Physical Activity Reduces Risk of Second Heart Attack
Physical activity after a first heart attack reduces the chances of a recurrence, according to a recent survey conducted by the University of Texas - Houston Health Science Center.
More than 400 Texans, aged 25 to 74, who survived at least four weeks after a first heart attack, were interviewed. Half were Mexican American, half were non-Hispanic white, and about one third were women.
Those who increased their activity after their first heart attack had a 78 percent lower risk of a second heart attack, and an 89 percent lower risk of death from all causes, than those who remained sedentary.
Those who maintained their level of activity after their first heart attack had a 60 percent lower risk of a second heart attack, and a 79 percent lower risk of death from all causes, than those who remained sedentary.
Those who decreased their activity had the same risk of a second heart attack as those who remained sedentary, but a 51 percent lower risk of death from all causes, possibly due to a protective effect of earlier activity.
Results were similar regardless of other factors which could affect the risk of a second heart attack: age, sex, ethnicity, severity of the first heart attack, high blood pressure, high cholesterol, diabetes, smoking and a family history of heart disease.
