan, and sodium-glucose cotransporter-2 (SGLT-2) inhibitors. The availability of an extremely large pharmacological armamentarium to face this chronic global disease highlights the importance of assessing cost effectiveness to promote sustainable healthcare. In light of the recent approval of SGLT-2 inhibitors for the treatment of HF with reduced ejection fraction, including in individuals without type 2 diabetes mellitus, the aim of this review was to provide an updated comparative evaluation of the efficacy and cost effectiveness of different pharmacological treatments for the prevention (stage A) and treatment of asymptomatic (stage B) and symptomatic (stages C-D) left ventricular dysfunction.

Abstract
BACKGROUND Women providers have a more patient-centered communication style than men, and some studies have found women primary care providers are more likely to meet quality performance measures. OBJECTIVE To explore gender differences in the quality of primary care process and outcome measures. DESIGN Retrospective analysis of primary care performance data from 1 year (2018-2019). PARTICIPANTS A total of 586 primary care providers (311 women and 275 men) who cared for 241,428 primary care patients at 96 primary care clinics at 8 Veterans Affairs (VA) medical centers. MAIN MEASURES Our primary outcome was a composite quality measure that averaged all thirty-four primary care performance measures that assessed performance in cancer screening, diabetes care, cardiovascular care, tobacco counseling, risky alcohol screening, immunizations, HIV testing, opiate care, and continuity. Our secondary outcomes were performance on each of the 34 measures. KEY RESULTS There was no difference in the average performance on our composite measure between men and women (75.8% vs. 76.6%, p = 0.17). Among the 34 primary care quality measures collected, there was no difference between male and female providers' performance. Using a more conservative cut-point, women were more likely to screen at-risk diabetic patients for hypoglycemia and document follow-up on risky alcohol behavior noted during patient check-in. These differences were clinically small and likely due to chance, given the multiple measures evaluated in this study. CONCLUSIONS We found little evidence of difference in the performance on primary care quality measures between male and female providers.

Abstract
BACKGROUND Anthracyclines are frequently used chemotherapeutic agents for childhood cancer that can cause cardiotoxicity during and after treatment. Although several medical interventions in adults with symptomatic or asymptomatic cardiac dysfunction due to other causes are beneficial, it is not known if the same treatments are effective for childhood cancer patients and survivors with anthracycline-induced cardiotoxicity. This review is an update of a previously published Cochrane review. OBJECTIVES To compare the effect of medical interventions on anthracycline-induced cardiotoxicity in childhood cancer patients or survivors with the effect of placebo, other medical interventions, or no treatment. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library, 2015, Issue 8), MEDLINE/PubMed (1949 to September 2015), and EMBASE/Ovid (1980 to September 2015) for potentially relevant articles. In addition, we searched reference lists of relevant articles, conference proceedings of the International Society for Paediatric Oncology (SIOP), the American Society of Clinical Oncology (ASCO), the American Society of Hematology (ASH), the International Conference on Long-Term Complications of Treatment of Children & Adolescents for Cancer, and the European Symposium on Late Complications from Childhood Cancer (from 2005 to 2015), and ongoing trial databases (the ISRCTN Register, the National Institutes of Health (NIH) Register, and the trials register of the World Health Organization (WHO); all searched in September 2015). SELECTION CRITERIA Randomised controlled trials (RCTs) or controlled clinical trials (CCTs) comparing the effectiveness of medical interventions to treat anthracycline-induced cardiotoxicity with either placebo, other medical interventions, or no treatment. DATA COLLECTION AND ANALYSIS Two review authors independently performed the study selection. One review author performed the data extraction and 'Risk of bias' assessments, which another review author checked. We performed analyses according to the guidelines in the Cochrane Handbook for Systematic Reviews of Interventions. MAIN RESULTS In the original version of the review we identified two RCTs; in this update we identified no additional studies. One trial (135 participants) compared enalapril with placebo in childhood cancer survivors with asymptomatic anthracycline-induced cardiac dysfunction. The other trial (68 participants) compared a two-week treatment of phosphocreatine with a control treatment (vitamin C, adenosine triphosphate, vitamin E, oral coenzyme Q10) in leukaemia patients with anthracycline-induced cardiotoxicity. Both studies had methodological limitations.The RCT on enalapril showed no statistically significant differences in overall survival, mortality due to heart failure, development of clinical heart failure, and quality of life between treatment and control groups. A post-hoc analysis showed a decrease (that is improvement) in one measure of cardiac function (left ventricular end-systolic wall stress (LVESWS): -8.62% change) compared with placebo (+1.66% change) in the first year of treatment (P = 0.036), but not afterwards. Participants treated with enalapril had a higher risk of dizziness or hypotension (risk ratio 7.17, 95% confidence interval 1.71 to 30.17) and fatigue (Fisher's exact test, P = 0.013).The RCT on phosphocreatine found no differences in overall survival, mortality due to heart failure, echocardiographic cardiac function, and adverse events between treatment and control groups. AUTHORS' CONCLUSIONS Only one trial evaluated the effect of enalapril in childhood cancer survivors with asymptomatic cardiac dysfunction. Although there is some evidence that enalapril temporarily improves one parameter of cardiac function (LVESWS), it is unclear whether it improves clinical outcomes. Enalapril was associated with a higher risk of dizziness or hypotension and fatigue. Clinicians should weigh the possible benefits with the known side effects of enalapril in childhood cancer survivors with asymptomatic anthracycline-induced cardiotoxicity.Only one trial evaluated the effect of phosphocreatine in childhood cancer patients with anthracycline-induced cardiotoxicity. Limited data with a high risk of bias showed no significant difference between phosphocreatine and control treatments on echocardiographic function and clinical outcomes.We did not identify any RCTs or CCTs studying other medical interventions for symptomatic or asymptomatic cardiotoxicity in childhood cancer patients or survivors.High-quality studies should be performed.

Abstract
Congestive heart failure (CHF) therapeutics is generated through a well-described evidence generating process. Phases 1 - 3 of this process are required prior to approval and widespread clinical use. Phase 3 in almost all cases is a methodologically sound randomized controlled trial (RCT). After this phase it is generally accepted that the treatment has a significant, independent and prognostically beneficial effect on the pathophysiological process. A major criticism of RCTs is the population to whom the result is applicable. When this population is significantly different from the trial cohort the external validity comes into question. Should the continuation of the evidence generating process continue these problems might be identified. Post marketing surveillance through phase 4 and comparative effectiveness studies through phase 5 trials are often underperformed in comparison to the RCT. These processes can help identify remote adverse events and define new hypotheses for community level benefits. This review is aimed at exploring the post-marketing scene for CHF therapeutics from an Australian health system perspective. We explore the phases of clinical trials, the level of evidence currently available and options for ensuring greater accountability for community level CHF clinical outcomes.

[PMID: 25343000 PMCID: PMC4205776 DOI: 10.2174/1874192401408010094] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2014] [Revised: 08/25/2014] [Accepted: 08/28/2014] [Indexed: 11/22/2022] Open
Abstract
Objectives: To assess gaps between guidelines and medicine prescription/dosing and referral for defibrillator therapy in patients with left ventricular systolic dysfunction (LVSD). Methods: Outpatient echocardiography reports at an academic hospital centre were screened and outpatients with LVEF<40% were included. A questionnaire was mailed to the patients’ physician, querying prescription/dosing of ACE-inhibitors (ACEi), angiotensin receptor blockers (ARB) and beta-blockers (BB). Patients with LVEF<30% had additional questions on implantable cardiac defibrillator (ICD) referral. Results: Mean age was 69.6+/-12.2 years and mean LVEF was 29.7+/-6.5%. ACEi and/or ARB prescription rate was 260/309(84.1%) versus 256/308(83.1%) for BB (p=NS for comparison). Of patients on ACEi, 77/183(42.1%) were on target dose, compared to 7/45(15.5%) for ARB and 9/254(3.5%) for BB (p<0.01). Of 171/309 patients (55.3%) with LVEF<30%, 72/171(42.1%) had an ICD and 16/171(9.4%) were referred for one. Conclusion: Prescription rates of evidence-based HF medicines are relatively high in outpatients with LVSD referred for echocardiography at this Canadian academic medical centre; however, the proportion of patients at target doses was modest for ACEi and low for ARB and BB. Approximately half of patients who qualify for ICD by EF alone have one or were referred. Important reasons for patients with LVSD not on evidence-based therapy were identified.

The journey of the frail older adult with heart failure: implications for management and health care systems. ACTA ACUST UNITED AC 2014.

Abstract
SummaryThe heart failure epidemic predominantly affects older people, particularly those with concurrent co-morbid conditions and geriatric syndromes. Mortality and heath service utilization associated with heart failure are significant, and extend beyond the costs associated with acute care utilization. Over time, older people with heart failure experience a journey characterized by gradual functional decline, accelerated by unpredictable disease exacerbations, requiring greater support to remain in the community, and often ultimately leading to institutionalization. In this narrative review, we posit that the rate of functional decline and associated health care resource utilization can be attenuated by optimizing the management of heart failure and associated co-morbidities. However, to realize this objective, the manner in which care is delivered to frail older people with heart failure must be restructured, from the bedside to the level of the health care system, in order to optimally anticipate, diagnose and manage co-morbidities.

Abstract
BACKGROUND It is often assumed that differences in the efficacy of treatments between countries (or regions) will be neither negligible nor minor and therefore cannot be overlooked when assessing the potential benefit of treatments in one country (or region) on the basis of trials conducted in another country (or region). AIM To assess differences in the results of cardiovascular trials between Europe and North America on the basis of data from an extensive collection of trials. METHODS A systematic search was conducted of Medline (from the year 2005 to 2008) and the Cochrane Library (from 2000 to 2008) for all meta-analyses of randomized controlled trials aimed at treating and preventing cardiovascular disease. Within each meta-analysis that satisfied given criteria, trial results were compared between Europe and North America with respect to a fatal and/or non-fatal endpoint by forming separate estimates of treatment efficacy for each of these continents. RESULTS The literature search found 59 meta-analyses that satisfied all the inclusion criteria. For most meta-analyses, it was the case that relative to the control, the intervention was more favoured in trials conducted in Europe than in North America with regard to both fatal endpoints (28 out of 43 meta-analyses) and non-fatal endpoints (28 out of 40 meta-analyses). However, it was only with regard to non-fatal endpoints that this imbalance turned out to be statistically significant at the 5% level (P=0.017). Also, the lack of statistically significant differences in trial results between Europe and North America within individual meta-analyses meant that it was not possible to determine for which types of intervention these intercontinental differences are likely to be more pronounced than others. CONCLUSION There is some evidence to support the theory that, relative to controls, interventions are more favoured in cardiovascular trials conducted in Europe than in North America, when treatment efficacy is measured in terms of a non-fatal endpoint. However, the overall support for systematic differences in cardiovascular trial results between Europe and North America is weak, which may be surprising given the amount of data collected.

Abstract
ABSTRACT: Heart failure, a condition that affects up to 20% of older persons residing in long-term care facilities, is an important cause of morbidity, health service utilization and death. Effective and interprofessional heart failure care processes could potentially improve care, outcomes and quality of life and delay decline or hospital admission. This article reviews the clinical aspects of heart failure, and the challenges to the diagnosis and management of this condition in long-term care residents who are frail and are affected by multiple comorbidities.

Abstract
BACKGROUND AND OBJECTIVE It is well known that a hall mark of heart failure is adverse changes in autonomic function. Elevated blood pressure is a powerful predictor of congestive heart failure and other Cardiovascular Disease (CVD) outcomes. In this study, we planned to examine the effects of a 12 week yoga therapy on blood pressure, heart rate, heart rate variability, and rate pressure product (RPP). METHODS Out of 130 heart failure patients recruited for the study, 65 patients were randomly selected to receive 12 week yoga therapy along with standard medical therapy (yoga group). Other patients (n=65) received only standard medical therapy (control group). Heart rate, blood pressure, cardiac autonomic function (by short-term heart-rate variability analysis) and myocardial oxygen consumption (by RPP) were assessed before and after 12 weeks. In the yoga group, 44 patients and in the control group, 48 patients completed the study. RESULTS There was a significant decrease in heart rate, blood pressure and RPP in yoga group compared to control group. Also, LFnu and LF-HF ratio decreased significantly and HFnu increased significantly in yoga group compared to control group. CONCLUSION Twelve-week yoga therapy significantly improved the parasympathetic activity and decreased the sympathetic activity in heart failure patients (NYHA I&II).

One trial (135 patients) compared enalapril with placebo in childhood cancer survivors with asymptomatic anthracycline induced cardiac dysfunction. The other trial (68 patients) compared a two-week treatment of phosphocreatine with a control treatment (vitamin C, ATP, vitamin E, oral coenzyme Q10) in leukaemia patients with anthracycline-induced cardiotoxicity. Both studies had methodological limitations.The RCT on enalapril showed no (statistically) significant differences in overall survival, mortality due to heart failure, development of clinical heart failure and quality of life between treatment and control group. A post-hoc analysis showed a decrease (i.e. improvement) in one measure of cardiac function (left ventricular end systolic wall stress (LVESWS): -8.62% change) compared with placebo (+1.66% change) in the first year of treatment (P = 0.036), but not afterwards. Patients treated with enalapril had a higher risk of dizziness or hypotension (RR 7.17, 95% CI 1.71 to 30.17) and fatigue (Fisher's exact test, P = 0.013).The RCT on phosphocreatine found no differences in overall survival, mortality due to heart failure, echocardiographic cardiac function and adverse events between treatment and control group. AUTHORS' CONCLUSIONS For the effect of enalapril in childhood cancer survivors with asymptomatic cardiac dysfunction, only one RCT is available. Although there is some evidence that enalapril temporarily improves one parameter of cardiac function (LVESWS), it is unclear whether it improves clinical outcomes. Enalapril was associated with a higher risk of dizziness or hypotension and fatigue. Clinicians should weigh the possible benefits with the known side-effects of enalapril in childhood cancer survivors with asymptomatic anthracycline-induced cardiotoxicity.For the effect of phosphocreatine in childhood cancer patients with anthracycline-induced cardiotoxicity, only one RCT is available. Limited data with a high risk of bias showed no significant difference between phosphocreatine and control treatment on echocardiographic function and clinical outcomes.We did not identify any RCTs or CCTs studying other medical interventions for symptomatic or asymptomatic cardiotoxicity in childhood cancer patients or survivors.High-quality studies should be performed.

Abstract
BACKGROUND The number of African American (AA) patients living with heart failure (HF) has been increasing, especially among the economically disadvantaged. Yoga therapy has been found to improve physical and psychological parameters among healthy individuals, but its effect in patients with HF remains unknown. The purpose of this study was to examine the effects of yoga therapy on cardiovascular endurance (VO2peak), flexibility, quality of life (QoL), and inflammatory markers on medically stable HF patients. METHODS Forty patients (38 AA, 1 Asian, and 1 Caucasian) with systolic or diastolic HF were randomized to the yoga group (YG, n = 21) or the control group (CG, n = 19). All patients were asked to follow a home walk program. Premeasurement and postmeasurement included a treadmill stress test to peak exertion, flexibility, interleukin-6 (IL-6), C-reactive protein (CRP), and extracellular superoxide dismutase (EC-SOD). QoL was assessed by the Minnesota Living with Heart Failure Questionnaire (MLwHFQ). RESULTS The statistical analyses (assessed by ANOVA and t-tests) were significant for favorable changes in the YG, compared with those in the CG, for flexibility (P = 0.012), treadmill time (P = 0.002), VO2peak (P = 0.003), and the biomarkers (IL-6, P = 0.004; CRP, P = 0.016; and EC-SOD, P = 0.012). Within the YG, pretest to posttest scores for the total (P = 0.02) and physical subscales (P < 0.001) of the MLwHFQ were improved. CONCLUSIONS Yoga therapy offered additional benefits to the standard medical care of predominantly AA HF patients by improving cardiovascular endurance, QoL, inflammatory markers, and flexibility.

Abstract
BACKGROUND Despite recent advances in pharmacologic and device therapy, morbidity and mortality from heart failure (HF) remain high. Yoga combines physical and breathing exercises that may benefit patients with HF. We hypothesized that an 8-week regimen of yoga in addition to standard medical therapy would improve exercise capacity, inflammatory markers, and quality of life (QoL) in patients with HF. METHODS AND RESULTS New York Heart Association Class I-III HF patients were randomized to yoga treatment (YT) or standard medical therapy (MT). Measurements included a graded exercise test (GXT) to V O(2Peak) and the following serum biomarkers: interleukin-6 (IL-6), high-sensitivity C-reactive protein (hsCRP), and extracellular superoxide dismutase (EC-SOD). The Minnesota Living with Heart Failure Questionnaire (MLHFQ) was administered to assess changes in QoL. A total of 19 patients were enrolled after the initial screening. Of the 19 patients, 9 were randomized to YT and 10 to MT. Patients had a mean EF of 25%. GXT time and V O(2Peak) were significantly improved in the YT versus MT groups (+18% in the YT and -7.5% in MT; P = .03 vs. control and +17 in YT and -7.1 in MT; P = .02, respectively). There were statistically significant reductions in serum levels of IL-6 and hsCRP and an increase in EC-SOD in the YT group (all P < .005 vs. MT). MLHFQ scores improved by 25.7% in the YT group and by 2.9% in the MT group. CONCLUSIONS Yoga improved exercise tolerance and positively affected levels of inflammatory markers in patients with HF, and there was also a trend toward improvements in QoL.

Abstract
As part of the recommended modern post-myocardial infarction (MI) management, including reperfusion strategies, antiplatelet therapy, and beta-blockers, we may wonder whether the impact of early inhibition of the renin-angiotensin system (RAS) is as important as it was 20 years ago. This review demonstrates that significant clinical benefit can be derived from angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) even when added to other currently recommended treatment strategies in post-MI patients. Moreover, the effects of RAS inhibition extend far beyond the early post-MI neurohormonal activation and left ventricular remodeling phases. The favorable effects of RAS inhibition on important prognostic markers such as atrial fibrillation, renal function, and diabetes have recently been unraveled. Post-MI RAS inhibition also benefits all age groups, including elderly patients.

Poor functional status based on the New York Heart Association classification exposes the coronary patient to an elevated risk of ischemic stroke. Am Heart J 2008; 155:515-20. [PMID: 18294489 DOI: 10.1016/j.ahj.2007.10.032] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/11/2007] [Accepted: 10/24/2007] [Indexed: 11/23/2022]
Abstract
BACKGROUND Patients with coronary heart disease (CHD) are at increased risk of stroke. We investigated in a large cohort of patients with CHD the relationship between functional status, as assessed by the New York Heart Association (NYHA) classification, and incident ischemic stroke. METHODS We followed up 15,524 patients with documented CHD, screened for inclusion in a clinical trial (Bezafibrate Infarction Prevention), for 4.8 to 8.1 years. Functional status at baseline was categorized according to the NYHA classification. Among 14,703 patients, free of stroke, with recorded NYHA functional class, 1086 (7.4%) developed an ischemic cerebrovascular event, of whom 604 (4.1%) patients were confirmed to have an ischemic stroke or transient ischemic attack. RESULTS The cumulative rate of ischemic cerebrovascular events increased from 6.7% in patients with NYHA functional class I to 9.2% and 9.7% for patients with NYHA functional classes II and III, respectively (P < .001). Adjustments were made in Cox proportional hazard models for age, sex, body mass index, past myocardial infarction, current smoking, diabetes, hypertension, peripheral vascular disease, percent of cholesterol in high-density lipoprotein, and triglyceride levels. The adjusted hazard ratios associated with NYHA functional class II and III were 1.29 (95% confidence interval 1.12-1.48) and 1.71 (95% confidence interval 1.36-2.15), respectively, as compared with patients with NYHA class I. CONCLUSIONS Our findings indicate that stable coronary patients with even a slight limitation based on the NYHA functional class are exposed to an increased risk of ischemic stroke.

Abstract
BACKGROUND The clinical benefits of cardiac resynchronization therapy (CRT) and primary prophylactic implantable cardioverter defibrillator (ICD) in patients with left ventricular systolic dysfunction (LVSD) are debated. OBJECTIVE To evaluate by a meta-analysis the effect of CRT and prophylactic ICD therapy in patients with LVSD. METHODS Eligible trials evaluating the effect of CRT vs. no-CRT, ICD vs. no-ICD and adding ICD to CRT vs. no-ICD were selected and meta-analyzed. The outcomes were: all cause mortality, cardiac mortality, hospitalization for heart failure and change in exercise tolerance and New York Heart Association class. RESULTS Implantation of CRT reduced all cause mortality odds ratio (OR) = 0.73 (0.60-0.89) p = 0.002 and hospitalization for heart failure OR = 0.60 (0.45, 0.80) p = 0.001, increased peak oxygen consumption by 1.77 (0.32-3.22) ml/kg/min p = 0.017 and improved New York Heart Association class by at least one class with OR = 1.52 (1.30, 1.77) p < 0.0001. Implantation of ICD reduced all-cause mortality OR = 0.75 (0.59-0.96) p = 0.025 and cardiac mortality OR = 0.63 (0.48, 0.82) p = 0.001. Adding ICD to CRT reduced all cause mortality OR = 0.69 (0.53-0.91) p = 0.008. CONCLUSION Selective patients with LVSD benefit from CRT, ICD or both. Further investigations are necessary to clarify which patients benefit most from a single or combined device implantation.

Abstract
The world-wide estimated prevalence of diabetes mellitus for 2025 is of about 300 million, resulting from a higher prevalence of obesity and sedentary lifestyles in the developed world. The group of cardiovascular diseases is responsible for 80% of deaths among diabetic patients. Several authors have suggested that patients with diabetes mellitus have a predisposition to develop a form of cardiomyopathy, known as <<diabetic cardiomyopathy>>, which is not related to ischemic heart disease or hypertension, and may progress to cardiac failure. Such condition is known to be associated with a poor prognosis in patients with diabetes mellitus. The prevalence appears to be high. Thus, tissue Doppler techniques added to conventional echocardiography assessment have estimated it to be as high as 75%. However, the use of echocardiography as a screening tool in the asymptomatic diabetic population is problematic. Biomarkers of cardiac dysfunction have been proposed for diagnosis. In this article, we have assessed the role of biomarkers in the diagnosis of this condition and proposed a diagnostic algorithm that may be useful for the assessment of asymptomatic patients with diabetes.
