Pulmonary hypertension (PH) is a chronic, progressive debilitating disease and associated with poor prognosis despite the novel numerous treatment options. Beta-blockers constitute a cornerstone in left heart failure treatment; however, we still don't know the role of beta-blockers on PH and they are considered relatively contraindicated in patients with PH because of the possible negative effe...
objective: the aim of this study was to assess and compare the effect of two neurofeedback protocols (smr/theta and beta/theta) on adhd symptoms, selective attention and eeg (electroencephalogram) parameters in children with adhd. method: the sample consisted of 16 children (9-15 year old: 13 boys; 3 girls) with adhd-combined type (adhd-c). all of children used methylphenidate (mph) during the ...
Background and Aim: High blood pressure is a common cardiovascular disease. Most cardiovascular medications have adverse oral side effects. This study aimed to determine the prevalence of oral manifestations associated with the intake of anti-hypertensive medications. Materials and Methods: This cross-sectional analytical study examined 142 patients with a history of hypertension referred to D...
The effects on diabetic control of the relative cardioselective beta-blocker metoprolol and the non-selective drug propranolol were compared in 20 hypertensive diabetic patients receiving diet alone or diet and oral hypoglycaemic agents. Each drug was given for one month in a double-blind, cross-over study. Fasting, noon, and mid-afternoon blood sugar concentrations rose by 1.0-1.5 mmol/l (18-2...
AIMS To evaluate the effect of beta-blockers in children with long QT syndrome (LQTS) we reviewed the outcome of 122 patients (pts). METHODS LQTS was diagnosed in 24 neonates and in 98 pts aged 0.5-15 years. Diagnosis was made because of syncope in 51 pts, bradycardia in 10 neonates and family history in 61 pts. The longest QTc ranged from 400 to 700 ms. Thirteen pts had 2:1 atrioventricular ...
OBJECTIVES Beta blockers reduce mortality in heart failure (HF). However, it is not clear whether they should be temporarily withdrawn during acute HF. DESIGN Analysis of prospectively collected data. SETTING The Gulf aCute heArt failuRe rEgistry is a prospective multicentre study of patients hospitalised with acute HF in seven Middle Eastern countries. PARTICIPANTS 5005 patients with acu...
BACKGROUND Peculiar aspects of Chagas cardiomyopathy raise concerns about efficacy and safety of sympathetic blockade. We studied the influence of beta-blockers in patients with Chagas cardiomyopathy. METHODS AND RESULTS We examined REMADHE trial and grouped patients according to etiology (Chagas versus non-Chagas) and beta-blocker therapy. Primary end point was all-cause mortality or heart t...
AIMS The impact on mortality outcomes of beta-blockers and calcium blockers in post-myocardial infarction (MI) has been suggested to be related to resting heart rate (HR) reduction. A meta-regression of randomized clinical trials was carried out to assess this relationship using weighted meta-regression of logarithm of odds ratio against absolute HR reduction. METHODS AND RESULTS Twenty-five ...
Anxiety disorders are the most prominent mental illness in the United States, affecting 18 percent of the population. Aversive memories, such as traumatic events, are associated with unconditioned stimuli. Few studies have shown that cardiovascular dysfunctions can be associated with aversive contexts or cues. However, preliminary results demonstrate that the beta-adrenergic agonist isoprenalin...
