Background: Exaggerated beat-to-beat variability of ventricular action potential duration (APD) is linked to arrhythmogenesis. Sympathetic stimulation has been shown to increase QT interval variability, but its effect on ventricular APD in humans has not been determined. Methods and Results: Eleven heart failure patients with implanted bi-ventricular pacing devices had activation-recovery intervals (ARI, surrogate for APD) recorded from LV epicardial electrodes under constant RV pacing. Sympathetic activity was increased using a standard autonomic challenge (Valsalva) and baroreceptor indices were applied to determine changes in sympathetic stimulation...

BACKGROUND: Tardive akathisia (TA) is a subtype of tardive syndrome, and its etiology is still uncertain. Sevikar is an anti-hypertensive agent containing both amlodipine and olmesartan, and has never been reported to have an adverse reaction in patients with tardive syndrome. CASE PRESENTATION: A 57-year-old woman who took Sevikar for hypertension for 10 years developed TA one and a half years before receiving any psychiatric treatment. After switching from Sevikar to bisoprolol, she reported obvious improvement in her akathisia...

Clinical efficacy and adverse effects of the β-blocking agents, carvedilol, bisoprolol, and metoprolol were analyzed theoretically, and then compared quantitatively, for the purpose of determining their proper use for chronic heart failure. Initially, we evaluated occupancy binding to the β1 and β2 receptors (Фss(β1) and Фss(β2)) by these drugs. Thereafter, we examined the relationship between Фss(β1) values and left ventricular ejection fraction (LVEF) increase rate to determine efficacy. The result showed that the efficacy with carvedilol could be attained with a lower Фss(β1) value than the others...

AIM: to evaluate the ocular hypotensive efficacy of systemic beta-blockers in primary glaucoma patients suffering from arterial hypertension (AH). MATERIAL AND METHODS: The study included 29 patients with POAG (58 eyes) aged from 47 to 83 years. Patients with stage I-III POAG received instillations of prostaglandin analogs and carbonic anhydrase inhibitors. All POAG patients also suffered from arterial hypertension and were prescribed selective beta-blockers (metoprolol, bisoprolol, or nebivalol) as monotherapy or as part of combination therapy (if the target arterial pressure had not been achieved under the initial treatment)...

In patients suffering from systemic arterial hypertension, coronary artery disease, or heart failure, beta-blockers and angiotensin-convertase enzyme inhibitors play a major therapeutic and preventive role. Coronary artery disease remains the leading cause of mortality in industrialized countries. Unless adapted preventive strategy, notably pharmacological interventions, cardiovascular events in these patients remain high. One reason for this relative failure is represented by non-adherence to treatment. A treatment consisting in an association in one pill of several different molecules should confer a higher treatment compliance and thus efficacy...

BACKGROUND: Heart rate has been associated with prognosis in patients with heart failure with reduced ejection fraction (HFREF) and sinus rhythm; whether this also holds true in patients with atrial fibrillation (AF) is unknown. HYPOTHESIS: To evaluate cardiac rhythm and baseline heart rate and the influence of outcome in patients with HFREF enrolled in the Cardiac Insufficiency Bisoprolol Study II. METHODS: In total, 2539 patients were stratified according to their baseline heart rhythm (AF or sinus rhythm) and into quartiles of heart rate (≤70 bpm, 71-78 bpm, 79-90 bpm, and >90 bpm)...

RATIONALE: Continuously refining and advancing the strategies and methods employed in sports drug testing is critical for efficient doping controls. Besides improving and expanding the spectrum of target analytes, alternative test matrices have warranted in-depth evaluation as they commonly allow for minimal-/non-invasive and non-intrusive sample collection. In this study, the potential of exhaled breath (EB) as doping control specimen was assessed. METHODS: EB collection devices employing a non-woven electret-based air filter unit were used to generate test specimens, simulating a potential future application in doping controls...

Aims: Beta-blockers vary in pharmacodynamics and pharmacokinetic properties. It is unknown whether specific types are associated with increased perioperative risks. We evaluated perioperative risks associated with beta-blocker subtypes, overall and in patient subgroups. Methods and results: We performed a Danish Nationwide cohort study, 2005-2011, of patients treated chronically with beta blocker (atenolol, bisoprolol, carvedilol, metoprolol, propranolol, or other) prior to non-cardiac surgery...

AIMS: Beta-blockers are recommended for the treatment of chronic heart failure (CHF). However, it is disputed whether beta-blockers exert a class effect or whether there are differences in efficacy between agents. METHODS AND RESULTS: 6010 out-patients with stable CHF and a reduced left ventricular ejection fraction prescribed either bisoprolol, carvedilol or metoprolol succinate were identified from three registries in Norway, England, and Germany. In three separate matching procedures, patients were individually matched with respect to both dose equivalents and the respective propensity scores for beta-blocker treatment...

We examined the involvement of adrenoceptors in the automaticity of the pulmonary vein myocardium, which probably plays a crucial role in the generation of atrial fibrillation. The automatic activity of the myocardium in guinea pig pulmonary vein tissue preparations were monitored by contractile force or membrane potential measurement. In quiescent preparations, application of noradrenaline induced an automatic activity. The firing frequency was reduced by prazosin or atenolol. Methoxamine induced an automatic activity of low frequency, which was accelerated by further application of isoproterenol...

Heart failure treatment can count on several drugs, all providing an improvement in outcome, but that cannot be realistically used all together in the same patient. It would be useful to have a tool that allows arranging the most appropriate therapy cocktail in each patient. The aim of this review is to show the main differences in the effects of several drugs on cardiopulmonary function in heart failure patients, both in resting condition and during exercise, and to discuss how these differences can be taken into account when choosing the most appropriate therapeutic protocol...

Shiv Alwera, Ravi Bhushan
Enantioseparation of a few commonly administered racemic β-adrenolytics (namely, carvedilol, betaxolol, salbutamol and bisoprolol) has been achieved using a water micellar mobile phase containing surfactants (sodium dodecyl sulphate and Brij-35) without organic solvents as a new approach in RP-HPLC. Two chiral derivatizing reagents based on enantiomerically pure (S)-(-)-levofloxacin were synthesized using N-hydroxysuccinimide and N-hydroxybenzotriazole as the activation auxiliaries. Diastereomeric derivatives of the chosen β-adrenolytics were synthesized under microwave irradiation in a very short reaction time...

Over the years, thanks to the addition of new generation systemic agents, as well as the use of more advanced and precise radiotherapy techniques, it was able to obtain a high curability rate for breast cancer. Anthracyclines play a key role in the treatment of breast disease, with a well-known benefit on disease-free survival of patients with positive nodal status. Trastuzumab have shown a significant outcome advantage after 1-year administration in case of HER2-positive disease. Unfortunately, significant increase in cardiotoxicity has been observed after anthracyclines and trastuzumab therapies...

AIM: Patient-reported outcomes such as health-related quality of life (HRQoL) are main treatment goals for heart failure (HF) and therefore endpoints in multinational therapy trials. However, little is known about country-specific differences in HRQoL and in treatment-associated HRQoL improvement. The present work sought to examine those questions. METHODS AND RESULTS: We analysed data from the Cardiac Insufficiency Bisoprolol Study in Elderly (CIBIS-ELD) trial, in which patients from central and south-eastern Europe completed the HRQoL questionnaire SF-36 at baseline and the end of a 12-week beta-blocker up-titration (follow-up)...
