Harvard researchers who analyzed decades of evidence on links between anger and cardiovascular events, concluded that in the 2 hours following an outburst of anger, there is a higher risk of heart attack, stroke or other cardiovascular event.

The systematic review and meta-analysis – thought to be the first to examine links between anger and cardiovascular outcomes – is published in the European Heart Journal.

First author Dr. Elizabeth Mostofsky and colleagues found that – compared with when they are not angry – a person’s risk of heart attack rises nearly five-fold, and the risk of stroke more than three-fold, in the 2 hours following an outburst of anger. Their risk of abnormal heartbeat or ventricular arrhythmia also goes up.

The absolute risk of heart attack, stroke or arrhythmia increased in people who already had a previous history of heart problems, and it also increased the more frequently they were angry.
