Heat-induced heart attack risk on the rise: Study

Press Trust of India  |  Berlin 

There has been an increase in heat-induced between 2001 and 2014, a study analysing data over a period of 28 years has found.

The study, published in the European Heart Journal, looked at more than 27,000 patients between 1987 and 2014.

The average age of the patients studied was around 63 and 73 per cent were men. About 13,000 ended in the death of the patient.

The individual were compared with meteorological data on the day of the attack and adjusted for a range of additional factors, such as the day of the week and socioeconomic status.

"Over a period of 28 years, we found that there has been an increase in heat-induced in recent years," said Kai Chen, a at Helmholtz Zentrum Munchen in

The researchers compared data from 1987 to 2000 with data from 2001 to 2014.

"Our analysis showed that, over the last few years, the of with increasing average daily temperature has risen compared to the previous investigation period," Chen said in a statement.

Individuals with or hyperlipidaemia -- a condition in which there are high levels of fat particles (lipids) in the blood -- were particularly at risk over the latter period.

The researchers suspect that this is partly a result of global warming, but that it is also a consequence of an increase in risk factors such as and hyperlipidaemia, which have made the population more susceptible to heat.

"Our study suggests that greater consideration should be given to high temperatures as a potential trigger for -- especially in view of climate change," said

"Extreme weather events, like the 2018 heat waves in Europe, could in future result in an increase in cardiovascular disease," Schneider said.

"Our analysis suggests a lower risk in the future, but this lower risk was not significant and very cold days will continue to represent a potential trigger for heart attacks," he said.

To what extent increases in will be counterbalanced by a decrease in is not yet clear, researchers said.

The team is currently performing extrapolations aimed at modelling this change in risk both in scenarios where the world meets the Paris Agreement target to restrict average temperature increase between 1.5 degrees Celsius and 2 degrees Celsius and in scenarios where these targets are missed.
