Commencement of cardioselective beta-blockers during hospitalisation for acute exacerbations of chronic obstructive pulmonary disease

Role of β-blockers in the cardiovascular disease continuum: a collaborative Delphi survey-based consensus from Asia-Pacific

OBJECTIVE

This Delphi method of consensus was designed to develop scientific statements for β-blockers in the continuum of cardiovascular diseases with a special focus on the role of bisoprolol.

METHODS

Eleven experienced cardiologists from across the Asia-Pacific countries participated in two rounds of the survey. In the first round, experts were asked to rate agreement/disagreement with 35 statements across seven domains regarding the use of β-blockers for treating hypertension, heart failure, coronary artery diseases, co-morbidities, as well as their safety profile, usage pattern, and pharmacokinetic variability. A consensus for a statement could be reached with >70% agreement.

RESULTS

Except for seven statements, all attained consensus in the first round. In the second round that was conducted virtually, the experts re-appraised their ratings for the seven statements along with a critical appraisal of two additional statements that were suggested by experts in the preceding round. At the end of the second round, the final version included 36 statements (34 original statements, two statements suggested by experts, and the omission of one statement that did not attain consensus). The final version of statements in the second round was disseminated among experts for their approval followed by manuscript development.

CONCLUSION

Attainment of consensus for almost all statements reconfirms the clinical benefits of β-blockers, particularly β1-selective blockers for the entire spectrum of cardiovascular diseases.

Management of Chronic Obstructive Pulmonary Disease (COPD) Exacerbations in Hospitalized Patients From Admission to Discharge: A Comprehensive Review of Therapeutic Interventions

Chronic obstructive pulmonary disease (COPD) is a common and debilitating condition that often necessitates hospitalization for exacerbations. Since COPD exacerbations can cause significant morbidity and mortality, managing them is crucial for patient care. Effective management of COPD exacerbations is essential to prevent complications, as COPD exacerbations are associated with increased healthcare costs and decreased quality of life. This review aims to comprehensively discuss the management of COPD exacerbations, covering various pharmacologic and non-pharmacologic strategies. These include inhaled bronchodilators, systemic steroids, antibiotics, invasive and non-invasive ventilation, oxygen therapy, smoking cessation, immunization with pneumococcal vaccine, inhalers at discharge, pulmonary rehabilitation, long-term oxygen therapy (LTOT), ambulatory oxygen therapy, short-burst oxygen therapy, extracorporeal membrane oxygenation (ECMO), lung volume reduction surgery (LVRS), endobronchial procedures, and lung transplant. It is drawn upon various sources, including clinical studies, systemic reviews, and observational studies, to provide a comprehensive overview of current practices and identify areas for future research and innovation in managing COPD exacerbations. Addressing these areas of interest can improve patient outcomes and quality of life.

Beta-blockers in chronic obstructive pulmonary disease: the good, the bad and the ugly

PURPOSE OF REVIEW

Several observational studies have suggested that β-blockers, especially cardioselective ones, are well tolerated and associated with a lower risk of acute exacerbations and death in patients with chronic obstructive pulmonary disease (COPD). However, there are dissenting studies. This review provides an update on the use of β-blockers in COPD, focusing on results of recent prospective studies and randomized controlled trials.

RECENT FINDINGS

In totality, cohort studies indicate that β-blockers are generally well tolerated and effective in COPD patients who also have a clear cardiovascular indication for these medications. Although β-blockers on average reduce lung function acutely in COPD patients, the absolute decrease is relatively small, especially if cardioselective β-blockers are used. The results of two large randomized controlled trials suggest that β-blocker use does not reduce the therapeutic benefits of inhaled bronchodilators in COPD patients. The use of β-blockers in COPD patients, who do not have overt cardiovascular disease, does not prevent COPD exacerbations and may paradoxically increase the risk of COPD-related hospitalization and mortality.

SUMMARY

The use of β-blockers is generally well tolerated and effective in COPD patients, who also have a clear cardiovascular indication for these drugs. However, they should not be used in patients who do not have overt cardiovascular disease as β-blockers can reduce lung function, worsen health status and increase the risk of COPD-related hospitalization.

Beta-blockers in COPD: A systematic review based on recent research

Chronic obstructive pulmonary disease (COPD) with cardiovascular complications is very common. Due to fear of exacerbating airway spasm, β-blockers are rarely used in such patients. Many observational studies suggest that β-blockers can reduce the disease progression and the risk of mortality in patients with COPD, but lack of confirmation from randomized controlled trials. This article reviews the application of β-blockers in patients with COPD based on the results of the latest published randomized controlled trials.

Atrial arrhythmias in chronic lung disease-associated pulmonary hypertension

Atrial arrhythmias are common during episodes of acute respiratory failure in patients with chronic lung disease-associated pulmonary hypertension. Expert opinion suggests that management of atrial arrhythmias in patients with pulmonary hypertension should aim to restore sinus rhythm. This is clinically challenging in pulmonary hypertension patients with coexisting chronic lung disease, as there is controversy on the use of rhythm control agents; generally, in regard to either their pulmonary toxicity profile or the lack of evidence supporting their use. Rate control methods are largely focused on the use of beta blockers and calcium channel blockers. Concerns regarding their use involve their negative inotropic properties in cor pulmonale, the risk of bronchospasm associated with beta blockers, and the potential for ventilation/perfusion mismatching associated with calcium channel blockers. While digoxin has been associated with promising outcomes during acute right ventricular failure, there is limited evidence to suggest its routine use. Electrical cardioversion is associated with a high failure rate and it frequently requires multiple attempts. Radiofrequency catheter ablation is a more definitive approach, but concerns surrounding mechanical ventilation and sedation limit its applicability in decompensated pulmonary hypertension. Individual approaches are needed to address atrial arrhythmia management during acute episodes of respiratory failure.
