Relation of sex, age and concomitant diseases to drug prescription for heart failure in primary care in Europe

Prevalence of heart failure and trends in its pharmacological treatment between 2000 and 2017 among very old people

PURPOSE

The aim of this study was to describe a population of very old people with heart failure (HF), to analyse the use of cardiovascular drugs over time, and to explore factors influencing cardiovascular drug treatment for this group.

METHODS

All participants with information regarding HF diagnosis were selected from the Umeå 85+/Gerontological Regional Database (GERDA). The people in GERDA are all ≥85 years old. Trained investigators performed structured interviews and assessments. Information regarding medications and diagnoses was obtained from the participants and from medical records. Medical diagnoses were reviewed and confirmed by an experienced geriatrician.

RESULTS

In this very old population, the prevalence of HF was 29.6% among women and 30.7% among men. Between 2000 and 2017, there was an increase in the use of renin-angiotensin (RAS) inhibitors (odds ratio [OR] 1.107, 95% confidence interval [CI] 1.072-1.144) and beta-blockers (BBs) (OR 1.123, 95% CI 1.086-1.161) among persons with HF, whereas the prevalence of loop diuretics (OR 0.899, 95% CI 0.868-0.931) and digitalis (OR 0.864, 95% CI 0.828-0.901) decreased (p < 0.001 for all drug classes). Higher age was associated with lower use of RAS inhibitors and BBs.

CONCLUSION

In this HF population, the use of evidence-based medications for HF increased over time. This may be a sign of better awareness among prescribers regarding the under-prescribing of guidelines-recommended treatment to old people. Higher age associated with a lower prevalence of RAS inhibitors and BBs. This might indicate that further improvement is possible but could also represent a more cautious prescribing among frail very old individuals.

Evaluation of the prescribing practice of guideline-directed medical therapy among ambulatory chronic heart failure patients

BACKGROUND

Studies have demonstrated that heart failure (HF) patients who receive direct pharmacist input as part of multidisciplinary care have better clinical outcomes. This study evaluated/compared the difference in prescribing practices of guideline-directed medical therapy (GDMT) for chronic HF patients between two multidisciplinary clinics-with and without the direct involvement of a pharmacist.

METHODS

A retrospective audit of chronic HF patients, presenting to two multidisciplinary outpatient clinics between March 2005 and January 2017, was performed; a Multidisciplinary Ambulatory Consulting Service (MACS) with an integrated pharmacist model of care and a General Cardiology Heart Failure Service (GCHFS) clinic, without the active involvement of a pharmacist.

RESULTS

MACS clinic patients were significantly older (80 vs. 73 years, p < .001), more likely to be female (p < .001), and had significantly higher systolic (123 vs. 112 mmHg, p < .001) and diastolic (67 vs. 60 mmHg, p < .05) blood pressures compared to the GCHF clinic patients. Moreover, the MACS clinic patients showed more polypharmacy and higher prevalence of multiple comorbidities. Both clinics had similar prescribing rates of GDMT and achieved maximal tolerated doses of angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) in HFrEF. However, HFpEF patients in the MACS clinic were significantly more likely to be prescribed ACEIs/ARBs (70.5% vs. 56.2%, p = 0.0314) than the GCHFS patients. Patients with both HFrEF and HFpEF (MACS clinic) were significantly less likely to be prescribed β-blockers and mineralocorticoid receptor antagonists. Use of digoxin in chronic atrial fibrillation (AF) in MACS clinic was significantly higher in HFrEF patients (82.5% vs. 58.5%, p = 0.004), but the number of people anticoagulated in presence of AF (27.1% vs. 48.0%, p = 0.002) and prescribed diuretics (84.0% vs. 94.5%, p = 0.022) were significantly lower in HFpEF patients attending the MACS clinic. Age, heart rate, systolic blood pressure (SBP), anemia, chronic renal failure, and other comorbidities were the main significant predictors of utilization of GDMT in a multivariate binary logistic regression.

CONCLUSIONS

Lower prescription rates of some medications in the pharmacist-involved multidisciplinary team were found. Careful consideration of demographic and clinical characteristics, contraindications for use of medications, polypharmacy, and underlying comorbidities is necessary to achieve best practice.

Optimization of Heart Failure Treatment by Heart Rate Reduction

Heart failure (HF) treatment should be optimized in addition to guideline-directed and recommended drugs to achieve an appropriate heart rate (i.e. 50−60 bpm) by ivabradine in patients with a heart rate >70 bpm in sinus rhythm and with an ejection fraction ≤35%. Heart rate reduction was to reduce cardiovascular death and HF hospitalization dependent on baseline resting heart rate. In particular in patients at a heart rate >75 bpm, a reduction in cardiovascular death, all-cause death, HF death, HF hospitalization and all-cause hospitalization has been observed. The optimal heart rate achieved appears to be between 50−60 bpm, if well tolerated as in these patients the lowest event rate is observed on treatment. Heart rate reduction is, therefore, a treatable risk factor in chronic HF. Observational studies support the concept that it is a risk indicator in other cardiovascular and non-cardiovascular conditions. Whether heart rate reduction is also modifying risk in other conditions than chronic HF should be explored in prospective clinical trials.

Quality of life assessment in patients with heart failure: validity of the German version of the generic EQ-5D-5L™

BACKGROUND

Chronic heart failure patients typically suffer from tremendous strain and are managed mainly in primary care. New care concepts adapted to the severity of heart failure are a challenge and need to consider health-related quality of life aspects. This is the first psychometric validation of the German EQ-5D-5L™ as a generic instrument for assessing health-related quality of life (HRQOL) in a primary care heart failure patient sample.

METHODS

Confirmatory factor analysis (CFA) was performed on the baseline EQ-5D-5L™ data from the RECODE-HF study (responses to all items from n = 3225 of 3778 patients). Basic CFA models for HRQOL were calculated based on the EQ-5D-5L™ items using the maximum likelihood (ML) and the asymptotic distribution-free method. In an extended CFA, physical activity and depression were added. The basic CFA ML model was verified for the reduced number of cases of the extended CFA model (n = 3064). In analyses of variance the association of the EQ-5D-5L™ visual analogue scale (VAS) and both the German and the British EQ-5D-5L™ crosswalk index with the SF-36 measure of general health were examined. The discriminant validity was analysed using Pearson's chi-squared tests applying the New York Heart Association classification, for the VAS and indices analyses of variance were calculated.

RESULTS

In the basic CFA models the root mean square error of approximation was 0.095 with the ML method, and 0.081 with the asymptotic distribution-free method (Comparative Fit Index > 0.90 for both). Physical activity and depression were confirmed as influential factors in the extended model. The VAS and indices were strongly associated with the SF-36 measure of general health (partial eta-squared 0.525/0.454/0.481; all p <  0.001; n = 3155/3210/3210, respectively), also for physical activity and depression when included together (partial eta-squared 0.050, 0.200/0.047, 0.213/0.051 and 0.270; all p <  0.001; n = 3015/n = 3064/n = 3064, respectively). The discriminant validity analyses showed p-values < 0.001 and small to moderate effect sizes for all EQ-5D-5L™ items. Analyses of variance demonstrated moderate effect sizes for the VAS and indices (0.067/0.087/0.084; all p <  0.001; n = 3110/3171/3171).

CONCLUSION

The German EQ-5D-5L™ is a suitable method for assessing HRQOL in heart failure patients.

Drug treatment of heart failure in the elderly

The prevalence of heart failure increases with age. Changes in the age distribution and growing life expectancy will lead to a further rise. However, data concerning drug treatment of heart failure especially in the elderly are scarce. Subgroup analyses of the heart failure trials suggest that drug therapy in older patients should follow the recommendations in the current guidelines. In doing so, several common comorbidities in these patients (e. g., impaired renal function) have to be considered and may have an influence on the therapy (e. g., drug dose, choice of active pharmaceutical ingredient, etc.). Especially in old, multimorbid patients, possible interaction of drugs might play a substantial role. In many cases the main goal of the therapy, especially in the very elderly, is to improve symptoms and quality of life.

Rationale, design and baseline results of the Treatment Optimisation in Primary care of Heart failure in the Utrecht region (TOPHU) study: a cluster randomised controlled trial

BACKGROUND

Heart failure (HF) is mainly detected and managed in primary care, but the care is considered suboptimal. We present the rationale, design and baseline results of the Treatment Optimisation in Primary care of Heart failure in the Utrecht region (TOPHU) study. In this study we assess the effect of a single training of GPs in the pharmacological management of patients with HF.

METHODS/DESIGN

A cluster randomised controlled trial. Thirty primary care practices are randomly assigned to care as usual or intervention defined as a single training in the up-titration and management of HF drug therapy according to the heart failure guidelines of the European Society of Cardiology (ESC). Patients with a GP's diagnosis of HF will be re-evaluated by an expert panel of two cardiologists and a GP with expertise in HF to come to a definite diagnosis of HF according to the ESC heart failure guidelines. Those with definite HF will be analysed in this study. Drug use will be measured after six months, health status after twelve months, and heart-related hospital admissions and all-cause mortality after two years.

DISCUSSION

Our cluster randomised trial will show whether a single training of GPs improves the pharmacological management of patients with HF and confers beneficial effects on health status after one year, and cardiac hospital admissions and all-cause mortality after two years of follow-up.

Heart failure in younger patients: the Meta-analysis Global Group in Chronic Heart Failure (MAGGIC)

AIM

Our understanding of heart failure in younger patients is limited. The Meta-analysis Global Group in Chronic Heart Failure (MAGGIC) database, which consisted of 24 prospective observational studies and 7 randomized trials, was used to investigate the clinical characteristics, treatment, and outcomes of younger patients.

METHODS AND RESULTS

Patients were stratified into six age categories: <40 (n = 876), 40-49 (n = 2638), 50-59 (n = 6894), 60-69 (n = 12 071), 70-79 (n = 13 368), and ≥80 years (n = 6079). Of 41 926 patients, 2.1, 8.4, and 24.8% were younger than 40, 50, and 60 years of age, respectively. Comparing young (<40 years) against elderly (≥80 years), younger patients were more likely to be male (71 vs. 48%) and have idiopathic cardiomyopathy (63 vs. 7%). Younger patients reported better New York Heart Association functional class despite more severe left ventricular dysfunction (median ejection fraction: 31 vs. 42%, all P < 0.0001). Comorbidities such as hypertension, myocardial infarction, and atrial fibrillation were much less common in the young. Younger patients received more disease-modifying pharmacological therapy than their older counterparts. Across the younger age groups (<40, 40-49, and 50-59 years), mortality rates were low: 1 year 6.7, 6.6, and 7.5%, respectively; 2 year 11.7, 11.5, 13.0%; and 3 years 16.5, 16.2, 18.2%. Furthermore, 1-, 2-, and 3-year mortality rates increased sharply beyond 60 years and were greatest in the elderly (≥80 years): 28.2, 44.5, and 57.2%, respectively.

CONCLUSION

Younger patients with heart failure have different clinical characteristics including different aetiologies, more severe left ventricular dysfunction, and less severe symptoms. Three-year mortality rates are lower for all age groups under 60 years compared with older patients.

An evaluation of the pharmacokinetics and pharmacodynamics of ivabradine for the treatment of heart failure

INTRODUCTION

Ivabradine is a new heart-rate-lowering drug; the aim of this review was to analyze its role in heart failure (HF).

AREAS COVERED

This systematic review on the role of ivabradine in HF is based on material searched and obtained through Pubmed and Medline up to September 2013.

EXPERT OPINION

Heart rate (HR) is a risk factor in patients with HF, and its reduction is considered an important goal of therapy. The BEAUTIFUL trial demonstrated the benefits of ivabradine on prognosis (only on ischemic endpoints) in patients with coronary artery disease (CAD) and left ventricular systolic dysfunction (LVSD) and HR ≥ 60 bpm. In the SHIFT trial, which enrolled patients with LVSD, HF and HR ≥ 70 bpm, ivabradine administration (on top of guideline-based therapy, including β-blockers [BB]) was associated with a reduction of cardiovascular death and hospitalizations for HF, but BB were underutilized. Further studies are needed to test the efficacy of ivabradine in CAD patients with high HR and to shed light on the comparison between ivabradine and a more aggressive therapy with higher doses of BB in HF patients.

Efficacy and safety of ivabradine in chronic heart failure across the age spectrum: insights from the SHIFT study

AIMS

To test whether the efficacy and safety of the selective heart rate-reducing agent ivabradine changes according to age in chronic heart failure (HF) patients.

METHODS AND RESULTS

The ivabradine and placebo arms of SHIFT, which enrolled 6505 chronic HF patients, were combined and age distribution was divided by quartiles to give four groups (<53 years, n = 1522; 53 to <60 years, n = 1521; 60 to <69 years, n = 1750; and ≥69 years, n = 1712). The effects of ivabradine on cardiovascular outcomes, changes in heart rate, and adverse events, particularly bradycardia, were evaluated according to age group. A subgroup (602 patients) underwent 24 h ambulatory ECG Holter monitoring. The relative risk of the primary endpoint (cardiovascular death or hospitalization for worsening HF) was reduced by ivabradine in all age groups, ranging from 38% [hazard ratio (HR) 0.62, 95% confidence interval (CI) 0.50-0.78, P < 0.001] in the youngest patients <53 years to 16% (HR 0.84, 95% CI 0.71-0.99, P = 0.035) in the oldest patients ≥69 years. Ivabradine up-titration reduced heart rate similarly in all age groups, by 11 b.p.m. As anticipated, bradycardia and phosphenes occurred more frequently with ivabradine, at a similar rate whatever the age. In the Holter substudy, there were no episodes of severe bradycardia and no clinically relevant pauses with ivabradine in any age group.

CONCLUSIONS

Age does not limit the appropriate use of ivabradine in patients with chronic HF and systolic dysfunction. The safety and efficacy of ivabradine are comparable across all age groups.

Age and receipt of guideline-recommended medications for heart failure: a nationwide study of veterans

BACKGROUND

Older patients often receive less guideline-concordant care for heart failure than younger patients.

OBJECTIVE

To determine whether age differences in heart failure care are explained by patient, provider, and health system characteristics and/or by chart-documented reasons for non-adherence to guidelines.

DESIGN AND PATIENTS

Retrospective cohort study of 2,772 ambulatory veterans with heart failure and left ventricular ejection fraction <40% from a 2004 nationwide medical record review program (the VA External Peer Review Program).

MAIN MEASURES

Ambulatory use of ACE inhibitors, angiotensin receptor blockers (ARBs), and beta blockers.

RESULTS

Among 2,772 patients, mean age was 73 +/- 10 years, 87% received an ACE inhibitor or ARB, and 82% received a beta blocker. When patients with explicit chart-documented reasons for not receiving these drugs were excluded, 95% received an ACE inhibitor or ARB and 89% received a beta blocker. In multivariable analyses controlling for a variety of patient and health system characteristics, the adjusted odds ratio for ACE-inhibitor and ARB use was 0.43 (95% CI 0.24-0.78) for patients age 80 and over vs. those age 50-64 years, and the adjusted odds ratio for beta blocker use was 0.66 (95% CI 0.48-0.93) between the two age groups. The magnitude of these associations was similar but not statistically significant after excluding patients with chart-documented reasons for not prescribing ACE inhibitors or ARBs and beta blockers.

CONCLUSIONS

A high proportion of veterans receive guideline-recommended medications for heart failure. Older veterans are consistently less likely to receive these drugs, although these differences were no longer significant when accounting for patients with chart-documented reasons for not prescribing these drugs. Closely evaluating reasons for non-prescribing in older adults is essential to assessing whether non-treatment represents good clinical judgment or missed opportunities to improve care.

Influence of sex on treatment and outcome in chronic heart failure

The population is aging, the prevalence of heart failure increases with age, and on average women live longer than men. There is evidence for sex-specific effects of individual, guideline-recommended drugs used for treatment of chronic heart failure. Women are underrepresented in most clinical trials and only a minority of drug applications to regulatory authorities have included sex analyses. The present review focuses on the potential female survival benefit in heart failure, the influence of sex on medical treatment in a broader sense, and the potential benefit to be derived from guideline recommended treatment and common adjunctive heart failure medication.

Current treatment of chronic heart failure in primary care; still room for improvement

RATIONAL AND AIMS: In recent years, guidelines for treatment of patients with chronic heart failure (CHF) have been updated. Insight in current pharmacological and non-pharmacological treatment of CHF in primary care, which was non-optimal in earlier studies, is limited. We aim to describe current pharmacological and non-pharmacological treatment of CHF in primary care.

METHODS

In this cross-sectional observational study, we included a representative sample of 357 patients diagnosed with CHF from 42 primary care practices in the Netherlands. We combined medical record data with data from patient and doctor questionnaires.

RESULTS

Mean age of patients was 75.7 years (SD 10.2), 53% were male, and 73% of patients had mild heart failure (New York Heart Association class I or II). 76.5% of patients received diuretics. Angiotensin-converting enzyme inhibitors were prescribed in 40.6% and angiotensin-II receptor blockers in 20.7%; beta-blockers were prescribed to 54.6%, while 24.9% received spironolactone. Patients with more severe heart failure had a lower probability of being treated according to guideline recommendations. Relevant lifestyle advice was given to 40-60% of the patients, depending on the specific lifestyle advice.

CONCLUSIONS

Implementation of evidence-based pharmacotherapy for heart failure in primary care has improved since clinical guidelines have been updated; especially with respect to prescription of beta-blockers. However, there still seems ample room for improvement, as in the case for providing lifestyle advice.

Challenging the dogma of high target doses in the treatment of heart failure: is more always better?

Current therapeutic guidelines for chronic heart failure (HF) recommend high (if possible, maximum) target doses of angiotensin-converting enzyme (ACE) inhibitors and beta-blockers. This is based on "evidence" from large-scale trials in selected patient populations. In "real life", however, many patients receive doses below defined targets, which is usually classified as "under-treatment". When considering whether everyday practice is suboptimal, an important question arises: is more always better and should dosage recommendations be followed in all patients? The superiority of high vs. low-to-moderate doses of ACE inhibitors and beta-blockers in reducing mortality from chronic HF has not been documented convincingly. In large trials with beta-blockers, the efficacy of below-target doses was not significantly different from that of high doses. With high-dose lisinopril, a reduction in the rate of hospitalizations was achieved at the cost of more adverse events. A combination of ACE inhibitors and angiotensin receptor blockers in chronic HF may also cause more problems than benefits. The risks of high doses of spironolactone, digoxin and diuretics are well-known. Sicker elderly and multimorbid patients often do not tolerate the recommended targets but can still have a good clinical response with an improved outcome at lower doses. Therefore lower-than-target doses may not necessarily be wrong in certain patients and are better than "no doses", for example, failure to prescribe essential heart-failure drugs. Individualized doses of ACE inhibitors and beta-blockers (best in combination) are indicated in most patients with chronic HF. Less rigid application of guideline recommendations may improve their acceptance.

Prescriptions of recommended heart failure medications can be correlated with patient and physician characteristics

BACKGROUND

Translating the findings from heart failure drug trials into clinical practice has been shown to take time. For the generation of a primary care guideline that takes preferences of general practitioners (GPs) and characteristics of their patients into account, it is necessary to identify the associations between patient and physician characteristics with the prescription of the recommended drugs.

METHODS

We searched for patients with chronic heart failure in the electronic patient records of 14 GPs. In multivariate analyses, we examined the prognostic value of patient and physician characteristics for the prescriptions.

RESULTS

In the 708 identified patients with chronic heart failure, prescription rates for angiotensin converting enzyme inhibitors/angiotensin receptor blockers, beta blockers, diuretics, digitalis and aldosterone antagonists were 50%, 39%, 56%, 35%, and 4%, respectively. On the patient level, age, disease severity, comorbidities and concomitant drug intake were differently related to the prescriptions. On the physician level, age, years of clinical experience and organisation of the practice itself played a differentiating role. conclusion: Our study demonstrates associations between patient and physician characteristics with the prescription of the recommended drugs that should be taken into account to translate guideline recommendations for application in general practice.

Trends and inequities in beta-blocker prescribing for heart failure

BACKGROUND

Treatment with specific beta-blockers reduces mortality and hospitalisation in heart failure.

AIM

To describe trends and inequities in beta-blocker prescribing for heart failure.

DESIGN OF STUDY

Repeated cross-sectional analysis of a nationally representative primary care database (DIN-LINK).

SETTING

A total of 152 UK general practices.

METHOD

Prescribing of beta-blockers between 2000 and 2005 was examined among a yearly average of 7294 patients aged>or=50 years who had actively managed heart failure - defined as a recorded diagnosis of heart failure and two prescriptions of an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker during the calendar year. The main outcome was the prescription of a guideline-recommended beta-blocker (bisoprolol, carvedilol, metoprolol, or nebivolol) in the year. Determinants of beta-blocker prescribing were analysed using logistic regression.

RESULTS

Between 2000 and 2005, age-adjusted use of recommended beta-blockers rose from 6.1% to 27.0% in men, and from 4.2% to 21.5% in women. In 2005, younger patients were more likely to be treated; the fully adjusted odds ratio was 4.83 (95% confidence interval=3.78 to 6.17) for patients aged 60-64 years compared with those aged 85 years. Women and patients living in areas of socioeconomic deprivation were less likely to be treated. In 2005, in addition to treatment with guideline-recommended beta-blockers, a further 11.7% of men and 12.5% of women were prescribed other beta-blockers.

CONCLUSION

Recommended beta-blocker use has risen in the UK but remains low and inequitable, with many patients still treated with beta-blockers that are not recommended in guidelines. This suggests further improvements in prescribing are still possible.

Survival trends in men and women with heart failure of ischaemic and non-ischaemic origin: data for the period 1987-2003 from the Swedish Hospital Discharge Registry

AIMS

To investigate gender-specific trends in long-term mortality in patients hospitalized for heart failure (HF).

METHODS AND RESULTS

The Swedish hospital discharge and cause-specific death registers were used to calculate age- and gender-specific trends for long-term prognosis in patients hospitalized with a principal diagnosis of HF from 1987 to 2003. Mortality decreased, mainly during 1987-95, with no further decrease after 2001. Survival in men improved more than in women (P-value for interaction 0.0003), particularly among patients aged <65 years (P-value for interaction: age, gender, and year of hospitalization 0.0003) and more for patients with ischaemic when compared with non-ischaemic HF (P-value for interaction <0.0001). Among men <65 years, the hazard ratio (HR) of dying within 3 years after discharge was 0.40 (95% confidence interval 0.36-0.45) during 1999-2001 when compared with 1987-89. The corresponding HR for women was 0.58 (0.48-0.69). For those discharged during 1999-2001, almost 20% of the patients aged 35-64 years and 40% of those aged 65-84 years died within 3 years.

CONCLUSION

Long-term mortality in HF in Sweden decreased more for men than for women and more for ischaemic than non-ischaemic HF. There was no further decrease after 2001. Long-term mortality after a first hospitalization remained high.

Benefits and safety of candesartan treatment in heart failure are independent of age: insights from the Candesartan in Heart failure--Assessment of Reduction in Mortality and morbidity programme

AIMS

Ageing may affect drug efficacy and safety in patients with heart failure (HF). The Candesartan in Heart failure-Assessment of Reduction in Mortality and morbidity (CHARM) programme offered an opportunity to study the relationship between increasing age and the efficacy and safety of treatment in an uniquely broad spectrum of patients with symptomatic HF and either reduced or preserved left ventricular ejection fraction.

METHODS AND RESULTS

A total of 7599 patients in NYHA Class II-IV HF were randomized to candesartan (target dose 32 mg once daily, mean dose 24 mg) or placebo, including 3169 patients age >70 years. Mean follow-up was 37.7 months. The proportional hazards model was used to estimate the treatment effect on efficacy and safety within five age groups: <50 years (n = 605) (8% of all study patients), 50-59 years (n = 1474) (19%), 60-69 years (n = 2351) (31%), 70-79 years (n = 2474) (33%), and > or =80 years (n = 695) (9%). The risk of cardiovascular (CV) death or HF hospitalization (primary outcome) increased from 24% in the lowest age group to 46% in the highest age group (and mortality from 13 to 42%). The relative reduction in risk of the primary outcome with candesartan (15% in the overall study population) was similar irrespective of age. Consequently, the absolute benefit was greater with advancing age (3.8 patients avoided a primary outcome per 100 patients treated in the lowest age group compared with 6.8 in the highest). Adverse events leading to drug discontinuation were more frequent in the candesartan group: placebo/candesartan risk (%), lowest compared with highest age category: hyperkalemia (0.0/1.6 vs. 0.6/2.7), increased serum creatinine (1.0/3.9 vs. 6.1/5.4) and hypotension (1.7/2.0 vs. 2.8/5.7).

CONCLUSION

Older patients were at a greater absolute risk of adverse CV mortality and morbidity outcomes but derived a similar relative risk reduction and, therefore, a greater absolute benefit from treatment with candesartan, despite receiving a somewhat lower mean daily dose of candesartan. Adverse effects were more common with candesartan than with placebo, although the relative risk of adverse effects was similar across age groups. The benefit to risk ratio for candesartan was thus favourable across all age groups.

Emerging problems of heart failure practice in Japanese women: lessons from the CHART study

BACKGROUND

The prognosis of patients with chronic heart failure (CHF) is poor in both men and women. However, the characteristics of, and effective treatment strategy for, female CHF patients still remain unclear. This study was designed to evaluate the prognosis and characteristics of female patients in a CHF cohort termed the Chronic Heart Failure Analysis and Registry in the Tohoku District.

METHODS AND RESULTS

Of 1,278 patients registered in the cohort, the study population comprised 1,166 symptomatic CHF patients with sufficient data. As compared with male patients, female patients were more likely to be older, have preserved systolic function and non-ischemic etiology of CHF, and underuse standard CHF medications. Although a previous study showed that sex-difference was not a significant prognostic factor in CHF patients, the unadjusted survival analysis revealed an increased event rate in female patients in the present study. Multivariate analysis revealed that older age, diabetes, ventricular tachycardia and anemia were significant prognostic risks in both men and women with CHF.

CONCLUSIONS

Female sex had a significant link with elderly CHF patients. Given the explosive increase in elderly patients in Westernized countries, further studies are needed to elucidate the evidence for treatment of female CHF patients.

Características clínicas de los pacientes diagnosticados de insuficiencia cardíaca crónica asistidos en Atención Primaria. Estudio CARDIOPRES

INTRODUCTION

Scarce information is available on the clinical characteristics and risk factors of patients with chronic heart failure (CHF) attended in Primary Care (PC) setting. The aim of this study was to analyze the clinical characteristics of this population in PC.

PATIENTS AND METHODS

Multicenter, cross-sectional study in patients with CHF, consecutively recruited by 232 physicians in PC. The collected data included sociodemographic, etiologic, clinical and therapeutic variables.

RESULTS

Eight hundred forty seven (847) patients were included (age 73.0 +/- 9.6 years; 50.5% men). Of these, 84.3% had arterial hypertension (AHT), 59.2% hypercholesterolemia and 34.9% diabetes mellitus. The most frequent associated clinical disorders were ischemic heart disease (40.1%) and peripheral artery disease (28.6%). In 69.6% of the patients the physicians knew the type of dysfunction (32.4% systolic, 37.2% diastolic). The main etiologies of CHF were the hypertensive cardiomyopathy (75.0%) and ischemic heart disease (40.1%); the most frequent trigger factor was atrial fibrillation (43.9%). Loop diuretics (72.3%) and angiotensin-converting enzyme inhibitors (60.9%) were the treatments used most and 6.7% of the patients were receiving treatment with beta blockers.

CONCLUSIONS

AHT appears to be primary cause of CHF in PC. Diastolic dysfunction is more frequent than the systolic one, and the PC physicians do not know the cause of the ventricular dysfunction in one third of the cases. Loop diuretics and angiotensin-converting enzyme inhibitors were the most frequently used in these patients; the use of beta blockers in CHF is very scarce in PC.

Prescribing for chronic heart failure in Europe: does the country make the difference? A European survey

PURPOSE

International differences in prescribing patterns for chronic heart failure (CHF) have been demonstrated repeatedly. It is not clear whether these differences arise entirely from patient characteristics or factors related to the country itself, such as health care systems or culture. We aim to assess the role of countries in this international variation, aside from the role of patient characteristics.

METHODS

In this European primary care practice survey (from 1999/2000) 11062 CHF patients from 14 countries were included. The influence of country (corrected for patient characteristics) on prescribed drug regimes was assessed by multinomial logistical regression.

RESULTS

Prescribing of guideline-recommended drug regimes ranged from 28.1% in Turkey to 61.8% in Hungary. Including additional regimes justifiable by patients' co-morbidities, increased overall 'rational' prescribing by 11%, but differences among countries remained similar. Multivariate analysis for one-drug and two-drug regimes explained between 35% and 42% of the total variance, country contributed 7%-8% (p < 0.005). Countries determined the number of drugs used and the likelihood of individual drug regimes. For example, in Czech Republic digoxin alone was more likely to be given than the recommended ACE-inhibitors (OR: 3.45; 95%CI: 2.56-4.64), while the combination of digoxin with ACE-inhibitors was as likely as the recommended combination of ACE-inhibitors and beta-blockers (OR: 1.17; 95%CI: 0.88-1.55).

CONCLUSION

Country of residence clearly influenced prescribed drug volume and choice of drug regimes. Therefore, optimal CHF management cannot be achieved without considering country specific factors. It remains to be established which factors within health-care systems are responsible for these effects.

Prescription patterns in patients with systolic heart failure at hospital discharge: why beta blockers are underprescribed or prescribed at low dose in real life?

Systolic heart failure (SHF) is associated with increased morbidity and mortality. Beta-blockers (BB) were shown to provide mortality benefit in patients with SHF, and currently indicated in all stages of patients with SHF. We evaluated the factors influencing the prescription of BBs at discharge in patients hospitalised with HF. Hospital discharge records of consecutive 1418 patients (996 men, 422 women) with a mean age of 57 +/- 15 years, hospitalised and treated for SHF (EF < 45%), were retrospectively reviewed. Mean age of female (n = 422) and male patients (n = 996) was similar (58 +/- 15 years vs. 58 +/- 14 years, p = 0.654). Mean EF was 33 +/- 7%, and not different for each sex (p = 0.288). BBs were present in 47.4% of patients at hospital discharge, and female patients were more frequently prescribed than men (51.7% vs. 45.7%, p = 0.036). Patients who were prescribed BBs at discharge were younger than those who were not (p = 0.034). Patients who were prescribed BBs at discharge had significantly higher EF than those who were not (p = 0.019). Older patients were prescribed low-dose BBs. Besides, creatinine level was significantly higher in the group who were prescribed low-dose BBs than those who were prescribed high dose. However, EF was significantly lower in the group, who were prescribed low-dose BBs than in those prescribed moderate-high dose (33 +/- 7% vs. 35 +/- 7%, p = 0.023). There exist several factors associated with underuse of this highly recommended medication in patients with HF.

Aldosterone antagonists: the most underutilized class of heart failure medications

BACKGROUND

Aldosterone antagonists have been proven to be beneficial in severe heart failure (HF) as a result of systolic dysfunction. We sought to determine if there is a disparity in their utilization compared with ACE inhibitors and beta-adrenoceptor antagonists (beta-blockers).

METHODS

In the first part of the study, we asked physicians to answer a questionnaire presenting a hypothetical HF patient. In the second part, we reviewed hospital charts of patients with HF exacerbation.

RESULTS

Spironolactone was used less frequently than other drugs. At home, 75.0% of patients were receiving ACE inhibitors, 66.7% received beta-blockers, and 38.2% received spironolactone (p < 0.001). During the admission, 93.1% of patients received ACE inhibitors and 58.3% received spironolactone (p < 0.001).

CONCLUSIONS

Despite good evidence, underutilization of aldosterone antagonists in patients matching the population of the RALES (Randomized Aldactone Evaluation Study) trial persists in both outpatient and inpatient settings. The difference between the usage of ACE inhibitors and spironolactone is significant in patients with systolic dysfunction equally qualifying for both medications.

Drug therapy of chronic heart failure in the elderly: the current state of clinical-trial evidence

PURPOSE OF REVIEW

beta-Blockers, angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, aldosterone receptor antagonists, and digoxin are the most common drug classes used to treat chronic heart failure. We examine current clinical trial evidence concerning heart-failure management in the elderly.

RECENT FINDINGS

beta-Blockers provide significant mortality benefit to elderly heart-failure patients and are remarkably well tolerated. Angiotensin-converting-enzyme inhibitors improve mortality and morbidity in systolic heart failure. However, the risk/benefit relationship of angiotensin-converting-enzyme therapy in the elderly has not been adequately determined. Angiotensin II receptor blockers improve morbidity in elderly and non-elderly chronic heart-failure patients; however, data are limited regarding mortality in these patients. Aldosterone receptor antagonists provide significant mortality benefit to elderly chronic heart-failure patients. Digoxin is beneficial as an additive therapy in the treatment of systolic heart failure regardless of advanced age.

SUMMARY

Agents that provide substantive clinical benefit overall also appear to do so in the elderly, based on subgroup analysis of major trials. There have been very few prospective, placebo-controlled trials specifically in elderly heart-failure patients. Elderly heart-failure patients generally tolerate standard chronic heart-failure therapies well. Standard chronic heart-failure therapies should not be withheld from elderly patients based on concerns regarding efficacy or fear of medication intolerance.

Compliance by referring physicians with recommendations on heart failure therapy from a tertiary center

BACKGROUND

We tested the assumption that general practitioners do not use medication as recommended and do not follow recommendations made by heart failure specialists.

METHODS

The study included 193 stable patients referred to and subsequently seen at our heart failure clinic between 1995 and 2001 with an ejection fraction of 40% or less. They had 1906 visits (1661 with structured follow-up). Recommendations by heart failure specialists regarding medication influencing prognosis and adherence of referring physicians to them were recorded.

RESULTS

Ninety-six percent of patients were taking angiotensin-converting enzyme (ACE) inhibitor/angiotensin-II receptor blocker (ARB) when referred. The prescription rate of beta-blockers and spironolactone increased after publication of large trials (more than 80% in 2001). Doses were inappropriate for both ACE-inhibitors/ARBs (55% +/- 30% of target dose) and beta-blockers (29% +/- 24%). Recommendations were followed closely for dose reduction/discontinuation of all drugs (82%) and start/uptitration of spironolactone (78%). Adherence was less (P < .01) for start/uptitration of ACE inhibitors/ARBs (62%) and beta-blockers (48%). Recommendations regarding single-step start/uptitration were more successful (ACE-inhibitors/ARBs, 70%; beta-blockers, 63%; single-step of both, 67%) than multiple-step uptitration (ACE inhibitors/ARBs, 48%; beta-blocker, 38%; P < .001). This was particularly true if recommendations concerned multiple-step uptitration of both drugs (25%, P < .001). There was no difference between general practitioners and cardiologists.

CONCLUSIONS

Although penetration of drugs beneficial in heart failure was high upon referral, doses were lower than recommended, and recommendations regarding changes were insufficiently adhered to by the referring physicians. Simple, one-step recommendations were better implemented and may be combined with direct prescriptions during control visits to guarantee adequate medical therapy.

Cardiovascular diseases in women: a statement from the policy conference of the European Society of Cardiology

Cardiovascular diseases (CVD) are the leading cause of mortality both in men and women. In Europe, about 55% of all females' deaths are caused by CVD, especially coronary heart disease and stroke. Unfortunately, however, the risk of heart disease in women is underestimated because of the perception that women are 'protected' against ischaemic heart disease. What is not fully understood is that women during the fertile age have a lower risk of cardiac events, but this protection fades after menopause thus leaving women with untreated risk factors vulnerable to develop myocardial infarction, heart failure, and sudden cardiac death. Furthermore, clinical manifestations of ischaemic heart disease in women may be different from those commonly observed in males and this factor may account for under-recognition of the disease. The European Society of Cardiology has recently initiated an extensive 'Women at heart' program to coordinate research and educational initiatives on CVD in women. A Policy Conference on CVD in Women was one of the first steps in the development of this program. The objective of the conference was to collect the opinion of experts in the field coming from the European Society of Cardiology member countries to: (1) summarize the state-of-the-art from an European perspective; (2) to identify the scientific gaps on CVD in women; and (3) to delineate the strategies for changing the misperception of CVD in women, improving risk stratification, diagnosis, and therapy from a gender perspective and increasing women representation in clinical trials. The Policy Conference has provided the opportunity to review and comment on the current status of knowledge on CVD in women and to prioritize the actions needed to advance this area of knowledge in cardiology. In the preparation of this document we intend to provide the medical community and the stakeholders of this field with an overview of the more critical aspects that have emerged during the discussion. We also propose some immediate actions that should be undertaken with the hope that synergic activities will be implemented at European level with the support of national health care authorities.

Implementation of evidence–based therapy in patients with systolic heart failure from 1998–2000

BACKGROUND

In recent years, the incidence of systolic heart failure has increased. Besides a complete revascularization, guideline-based medication represents the most effective therapeutic approach.

AIM

Analysis of adherence of guideline-recommended and actual medication during inpatient cardiac rehabilitation as well as under subsequent outpatient conditions.

METHODS

From 01/1998 to 12/ 2000, 1346 consecutive patients (64 +/- 10 years, 73% male, LVEF 36.3 +/- 8%, 88% ischemic, 6.7% valvular cardiomyopathy, 5.3% other causes, 11.8% atrial fibrillation) were included in a singlecenter prospective register. Medication was recorded at discharge and after the follow-up period of 731 +/- 215 days. Trends in prescription rates were analyzed based on nonparametric correlations (Spearman's-Rho). Changes in medication from in- to outpatient settings were analyzed using exact McNemar test.

RESULTS

At discharge 75.3% (67.9%/68.9%/ 86.6% in 1998/1999/2000, p <0.001) of the patients were treated as recommended. This rate dropped to 68.3% at followup (p <0.0001). Mortality within the follow-up period was low (12.6%).

CONCLUSION

It could be shown that from 1998 to 2000 inpatient guideline conformity was implementable adequately. Outpatient conformity was significantly lower. Although a high proportion of correctly prescribed CHF medication could be demonstrated, a further effort to improve guideline adherence in the management of heart failure patients is desirable.

Practical recommendations for the use of ACE inhibitors, beta-blockers, aldosterone antagonists and angiotensin receptor blockers in heart failure: Putting guidelines into practice

Surveys of prescribing patterns in both hospitals and primary care have usually shown delays in translating the evidence from clinical trials of pharmacological agents into clinical practice, thereby denying patients with heart failure (HF) the benefits of drug treatments proven to improve well-being and prolong life. This may be due to unfamiliarity with the evidence-base for these therapies, the clinical guidelines recommending the use of these treatments or both, as well as concerns regarding adverse events. ACE inhibitors have long been the cornerstone of therapy for systolic HF irrespective of aetiology. Recent trials have now shown that treatment with beta-blockers, aldosterone antagonists and angiotensin receptor blockers also leads to substantial improvements in outcome. In order to accelerate the safe uptake of these treatments and to ensure that all eligible patients receive the most appropriate medications, a clear and concise set of clinical recommendations has been prepared by a group of clinicians with practical expertise in the management of HF. The objective of these recommendations is to provide practical guidance for non-specialists, in order to increase the use of evidenced based therapy for HF. These practical recommendations are meant to serve as a supplement to, rather than replacement of, existing HF guidelines.

The relevance of comorbidities for heart failure treatment in primary care: A European survey

AIM

To assess the impact of comorbidities on chronic heart failure (CHF) therapy.

METHODS

The IMPROVEMENT-HF survey included 11,062 patients from 100 primary care practices in 14 European countries. The influence of patient characteristics on drug regimes was assessed with multinomial logistical regression.

RESULTS

Combined drug regimes were given to 48% of CHF patients, consisting of 2.2 drugs on average. Patient characteristics accounted for 35%, 42% and 10% of the variance in one-, two- and three-drug regimes, respectively. Myocardial infarction (MI), atrial fibrillation (AF), diabetes, hypertension, and lung disease influenced prescribing most. AF made all combinations containing beta-blockers more likely. Thus for single drug regimes, MI increased the likelihood for non-recommended beta-blocker monotherapy (OR 1.3; 95% CI 1.2-1.4), while for combination therapy recommended regimes were most likely. For both hypertension and diabetes, ACE-inhibitors were the most likely single drug, while the most likely second drugs were beta-blockers in hypertension and digoxin in diabetes.

CONCLUSIONS

Patient characteristics have a clear impact on prescribing in European primary care. Up to 56% of drug regimes were rational taking patient characteristics into account. Situations of insufficient prescribing, such as patients post MI, need to be addressed specifically.
