Heart failure patients who started an aerobic exercise program reported better quality of life after three months, though the activity only modestly reduced their risk of being hospitalized or dying over two and a half years, researchers have found.
The results appear to resolve the question of whether it is safe for medically stable patients with heart failure to engage in physical activity, since participants in the exercise group were no more likely to suffer an adverse event than those who were not exercising. Patients with heart failure have traditionally been told to rest, but that recommendation is changing in light of evidence that suggests physical activity is beneficial and may even increase survival rates in some patients.
Two studies, to be published Wednesday in The Journal of the American Medical Association, report data from a controlled clinical trial sponsored by the National Heart, Lung and Blood Institute. One analysis found that exercise improved overall well-being, while the other found that it slightly reduced the risk of hospital admissions and death.
Some five million Americans have heart failure, in which the heart fails to pump enough blood for the body’s needs, and an estimated 500,000 cases are diagnosed each year. Though medication and other treatments exist, patients often suffer from poor quality of life. Simple activities like climbing stairs leave them tired and short of breath; they are frequently hospitalized and at high risk for premature death.
The trial followed 2,331 stable heart failure patients from the United States, Canada and France, with a median age of 59. Fewer than one-third were women. The patients were randomly assigned to their usual medical care or to standard treatment combined with an aerobic exercise program, then followed for two and a half years on average.
Exercise participants began by using a treadmill or a stationary bicycle 15 minutes to 35 minutes three times a week, working up to 40 minutes five times a week.
Death and hospitalization rates were only slightly lower in the exercise group. About 65 percent, or 759 patients, in the exercise training group died or were hospitalized, compared with 68 percent, or 796 patients, in the usual care group. After accounting for several variables, the scientists determined that patients who exercised cut their risk of death and hospitalization by 11 percent.
Dr. Kathryn E. Flynn, an assistant professor of psychiatry and behavioral sciences at the Duke School of Medicine, said over half of the patients who exercised had palpable improvements in quality of life measures, compared with only 29 percent in the group that received usual care.
According to a clinical trial on patients with heart failure, light exercise is______.
选项
A、conducive to the improvement of life quality
B、not likely to replace the standard treatment
C、only complementary to usual medical care
D、effective to reduce the risk of dying soon
答案
A
