Computed Tomography-Derived Bronchial Wall Indices in Cats with Clinical and Serological Features Compatible with Heartworm-Associated Respiratory Disease.

Clinical evidence update from Animals : an open access journal from MDPI

Clinical Context

Peer-reviewed veterinary literature continues to shape everyday decision-making for feline patients, especially when new evidence clarifies diagnosis, treatment selection, monitoring, or clinical outcomes.

What the Study Evaluated

A study published in Animals : an open access journal from MDPI in 2026 evaluated computed Tomography-Derived Bronchial Wall Indices in Cats with Clinical and Serological Features Compatible with Heartworm-Associated Respiratory Disease..

Key Findings

Heartworm-Associated Respiratory Disease (HARD) is an early manifestation of feline dirofilariosis caused by immature Dirofilaria immitis stages reaching the lungs and inducing marked inflammatory airway lesions. This study quantified computed tomography (CT)-derived bronchial wall remodeling in cats with clinical and serological features compatible with HARD using the bronchial wall-to-bronchus (BW/B) and bronchial wall-to-pulmonary artery (BW/A) ratios. Twenty-seven client-owned cats were prospectively included: 19 cats with lower-airway clinical signs and D. immitis antibody seropositivity, considered compatible with HARD, and 8...

Why It Matters for Veterinary Professionals

For veterinary professionals, the practical value of this work lies in how the findings may support more structured clinical assessment, clearer monitoring, and more informed decisions for feline patients.

Practical Interpretation

The results should be interpreted in the context of the study design, population, inclusion criteria, and clinical setting. Application in practice should consider patient-specific risk factors, available diagnostics, local standards of care, and clinician judgment.

Clinical Takeaway

Overall, the study adds useful evidence for clinicians seeking to align daily practice with current veterinary research while maintaining a balanced, case-by-case approach.
