CHICAGO (AP) - Sex and physical exercise can cause heart attacks in older people often do not practice one or the other as further analysis.
The risk is low, but is an excellent reminder that some people should move gradually change their exercise habits, especially after age 50.
The people who exercise regularly have a much lower risk of heart attacks immediately after a sexual or physical activity, said its author, Dr. Issa Dahabreh, Tufts Medical Center in Boston.
"very bad that someone would think that our research will mean that people should not do physical exercise, "said Dahabreh." Either way, this is the case otherwise. "
The analysis, published Wednesday in the Journal of the American Medical Association, combines the results of 14 studies involving over 6,000 patients.
The study included only people who had had a heart attack or sudden stop due to a heart ailment that body. The study looked at what they did people for an hour or two before suffering a heart attack and compared with the activity of the same person in normal days but no major heart problems.
The study aims to clarify "why heart attacks occur."
physical activity and sex increase the risk of heart attack by a factor of three, according to the analysis of results. Exercise increases the risk of sudden cardiac arrest almost five times. But researchers found no relationship between sex and sudden cardiac arrest, ie, a sudden death from a heart problem.
The risk to any individual is extremely low.
"If you follow 10,000 people for one year and they all decide to increase their physical activity in one hour a week, one would expect two or three more heart attacks," said Dahabreh.
That risk is offset in most cases for the benefit of exercise. In general, the people move, least likely that exercise or sex cause a heart attack.
Most of the patients who participated in the study were very accomplished 50 years or were in the top of the 60's.
Exercise training could be considered for sex, according to Mercedes Carnethon, heart disease researcher at the Feinberg School of Medicine at Northwestern University who was not involved in the investigation.
