People who go through severe anger outbursts have a higher risk of suffering cardiovascular events in the next two hours following an episode, a new study published in the European Heart Journal reveals.
Researchers at Harvard Medical School analyzed data of nine different studies in which anger and cardiovascular events were self-reported over nearly two decades.
The researchers found that those who experienced a severe anger outburst were 4.74 times more likely to suffer from myocardial infarction or acute coronary syndrome in the hours following the outbursts.
"A person with pre-existing heart disease or cardiovascular disease, the absolute risk they are incurring is much greater than (that of) a person without cardiovascular disease or risk factors. If we look at somebody at higher risk for having cardiovascular events, and they get angry multiple times a day, this can lead to 650 extra heart attacks per year out of 10, 000 a year. When we look at a person who is relatively low risk, but if they do have these episodes of anger fairly frequently, we estimate there would be about 150 extra heart attacks out of 10,000 a year", lead researcher Dr Murray A. Mittleman said.
