Time Change and Acute Myocardial Infarction

In Sweden, acute myocardial infarctions (AMIs) spike noticeably just after daylight savings time (DST) and drop on the Monday after the switch to standard time in autumn. Is the same true in the U.S.? Researchers at Beaumont Hospital in Royal Oak and Oakland University William Beaumont School of Medicine in Rochester, both in Michigan, conducted a retrospective study of all AMIs (935) the week after DST and after the autumn switch between October 2006 and April 2012.
