BACKGROUND: Beta-blockers refer to a mixed group of drugs with diverse pharmacodynamic and pharmacokinetic properties. They have shown long-term beneficial effects on mortality and cardiovascular disease (CVD) when used in people with heart failure or acute myocardial infarction. Beta-blockers were thought to have similar beneficial effects when used as first-line therapy for hypertension. However, the benefit of beta-blockers as first-line therapy for hypertension without compelling indications is controversial...

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...

The aim of the present study was to investigate whether the serum levels of complements and high-sensitivity C-reactive protein (hs-CRP) in patients with acute myocardial infarction (AMI) are associated with the severity of myocardial injury. Consecutive patients (n=110) with AMI and 33 healthy individuals, who served as control subjects, were enrolled from May 2013 to February 2015. These patients were divided into two groups, those with ST segment elevation MI (STEMI) and those with non-ST segment elevation MI (NSTEMI)...

We have recently demonstrated that NADPH oxidase hyperactivity, NF-κB activation and increased p38 phosphorylation lead to atrophy of glycolytic muscle in heart failure (HF). Aerobic exercise training (AET) is an efficient strategy to counteract skeletal muscle atrophy in this syndrome. Therefore, we tested whether AET would regulate muscle redox balance and protein degradation by decreasing NADPH oxidase hyperactivity, reestablishing NF-κB signaling, p38 phosphorylation and proteasome activity in plantaris muscle of myocardial infarcted-induced HF (MI) rats...

Heart failure (HF) is a debilitating disease in which abnormal function of the heart leads to imbalance of blood demand to tissues and organs. The pathogenesis of HF is very complex and various factors can contribute including myocardial infarction, ischemia, hypertension and genetic cardiomyopathies. HF is the leading cause of death and its prevalence is expected to increase in parallel with the population age. Different kind of therapeutic approaches including lifestyle modification, medication and pacemakers are used for HF patients in NYHA I-III functional class...

PURPOSE OF REVIEW: Ischemic mitral regurgitation (MR), which occurs in about 20-30% patients with a prior myocardial infarction, is associated with worsening heart failure and an increase in cardiovascular mortality. It should be treated surgically if certain hemodynamic severity criteria are met and in patients who continue to experience symptoms of heart failure despite optimal medical therapy. However, current guidelines do not suggest which of the available approaches to mitral valve surgery-mitral valve (MV) repair or replacement (MVR) is superior for this indication...

INTRODUCTION: Obesity is associated with significantly better outcome after acute myocardial infarction (AMI), a phenomenon known as 'obesity paradox'. Tricuspid annular plane systolic excursion (TAPSE) is an echocardiographic measurement of right ventricular (RV) function and has prognostic implications at the time of AMI. METHODS: We examined the difference in RV function among patients admitted with AMI according to obesity status. In a single center cohort analysis of 105 patients admitted between 2010 and 2011 with the diagnosis of AMI...

AIMS: Although beta-blockers can prolong survival in patients with myocardial infarction (MI) and heart failure with reduced left ventricular ejection fraction (HFrEF), use of beta-blockers in patients with diabetes may cause hypoglycaemia and weight gain, which are associated with an increased risk of death and cardiovascular events. METHODS: Using the Bypass Angioplasty Revascularization Investigation 2 Diabetes trial data, we performed Cox proportional hazards analysis to assess the effects of beta-blockers on all-cause mortality in 2,244 patients with type 2 diabetes who had stable coronary heart disease (CHD) with and without a prior history of MI/HFrEF...

Tissue macrophage numbers vary during health versus disease. Abundant inflammatory macrophages destruct tissues, leading to atherosclerosis, myocardial infarction and heart failure. Emerging therapeutic options create interest in monitoring macrophages in patients. Here we describe positron emission tomography (PET) imaging with (18)F-Macroflor, a modified polyglucose nanoparticle with high avidity for macrophages. Due to its small size, Macroflor is excreted renally, a prerequisite for imaging with the isotope flourine-18...

BACKGROUND: Sodium-glucose cotransporter 2 inhibitors (SGLT2i) are a novel category of oral antidiabetic drugs that inhibit renal glucose reabsorption and increase renal glucose excretion, thus lowering plasma glucose levels. This unique mechanism of SGLT2i action is insulin independent, thus improving glycemic control without promoting hypoglycemia in the absence of exogenously administered insulin. METHODS: The present narrative review addresses the putative associations between SGLT2i and several cardiovascular (CV) and microvascular risk factors, as well as their effects on cardiac and renal function...

BACKGROUND: Heart failure with reduced ejection fraction caused by ischemic heart disease is associated with increased morbidity and mortality. It remains unclear whether revascularization by either coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) carries benefits or risks in this group of stable patients compared with medical treatment. METHODS AND RESULTS: We performed a meta-analysis of available studies comparing different methods of revascularization (PCI or CABG) against each other or medical treatment in patients with coronary artery disease and left ventricular ejection fraction ≤40%...

BACKGROUND: Patients with unplanned dialysis start (UPS) have worse clinical outcomes than non-UPS patients, and receive peritoneal dialysis (PD) less frequently. In the OPTiONS study of UPS patients, an educational programme (UPS-EP) aiming at improving care of UPS patients by facilitating care pathways and enabling informed choice of dialysis modality was implemented. We here report on impact of UPS-EP on modality choice and clinical outcomes in UPS patients. METHODS: This non-interventional, prospective, multi-center, observational study included 270 UPS patients from 26 centers in 6 European countries (Austria, Germany, Denmark, France, United Kingdom and Sweden) who prior to inclusion presented acutely, or were being followed by nephrologists but required urgent dialysis commencement by an acutely placed CVC or PD catheter...
