Cardiac asthma — Clinical Guidelines

Overview

Cardiac asthma, often a misnomer for severe asthma with significant respiratory symptoms mimicking cardiac issues, particularly involves patients experiencing dyspnea, wheezing, and chest tightness without clear evidence of cardiac pathology 10. It highlights the overlap in symptomatology between respiratory and cardiac conditions, necessitating careful differentiation.

Diagnosis

Clinical Presentation: Dyspnea, wheezing, and chest tightness 10.

Exclusion of Cardiac Causes: ECG, echocardiography, and cardiac biomarkers to rule out cardiac etiologies 10.

Pulmonary Function Tests: Essential to confirm obstructive lung disease 10.

Imaging: Chest X-ray or CT to assess for pulmonary involvement 10.

Management

First-Line Treatments:

- Bronchodilators: Short-acting beta-agonists (SABAs) for acute relief, long-acting beta-agonists (LABAs) for maintenance 10. - Inhaled Corticosteroids: For controlling inflammation 10.

Adjunctive Treatments:

- Leukotriene Receptor Antagonists: For additional control in moderate to severe cases 10. - Oxygen Therapy: For hypoxemia 10.

Special Populations

Pregnancy: Limited specific guidance; focus on safe use of inhaled medications and close monitoring 8.

Elderly: Consider comorbidities and adjust treatments accordingly, possibly reducing systemic corticosteroid use due to side effects 10.

Key Recommendations

Thorough Exclusion of Cardiac Causes: Prioritize ECG, echocardiography, and biomarker assessment to differentiate from cardiac conditions (Evidence: Moderate 10).

Utilize Pulmonary Function Tests: Confirm diagnosis of obstructive lung disease (Evidence: Moderate 10).

Tailored Treatment Based on Severity: Initiate with bronchodilators and inhaled corticosteroids, escalate with adjunctive therapies as needed (Evidence: Moderate 10).

Monitor and Adjust in Special Populations: Especially in pregnant women and elderly patients, consider individual risks and benefits (Evidence: Expert opinion 8 10).
