Study Shows Air Pollution Exposure Linked to Heart Damage
A recent cardiac MRI study found a connection between exposure to air pollution and an increase in diffuse myocardial fibrosis. The research, published in Radiology, analyzed data from 694 patients and highlighted the impact of fine particulate matter on heart health. The study emphasizes the need to reduce long-term air pollution exposure to protect vulnerable individuals.
Air pollution exposure can contribute to diffuse myocardial fibrosis, as per a new study using cardiac MRI. The study analyzed data from 694 patients, including those with dilated cardiomyopathy (DCM) and normal cardiac MRI. Results showed that higher exposure to fine particulate air pollution was linked to increased myocardial fibrosis. The study emphasized the need to reduce air pollution exposure, especially for vulnerable patients.
Key findings included a 30% higher native T1 z score in DCM patients for each 1 µg/m3 increase in PM 2.5 exposure, and a 27% higher score in individuals with normal cardiac MRI. The study also found associations between pollution exposure and structural heart changes, particularly in women, individuals with hypertension, and smokers.
According to the study authors, the results highlight the cardiovascular risks associated with air pollution exposure, providing new evidence on how fine particulate matter pollution can increase cardiovascular risk by inducing myocardial fibrosis.
