Association of physical activity and lower respiratory tract infection outcomes in patients with cardiovascular disease

The dose‐response correlation between physical activity and lower respiratory tract infection (LoRI) outcomes was examined in patients with cardiovascular disease.
Using the Korean National Health Insurance data, researchers retrieved data of individuals aged 18 to 99 years (mean age, 62.6 ± 11.3 years; women, 49.6%) with cardiovascular disease who underwent health screening from January 1, 2009, to December 31, 2012 (n = 1,048,502) and were followed up until 2018 for mortality and until 2019 for hospitalization.
Self‐reported questionnaires were used to assess the amount of physical activity and categorization of physical activity was done into 5 groups: 0 (completely sedentary), < 500, 500 to 999, 1,000 to 1,499, and ≥ 1,500 metabolic equivalents of task min/wk.
Analyses revealed that patients with cardiovascular disease exhibit a reduced risk of mortality and hospitalization from LoRI in correlation with engaging in even a low level of physical activity compared with being completely sedentary, and incremental risk reduction occurs with increased physical activity.
