Being ‘sick at heart’ is a common complaint in romantic novels, but can intense emotional pain actually damage your heart?
The answer is yes, cardiologists say, and sometimes it can be deadly – although thankfully this seems to be rare.
One example that made headlines around the world recently was Adelaide grandfather NK Paliwal, who had a heart attack and died upon learning his family had been killed in a road crash in India.
And it is known that spouses or partners who lose a loved one are at increased risk of death from heart attacks in the days, weeks and months afterwards.
It is thought the impact of stress hormones on heart rate, blood pressure, and blood clotting may be one reason for these associations.
Broken heart syndrome
But experts now wonder if at least some of the deaths linked with high emotions might actually be missed cases of a different heart condition that has been recognised in Australia for only about 10 years.
‘Broken heart syndrome’ or stress cardiomyopathy happens when a surge in the stress hormone adrenaline causes inflammation of the heart. It also goes by the name Takotsubo cardiomyopathy, because the abnormal shape of the affected heart resembles a traditional Japanese octopus fishing pot.
“You can actually inject adrenaline into someone and cause it… there’s a lot of evidence to suggest that adrenaline is involved,” said Professor John Horowitz, head of cardiology at Adelaide’s Queen Elizabeth Hospital, who researches the syndrome.
Happiness can break your heart too
- Emotional triggers for ‘broken heart syndrome’ don’t have to be negative.
- Around 4 per cent of the emotional jolts that bring the syndrome on are actually joyful events like the birth of a child, or a big win by your team, said researchers who published new findings in the European Heart Journal this week.
- “Perhaps both happy and sad life events, while inherently distinct, share final common pathways in the central nervous system output, which ultimately lead to Takatsubo syndrome,” said one of the authors, Dr Jelena Ghadri, resident cardiologist, at the University Hospital Zurich in Switzerland.
It is thought the overload of stress hormones essentially ‘stuns’ the heart, but exactly how this happens is not understood.
While the symptoms are similar to a heart attack (where an artery leading to the heart is partially or completely blocked), there is no blockage involved.
