Background: Although regular physical activity benefits cardiovascular health, there is a concern that intense exercise is linked to the promotion of atrial fibrillation (AF) and coronary plaque rupture. However, the impact of physical activity on the outcomes of patients with concomitant AF and coronary artery disease (CAD) remains unclear. This study aimed to evaluate the association with clinical outcomes according to the level of physical activity in patients with concomitant AF and CAD.
Methods: We assessed 551 patients with AF and CAD (mean age, 67.1?±?9.8 years) who completed a self-reported questionnaire for physical activity from 2015 to 2020 in a single tertiary-care hospital. Physical activity levels were converted into metabolic equivalent of task (MET) per week and categorized to correspond with multiple public health recommendations. We examined the association between physical activity, all-cause mortality, and major adverse cardiac and cerebrovascular events (MACCE).
Results: The risks of all-cause mortality (P for linear trend?=?0.017) and MACCE (P for linear trend?=?0.05) appeared inverse trend with a greater level of physical activity. Compared with inactive patients, patients who met the recommended target range of physical activity (500?1,000 MET-min/week: unadjusted hazard ratio [HR]?=?0.58, 95% confidence interval [CI]?=?0.36?0.99) and highly active patients who exceeded the minimum recommended level (≥?1,000 MET-min/week: unadjusted HR?=?0.47, 95% CI?=?0.25?0.88) had a lower risk of all-cause mortality in the unadjusted model; however, these associations did not remain significant after adjusting for the model. There was no evidence of increased risk of all-cause mortality and MACCE at levels of physical activity above the recommended target range, even with vigorous-intensity physical activity exceeding the recommended target range.
Conclusions: There appears to be an inverse trend between physical activity levels and all-cause mortality and MACCE in patients with concomitant AF and CAD. No excess risk of mortality or MACCE was found at exercise levels above the recommended target range. Further large-scale studies are warranted to create an improved evidence base concerning the effects of physical activity in patients with AF and CAD.
