Abstract

Abstract: Objective: The purpose of this study was to investigate the 10-year impact of Hurricane Katrina on the incidence of acute myocardial infarction (AMI) along with contributing risk factors and any alteration in chronobiology of AMI. Methods: A single-center, retrospective, comparison study of AMI incidence was performed at Tulane University Health Sciences Center from 2 years before Hurricane Katrina to 10 years after Hurricane Katrina. A 6-year, pre-Katrina and 10-year, post-Katrina cohort were also compared according to pre-specified demographic, clinical, and chronobiological data. Results: AMI incidence increased from 0.7% (150/21, 079) to 2.8% (2, 341/84, 751) post-Katrina ( P <0.001). The post-Katrina cohort had higher rates of coronary artery disease (36.4% vs. 47.9%, P =0.01), diabetes mellitus (31.3% vs. 39.9%, P =0.04), hyperlipidemia (45.4% vs. 59.3%, P =0.005), smoking (34.4% vs. 53.8%, P <0.001), drug abuse (10.2% vs. 15.4%, P =0.02), psychiatric illness (6.7% vs. 14.9%, P <0.001), medication non-adherence (7.3% vs. 15.3%, P <0.001), and lack of employment (7.2% vs. 16.4%, P <0.001). The post-Katrina group had increased rates of AMI during nights (29.8% vs. 47.8%, P <0.001) and weekends (16.1% vs. 29.1%, P <0.001). Conclusions: Even 10 years after the storm, Hurricane Katrina continues to be associated with increased incidence of AMI, higher prevalence of traditional cardiovascular and psychosocial risk factors, and an altered chronobiology of AMI toward nights and weekends.
