Newswise New Brunswick, NJ -- Heart attacks and strokes are more likely to occur during extreme weather and natural disasters such as earthquakes and floods. Researchers at the Cardiovascular Institute of New Jersey at Rutgers Robert Wood Johnson Medical School have found evidence that Hurricane Sandy, commonly referred to as a superstorm, had a significant effect on cardiovascular events, including myocardial infarction (heart attack) and stroke, in the high-impact areas of New Jersey two weeks following the 2012 storm. The study, led by Joel N. Swerdel, MS, MPH, an epidemiologist at the Cardiovascular Institute and the Rutgers School of Public Health, was published today in the Journal of the American Heart Association (doi: 10.1161/JAHA.114.001354).

Utilizing the Myocardial Infarction Data Acquisition System (MIDAS), the researchers examined changes in the incidence of and mortality from myocardial infarctions and strokes from 2007 to 2012 for two weeks prior to and two weeks after October 29, the date of Hurricane Sandy. MIDAS is an administrative database containing hospital records of all patients discharged from non-federal hospitals in New Jersey with a cardiovascular disease diagnosis or invasive cardiovascular procedure.

In the two weeks following Hurricane Sandy, the researchers found that in the eight counties determined to be high-impact areas, there was a 22 percent increase in heart attacks as compared with the same time period in the previous five years. In the low impact areas (the remaining 13 counties), the increase was less than one percent. 30-day mortality from heart attacks also increased by 31 percent in the high-impact area.

We estimate that there were 69 more deaths from myocardial infarction during the two weeks following Sandy than would have been expected. This is a significant increase over typical non-emergency periods, said Swerdel. Our hope is that the research may be used by the medical community, particularly emergency medical services, to prepare for the change in volume and severity of health incidents during extreme weather events.

In regard to stroke, the investigators found an increase of 7 percent compared to the same time period in the prior five years in areas of the state impacted the most. There was no change in the incidence of stroke in low-impact areas. There also was no change in the rate of 30-day mortality due to stroke in either the high- or low-impact areas.

Hurricane Sandy had unprecedented environmental, financial and health consequences on New Jersey and its residents, all factors that can increase the risk of cardiovascular events, said John B. Kostis, MD, director of the Cardiovascular Institute of New Jersey and associate dean for cardiovascular research at Rutgers Robert Wood Johnson Medical School. Increased stress and physical activity, dehydration and a decreased attention or ability to manage ones own medical needs probably caused cardiovascular events during natural disasters or extreme weather. Also, the disruption of communication services, power outages, gas shortages, and road closures, also were contributing factors to efficiently obtaining medical care.

The research was funded in part by The Robert Wood Johnson Foundation and the Cardiovascular Institute of New Jersey at Rutgers Robert Wood Johnson Medical School.
