Single-dose administration of beta-adrenoceptor agonists produces bronchodilation and inhibits airway hyperresponsiveness (AHR), and is the standard treatment for the acute relief of asthma. However, chronic repetitive administration of beta-adrenoceptor agonists may increase AHR, airway inflammation, and risk of death. Based upon the paradigm shift that occurred with the use of beta-blockers i...

Major complications associated with cardiac surgery are still common and carry great prognostic significance. β-Blockers, statins, antiplatelets, and renin-angiotensin system (RAS) blockers are current medical interventions to prevent cardiovascular complications in cardiac surgery. Renin-angiotensin system blockers include angiotensin-converting enzyme inhibitors, angiotensin II receptor block...

Abstract Background In heart failure with mildly reduced ejection fraction (HFmrEF) European guidelines recommend the use of antineurohormonal therapies a low level evidence (IIb C) based on data from subgroup and post-hoc analyses randomized clinical trials (RCTs). Data large unselected real-world HFmrEF populations are lacking. Purpose To assess association between renin-angiotensin system in...

Inaccurate self-reported data on medication exposure lead to less reliable study findings. From 2013 to 2015, we assessed the validity of information on medication use collected via a mailed medication inventory among 223 Women's Health Initiative participants who were members of a health-care delivery system. Self-reported information on medication use was compared with pharmacy records for st...

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 ...

INTRODUCTION Oral beta-blockers improve the prognosis of patients with acute myocardial infarction, while atrial fibrillation worsens the prognosis of this population. The reduction of atrial fibrillation incidence in patients treated with beta-blockers could at least in part explain the benefits of this drug. OBJECTIVE To investigate the effect of beta-blockers on the incidence of atrial fib...

Hypertensive crises (HCs) are common occurrences and can result in immediate or delayed organ damage. Given the complex pathophysiological process associated with HCs, selecting appropriate treatment be a challenge. The goal of this report is to provide nurse practitioners an up-to-date evidence-based mnemonic tool help effectively manage HCs. Using alphabetized provides quick recall into optio...

OBJECTIVE β-adrenergic antagonists (β-blockers) are often used to attenuate the hyperadrenergic symptoms of Graves' disease (GD), including palpitation. Although β-blockers reduce the heart rate, cardiac output and oxygen consumption, no firm evidence exists regarding the effects of combined therapy with β-blockers and anti-thyroid drugs. The objective is to elucidate the effects of β-blockers ...

Combination therapy of hypertension with separate agents or a fixed-dose combination pill offers the potential to lower blood pressure more quickly, obtain target blood pressure, and decrease adverse effects. Antihypertensive agents from different classes may offset adverse reactions from each other, such as a diuretic decreasing edema occurring secondary to treatment with a calcium channel blo...
