Performing 150 to 300 minutes of moderate physical activity, or 75 to 150 minutes of vigorous activity, weekly is associated with a lower risk of heart failure (HF), regardless of clinical, sociodemographic and lifestyle factors, suggests a UK Biobank study.
Adults who logged 150 to 300 minutes of objectively measured moderate physical activity (PA) in a week, measured with wrist accelerometers, had a 63% lower risk of heart failure, and those who logged 75 to 150 minutes of activity intense physical activity had a 66% lower risk.
the results, Posted online August 29 at circulationare consistent with previous studies and reflect the latest U.S other World Health Organization Physical activity recommendations for adults of all ages.
More is better, up to a point
“Our study is the largest to date using wrist accelerometers to measure BP,” said Carlos Celis-Morales, PhD, BHF Glasgow Cardiovascular Research Centre, University of Glasgow, Scotland, UK. elcorazon.org | Medscape Cardiology. “Current evidence is based primarily on self-report questionnaires, which are prone to recall bias and thus could obscure the true link between BP and heart failure risk.”
The team analyzed data from 94,739 UK Biobank participants (mean age about 55; about 40% of men) who had not been diagnosed with heart failure or had previous heart failure. myocardial infarction.
BP was measured 24 hours a day, 7 days a week for 1 week with an Axivity AX3 wrist-worn triaxial accelerometer. Minutes per week of light, moderate, and vigorous intensity PA were defined as time spent running 30 to 125 mGRAM>125 to 400mGRAMand >400mGRAM intensity activity, respectively.
During a median of 6.1 years of follow-up after the 1-week FA measurement, the overall incidence of HF was 98.5 per 10,000 person-years.
After adjusting for age, sex, ethnicity, education, smoking, deprivation index, body mass index (BMI), waist-hip circumference, and intake of fruits/vegetables, red meat, processed meat, oily fish, and alcohol, those who participated in 150 to 300 min/week of moderate-intensity PA (hazard ratio, 0.37) and 75 to 150 min/week of vigorous-intensity PA (HR, 0.34) had a lower HF risk compared with those who did not perform PA of moderate to moderate intensity. vigorous PA.
Participants who did more PA were generally younger; they are more likely to be female, white, and college graduates; less likely to smoke; and ate more fruits and vegetables and less red and processed meat. They also had lower BMIs and were less likely to have high blood pressure, type 2 diabetesor take statistics.
The lowest HF risk was achieved at 600 min/week of moderate physical activity and leveled off thereafter.
Furthermore, the association between vigorous-intensity PA and HF was inverse J-shaped, with potentially less risk reduction beyond 150 min/week.
The authors conclude: “Current recommendations for vigorous-intensity physical activity should be encouraged, but not increased. Conversely, increasing moderate-intensity physical activity may be beneficial even among those who meet current recommendations.”
Celis-Morales added: “Although the recommendations are very clear, low levels of physical activity in the population are more related to how well people can fit physical activity into their busy routines than to understanding the amount of physical activity needed. Application of behavior change techniques to promote and maintain physical activity levels on a routine basis would be very important.”
Doctors on board?
“We need to improve physician training and knowledge about prescribing PA,” Celis-Morales noted. “As far as we know, exercise prescription it has not been a key component in his medical training. Incentives could be a way to address reluctance among clinicians, even if they (have to) be context-dependent.”
Charles German, MD, an assistant professor of medicine in the section of cardiology at the University of Chicago, Illinois, who was not involved in the study, also stressed the need for physician awareness and action in a comment to elcorazon.org | Medscape Cardiology.
“Physicians would greatly benefit from more education about the benefits of PA, which would translate into better counseling and patient care,” said German, who sits on the Council’s Cardiometabolic Health and Lifestyle Committee of the American Heart Association. “It is absolutely necessary that they take it upon themselves to educate and promote PA to their patients by any means necessary.”
“Although moderate-to-vigorous physical activity is known to be associated with reductions in cardiovascular disease, so is low-intensity physical activity,” he added. “Clinicians should not discount the fact that even light-intensity PA can translate into reductions in the risk of heart failure and other diseases.”
The study was partly funded by the University of Glasgow Revitalizing Research Fund. No relevant disclosures were reported.
