Allergies Linked to Increased Cardiovascular Risk
A national US health survey has revealed that adults with allergies are at an increased risk of hypertension and coronary heart disease, with the biggest risk increase seen in Black male adults. The study is presented at ACC Asia 2022 Together with the Korean Society of Cardiology Spring Conference.
“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,” said Yang Guo, PhD, the study’s lead author.
An association between allergic disorders and cardiovascular disease was detected in prior research, findings which remained controversial, Dr Guo explained. The present study sought to determine whether an increased cardiovascular risk exists in adults with allergic disorders.
The study used 2012 data from the National Health Interview Survey (NHIS), a cross-sectional survey of the US population. In the allergic group were adults with at least one allergic disorder, including asthma, respiratory allergy, digestive allergy, skin allergy and other allergy. The study included a total of 34 417 adults, over half of whom were women, average age 48.5 years. The allergic group included 10 045 adults. The researchers adjusted for age, sex, race, smoking, alcohol drinking and body mass index; they also examined subgroups stratified by demographic factors.
Having a history of allergic disorders was found to be associated with increased risk of developing hypertension and coronary heart disease. Further analysis showed that individuals with a history of allergic disorders between ages 18 and 57 had a higher risk of hypertension. An increased risk of coronary heart disease was seen in male Black/African American participants between ages 39-57. Asthma was the largest contributor of risk of hypertension and coronary heart disease.
Dr Guo said that to confirmed these findings, large cohort studies with long-term follow-up are required. Discovering the underlying mechanism could also help with management.
