Effect of Hurricane Katrina on Chronobiology at Onset of Acute Myocardial Infarction During the Subsequent Three Years

Background The global burden of cardiovascular mortality is increasing, as is the number of large-scale humanitarian emergencies. The interaction between these phenomena is not well understood. This review aims to clarify the relationship between humanitarian emergencies and cardiovascular morbidity and mortality. Methods With assistance from a research librarian, electronic databases (PubMed, Scopus, CINAHL, Global Health) were searched in January 2014. Findings were supplemented by reviewing citations of included trials. Observational studies reporting the effect of natural disasters and conflict events on cardiovascular morbidity and mortality in adults since 1997 were included. Studies without a comparison group were not included. Double-data extraction was utilized to abstract information on acute coronary syndrome (ACS), acute decompensated heart failure (ADHF), and cardiac death (SCD). Review Manager 5.0 was used to create figures for qualitative synthesis (Version 5.2, Copenhagen Denmark, The Nordic Cochrane Centre). Results The search retrieved 1697 unique records; 24 studies were included (17 studies of natural disasters, 7 studies of conflict). These studies involved 14,583 cardiac events. All studies utilized retrospective designs: 4 were population-based, 15 were single-center, and 5 were multicenter studies. 23 studies utilized historical controls in the primary analysis, and 1 utilized primarily geographical controls. Conflicts are associated with an increase in long-term morbidity from ACS; the short-term effects of conflict vary by study. Natural disasters exhibit heterogeneous effects including increased occurrence of ACS, ADHF, and SCD. Conclusions In certain settings, humanitarian emergencies are associated with increased cardiac morbidity and mortality that may persist for years following the event. Humanitarian aid organizations should consider morbidity from non-communicable disease when planning relief and recuperation projects.

“…4,5 Furthermore, after Hurricane Katrina, the increase in the percentage of admissions for AMI was accompanied by an alteration in the traditional chronobiological pattern of onset of AMI, suggesting possible changes in factors triggering the acute event. 6 Because neither the occurrence nor the chronobiology of AMI presented any sign of returning to pre-Katrina levels in the first 3 years after the storm, the long-lasting effect of Hurricane Katrina is yet to be established. Consequently, the present study was designed to provide a long-term follow-up (4-6 years) on the effects of Hurricane Katrina on the pattern of AMI in New Orleans.…”

“…Previous studies have shown an increase in AMI during the immediate hours to weeks following natural disasters45. However, most studies have been conducted on the long-term effects of extreme weather events, such as Hurricane Katrina, which have been shown to be associated with an increased incidence of ACS occurring for up to six years after the hurricane134647. A single-center study found a 3-fold increase in the proportion of admissions for AMI in the 2 years following Katrina (2.18% vs. 0.71%, p < 0.0001), and also noted that the post-Katrina group had higher rates of unemployment, lack of insurance, medication non-compliance, smoking, and substance abuse13.…”

This study investigated the interaction effects of meteorological factors and air pollutants on the onset of acute coronary syndrome (ACS). Data of ACS patients were obtained from the Taiwan ACS Full Spectrum Registry and comprised 3164 patients with a definite onset date during the period October 2008 and January 2010 at 39 hospitals. Meteorological conditions and air pollutant concentrations at the 39 locations during the 488-day period were obtained. Time-lag Poisson and logistic regression were used to explore their association with ACS incidence. One-day lag atmospheric pressure (AP), humidity, particulate matter (PM2.5, and PM10), and carbon monoxide (CO) all had significant interaction effects with temperature on ACS occurrence. Days on which high temperatures (>26 °C) and low AP (<1009 hPa) occurred the previous day were associated with a greater likelihood of increased incidence of developing ACS. Typhoon Morakot was an example of high temperature with extremely low AP associated with higher ACS incidence than the daily average. Combinations of high concentrations of PM or CO with low temperatures (<21 °C) and high humidity levels with low temperatures were also associated with increased incidence of ACS. Atmospheric pollution and weather factors have synergistic effects on the incidence of ACS.
