Abstract 17955: Hurricane Katrina and Acute Myocardial Infarction: Ten Years After the Storm
Introduction: We aimed to evaluate the incidence and contributing factors of acute myocardial infarction (AMI) in New Orleans ten years after Hurricane Katrina.
Methods: This is a single-center, retrospective study performed at Tulane University Health Sciences Center involving patients admitted for AMI in the two years before Hurricane Katrina and ten years afterward. The results were validated with chi-square and unpaired student t-tests. The pre-Katrina and post-Katrina cohorts were compared according to pre-specified demographic and clinical data.
Results: In the 10-year post-Katrina period, there were 2,341 admissions for AMI out of a total census of 84,751 (2.8%) compared to 150 admissions out of a census of 21,079 (0.7%) in the 2-year pre-Katrina group (p<0.0001). The post-Katrina group had a higher prevalence of known coronary artery disease (47.9% vs. 30.7%, p<0.0001), diabetes mellitus (39.9% vs. 28.7%, p<0.005), hypertension (80.6% vs. 74%, p<0.05), hyperlipidemia (59.3% vs. 45.0%, p<0.0001), smoking (53.8% vs. 39.3%, p<0.0005), drug abuse (16.4% vs. 6.7%, p<0.005), and psychiatric disease (14.9% vs. 6.7%, p<0.0005). The post-Katrina group was more often prescribed aspirin (50.4% vs. 31.3%, p<0.0001), beta-blockers (47.9% vs. 34.0%, p<0.005), ACE inhibitors or angiotensin receptor blockers (52.9% vs. 36.0%, p<0.0002), and statins (51.7% vs. 28.0%, p<0.0001), but have higher medication non-adherence (16.4% vs. 7.3%, p<0.0001). The post-Katrina patients are also more likely to be unemployed (17.5% vs. 2.0%, p<0.0001), uninsured (12.3% vs. 6.0%, p<0.0001) and not married (61.5% vs. 54.7%, p<0.0001). No significant differences between the two groups were noticed in terms of sex or prior coronary artery bypass grafting.
Conclusion: The incidence of AMI now ten years after Hurricane Katrina continues to be significantly higher with increased prevalence of not only psychosocial and behavioral risk factors but also medical illnesses such as hypertension and diabetes mellitus that were not evident in the initial years after the storm. The economic, social, and psychological disruptions after this massive natural disaster may have had a greater impact on the development of chronic medical diseases than originally realized.
