Long-term safety and efficacy of anacetrapib in patients with atherosclerotic vascular disease.

AIMS: REVEAL was the first randomized controlled trial to demonstrate that adding cholesteryl ester transfer protein inhibitor therapy to intensive statin therapy reduced the risk of major coronary events. We now report results from extended follow-up beyond the scheduled study treatment period. METHODS AND RESULTS: A total of 30 449 adults with prior atherosclerotic vascular disease were randomly allocated to anacetrapib 100 mg daily or matching placebo, in addition to open-label atorvastatin therapy. After stopping the randomly allocated treatment, 26 129 survivors entered a post-trial follow-up period, blind to their original treatment allocation. The primary outcome was first post-randomization major coronary event (i.e. coronary death, myocardial infarction, or coronary revascularization) during the in-trial and post-trial treatment periods, with analysis by intention-to-treat. Allocation to anacetrapib conferred a 9% [95% confidence interval (CI) 3-15%; P = 0.004] proportional reduction in the incidence of major coronary events during the study treatment period (median 4.1 years). During extended follow-up (median 2.2 years), there was a further 20% (95% CI 10-29%; P < 0.001) reduction. Overall, there was a 12% (95% CI 7-17%, P < 0.001) proportional reduction in major coronary events during the overall follow-up period (median 6.3 years), corresponding to a 1.8% (95% CI 1.0-2.6%) absolute reduction. There were no significant effects on non-vascular mortality, site-specific cancer, or other serious adverse events. Morbidity follow-up was obtained for 25 784 (99%) participants. CONCLUSION: The beneficial effects of anacetrapib on major coronary events increased with longer follow-up, and no adverse effects emerged on non-vascular mortality or morbidity. These findings illustrate the importance of sufficiently long treatment and follow-up duration in randomized trials of lipid-modifying agents to assess their full benefits and potential harms.

Factors associated with smoking cessation in patients with coronary heart disease: a cohort analysis of the German subset of EuroAspire IV survey.

BACKGROUND: Tobacco smoking is one of the most important risk factors of coronary heart disease (CHD). Hence, smoking cessation is considered pivotal in the prevention of CHD. The current study aimed to evaluate smoking cessation patterns and determine factors associated with smoking cessation in patients with established CHD. METHODS: The fourth European Survey of Cardiovascular Disease Prevention and Diabetes investigated quality of CHD care in 24 countries across Europe in 2012/13. In the German subset, smoking cessation patterns and clinical characteristics were repetitively assessed a) during index event due to CHD by medical record abstraction, b) as part of a face-to-face interview 6 to 36 months after the index event (i.e. baseline visit), and c) by telephone-based follow-up interview two years after the baseline visit. Logistic regression analysis was performed to search for factors determining smoking status at the time of the telephone interview. RESULTS: Out of 469 participants available for follow-up, 104 (22.2%) had been classified as current smokers at the index event. Of those, 65 patients (62.5%) had quit smoking at the time of the telephone interview, i.e., after a median observation period of 3.5 years (quartiles 3.0, 4.1). Depressed mood at baseline visit and higher education level were less prevalent amongst quitters vs non-quitters (17.2% vs 35.9%, p = 0.03 and 15.4% vs 33.3%, p = 0.03), cardiac rehabilitation programs were more frequently attended by quitters (83.1% vs 48.7%, p < 0.001), and there was a trend for a higher prevalence of diabetes at baseline visit in quitters (37.5% vs 20.5%, p = 0.07). In the final multivariable model, cardiac rehabilitation was associated with smoking cessation (OR 5.19; 95%CI 1.87 to 14.46; p = 0.002). DISCUSSION: Attending a cardiac rehabilitation program after a cardiovascular event was associated with smoking cessation supporting its use as a platform for smoking cessation counseling and relapse prevention.

[Complete information technology blackout in hospitals : Development of a concept for maintaining patient care]. / Vollausfall der Informationstechnologie im Krankenhaus : Entwicklung eines Konzepts zur Aufrechterhaltung der Patientenversorgung.

The complete blackout of information technology (IT) in a hospital represents a major incident with acute loss of functionality. The immediate consequence is a rapidly progressive loss of treatment capacity. The major priority for the acute management of such an event is to keep patients safe and prevent life-threatening situations. A possibility to channel the uncontrolled loss of treatment capacity in order to achieve the aforementioned protective target is the immediate organization of an analog system for baseline emergency medical care. The switch over from a fully operational routinely functioning system to a reduced emergency state occurs daily in hospitals (night shift, weekends, public holidays) and reflects the controlled reduction of the treatment capacity. This process and the procedures associated with it are universally known, the functions are clearly defined and planned in advance by duty rotas and the interplay of clinics in the organizational schedule is regulated in detail. In order to accomplish this strategy analog instruments are necessary. These must all be conceived, established, practiced and evaluated in advance with the clinics and departments. Ultimately, all isolated IT blackout concepts must be amalgamated into a compatible and functioning total framework. This structure must be maintained for as long as a partially or totally functioning IT has been reinstated.

CRP genetic variants are associated with mortality and depressive symptoms in chronic heart failure patients.

OBJECTIVE: Heart failure (HF) is a complex medical condition with a multitude of genetic and other factors being involved in the pathogenesis. Emerging evidence points to an involvement of inflammatory mechanisms at least in subgroups of patients. The same is true for depression and depressive symptoms, which have a high prevalence in HF patients and are risk factors for the development and outcomes of cardiovascular disease. METHODS: In 936 patients of the Interdisciplinary Network Heart Failure (INH) program, CRP and IL-6 protein blood levels were measured and genetic variants (single nucleotide polymorphisms) of the CRP and IL6 gene analyzed regarding their influence on mortality. RESULTS: Less common recessive genotypes of two single nucleotide polymorphisms in the CRP gene (rs1800947 and rs11265263) were associated with significantly higher mortality risk (p < 0.006), higher CRP levels (p = 0.029, p = 0.006) and increased depressive symptoms in the PHQ-9 (p = 0.005, p = 0.003). Variants in the IL-6 gene were not associated with mortality. CONCLUSION: Our results hint towards an association of less common CRP genetic variants with increased mortality risk, depressive symptoms and peripheral CRP levels in this population of HF patients thereby suggesting a possible role of the inflammatory system as link between poor prognosis in HF and depressive symptoms.

Simple screening tools predict death and cardiovascular events in patients with rheumatic disease.

OBJECTIVES: Patients with rheumatic disease (RD) have an increased mortality risk compared with the general population, mainly due to cardiovascular disease (CVD). We aimed to identify patients at high risk of CVD and mortality by comparing three screening tools suitable for clinical practice. METHOD: In this prospective, single-centre study, consecutive patients with rheumatoid arthritis (RA), systemic autoimmune disease (SAI), or spondyloarthritides (SpA) including psoriatic arthritis underwent a comprehensive cardiovascular risk assessment. Patients were predefined as being at high risk for cardiovascular events or death if any of the following were present: European Systematic COronary Risk Evaluation (SCORE) ≥ 3%, N-terminal pro-brain natriuretic peptide (NT-proBNP) ≥ 200 pg/mL, or any pathological electrocardiogram pattern. RESULTS: The patient population (n = 764) comprised 352 patients with RA, 260 with SAI, and 152 with SpA. After a median follow-up of 5.2 years, 6.0% of RD patients had died (7.0%, 7.2%, and 1.4% of patients in the RA, SAI, and SpA subgroups), and 5.0% had experienced a cardiovascular event (5.0%, 6.4%, and 2.8%, respectively). For all RD patients and the RA and SAI subgroups, NT-proBNP ≥ 200 pg/mL and SCORE ≥ 3% identified patients with a 3.5-5-fold increased risk of all-cause death and cardiovascular events. Electrocardiogram pathology was associated with increased mortality risk, but not with cardiovascular events. CONCLUSION: NT-proBNP ≥ 200 pg/mL or SCORE ≥ 3% identifies RA and SAI patients with increased risk of cardiovascular events and death. Both tools are suitable as easy screening tools in daily practice to identify patients at risk for further diagnostics and closer long-term follow-up.

[Heart failure networks and centers : What does everyday life look like?] / Herzinsuffizienznetzwerke und -zentren : Wie sieht der Alltag aus?

The German Cardiac Society (DGK) and the German Society for Thoracic and Cardiovascular Surgery (DGTHG) jointly advocated the initiation and certification of heart failure (HF) networks in a position statement in 2016. In these networks, supraregional HF centers cooperate with specialized regional HF clinics and registered cardiologists to improve intersectoral treatment of patients with HF. So far predominantly supraregional HF centers have achieved certification but more recently regional clinics as well as registered cardiologists have applied for certification, now enabling the comprehensive establishment of HF networks. In this article the background, the current situation and the future perspectives of HF networks are assessed and approaches for better networking are discussed.

[Cardiac remodeling after myocardial infarction : Clinical practice update]. / Kardiales Remodelling nach Myokardinfarkt : Update für die klinische Praxis.

Heart failure remains a frequent cause of death and is the leading reason for hospitalization in Germany although therapeutic options have significantly increased over the past years particularly in heart failure with reduced ejection fraction. Clinical symptoms are usually preceded by cardiac remodeling, which was originally defined only by left ventricular dilatation and depressed function but is also associated with typical cellular and molecular processes. Healing after acute myocardial infarction is characterized by inflammation, cellular migration and scar formation. Cardiac remodeling is accompanied by adaptive changes of the peripheral cardiovascular system. Since prevention is the primary goal, rapid diagnosis and treatment of myocardial infarction are mandatory. Early reperfusion therapy limits infarct size and enables the best possible preservation of left ventricular function. Standard pharmacotherapy includes angiotensin-converting enzyme inhibitors, angiotensin-1-receptor blockers and beta blockers. In addition, mineralocorticoid receptor antagonists have proven beneficial. Compounds specifically targeting infarct healing processes are currently under development.

[Heart involvement in Friedreich's ataxia]. / Herzbeteiligung bei Friedreich-Ataxie.

Friedreich's ataxia is a rare hereditary disease and although the gene defect has already been identified as a deficiency of the mitochondrial protein frataxin, the pathophysiology is still unknown. Although a multisystem disorder organ involvement is predominantly neurological. Besides the characteristic features of spinocerebellar ataxia the heart is frequently also affected. Cardiac involvement typically manifests as hypertrophic cardiomyopathy, which can progress to heart failure and death. So far most research has focused on the neurological aspects and cardiac involvement in Friedreich's ataxia has not been systematically investigated. Thus, a better understanding of the progression of the cardiomyopathy, cardiac complications and long-term cardiac outcome is warranted. Although no specific treatment is available general cardiac therapeutic options for cardiomyopathy should be considered. The current review focuses on clinical and diagnostic features of cardiomyopathy and discusses potential therapeutic developments for Friedreich's ataxia.

[Assessment of systolic function in patients with poor echogenicity: echocardiographic methods]. / Abschätzung der linksventrikulären systolischen Funktion bei Patienten mit schlechter Bildqualität : Echokardiographische Methoden.

The visual echocardiographic evaluation of left ventricular (LV) systolic function can be cumbersome, especially in patients with poor image quality. This review describes several alternative echocardiographic methods to determine LV systolic function: endocardial border delineation by contrast agents, mitral annular plane systolic excursion, mitral annular velocity derived from tissue Doppler, myocardial performance index, mitral regurgitation derived LV dP/dtMax and estimation of cardiac output by Doppler echocardiography. The review introduces the respective methods along with the presentation of suitable measurements, clinical implications and methodological limitations.

[Holistic therapy of chronic heart failure]. / Ganzheitliche Behandlung der chronischen Herzinsuffizienz.

The rising prevalence and increasing disease-related costs render chronic heart failure a rapidly growing socioeconomic challenge. The concerted action of guideline-adjusted therapy and holistic patient care is essential to achieve improvements in mortality, morbidity, functional status and quality of life of patients with symptomatic heart failure. Holistic care strategies comprise consideration of comorbidities and individual needs, lifestyle recommendations and multidisciplinary management programs for high-risk symptomatic patients in addition to basic medication and surgical therapies. For optimal patient care and coaching, seamless interaction is required between in-hospital treatment and outpatient facilities. Moreover, the palliative needs of heart failure patients need to be considered, a topic that is currently not receiving enough attention.

Long-term outcome of enzyme-replacement therapy in advanced Fabry disease: evidence for disease progression towards serious complications.

OBJECTIVE: The long-term effects of enzyme-replacement therapy (ERT) in Fabry disease are unknown. Thus, the aim of this study was to determine whether ERT in patients with advanced Fabry disease affects progression towards 'hard' clinical end-points in comparison with the natural course of the disease. METHODS: A total of 40 patients with genetically proven Fabry disease (mean age 40 ± 9 years; n = 9 women) were treated prospectively with ERT for 6 years. In addition, 40 subjects from the Fabry Registry, matched for age, sex, chronic kidney disease stage and previous transient ischaemic attack (TIA), served as a comparison group. The main outcome was a composite of stroke, end-stage renal disease (ESRD) and death. Secondary outcomes included changes in myocardial left ventricular (LV) wall thickness and replacement fibrosis, change in glomerular filtration rate (GFR), new TIA and change in neuropathic pain. RESULTS: During a median follow-up of 6.0 years (bottom and top quartiles: 5.1, 7.2), 15 events occurred in 13 patients (n = 7 deaths, n = 4 cases of ESRD and n = 4 strokes). Sudden death occurred (n = 6) only in patients with documented ventricular tachycardia and myocardial replacement fibrosis. The annual progression of myocardial LV fibrosis in the entire cohort was 0.6 ± 0.7%. As a result, posterior end-diastolic wall thinning was observed (baseline, 13.2 ± 2.0 mm; follow-up, 11.4 ± 2.1 mm; P < 0.01). GFR decreased by 2.3 ± 4.6 mL min(-1) per year. Three patients experienced a TIA. The major clinical symptom was neuropathic pain (n = 37), and this symptom improved in 25 patients. The event rate was not different between the ERT group and the untreated (natural history) group of the Fabry Registry. CONCLUSION: Despite ERT, clinically meaningful events including sudden cardiac death continue to develop in patients with advanced Fabry disease.

Complement C3c as a biomarker in heart failure.

INTRODUCTION: Experimental data indicates an important role of the innate immune system in cardiac remodeling and heart failure (HF). Complement is a central effector pathway of the innate immune system. Animals lacking parts of the complement system are protected from adverse remodeling. Based on these data, we hypothesized that peripheral complement levels could be a good marker for adverse remodeling and prognosis in patients with HF. METHODS AND RESULTS: Since complement activation converges on the complement factor C3, we measured serum C3c, a stable C3-conversion product, in 197 patients with stable systolic HF. Subgroups with normal and elevated C3c levels were compared. C3c levels were elevated in 17% of the cohort. Patients with elevated C3c levels exhibited a trend to better survival, slightly higher LVEF, and lower NTpro-BNP values in comparison to patients with normal C3c values. No differences were found regarding NYHA functional class. Significantly more patients with elevated C3c had preexisting diabetes. The prevalence of CAD, arterial hypertension, and atrial fibrillation was not increased in patients with elevated C3c. CONCLUSION: Elevated C3c levels are associated with less adverse remodeling and improved survival in patients with stable systolic heart failure.

[Echocardiography in diabetic cardiomyopathy]. / Echokardiographie bei diabetischer Kardiomyopathie.

The term diabetic cardiomyopathy was initially introduced in the 1980s when evidence was found that diabetes leads to a distinct cardiomyopathy, independent of coronary artery disease or hypertension. The detection of diabetic cardiomyopathy using echocardiography is challenging because no pathognomonic signs exist; however, it is the merit especially of the newer echocardiographic techniques, such as deformation imaging, that it is now possible to describe the morphology and function of diabetic hearts. Unfortunately, no long-term echocardiography studies are available describing disease progression in detail. Therefore, staging and differential diagnosis of diabetic cardiomyopathy remains challenging. This review tries to fill this gap by presenting a possible echocardiographic staging algorithm. Early stages of diabetic cardiomyopathy are marked by a deterioration of longitudinal systolic function and a compensative elevated radial function. Diastolic dysfunction is another early sign. When the disease progresses the functional deterioration is accompanied by morphological changes, such as left ventricular concentric hypertrophy and fibrosis. End stage disease is characterized by reduced ejection fraction and ventricular dilatation. Very late stage can mimic dilative cardiomyopathy.

[Assessment of diastolic heart failure. Current role of echocardiography]. / Beurteilung der diastolischen Herzinsuffizienz. Aktueller Stellenwert der Echokardiographie.

Diastolic heart failure, also known as heart failure with preserved left ventricular ejection fraction (HF-pEF), is responsible for approximately 50 % of all heart failure cases. According to current guidelines the diagnosis HF-pEF requires three criteria: (1) signs or symptoms of heart failure, (2) presence of a normal left ventricular ejection fraction and (3) evidence of diastolic dysfunction. Echocardiography is the diagnostic modality of choice, especially after ruling out other causes of dyspnea, such as pulmonary diseases, heart rhythm disturbances and volume overload. Important echocardiographic parameters for the assessment of diastolic function are atrial dimensions, myocardial mass, mitral inflow pattern, pulmonary vein flow, propagation velocity of mitral inflow and the tissue Doppler of the mitral annulus. Nevertheless, a complete echocardiographic examination should be performed in every patient with heart failure. In general, diastolic dysfunction is frequently associated with increased atrial diameter and left ventricular hypertrophy. In advanced stages pulmonary hypertension can be present. A robust method for evaluation of systolic function in patients with diastolic dysfunction is crucial. The mitral inflow pattern provides various parameters to describe diastolic function (E/A ratio, deceleration time, isovolumetric relaxation time). In case of difficulties to separate a normal from a pseudonormal mitral inflow pattern the Valsalva maneuver can be used. Another valuable parameter for this differentiation is the duration of the backward flow in the pulmonary veins in contrast to forward flow over the mitral valve. Tachycardia or atrial fibrillation is a major problem for grading of diastolic function; however, in patients with atrial fibrillation E/e' is a well-established parameter. In summary, this review provides a detailed overview and discussion of the established and newer echocardiography techniques for the evaluation of diastolic function and provides an algorithm for the assessment of diastolic dysfunction in everyday routine.

[Low flow/low gradient aortic valve stenosis : clinical and diagnostic management]. / "Low-Flow/Low-Gradient"-Aortenklappenstenose : Klinisches und diagnostisches Spektrum.

Low gradient aortic stenoses (AS) represent a special challenge for physicians with respect to an exact diagnosis and optimal therapy. The difficulty lies in the estimation of the severity of AS which is decisive for subsequent treatment and the prognosis. Low flow and low gradient can be due to systolic or diastolic dysfunction by high-grade as well as by medium-grade AS and be of non-valvular origin. The latter group is to be interpreted as pseudoaortic stenosis as long as the low flow can successfully be raised by interventional means. However, only patients in the first group can be expected to profit from valve replacement and for patients in the second group the accompanying diseases must be the focus of therapeutic treatment. Therefore, according to recent European surveys up to 30% of patients with severe AS are undertreated due to false estimation of the severity of stenosis and perioperative risk stratification. Furthermore, follow-up investigations have shown that patients with low flow/low gradient stenosis and borderline-normal ejection fraction (EF) are in an advanced stage of the disease because they have often developed a severe reduction in longitudinal myocardial function and in addition have pronounced myocardial replacement fibrosis due to cardiac remodelling despite a preserved EF. Therefore, aortic valve area, mean pressure gradient and EF alone cannot be taken into consideration for the management of patients with severe AS but a comprehensive assessment of the hemodynamics, such as stroke volume, special functional parameters as well as individual clinical appearance is essential for precise diagnostic and therapeutic decision making.

Secondary prevention in diabetic and nondiabetic coronary heart disease patients: Insights from the German subset of the hospital arm of the EUROASPIRE IV and V surveys.

BACKGROUND: Patients with coronary heart disease (CHD) with and without diabetes mellitus have an increased risk of recurrent events requiring multifactorial secondary prevention of cardiovascular risk factors. We compared prevalences of cardiovascular risk factors and its determinants including lifestyle, pharmacotherapy and diabetes mellitus among patients with chronic CHD examined within the fourth and fifth EUROASPIRE surveys (EA-IV, 2012-13; and EA-V, 2016-17) in Germany. METHODS: The EA initiative iteratively conducts European-wide multicenter surveys investigating the quality of secondary prevention in chronic CHD patients aged 18 to 79 years. The data collection in Germany was performed during a comprehensive baseline visit at study centers in Würzburg (EA-IV, EA-V), Halle (EA-V), and Tübingen (EA-V). RESULTS: 384 EA-V participants (median age 69.0 years, 81.3% male) and 536 EA-IV participants (median age 68.7 years, 82.3% male) were examined. Comparing EA-IV and EA-V, no relevant differences in risk factor prevalence and lifestyle changes were observed with the exception of lower LDL cholesterol levels in EA-V. Prevalence of unrecognized diabetes was significantly lower in EA-V as compared to EA-IV (11.8% vs. 19.6%) while the proportion of prediabetes was similarly high in the remaining population (62.1% vs. 61.0%). CONCLUSION: Between 2012 and 2017, a modest decrease in LDL cholesterol levels was observed, while no differences in blood pressure control and body weight were apparent in chronic CHD patients in Germany. Although the prevalence of unrecognized diabetes decreased in the later study period, the proportion of normoglycemic patients was low. As pharmacotherapy appeared fairly well implemented, stronger efforts towards lifestyle interventions, mental health programs and cardiac rehabilitation might help to improve risk factor profiles in chronic CHD patients.
