BACKGROUND: Impaired cardiac autonomic function has been linked to adverse outcomes in patients with acute coronary syndromes (ACS) but is not included in clinical risk models. This is the first study to investigate whether point-of-care testing of cardiac autonomic function by means of short-term deceleration capacity (DC) of heart rate improves risk assessment in patients with suspected ACS. METHODS: 1821 patients with suspected ACS were prospectively enrolled if they were older than 17 years and in sinus rhythm...

Hypertension is the most common chronic cardiovascular condition with increasing prevalence all over the world. Treatment of patients at risk requires a multimodal therapeutic concept to adjust blood pressure, including systematic identification of secondary causes of hypertension or pseudo-resistance, lifestyle modification, polypharmacy, and as well as accompanying risk factors and comorbidities. The present review discusses recent studies on patients with increased cardiovascular risk potentially influencing future treatment strategies...

BACKGROUND: The benefit of revascularization for functional recovery depends on the presence of viable myocardial tissue. OBJECTIVE: Myocardial deformation imaging allows determination of myocardial viability. METHODS: In a first approach, we assessed the optimal cutoff value to determine preserved viability by layer-specific echocardiographic myocardial deformation imaging at rest and low-dose dobutamine (DSE) echocardiography: regional endocardial circumferential strain (eCS) <-19% at rest was as accurate as eCS at DSE...

Short QT syndrome is a malignant cardiac disease characterized by the presence of ventricular tachyarrhythmias leading to syncope and sudden cardiac death. Currently, international guidelines establish diagnostic criteria when QTc is below 340 ms. This entity is one of the main diseases responsible for sudden cardiac death in the pediatric population. In recent years, clinical, genetic and molecular advances in pathophysiological mechanisms related to short QT syndrome have improved diagnosis, risk stratification, and preventive measures...

BACKGROUND: Non-vitamin K antagonist oral anticoagulants (NOACs) are at least as effective and safe as vitamin K antagonists (VKAs) for stroke prevention in atrial fibrillation (AF). All pivotal trials have compared NOACs to warfarin. However, other VKAs are commonly used, for instance phenprocoumon. PATIENTS AND METHODS: A retrospective cohort study using a German claims database assessed the comparative risks of bleeding leading to hospitalization during therapy with NOACs and phenprocoumon in AF patients...

OBJECTIVE: Circulating microRNAs (miRNAs) have been implicated in both heart failure and atherosclerotic disease. The aim of this study was to examine associations between heart failure specific circulating miRNAs, atherosclerotic disease and cardiovascular-related outcome in patients with heart failure. METHODS: The levels of 11 heart failure-specific circulating miRNAs were compared in plasma of 114 heart failure patients with and without different manifestations of atherosclerotic disease...

BACKGROUND: The use of noninvasive diagnostics in coronary artery disease remains underdeveloped. To date, there is no simple and inexpensive method that can lead to a reliable diagnosis. Aside from costly and elaborate imaging techniques, exercise ECG, with its rather moderate sensitivity and specificity, is the main diagnostic method available. METHODS: In this prospective study of 109 patients, the diagnostic value of cardiogoniometry (CGM), a three-dimensional, computer-analyzed vector cardiogram, was determined before and after physical stress, and the results were compared with those obtained from a stress test...

BACKGROUND: Predictors for the need of permanent pacemaker implantation (PPMI) in the context of transcatheter aortic valve implantation (TAVI) are not well defined yet. We evaluated the impact of conduction disturbances, calcium volume of the device landing zone, oversizing and implantation depth on PPMI after TAVI with the balloon-expandable Edwards Sapien 3 (ES3). METHODS AND RESULTS: 335 consecutive patients undergoing transfemoral TAVI with the ES3 for the treatment of symptomatic severe aortic stenosis were included (clinicaltrials NCT02162069)...

AIMS: Recent randomized trials have documented the superiority of TAVR-particularly via transfemoral access-over SAVR in patients with severe aortic stenosis considered to have a high or intermediate operative risk of death. We sought to assess in-hospital outcomes of patients with severe aortic stenosis and a low risk of operative mortality undergoing routine surgical aortic valve replacement (SAVR) or transcatheter aortic valve replacement (TAVR). METHODS AND RESULTS: We performed a propensity-score matched comparison of all patients undergoing first-time treatment by SAVR or transfemoral TAVR (TF-TAVR) in 2014 in Germany who had a logistic EuroSCORE (logES) ≤ 10%, considered to reflect low surgical risk...

INTRODUCTION: Peripartum cardiomyopathy (PPCM) is a rare cardiomyopathy characterized by an acute reduction in left ventricular ejection fraction (LVEF). Sudden deaths during the course of PPCM are reported to be elevated, the underlying mechanisms remains unknown. The aim of the present multi-centre study was to evaluate the arrhythmia burden in a multi-centre approach in patients with PPCM using a wearable cardioverter/defibrillator (WCD). METHODS AND RESULTS: Forty-nine patients from 16 German centres with newly diagnosed PPCM and LVEF ≤35% receiving a WCD were included in this retrospective analysis...

BACKGROUND: Inspiratory and peripheral muscle training improves muscle strength, exercise tolerance, and quality of life in patients with chronic heart failure (HF). However, studies investigating different workloads for these exercise modalities are still lacking. OBJECTIVE: To examine the effects of low and moderate intensities on muscle strength, functional capacity, and quality of life. DESIGN: A randomized controlled trial. METHODS: Thirty-five patients with stable HF (aged >18 years, NYHA II/III, LVEF <40%) were randomized to: non-exercise control group (n = 9), low-intensity training group (LIPRT, n = 13, 15% maximal inspiratory workload, and 0...

AIMS: Hepatitis C virus (HCV) has been associated with cardiomyopathies. Former anti-HCV therapies employing interferon could have serious side effects in patients with advanced heart failure since interferon may adversely impact upon cardiac function. We, therefore, examined whether the novel, interferon-free and highly virus-selective anti-HCV combination therapy might be applicable even in advanced or end-stage heart failure. METHODS AND RESULTS: In a retrospective series of HCV-positive patients admitted to our institution with suspected cardiac disease, coronary, valvular or hypertensive heart disease was diagnosed in 70/146 (47...

BACKGROUND: Successful chronic total occlusion (CTO) revascularization has been associated with prognostic benefits. Whether the extent of coronary artery disease interferes with these benefits has not been investigated yet. AIMS: We sought to compare the survival after percutaneous coronary intervention (PCI) for CTO between patients with multi- (MVD) and single-vessel disease (SVD). METHODS: A total of 2002 consecutive patients undergoing CTO PCI between 01/2005 and 12/2013 were identified and stratified according to the presence/absence of MVD...

BACKGROUND: Iron deficiency (ID) and anaemia are common in heart failure (HF). The prospective, observational PReP registry (Prävalenz des Eisenmangels bei Patienten mit Herzinsuffizienz) studied prevalence and clinical impact of ID and anaemia in HF outpatients attending cardiology practices in Germany. METHODS AND RESULTS: A total of 42 practices enrolled consecutive patients with chronic HF [left ventricular ejection fraction (LVEF) ≤45%]. ID was defined as serum ferritin <100 µg/l, or serum ferritin ≥100 µg/l/<300 µg/l plus transferrin saturation <20%, and anaemia as haemoglobin <13 g/dl (12 g/dl) in men (women)...

BACKGROUND: Sudden cardiac death (SCD) is frequent in patients with heart failure due to dilated cardiomyopathy (DCM). Implantable cardioverter/defibrillator (ICD) device therapy is currently used for primary prevention. However, publication of the DANISH trial has recently given reason for doubt, showing no significant improvement in all-cause mortality in comparison to contemporary medical therapy. METHODS: We performed a meta-analysis of all randomized controlled trials comparing ICD therapy to medical therapy (MT) for primary prevention in DCM...

BACKGROUND: Frailty and malnutrition are common in patients with heart failure (HF), and are associated with adverse outcomes. We studied the prognostic value of three malnutrition and three frailty indices in patients admitted acutely to hospital with HF. METHODS: 265 consecutive patients [62% males, median age 80 (interquartile range (IQR): 72-86) years, median NTproBNP 3633 (IQR: 2025-6407) ng/l] admitted with HF between 2013 and 2014 were enrolled. Patients were screened for frailty using the Derby frailty index (DFI), acute frailty network (AFN) frailty criteria, and clinical frailty scale (CFS) and for malnutrition using the geriatric nutritional risk index (GNRI), controlling nutritional status (CONUT) score and prognostic nutritional index (PNI)...
