TUESDAY, March 20, 2018 (HealthDay News) — Physical activity (PA), but not weight loss, is associated with improved survival in coronary heart disease (CHD), according to a study published in the March 13 issue of the Journal of the American College of Cardiology<\/i>.<\/p>\n
Trine Moholdt, Ph.D., from the Norwegian University of Science and Technology in Trondheim, and colleagues studied 3,307 individuals with CHD and examined the hazard ratio (HR) for all-cause and cardiovascular disease (CVD) mortality, calculated according to changes in body mass index and PA.<\/p>\n
The researchers identified 1,493 deaths during 30 years of follow-up. There was a correlation for weight loss with increased all-cause mortality (adjusted HR, 1.3; 95 percent confidence interval [CI], 1.12 to 1.5). There was no correlation for weight gain with increased mortality (adjusted HR, 0.97; 95 percent CI, 0.87 to 1.09). Increased risk in association with weight loss was limited to those who were normal weight at baseline (adjusted HR, 1.38; 95 percent CI, 1.11 to 1.72). Compared with participants who were inactive over time, the risk for all-cause mortality was lower for those who maintained low PA (adjusted HR, 0.81; 95 percent CI, 0.67 to 0.97) or high PA (adjusted HR, 0.64; 95 percent CI, 0.5 to 0.83). Similar associations were seen for CVD mortality.<\/p>\n
“Increased attention should be placed on strategies to increase PA in secondary prevention of CHD,” the authors write.<\/p>\n
