Stress is already known to be one factor that may lead to cardiovascular problems.

Now, new research suggests that anger sets off some electrical changes in the heart, which may result in future rhythm problems.

Arrhythmias occur when the electrical impulses in the heart that coordinate heartbeats malfunction, with the result that the organ beats too quickly, too slowly or irregularly. Over time, these rhythm problems may lead to stroke or congestive heart complications.

Study author Dr. Rachel Lampert suggested that by focusing on teaching people how to control anger and lower stress, the overall incidence of heart problems may be reduced.

“We are beginning to understand how anger and other types of mental stress can trigger potentially lethal ventricular arrhythmias, especially among patients with structural heart abnormalities,” she said.

The study, published in the Journal of the American College of Cardiology, was conducted on patients who had implantable cardioverter-defibrillators – devices that monitor heart rhythms.

Meditation, yoga and massage are among the health resources available to those who are feeling stressed.
