Abstract
BACKGROUND: Asthma has been associated with the development and progression of various cardiovascular diseases but its relationship with degenerative valvular heart disease (VHD) remains unclear. This study investigated the association between asthma and incident degenerative VHD, including aortic stenosis (AS), aortic regurgitation (AR), mitral regurgitation (MR) and pulmonary regurgitation (PR).</p>
METHODS: We analysed 483 735 participants from the UK Biobank (median age 56.5 years; 45.2% male) who were free of VHD at baseline. Asthma status was self-reported at recruitment. Incident VHD was ascertained through hospital admission and mortality records using International Classification of Diseases, Tenth Revision codes. Cox proportional hazards models were used to estimate HRs and 95% CIs for each VHD subtype, adjusting for demographic, lifestyle and clinical covariates. Sensitivity analyses accounted for asthma medications, duration of asthma and competing risks.</p>
RESULTS: Over a median follow-up of 13.8 years, 5388 participants developed AS, 2650 AR, 6088 MR and 821 PR. Asthma was associated with increased risk of AS (HR 1.31; 95% CI 1.21 to 1.41), AR (HR 1.24; 95% CI 1.11 to 1.39), MR (HR 1.19; 95% CI 1.10 to 1.28) and PR (HR 1.34; 95% CI 1.10 to 1.62). The association with AR was attenuated after adjusting for asthma medications (HR 1.12; 95% CI 0.97 to 1.30). Results were robust across multiple sensitivity analyses, including adjustment for asthma duration and exclusion of participants with pre-existing cardiovascular disease.</p>
CONCLUSIONS: Asthma is independently associated with a modestly increased risk of several degenerative VHDs, particularly aortic and mitral valve diseases. These findings suggest a potential shared inflammatory pathway and highlight the need for heightened cardiovascular surveillance in individuals with asthma.</p>
