"What we're seeing is over and beyond what can be explained by blood pressure, obesity, cholesterol, age, cigarette smoking, blood sugar levels and other cardiovascular risk factors," said Biing-Jiun Shen, Ph.D., an assistant professor of psychology at the University of Southern California in Los Angeles.
The role of anxiety in hiking heart attack risk also goes beyond the effects of depression, anger, hostility, Type A behavior and other negative emotions."These psychological factors are important in predicting the risk of heart disease, but anxiety is unique," Dr. Shen said."Older men with sustained and pervasive anxiety appear to be at increased risk for a heart attack even after their levels of depression, anger, hostility and Type A behavior are considered."
For the study, Dr. Shen and his colleagues analyzed data from the Normative Aging Study, which was designed to assess medical and psychological changes associated with aging among a group of initially healthy men.Each of the 735 men participating in the new analysis completed psychological testing in 1986 and was in good cardiovascular health at the time.
Although most people think of anxiety as intense worry, Dr. Shen and his colleagues looked much deeper, examining four different measures of anxiety.

"The good thing about anxiety is that it's very treatable," said Dr. Shen."If someone is highly anxious--if they're suffering from panic attacks or social phobia or constant worry--we recommend therapy.Although more research is needed, we hope that by reducing anxiety, we can lower the future risk of heart attack.This is one more reason to seek help."
Dr. Shen said the new research does not address the role of anxiety in provoking heart attacks in women.He and his colleagues are considering such a study in the future.
The full study is published in the January 15, 2008, issue of the Journal of the American College of Cardiology.
Dr. Shen reports no conflicts related to this study, which was supported by a grant from the American Heart Association and an award from the National Alliance for Research on Schizophrenia and Depression.
