Pollution impact on CVD still up in the air: study
THE study, which drew on three national UK databases covering more than one million CV events, included some puzzling discrepancies, it said.
While the research found an association between particulate matter (PM2.5) and deaths from atrial fibrillation and pulmonary embolism, there was no association with hospital admissions.
The study also found a link between nitrogen dioxide and hospitalisation for heart failure and non-ST elevation MI, but no clear evidence for other pollutants or for stroke or other MI risk, contrary to some previous research.
