Effect of Hurricane Katrina on incidence of acute myocardial infarction in New Orleans three years after the storm.

To detect a long-term increase in the incidence of acute myocardial infarction (AMI) after Hurricane Katrina and to investigate the pertinent contributing factors, we conducted a single-center retrospective cohort observational study. The patients admitted with AMI to Tulane University Hospital in the 2 years before Katrina and the 3 years after the hospital reopened were identified from the hospital medical records. The pre- and post-Katrina groups were compared for prespecified demographic and clinical data.
