Scientists from Peking University found adults with a history of allergic disorders have an increased risk of high blood pressure and coronary heart disease, with the highest risk seen in Black male adults.

The research was presented at ACC Asia 2022 Together with the Korean Society of Cardiology Spring Conference and was conducted by Yang Guo et al.

Previous studies reported an association between allergic disorders and heart disease, which remain controversial findings.

The current study aimed to determine whether adults with allergic disorders have increased cardiovascular risk.

In the study, the team used data from the National Health Interview Survey.

The allergic group included adults with at least one allergic disorder, including asthma, respiratory allergy, digestive allergy, skin allergy and other allergy.

Overall, the study included 34,417 adults, over half of whom were women and averaged 48.5 years old. The allergic group included 10,045 adults.

The researchers found a history of allergic disorders was linked to an increased risk of developing high blood pressure and coronary heart disease.

In further analyses, people with a history of allergic disorders between ages 18 and 57 had a higher risk of high blood pressure.

A higher risk of coronary heart disease was seen in study participants who were between ages 39–57, male and Black/African American. Asthma contributed most to the risk of high blood pressure and coronary heart disease.

The team says for patients with allergic disorders, routine evaluation of blood pressure and routine examination for coronary heart disease should be given by clinicians to ensure early treatments are given to those with hypertension or coronary heart disease.
