BACKGROUND Underrepresentation of women in heart failure clinical trials has limited conclusions regarding the effect of various management strategies on survival in women with heart failure and decreased left ventricular ejection fraction (LVEF). METHODS AND RESULTS MERIT-HF (Metoprolol Extended-Release Randomized Intervention Trial in Heart Failure) was a randomized, placebo-controlled stud...

AIMS Atrial fibrillation (AF) affects ∼2% of the total population. In order to prevent AF recurrences, many anti-arrhythmic drugs are currently available, but most of them are burdened by serious side effects and suboptimal efficacy. The aim of the present study was to test efficacy and safety of a combination of flecainide and metoprolol in preventing AF clinical recurrences. METHODS AND RES...

UNLABELLED Heart rate slowing is the beneficial effect after beta-blocker administration in cardiac heart failure and ischemic heart disease. However, bradycardia and another cardiac disturbances after beta-blockers therapy are the most dangerous side effects. Many patients with cardiovascular diseases receiving beta-blockers are recommended to statin therapy, as well. Previous study showed tha...

Endothelial dysfunction which is manifested by the loss of nitric oxide bioavailability, is an increasingly recognized cause of cardiac syndrome X (CSX) and beta blockers are used for the treatment of this syndrome. Thus, the aim of this study was to investigate effects of metoprolol, as a beta blocker, on endothelial function in CSX patients. The study included 25 CSX patients (20 female/ 5 ma...

We used Daphnia magna bioassays to determine the LC(50) and the effects on the heart of the cardioactive drugs ouabain, verapamil, metaproterenol and metoprolol. Distinctions were made between the pharmacological and toxicological effects of these drugs and the adequacy of physicochemical characteristics of its habitat (reconstituted water). Video microscopy and digital image processing were us...

AIMS Contemporary adjuvant treatment for early breast cancer is associated with improved survival but at the cost of increased risk of cardiotoxicity and cardiac dysfunction. We tested the hypothesis that concomitant therapy with the angiotensin receptor blocker candesartan or the β-blocker metoprolol will alleviate the decline in left ventricular ejection fraction (LVEF) associated with adjuva...

BACKGROUND Cardiovascular autonomic neuropathy (CAN) is recognized as a significant health risk, correlating with risk of heart disease, silent myocardial ischemia or sudden cardiac death. Beta-blockers are often prescribed to minimize risk. OBJECTIVES In this second of two articles, the effects on parasympathetic and sympathetic activity of the alpha/beta-adrenergic blocker, Carvedilol, are ...

BACKGROUND AND OBJECTIVES Injection pain after propofol administration is common and may disturb patients' comfort. The aim of this study was to compare effectiveness of intravenous (iv) nitroglycerin, lidocaine and metoprolol applied through the veins on the dorsum of hand or antecubital vein on eliminating propofol injection pain. METHOD There were 147 patients and they were grouped accordi...

OBJECTIVES To compare the effects of dry needling of myofascial trigger points in the neck region to metoprolol in migraine prophylaxis. DESIGN Randomized, group comparative study. patients, investigator and statistician were blinded as to treatment, the therapist was blinded as to results. SETTING Outpatient pain clinic in the northern Copenhagen area. Patients were referred by general pra...
