Nebivolol (NEB) is one of the top-sold prescription drugs belonging to the third generation of beta-blockers. However, so far, occurrence data in the environment are lacking. Within this study NEB has been found for the first time in effluent samples of wastewater treatment plants in Germany with an average concentration of 13 ng L(-1). Its photodegradation behavior in the environment and in technical processes is largely unknown. To fill this gap, three different UV treatment procedures (UV-C at 254 nm, UV-B at 312 nm and UV-A at 365 nm) were investigated in three different matrices: pure water, pure water in presence of the hydroxyl radical (OH) scavenger tert...

Hypertension is a leading cause of morbidity and mortality worldwide. A major pathophysiological factor contributing to hypertension is reduced nitric oxide (NO) bioavailability. Strategies to address this pathophysiological mechanism could offer significant advantages. Areas covered: In this review we aimed at examining a variety of drugs (statins, beta-adrenergic receptor blockers, calcium channel blockers, angiotensin converting enzyme inhibitors, angiotensin II type-1 receptor blockers) used to treat hypertension and other cardiovascular diseases, particularly with respect to their potential of increasing NO bioavailability and activity in the cardiovascular system...

Parenteral beta-blocker therapy via continuous infusion has shown promising results for improved outcomes for patients with septic shock. As patients with septic shock may require multiple intravenous medications, compatibility is necessary to co-infuse these medications through a y-site connector. The purpose of this study was to examine the physical compatibility of select intravenous drugs used for patients with septic shock combined with various intravenous beta-blockers including esmolol, labetalol, and metoprolol through a simulated y-site infusion...

We performed a nested case-control study in a cohort of antihypertensive drug users to assess the association between discontinuation of different antihypertensive agents and the risk of acute myocardial infarction (AMI). Cases and controls were drawn from the Utrecht Cardiovascular Pharmacogenetics database. Patients who were hospitalised for their first AMI were considered cases and controls were not hospitalised for AMI. Antihypertensive users were defined as current users if the index date (date of AMI) fell within the prescribed duration or as discontinuers if this date fell outside the prescribed duration...

Antihypertensives are widely prescribed and could influence kidney stone risk by altering urinary calcium excretion. However, the impact of different classes of antihypertensives on kidney stone risk is unknown. To assess this impact, we conducted a retrospective, population-based cohort study using linked health administrative databases. Individuals aged >65 years who initiated one of the four antihypertensive classes (that is, angiotensin-converting enzyme inhibitors (ACEis)/angiotensin receptor blockers (ARBs), beta-blockers, calcium channel blockers or thiazide diuretics) were included...

Introduction: Despite clear guidelines recommendations, most patients with heart failure and reduced ejection-fraction (HFrEF) do not attain guideline-recommended target doses. We aimed to investigate characteristics and for treatment-indication-bias corrected clinical outcome of patients with HFrEF that did not reach recommended treatment doses of ACE-inhibitors/Angiotensin receptor blockers (ARBs) and/or beta-blockers. Methods and results: BIOSTAT-CHF was specifically designed to study uptitration of ACE-inhibitors/ARBs and/or beta-blockers in 2516 heart failure patients from 69 centres in 11 European countries who were selected if they were suboptimally treated while initiation or uptitration was anticipated and encouraged...

Patients with cardiovascular disease (CVD) often have multiple comorbid conditions that may interact with each other, confound the choice of treatments, and reduce mortality. Chronic obstructive pulmonary disease (COPD) is one of the most important comorbidities of CVD, which causes serious consequences in patients with ischemic heart disease, stroke, arrhythmia, and heart failure. COPD shares common risk factors such as tobacco smoking and aging with CVD, is associated with less physical activity, and produces systemic inflammation and oxidative stress...

BACKGROUND: We conducted an exploratory analysis of osteoarthritis progression among medication users in the Osteoarthritis Initiative to identify interventions or pathways that may be associated with disease modification and therefore of interest for future clinical trials. METHODS: We used participants from the Osteoarthritis Initiative with annual medication inventory data between the baseline and 36-month follow-up visit (n = 2938). Consistent medication users were defined for each medication classification as a participant reporting at all four annual visits that they were regularly using an oral prescription medication at the time of the visit...

BACKGROUND: Cardiac arrhythmias are one of the main causes of death in ChCP and other dilated cardiomyopathies. Previous studies demonstrated that ventricular arrhythmias are associated with the presence of autoantibodies with beta-adrenergic activity, Ab-β. OBJECTIVES: The aim of this study was to investigate whether Ab-β, present in chronic chagasic patients (ChCP), induce cardiac arrhythmias in the pharmacological type-2 long QT syndrome model (LQTS-2). METHODS/RESULTS: The LQTS2 was established by perfusion of Tyrode saline solution with a potassium channel blocker E-4031 (5μM) in isolated rabbit hearts or in rabbit cardiac strips, in order to record ECG or action potential, respectively...

BACKGROUND: Catamenial epilepsy is a common central nervous system disease in female, which is influenced by the 17-β-estradiol (estrogen) level during the menstrual cycle. Low level (<0.05ng/ml) of estrogen normally accompanies with the perimenstrual classification of catamenial epilepsy, however, without clear mechanism. In previous studies, estrogen has been demonstrated to possess widely regulatory effects on potassium channels. Here, the effect of 17-β-estradiol on modulating inwardly rectifying K(+) (Kir) currents was investigated in cultured hippocampal neurons...

BACKGROUND: Patients with stable angina not controlled by monotherapy with nitrates, beta blockers, or calcium channel blockers are often treated with combinations of these drugs. There may be adverse effects from, or contraindications to, the use of combinations. In low risk groups, medical treatment appears to be as good an option as percutaneous transluminal coronary angioplasty in terms of averting myocardial infarction, death, or subsequent revascularization. Revascularization procedures are too costly or inaccessible for many patients in developing countries therefore effective and safe medical treatment is needed...

BACKGROUND/AIMS: Heart rate variability (HRV) has been linked to mortality in maintenance hemodialysis (HD) patients, but it is less clear whether HRV is associated with major adverse cardiovascular events (MACEs) and hospitalization. METHODS: This study enrolled 179 maintenance HD patients. HRV was measured to assess its prognostic significance in relation to MACEs and hospitalization. RESULTS: During the follow-up period of 33.3 ± 6.7 months, 36 (20...

BACKGROUND: Human epidermal growth receptor 2 (HER2) targeted therapies have survival benefit in adjuvant and metastatic HER2 positive breast cancer but are associated with cardiac dysfunction. Current U.S. Food and Drug Administration recommendations limit the use of HER2 targeted agents to patients with normal left ventricular (LV) systolic function. METHODS: The objective of the SAFE-HEaRt study is to evaluate the cardiac safety of HER2 targeted therapy in patients with HER2 positive breast cancer and mildly reduced left ventricular ejection fraction (LVEF) with optimized cardiac therapy...

PURPOSE: Beta-blocker use is common in the cases with coronary artery bypass surgery. According to the literature, beta-blockers have positive effects but may cause erectile dysfunction (ED). The most commonly used beta-blockers in ischemic cardiac disease are nebivolol and metoprolol. In our clinic, we aimed to compare the effects of nebivolol and metoprolol succinate on ED in the sexually active cases with coronary artery bypass surgery. METHODS: In our clinic, a total of 119 patients with coronary artery bypass surgery were included in the study...

The fight against cancer has never appeared more optimistic with multiple ongoing advances in cancer therapeutics; however, the prevention of cardiotoxicity from these treatments, both old and new, is a major focus of recent research. We recommend conceptualizing the prevention of cardiotoxicity as binary whereby primary prevention involves a uniform application of preventative efforts to anyone receiving a potentially cardiotoxic drug and secondary prevention directed towards those with left ventricular dysfunction, whether symptomatic or not...

BACKGROUND & AIMS: Controversy exists on the impact of non-selective beta-blockers (NSBBs) on survival in patients with ascites. We assessed whether NSBB treatment affects survival in a cohort of 316 consecutive patients with ascites undergoing evaluation for liver transplantation. METHODS: Consecutive patients with cirrhosis and ascites assessed for liver transplantation between 2011-2014 were retrospectively evaluated. Cox regression and competing risk analysis were performed to identify predictors of survival...

PURPOSE: Identifying atrial fibrillation (AF) in outpatients treated with oral anticoagulants (OACs) from claims databases is challenging when the outpatient indication is not available, as OACs are also prescribed for deep vein thrombosis/pulmonary embolism (DVT/PE) that may be treated in the ambulatory setting. An algorithm was developed to identify AF in outpatients initiating OAC from medico-administrative data. METHODS: Among patients initiating OAC in 2013 in the French healthcare databases, those treated for orthopaedic indications were excluded...

PURPOSE: Survival following ovarian cancer diagnosis is generally low; understanding factors related to prognosis could be important to optimize treatment. The role of previously diagnosed comorbidities and use of medications for those conditions in relation to prognosis for ovarian cancer patients has not been studied extensively, particularly according to histological subtype. METHODS: Using pooled data from fifteen studies participating in the Ovarian Cancer Association Consortium, we examined the associations between history of hypertension, heart disease, diabetes, and medications taken for these conditions and overall survival (OS) and progression-free survival (PFS) among patients diagnosed with invasive epithelial ovarian carcinoma...
