Cars and TVs increase the risk of heart attacks

Worldwide studies have shown that moderate physical activity during work and leisure significantly reduces the risk of heart attacks in developed and developing countries. Cars and TVs were associated with an increased risk of heart attacks, especially in countries with low and middle income countries.

The results are mainly from the INTERHEART study, which involved more than 29 thousand people from 262 centres in 52 countries in North and South America, Asia, Europe, the Middle East, Africa and Australia. It is published in the European Heart Journal.

"Until now, few studies paid attention to different aspects of physical activity at work and during free time in connection with the risk of heart attacks," says Professor Claes held, first author of the international INTERHEART study. "Much is already known about the relationship between physical activity and risk of cardiovascular attack, but what this study adds some other factors of social life, among many other things, is a global perspective. Stay in good physical shape throughout life may be one of the easiest, cheapest and most effective ways to avoid a coronary care unit".

The study shows that mild moderate physical activity at work, and any level of physical activity during free time, can reduce the risk of heart attack, independent of other traditional risk factors in men and women of all ages, in most regions of the world and in countries with low, medium or high income. Interestingly, heavy physical labor at work you cannot protect yourself from heart attacks.

"These data extend the importance of physical activity and confirm a consistent protective effect of physical activity in addition to the known advantages of the modification of traditional risk factors such as Smoking and alcoholism. In addition, it was found that car ownership and a TV, which promotes sedentary behavior is associated with a greater risk of heart attacks".

The authors conclude that daily moderate exercise should be encouraged all to prevent heart disease.
