NEW YORK, March 17 (UPI) -- Data shows that the Sept. 11, 2001, World Trade Center collapse in New York caused potentially dangerous heart problems to first responders, researchers said.
Dr. Jacqueline Moline of the Mount Sinai School of Medicine in New York, and leader of the World Trade Center Medical Monitoring and Treatment Program, said the study showed responders have impaired diastolic function of both the right and left ventricle, meaning their hearts do not relax normally, which can put them at risk for heart problems such as shortness of breath and heart failure.
The researchers conducted the analyses of 1,236 workers who participated in the program from January 2008 to June 2009.
More than 50 percent of the workers had abnormal relaxation of the left ventricle compared with only 7 percent of people of a similar age in the general population. More than 60 percent had isolated impaired diastolic function in the right ventricle of the heart, which pumps blood to the lungs, the study said.
The findings are being presented at the American College of Cardiology 59th annual scientific session in Atlanta.
