The effects of earthquakes on ischemic heart disease (IHD) have often been reported. At a population level, this study examined short-term (60-day) and long-term (5-year) hospitalization events for IHD after the 2008 Sichuan earthquake.

We examined the 10-year medical hospitalization records on IHD in the city of Deyang provided by the Urban Employee Basic Health Insurance program.

Evaluation of 19,083 hospitalizations showed a significantly lower proportional number and cost of hospitalizations in the 60 days after the earthquake (P<0.001). Hospitalizations were 27.81% lower than would have been expected in a normal year; costs were 32.53% lower. However, in the 5 years after the earthquake, the age-adjusted annual incidence of hospitalization increased significantly (P<0.001). In the fifth year after the earthquake, it was significantly higher in the extremely hard-hit area than in the hard-hit area (P<0.01).

After the 2008 earthquake, short- and long-term patterns of hospitalization for IHD changed greatly, but in different ways. Our findings suggest that medical resources for IHD should be distributed dynamically over time after an earthquake. (Disaster Med Public Health Preparedness. 2016;10:203–210)

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.

With assistance from a research librarian, electronic databases (PubMed, Scopus, CINAHL, and 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 sudden cardiac death (SCD). Review Manager 5.0 (Version 5.2, The Nordic Cochrane Centre; Copenhagen Denmark,) was used to create figures for qualitative synthesis.

The search retrieved 1,697 unique records; 24 studies were included (17 studies of natural disasters and seven studies of conflict). These studies involved 14,583 cardiac events. All studies utilized retrospective designs: four were population-based, 15 were single-center, and five were multicenter studies. Twenty-three studies utilized historical controls in the primary analysis, and one 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.

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 noncommunicable disease when planning relief and recuperation projects.

This retrospective study included 75 persons with ischemic heart disease who were admitted to the Cardiac policlinic for a control check-up immediately after the suspension of air raids. Two-thirds of them were male (average age 62 ±10). Data were obtained using a specially conceived questionnaire based on recall.

Almost 40% of patients estimated that they were very anxious the week before the attacks began, but the anxiety decreased after the beginning of the air raids. Frequency of anginal pains increased after the start of the air raids, but the difference was not statisticaly significant. The intensity of pains drastically increased in the first week of war. Consequently, the average number of pain killers consumed increased from the week before the attacks to the first week of the attacks, and it reached the highest value the week after the suspension of the attacks (1.39, 1.87, and 3.02 pain pills per week, respectively). The average weekly number of medications was 3.50 in the week prior to the air raids, increased to 5.05 during the first week of air raids, and rose to 6.06 in the week after the suspension.

The adjustment on the psychological level was rapid but physical symptoms increased. This implies that physical adaptation to stress could be slower, or that the stress of the war provoked permanent changes in physical status.
