RESUMO

BACKGROUND: Heart failure is heterogeneous in aetiology, pathophysiology, and presentation. Despite this diversity, clinical trials of patients hospitalized for HF deal with this problem as a single entity, which may be one reason for repeated failures. METHODS: The first EuroHeart Failure Survey screened consecutive deaths and discharges of patients with suspected heart failure during 2000-2001. Patients were sorted into seven mutually exclusive hierarchical presentations: (1) with cardiac arrest/ventricular arrhythmia; (2) with acute coronary syndrome; (3) with rapid atrial fibrillation; (4) with acute breathlessness; (5) with other symptoms/signs such as peripheral oedema; (6) with stable symptoms; and (7) others in whom the contribution of HF to admission was not clear. RESULTS: The 10,701 patients enrolled were classified into the above seven presentations as follows: 260 (2%), 560 (5%), 799 (8%), 2479 (24%), 1040 (10%), 703 (7%), and 4691 (45%) for which index-admission mortality was 26%, 20%, 10%, 8%, 6%, 6%, and 4%, respectively. Compared to those in group 7, the hazard ratios for death during the index admission were 4.9 (p ≤ 0.001), 4.0 (p < 0.001), 2.2 (p < 0.001), 2.1 (p < 0.001), 1.4 (p < 0.04) and 1.4 (p = 0.04), respectively. These differences were no longer statistically significant by 12 weeks. CONCLUSION: There is great diversity in the presentation of heart failure that is associated with very different short-term outcomes. Only a minority of hospitalizations associated with suspected heart failure are associated with acute breathlessness. This should be taken into account in the design of future clinical trials.

RESUMO

BACKGROUND: Anaemia is common among patients with heart failure (HF) and is an important prognostic marker. AIM: We sought to determine the prognostic importance of anaemia in a large multinational pooled dataset of prospectively enrolled HF patients, with the specific aim to determine the prognostic role of anaemia in HF with preserved and reduced ejection fraction (HF-PEF and HF-REF, respectively). DESIGN: Individual person data meta-analysis. METHODS: Patients with haemoglobin (Hb) data from the MAGGIC dataset were used. Anaemia was defined as Hb < 120 g/l in women and <130 g/l in men. HF-PEF was defined as EF ≥ 50%; HF-REF was EF < 50%. Cox proportional hazard modelling, with adjustment for clinically relevant variables, was undertaken to investigate factors associated with 3-year all-cause mortality. RESULTS: Thirteen thousand two hundred and ninety-five patients with HF from 19 studies (9887 with HF-REF and 3408 with HF-PEF). The prevalence of anaemia was similar among those with HF-REF and HF-PEF (42.8 and 41.6% respectively). Compared with patients with normal Hb values, those with anaemia were older, were more likely to have diabetes, ischaemic aetiology, New York Heart Association class IV symptoms, lower estimated glomerular filtration rate and were more likely to be taking diuretic and less likely to be taking a beta-blocker. Patients with anaemia had higher all-cause mortality (adjusted hazard ratio [aHR] 1.38, 95% confidence interval [CI] 1.25-1.51), independent of EF group: aHR 1.67 (1.39-1.99) in HF-PEF and aHR 2.49 (2.13-2.90) in HF-REF. CONCLUSIONS: Anaemia is an adverse prognostic factor in HF irrespective of EF. The prognostic importance of anaemia was greatest in patients with HF-REF.

RESUMO

BACKGROUND: Heart failure (HF) and chronic obstructive pulmonary disease (COPD) frequently coexist, with undefined prognostic and therapeutic implications. We investigated clinical profile and outcomes of patients with chronic HF and COPD, notably the efficacy and safety of ivabradine, a heart rate-reducing agent. METHODS: 6505 ambulatory patients, in sinus rhythm, heart rate ≥ 70 bpm and stable systolic HF were randomised to placebo or ivabradine (2.5 to 7.5mg bid). Multivariate Cox model analyses were performed to compare the COPD (n=730) and non-COPD subgroups, and the ivabradine and placebo treatment effects. RESULTS: COPD patients were older and had a poorer risk profile. Beta-blockers were prescribed to 69% of COPD patients and 92% of non-COPD patients. The primary endpoint (PEP) and its component, hospitalisation for worsening HF, were more frequent in COPD patients (HRs f, 1.22 [p=0.006]; and 1.34 [p<0.001]) respectively, but relative risk was reduced similarly by ivabradine in both COPD (14%, and 17%) and non-COPD (18% and 27%) patients (p interaction=0.82, and 0.53, respectively). Similar effect was noted also for cardiovascular death. Adverse events were more common in COPD patients, but similar in treatment subgroups. Bradycardia occurred more frequently in ivabradine subgroups, with similar incidence in patients with or without COPD. CONCLUSIONS: The association of COPD and HF results in a worse prognosis, and COPD represents a barrier to optimisation of beta-blocker therapy. Ivabradine is similarly effective and safe in chronic HF patients with or without COPD, and can be safely combined with beta-blockers in COPD.

RESUMO

BACKGROUND: Nesiritide is approved in the United States for early relief of dyspnea in patients with acute heart failure. Previous meta-analyses have raised questions regarding renal toxicity and the mortality associated with this agent. METHODS: We randomly assigned 7141 patients who were hospitalized with acute heart failure to receive either nesiritide or placebo for 24 to 168 hours in addition to standard care. Coprimary end points were the change in dyspnea at 6 and 24 hours, as measured on a 7-point Likert scale, and the composite end point of rehospitalization for heart failure or death within 30 days. RESULTS: Patients randomly assigned to nesiritide, as compared with those assigned to placebo, more frequently reported markedly or moderately improved dyspnea at 6 hours (44.5% vs. 42.1%, P=0.03) and 24 hours (68.2% vs. 66.1%, P=0.007), but the prespecified level for significance (P≤0.005 for both assessments or P≤0.0025 for either) was not met. The rate of rehospitalization for heart failure or death from any cause within 30 days was 9.4% in the nesiritide group versus 10.1% in the placebo group (absolute difference, -0.7 percentage points; 95% confidence interval [CI], -2.1 to 0.7; P=0.31). There were no significant differences in rates of death from any cause at 30 days (3.6% with nesiritide vs. 4.0% with placebo; absolute difference, -0.4 percentage points; 95% CI, -1.3 to 0.5) or rates of worsening renal function, defined by more than a 25% decrease in the estimated glomerular filtration rate (31.4% vs. 29.5%; odds ratio, 1.09; 95% CI, 0.98 to 1.21; P=0.11). CONCLUSIONS: Nesiritide was not associated with an increase or a decrease in the rate of death and rehospitalization and had a small, nonsignificant effect on dyspnea when used in combination with other therapies. It was not associated with a worsening of renal function, but it was associated with an increase in rates of hypotension. On the basis of these results, nesiritide cannot be recommended for routine use in the broad population of patients with acute heart failure.

RESUMO

BACKGROUND: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited heart disease in which mutations affecting Plakophilin-2 (PKP2) are the most frequently detected. However, pathogenicity of variants is not always fully determined. PKP2 encodes two isoforms, the longest (PKP2b) includes the alternatively spliced exon 6, which is routinely screened for molecular diagnosis, despite the absence of data on cardiac expression of PKP2 isoforms. OBJECTIVE: To examine the pathogenicity of PKP2 exon 6 mutations by focusing on a missense variant located in this exon. METHODS AND RESULTS: The PKP2 heterozygous p.Arg490Trp variant was identified in two unrelated ARVC probands (absent from 470 controls). In silico analysis suggested that PKP2 exon 6 is an Alu-derived sequence with very low expression level. PKP2a mRNA, which does not include the sequence encoded by exon 6, was the dominant isoform transcribed; at western blot analysis PKP2A was the only clearly detectable isoform in all human heart samples analysed (from six different controls and the proband). Moreover, in the proband's sample, p.Arg490Trp was not associated with aberrant exon 6 splicing or mutant mRNA downregulation. Finally, a heterozygous missense variant (p.Glu2343Lys) in Desmoplakin was identified in this proband and is likely to be the disease-causing mutation. CONCLUSION: PKP2A was shown to be the major isoform expressed in human heart tissue and PKP2B protein was undetectable. The results strongly suggest that p.Arg490Trp and other variants located in PKP2 exon 6 may not be disease causing. Variant splicing also has important consequences for the interpretation of mutation analysis and genetic counselling in ARVC and other hereditary cardiac diseases.

RESUMO

AIM: Insufficient control of cardiovascular risk factors is observed in primary care. The goal of the present study was to evaluate the association of abdominal obesity with achievement of treatment targets for HbA(1c), LDL cholesterol, triglycerides, HDL cholesterol and blood pressure in primary care. METHODS: In this cross-sectional observational epidemiological study, primary-care practitioners completed a questionnaire covering demographic and socioeconomic data, medical history, drug treatment, and clinical and biological characteristics for 3351 patients (1630 men and 1721 women). Therapeutic targets were HbA(1c) <7%, LDL cholesterol <1.6g/L, triglycerides <1.5 g/L and SBP/DBP <140/90 mmHg. Multivariate analyses were performed to assess the relationship between waist circumference and a lack of cardiovascular risk-factor control. RESULTS: The patients' mean ages were 58+/-14 years and 55+/-16 years for men and women, respectively. A large waist circumference was positively and significantly (P<0.0001 for all) associated with diabetes, hypercholesterolaemia, hypertriglyceridaemia, low HDL cholesterol and hypertension. The prevalence of patients not achieving therapeutic targets increased across waist-circumference quartiles. For treated patients, the odds ratios (95% CI) (adjusted for age, gender, education, smoking status and medical specialty) for not achieving treatment targets were 17.6 (2.2-142) for triglycerides, 2.8 (1.3-6.1) for HbA(1c) and 1.4 (0.9-2.0) for blood pressure on comparisons with extreme quartiles of waist-circumference distribution. CONCLUSION: In primary care, a lack of control of triglycerides, HbA(1c) and, to a lesser extent, blood pressure increases with waist circumference independently of confounders. This suggests that abdominal obesity is associated of poor results in the treatment of diabetes and hypertriglyceridaemia.

RESUMO

OBJECTIVE: To determine gender differences in diagnostic workup and treatment of patients with heart failure. DESIGN: Retrospective. METHOD: The data of 8914 patients (of whom 4166 women; 47%) with confirmed heart failure, who participated in the Euro Heart Survey on Heart Failure (EHS-HF) were analysed. RESULTS: On average, the women in the study were older than the men (75 versus 68 years) and less often suffered from a coronary heart disease (56 versus 66%). Women were more likely to have hypertension (59 versus 49%), diabetes mellitus (29 versus 26%), or valvular heart disease (42 versus 36%). Fewer women had an ultrasonographic evaluation of ventricular function (59 versus 74%) and, among those investigated, fewer had left ventricular systolic dysfunction (44 versus 72%). These observed results remained stable after adjustment for age and other possible confounding variables. Medication with a documented positive impact on survival, i.e. angiotensin converting enzyme (ACE) inhibitors, beta-blocking drugs and the diuretic spironolactone, was prescribed less often to women than men. Women, however, received symptomatic medication such as other diuretics and digoxin more often than men. CONCLUSION: Men and women with heart failure differed with respect to a number of relevant clinical characteristics. Clinicians should take good note of this and take measures to prevent differences in patient care.

RESUMO

Heart failure is a major public health problem. Heart failure with preserved systolic function (HF-PSF) is a common form, which is difficult to diagnose. Results of recent studies show that HF-PSF has a poor prognosis, with an annual survival rate similar to that of heart failure with left ventricular systolic dysfunction. Despite these findings, the therapeutic management of HF-PSF is not clearly defined. We will discuss in this review of the literature the current therapeutic management of HF-PSF, including the role of precipitating factors such as hypertension, myocardial ischaemia and supraventricular arrhythmias, and the main results of epidemiological registries and randomized controlled clinical trials in this disease. Only four large therapeutic trials have assessed the impact of different classes of drugs (digoxin, angiotensin II converting enzyme inhibitors, angiotensin II receptors type I blockers and beta-blockers) on morbidity and mortality in HF-PSF. Results of these trials are disappointing. Apart from the beta-blockers, the other three classes of drugs did not show benefit on the outcome of the disease. Moreover, the results of the beta-blocker trial are controversial as a mixed population of heart failure with and without preserved systolic function was studied. Finally, the current therapeutic management of patients with HF-PSF is still based on our pathophysiological knowledge: education, low salt diet, diuretics, slowing heart rate and controlling triggering factors. Other large randomized controlled multicenter trials, which may help us in the understanding of HF-PSP and its therapeutic management, are ongoing.

RESUMO

OBJECTIVES: This study evaluated gender differences in clinical characteristics, treatment and outcome among patients with heart failure, and to what extent these differences are due to age and differences in left ventricular (LV) function. Although gender differences are observed among heart failure patients, few studies have been adequately powered to investigate these differences. METHODS: A total of 8914 (out of 10 701) patients (47% women) from the Euro Heart Survey on Heart Failure with confirmed diagnosis of heart failure were included in the analyses. RESULTS: Women were older (74.7 vs 68.3 years, p<0.001), and less often had evidence of coronary artery disease (56% vs 66%, age-adjusted odds ratio (OR) 0.62; 95% CI 0.57 to 0.68). Women were more likely to have hypertension, diabetes, or valvular heart disease. Fewer women had an investigation of LV function (59% vs 74%, age-adjusted OR 0.67; 95% CI 0.61 to 0.74), and, among those investigated, fewer had moderate/severe left ventricular systolic dysfunction (44% vs 71%, age-adjusted OR 0.35; 95% CI 0.32 to 0.39). Drugs with a documented impact on survival, that is ACE-inhibitors and beta-blockers, were given less often to women, even in the adjusted analysis (OR 0.72; 95% CI 0.61 to 0.86 and OR 0.76; 95% CI 0.65 to 0.89, respectively). 12-week mortality was similar for men and women. CONCLUSIONS: Fewer women had an assessment of LV function, but, when investigated, women had better ventricular function. Women were less often treated with evidence-based drugs, even after adjustment for age and important clinical characteristics. Clinicians need to be aware of deficiencies in the treatment of women with heart failure and measures should be taken to rectify them.

RESUMO

Conduction defects are usually secondary to elective aging of the conduction pathways. However, some familial and genetic forms are now being described. Here we report a particular electrocardiographic pattern in four members of the same family over three generations, naturally leading to the suspicion of a hereditary origin. The ECG appearance is very specific and includes conduction defects (RBBB and occasionally left anterior hemiblock), short PR interval, pseudo appearance of atrial hypertrophy, and occasionally sinus dysfunction or supraventricular extrasystole. Gene analysis identified a R302Q mutation of the gamma2 subunit producing AMP protein kinase, coded by the gene PRKAG2. This is a wrong sense mutation present in the heterozygous state in each of those displaying the ECG anomalies, and is transmitted in an autosomal dominant fashion. The clinical picture here appears to constitute a clinical entity distinct from those previously described as being associated with mutations of the PRKAG2 gene, without any left ventricular hypertrophy or Wolff-Parkinson-White syndrome.

RESUMO

AIMS: This study aimed at describing usual conditions of carvedilol use in heart failure (HF) patients. METHODS: KEOPS was a one-year, multi-centre, prospective pharmaco-epidemiological study in carvedilol treated HF patients recruited by private cardiologists. RESULTS: Two thousand nine patients (mean age: 68) with heart failure were included by 401 cardiologists. 64% of patients were in class II of NYHA and 27% in class III, 87% of patients presented stable heart failure for at least four weeks. Contraindication to beta blocking was observed in 24% of patients, mean left ventricular fraction of ejection was 39% and only 39% of patients had mean left ventricular fraction of ejection<35%. Co-medications included a diuretic agent, ACE inhibitor or ARB in 68% of cases. Eighty three percent of patients had a titration of carvedilol (median duration=1 20 days). Thirty percent reached the recommended maximal dose. The dose of carvedilol at the titration's visit for all the patients (patient in stop included) was on average 30.5 +/- 22.1 mg/day with a median on 25 [confidence interval: 23-27] During the year of follow-up, 10% of patients have stopped the treatment (3% of patients having reached the maximum recommended dose of carvedilol versus 13% for the others), for cardiovascular reasons in 50% of patients (aggravation of heart failure: 28%, symptomatic arterial hypotension: 9%, symptomatic bradycardia: 5%). Finally, symptomatology of patients has improved during the study (59% of patients in class mild to severe at inclusion, versus 36% at the end of the observation), especially for the 30% of patients followed at one year and having reached the maximum recommended dose of carvedilol. Only in univariate analysis, patients with an inclusion high weight (>85 kg) were likely less to reach recommended maximal dose (37.2 versus 8.7%, p-value<0.0001), the patients with systolic heart failure had more chance than the patients with diastolic heart failure to reach the recommended maximal dose (31 versus 17.4%, p-value=0.006), in the same way, the lack of auricular supported more the reach of recommended maximal dose (31.2 versus 24.1%, p-value=0.018) CONCLUSION: KEOPS study suggests an improvement of usual conditions of carvedilol compared to the last investigation but the persistence of prescription outside medical authorization and less dosage of this product compared with clinical studies.

RESUMO

BACKGROUND: Recent registries have shown that recommended drugs for the treatment of chronic heart failure (CHF) are under-prescribed in daily practice. AIMS: To determine prescription rates of CHF drugs, and to assess predictive factors for drug prescription using data from a large panel of French cardiologists. METHODS AND RESULTS: We included 1919 outpatients, with NYHA class II-IV heart failure and a left ventricular ejection fraction <40%. The most frequently prescribed drugs were diuretics (83%), angiotensin converting enzyme inhibitors (ACE-I) (71%), beta-blockers (65%), spironolactone (35%) and angiotensin receptor blockers (ARB) (21%); 61% of patients received a combination of a beta-blocker and an ACE-I or ARB. Target doses were reached in 49% of the patients for ACE-I, but in only 18% for beta-blockers and in 9% for ARBs. Multivariate analyses showed that age >75 years was an independent factor associated with under-prescription of ACE-I-ARBs, beta-blockers or spironolactone. Renal failure was associated with a lower prescription of ACE-I-ARB and spironolactone, and asthma was a predictor of under-prescription of beta-blockers. CONCLUSIONS: In this contemporary survey, prescription rates of CHF drugs were higher than previously reported. However, dosages were lower than those recommended in guidelines. Age remained an independent predictor of under-prescription of CHF drugs.

RESUMO

AIMS: To compare glucose control over 18 months between rosiglitazone oral combination therapy and combination metformin and sulphonylurea in people with Type 2 diabetes. METHODS: RECORD, a multicentre, parallel-group study of cardiovascular outcomes, enrolled people with an HbA(1c) of 7.1-9.0% on maximum doses of metformin or sulphonylurea. If on metformin they were randomized to add-on rosiglitazone or sulphonylurea (open label) and if on sulphonylurea to rosiglitazone or metformin. HbA(1c) was managed to < or = 7.0% by dose titration. A prospectively defined analysis of glycaemic control on the first 1122 participants is reported here, with a primary outcome assessed against a non-inferiority margin for HbA(1c) of 0.4%. RESULTS: At 18 months, HbA(1c) reduction on background metformin was similar with rosiglitazone and sulphonylurea [difference 0.07 (95% CI -0.09, 0.23)%], as was the change when rosiglitazone or metformin was added to sulphonylurea [0.06 (-0.09, 0.20)%]. At 6 months, the effect on HbA(1c) was greater with add-on sulphonylurea, but was similar whether sulphonylurea was added to rosiglitazone or metformin. Differences in fasting plasma glucose were not statistically significant at 18 months [rosiglitazone vs. sulphonylurea -0.36 (-0.74, 0.02) mmol/l, rosiglitazone vs. metformin -0.34 (-0.73, 0.05) mmol/l]. Increased homeostasis model assessment insulin sensitivity and reduced C-reactive protein were greater with rosiglitazone than metformin or sulphonylurea (all P < or = 0.001). Body weight was significantly increased with rosiglitazone compared with sulphonylurea [difference 1.2 (0.4, 2.0) kg, P = 0.003] and metformin [difference 4.3 (3.6, 5.1) kg, P < 0.001]. CONCLUSIONS: In people with diabetes, rosiglitazone in combination with metformin or sulphonylurea was demonstrated to be non-inferior to the standard combination of metformin + sulphonylurea in lowering HbA(1c) over 18 months, and produces greater improvements in C-reactive protein and basal insulin sensitivity but is also associated with greater weight gain.

RESUMO

The aim of this study was to validate a two-dimensional echocardiographic score for left ventricular hypertrophy in familial hypertrophic cardiomyopathy (HCM) by fast CT scan and to study the diagnostic value by an indexed threshold value in affected and genotyped families in comparison with the classical diagnostic method of maximal wall thickness (E max). The study was performed successively in two patient groups with HCM. The echo/CT scan population comprised 26 patients. They underwent echocardiography and Imatron CT scanning. The E max and 2D echo score (sum of the thickness of 4 segments) were measured by echocardiography and compared to the left ventricular mass obtained by the CT method. The 2D echo score was closely correlated to the CT left ventricular mass (r = 0.85) with a higher correlation coefficient than the E max (r = 0.78). The echo/generic population comprised 109 genotyped adults with an identified mutation. The E max and 2D echo score were measured. The genotype was the reference for diagnosis. A theoretical value of the 2D echo score was determined in healthy individuals by a multiple linear regression model of ages, sex and body surface area. A threshold value for abnormality was established after analysis of the ROC. The sensitivity and specificity were 63% and 100% respectively for E max and 73% and 96% respectively for the indexed 2D echo score. The improvement in sensitivity was marked in young adults (< 50 years) with 69% for the indexed 2D echo score versus 54% for E max, p < 0.04. The authors conclude that the indexed 2D score has been validated as an index of hypertrophy by the Imatron CT and has a better diagnostic value than E max, especially in young adults. This echocardiographic criterion could be proposed as an alternative diagnostic sign for screening families.

RESUMO

Heart failure, a frequent disease in the elderly, has a pejorative prognosis. Clinical diagnosis is complicated by atypical or difficult-to-interpret symptoms and by the concomitant presence of other diseases, particularly cognitive impairment, neurological disorders and diseases of the musculoskeletal system. Among the additional investigations, echocardiography remains underused. Impairment of diastolic left ventricular function is frequent. The usual laboratory tests must include calculation of the creatinine clearance, which is indispensable for dosage adjustment of certain drugs (ACE inhibitors, digoxin, spironolactone). The value of plasma natriuretic peptide assays as diagnostic tools has not been determined in elderly or very elderly populations and the plasma B-type natriuretic peptide increases with age. Comprehensive geriatric assessment is essential in order to screen for concomitant diseases and determine the patient's degree of dependence. The general objectives of treatment remain applicable to the elderly subject: improvement in the quality of life, reduction of mortality and the number and duration of hospitalisations, and slowing disease progression. In the frail elderly subject, symptom alleviation is to be the primary objective. In the absence of specific studies on elderly or very elderly subjects, most of the recommendations have been extrapolated from the data based on the evidence generated in younger populations. The dietary rules are to be more flexible than those used for younger subjects, particularly in order to prevent the risk of denutrition induced by strict salt-free diets. Special precautions for the use of heart failure drugs are due to comorbidities and the pharmacokinetic and pharmacodynamic changes related to aging. Drugs dosage increase is to be cautious and carefully monitored for adverse reactions. The therapeutic programmes in which multidisciplinary teams are involved reduce the number and duration of hospitalisations and the costs generated by the disease.

RESUMO

Heart failure is a major health problem which often concerns the elderly. Prevalence of heart failure with preserved systolic function is increasing and varies from 40 to 50%. In the literature, and in the large epidemiological studies, it is commonly designed with the term of "diastolic heart failure", even if a precise analysis of diastolic function is not performed. A diagnostic algorithm is proposed in order to better define the concept of heart failure with preserved systolic function. It consists of seven steps from symptoms and clinical signs to the echocardiographic analysis of diastolic function, in order to confirm the definition of heart failure with preserved systolic function.

RESUMO

BACKGROUND AND OBJECTIVE: The MAHLER survey examined the impact of the European guidelines for the treatment of chronic heart failure (CHF). Especially, the trial addressed the question whether adherence to treatment guidelines leads to a reduction in the rate of CHF and cardiovascular (CV) hospitalization. The present sub-study presents the Germany specific data of the MAHLER study and compares the results with the results in other European countries. PATIENTS AND METHOD: The gobal adherence index (GAI) shows the proportion of correctly prescribed heart failure medications per patient. Class adherence indicators for angiotensin-converting enzyme (AC)-inhibitors, beta-blockers, spironolactone, diuretics and cardiac glycosides and general adherence indicators (GAI3 adherence to first three classes of heart failure medications, GAI5 adherence to five classes) were constructed. In the German sub-study, 251 patient were included, who were seen by 21 cardiologists in private practice (mean age 68,6 + 10,4 years; 173 man, 78 woman; 158 NYHA II; 91 NYHA III, 2 NYHA IV). RESULTS: Mean adherence to CHF therapy guidelines was 63 % for GAI3, 62 % for GAI5. Compared to the other MAHLER-study countries, Germany was on place two and three concerning GAI3 and GAI5, respectively. Strong adherence to treatment guidelines in Germany led to a reduction of CHF and CV hospitalization rate by 40 % (p < 0.033). Thus, the German data confirm the results of the international study indicating that a good GAI3 performance is an independent predictor of time to hospitalization. Hitherto, the relative risk for hospitalization was higher for CHF patients in Germany than for patients in all other European countries. CONCLUSIONS: In Germany like in other European countries, guideline adherence for CHF therapy leads to a reduction in hospitalization rate.
