Cold Weather Boost Heart Attack Risk
Cold weather apparently can increase the risk of heart attack. Based on a research by the London School of Hygiene & Tropical Medicine, when the temperature drops one degree centigrade in a day, raises two percent increase in heart disease in the following weeks.
According to study authors, Krishnan Bhaskaran, with this two percent increase, heart disease patients risk will rise. “Because all people face climate change,” he said. “Elders and those with heart problems are particularly vulnerable to the effects of temperature decrease,” he added.
Based on an analysis of the record of 84,000 hospital patients of heart attack for three years between 2003 to 2006 shows, when the temperature drops, the blood pressure rises, causes blood to be thicker and makes the heart work harder. Bhaskaran emphasize the relationship between rising rates of death with the cold weather is a global phenomenon. “We can not control the weather, but we can be alert,” he said.
He suggested several steps that can be done to minimize the risk of the blood vessel disorders. Which are, wearing warm clothing, keeping house warm and limit the amount of time spent outdoors, especially during cold weather.
“Those who have prescribed drugs such as aspirin to control the risk of heart problems should still take them,” Bhaskaran suggests.
Professor of cardiology at the University of California, Los Angeles, Dr. Gregg C. Fonarow, said these findings should be understood in accordance with the context.
According to him, this study extend previous findings linking the decrease in temperature with increased mortality
However, Fonarow still see the risk of heart attack associated with the temperature is too small compared with the cardiovascular risk associated with smoking, obesity, physical activity, high cholesterol, high blood pressure and other factors. Bhaskaran and his team’s research was published August 10 in the British Medical Journal online edition.
