Having a hot temper may increase your risk of having a heart attack or stroke, according to researchers.
Rage often precedes an attack and may be the trigger, say the US researchers who trawled medical literature.
They identified a dangerous period of about two hours following an outburst when people were at heightened risk.
But they say more work is needed to understand the link and find out if stress-busting strategies could avoid such complications.
People who have existing risk factors, such as a history of heart disease, are particularly susceptible, they told the European Heart Journal.
In the two hours immediately after an angry outburst, risk of a heart attack increased nearly five-fold and risk of stroke increased more than three-fold, the data from nine studies and involving thousands of people suggests.
The Harvard School of Public Health researchers say, at a population level, the risk with a single outburst of anger is relatively low – one extra heart attack per 10,000 people per year could be expected among people with low cardiovascular risk who were angry only once a month, increasing to an extra four per 10,000 people with a high cardiovascular risk.
But the risk is cumulative, meaning temper-prone individuals will be at higher risk still.
Five episodes of anger a day would result in around 158 extra heart attacks per 10,000 people with a low cardiovascular risk per year, increasing to about 657 extra heart attacks per 10,000 among those with a high cardiovascular risk, Dr Elizabeth Mostofsky and colleagues calculate.
