This study was aimed to investigate the association between joint moderate-to-vigorous physical activity (MVPA) and alcohol intake and all-cause mortality in patients with CVD.MethodsA total of 4,047 participants from the National Health and Nutrition Examination Survey (NHANES) with self-reported CVD history, exercise and alcohol consumption amounts were included this study. Participants were stratified into 12 groups by MVPA level (none/insufficient/sufficient) and alcohol intake (abstainer/light/moderate/heavy). Restricted cubic spline and Cox regression models assessed mortality associations.ResultsMVPA showed an L-shaped association with mortality, while alcohol exhibited a U-shaped pattern. The lowest observed mortality risk occurred in patients with MVPA ≥150 min/week and alcohol consumption 8.4–15.4 drinks/week (HR = 0.348, 95% CI: 0.169–0.667). Comparably lower risk was seen with MVPA <150 min/week plus light alcohol intake (<8.4 drinks/week) (HR = 0.400, 95% CI: 0.267–0.588).ConclusionAmong patients with established CVD, any level of MVPA was associated with survival benefits. The greatest mortality reduction occurred with >150 min/week of MVPA alongside light to moderate alcohol consumption (<15.4 drinks/week). However, comparable survival benefits were observed with <150 min/week of MVPA when coupled with light alcohol intake. MVPA remains the cornerstone for mortality risk reduction in this population.
