Key result
Moderate alcohol intake linked to less microvascular dysfunction versus light intake, showing a J-shaped relationship.
Why the study?
Alcohol consumption may be a determinant of microvascular dysfunction, which contributes to major clinical diseases such as stroke, dementia, and chronic kidney disease.
Does moderate alcohol consumption reduce microvascular dysfunction compared to light consumption in a general adult population?
Cross-Sectional (n=3,120)
Does moderate alcohol consumption reduce microvascular dysfunction compared to light consumption in a general adult population?
Effect estimate: Standardized beta -0.10 (95% CI -0.19 to -0.01)
Moderate alcohol consumption is associated with less microvascular dysfunction compared to light consumption, with a J-shaped relationship modified by sex and cardiovascular history.

Heide et al. (2022) reported a cross-sectional. Moderate alcohol consumption vs. Light alcohol consumption was evaluated on Total microvascular dysfunction (MVD) composite score (Standardized beta -0.10, 95% CI -0.19 to -0.01). Moderate versus light alcohol consumption was associated with less microvascular dysfunction (standardized beta -0.10; 95% CI -0.19 to -0.01), demonstrating a J-shaped relationship.
