Slight decrease in temperature boosts heart attack risk: study
SENIOR citizens and people with heart conditions should wear layers in the winter and adequately heat their homes, as researchers say in a new study the measures could save lives.
A drop of 1 C in temperature leads to 200 extra heart attacks on a single day, suggests lead researcher Krishnan Bhaskaran of the London School of Hygiene and Tropical Medicine.
"We see it's important that doctors need to remind people of common sense. When temperatures are going down, people need to wear warmer clothing, spend less time outdoors and to properly heat their homes, especially for the elderly who are more at risk," Bhaskaran said.
In one of the largest population-based studies on heart attacks, Bhaskaran and a team of scientists examined more than 84,000 heart attack patients between 2003 and 2006 and compared daily temperatures in England and Wales during that time. Results showed that as temperatures dipped by 1 C, heart attacks increased by two per cent.
Bhaskaran said the two per cent increase may seem minute but the climb translates to 200 extra incidents daily in the U.K., where there are about 146,000 heart attacks per year.
