All-cause and cardiovascular disease (CVD) mortality are higher among patients with chronic obstructive pulmonary disease (COPD). We examined the association between American Heart Association’s Life’s Simple 7 (LS7) metrics and all-cause as well as CVD mortality in patients with COPD.
We examined 1513 US adults with COPD aged ≥ 40, without prior CVD, from the National Health and Nutrition Examination Survey III. COPD was defined as FEV/FVC<0.7 in absence of asthma. Adjusted Cox regression was used to assess the relation of LS7 metrics with all-cause and CVD mortality.
Overall, only 74 participants (4.9%) had ideal 5-7 LS7 metrics. Over a mean follow-up of 14.2±7.9 years, 1162 individuals died, of which 315 were due to CVD. Age, sex, and ethnicity-adjusted HRs (95% CI) for all-cause mortality were 0.53 (0.41-0.68), 0.45 (0.34-0.59), 0.66 (0.49-0.87) and 0.75 (0.56-1.00) among those with ideal vs poor control of smoking, diet, physical activity and fasting blood glucose, respectively. However, the ideal and intermediate LS7 metrics were not significantly associated with lower risk of CVD mortality, except for a BMI between 25-29.9 kg/m. Those with 5-7 vs 0-1 ideal metrics had adjusted HRs 0.50 (0.40-0.87) for all-cause and 0.53 (0.21-1.36) for CVD mortality.
Ideal levels of multiple behavioral and health factors are associated with substantially lower risks for all-cause mortality, with a trend for lower CVD mortality among US adults with COPD.
