Background:
Atopic disease has been associated with immune dysregulation and chronic inflammation, but current practice guideline recommendations do not include the evaluation of inflammatory outcomes among patients with asthma and allergic rhinitis (AR).
Objective:
This study investigates the relationship between asthma, AR, and cardiovascular disease (CVD) using data from the U.S. National Health Interview Survey (NHIS) between 1999 and 2018.
Methods:
We used data from adults in the NHIS (n = 603,140, representing a population of 225,483,286). Exposures were physician-diagnosed asthma (lifetime/past-year) and AR (past-year). Outcomes were physician-diagnosed heart disease: coronary heart disease (CHD), angina, heart attack, and nonspecific "heart-condition" (all lifetime). We used survey-weighted descriptive analysis and logistic regression adjusting for demographic and socioeconomic factors.
Results:
A total of 11.44% reported at least 1 heart condition, with CHD the most prevalent (4.27%) across 20 years of pooled data. Asthma and AR were associated with higher CVD in all bivariate analyses. Specifically, lifetime asthma was associated with increased odds of CHD, (odds ratio [OR] 1.36; 95% confidence interval [95% CI] 1.29-1.42), with stronger effects observed for a past-year asthma attack (OR 1.66; 95% CI 1.55-1.80). The strongest effect of all was observed in those with a past-year asthma attack having increased odds of angina (OR 2.42; 95% CI 2.24-2.63). Allergic rhinitis was independently associated with increased odds of CHD (OR 1.25; 95% CI 1.18-1.28).
Conclusions:
Asthma and AR are risk factors for all types of CVD in this nationally representative study covering a 2-decade period in the United States. Clinicians should consider screening patients with severe and/or uncontrolled asthma and AR early for CVD, particularly angina and CHD. Future studies are warranted to explore the immunological milieu in these patients and identify therapeutic targets.

Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
