A new study the 'Journal of the American College of Cardiology' revealed that anger-induced electrical changes in the heart could lead to cardiac arrests in people, mainly in those with implantable cardioverter-defibrillators.In their study, the researchers analysed 62 patients with who had coronary artery disease who underwent monitoring during a mental stress test.
Rachel Lampert of Yale University, who led the study said that it's an important study because 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.
Lampert and her team sought to discover whether T-wave alternans (TWA), which monitor electrical instability in the heart induced by anger, would predict future ventricular arrhythmias. The team found that those in the group with more anger-induced electrical instability were more likely to experience arrhythmias one year after the study than those in the control group.
The mental stress test, conducted in a laboratory setting shortly after ICD implantation (about three months), asked patients to recall a recent situation in which they were angry or aggravated.
so beware of doubling up in fury against someone who said or did something to offend you on the road or at a party or at a public place.
