Medical Information about Heart Attacks
Why watch sports on television increases the occurrence of heart attacks, one study found that games that are much stress raise blood pressure among those who have already suffered a heart attack
Chinese researchers report that a lower blood flow to the heart may help explain why men who have suffered a heart attack are at greater risk of another while watching exciting sports events.
The study involved 38 men who survived a heart attack that saw the Olympic Games competitions and other live entertainment programs on television. While men were the programs, we evaluated the blood flow in the coronary artery to the heart through analysis of ST segment through a continuous 12-lead electrocardiography, blood pressure monitoring and heart rate measures.
In general, the flow of blood to the heart was stable. But when men watched an exciting sporting event, increased blood pressure, reduced the heart rate variability and increased platelet aggregation (the basic element of clots). All these factors raise the risk of heart attack.
The study was presented Monday at the annual meeting of the American Heart Association in Orlando, Florida.
