Desert dust events may trigger myocardial infarctions
Ryuichi Matsukawa, M.D., Ph.D., from Saiseikai Fukuoka General Hospital in Japan, and colleagues assessed data from AMI-related hospitalization for 3,068 consecutive patients from four AMI centers in Japan. Data were collected for AD from April 2003 to December 2010, and a time-stratified case-crossover design was used to assess the correlation between AD and AMI incidence.
The researchers found that after controlling for ambient temperature and relative humidity, the occurrence of AD events zero to four days before the day of admission correlated significantly with AMI incidence. Specifically, AD occurrence four days before admission correlated significantly with AMI onset.
"In conclusion, we observed an association between AD events and the occurrence of AMI," the authors write. "Exposure to AD may be a trigger of AMI."
