Bronchial Asthma as a Cardiovascular Risk Factor: A Prospective Observational Study

Area of Science:

• Cardiovascular Research
• Pulmonary Medicine
• Inflammation Studies

Background:

• Asthma, a chronic inflammatory condition, is suspected to increase cardiovascular disease (CVD) risk through endothelial dysfunction (ED).
• Limited research exists on the direct association between asthma and CVD risk factors.

Purpose of the Study:

• To investigate the relationship between endothelial dysfunction (ED) and asthma severity.
• To assess ED in relation to eosinophilic inflammation, lung function, and asthma control.

Main Methods:

• Compared 52 young asthmatics with 45 healthy controls.
• Measured microvascular responsiveness using the reactive hyperemia index (RHI) via EndoPAT2000.
• Assessed inflammatory markers: VCAM-1, ADMA, hsCRP, and E-selectin.

Main Results:

• Asthmatics exhibited significantly lower RHI values and higher hsCRP levels compared to controls.
• A decreasing RHI trend and increasing hsCRP and E-selectin levels were observed with increasing asthma severity.
• Higher body mass index (BMI) was noted in asthmatics, particularly in women and those with severe asthma.

Conclusions:

• Asthma is associated with progressing cardiovascular disease (CVD) and worsening endothelial dysfunction (ED).
• The increased CVD risk in young asthmatics is linked to disease severity and inflammation.
• Further research is needed on CVD risk factors and disease control mechanisms in asthma.
