Association of adult-onset asthma with specific cardiovascular conditions.
ABSTRACT While asthma is known to be associated with cardiovascular disease (CVD), the relation to specific manifestations of CVD has not been previously described. Our objective was to explore the relation of child and adult-onset asthma with specific CVD conditions.
We examined data from 16,943 (projected 178 million) U.S. adults aged 18-90 years old with relevant information on asthma and CVD. The study was a cross-sectional analysis of the National Health and Nutrition Examination Survey 1999-2006. We determined the prevalence of CVD risk factors and likelihood of CVD conditions according to gender and asthma status using multiple logistic regression adjusted for age, gender and other CVD risk factors.
The proportions of subjects with child and adult-onset asthma were 4.8% (n=702) and 3.3% (n=534), respectively. Adult-onset asthma was significantly associated with total CVD (OR=2.07, CI=1.2-3.7), but child-onset asthma was not associated with any CVD conditions. Of the four specific CVD endpoints, adult-onset asthma overall was only associated with coronary heart disease (CHD) (OR=2.26, CI=1.2-4.2) in the total population.
Our data suggests that CHD is the major cardiovascular condition associated with asthma; a prospective study must be done to confirm a causal relationship.

ABSTRACT: PURPOSE OF REVIEW: Asthma is often associated with different comorbidities, mainly gastro-oesophageal reflux disease and allergic rhinitis, but also obesity, depression, diabetes mellitus and cardiovascular disease, which may affect its clinical intensity and severity. The prevalence of these comorbidities varies tremendously between studies. Nevertheless, it imposes a significant reflection on the need to explore the phenomenon in depth. RECENT FINDINGS: Both clinical and basic studies have established that inflammation plays a vital role in the initiation and progression of several comorbidities. However, the role of systemic inflammation in asthma is still unclear. Understanding mechanism(s) that link(s) asthma and its comorbid diseases is essential to design an effective therapeutic approach. SUMMARY: In the future, researchers must identify the weight of any comorbidity in patients with asthma, find the true mechanism(s) that link(s) it to asthma and act on these mechanisms that probably create a vicious circle. Conversely, we do not think it reasonable that the generalization of treatment with a holistic approach might affect the link(s) between asthma and its comorbidities.Current opinion in pulmonary medicine 10/2012; · 3.12 Impact Factor
