Alcohol acts as a dose-, pattern-, and host-dependent cardiovascular stressor, producing overlapping but distinct phenotypes across acute, binge, heavy, chronic, and withdrawal exposures.
- Why it matters: Observational cardioprotection at light-to-moderate intake has been challenged, yet uncertainty remains at very low exposure levels and for selected coronary or all-cause outcomes.
- What they did: A systems-cardiology framework integrates mechanisms—ethanol/acetaldehyde toxicity, redox imbalance, microbial and inflammatory mediators, neurohumoral activation, and metabolic/electrolyte disturbances—linking them to endothelial, mitochondrial, electrical, and repair dysfunction.
- The result: Cumulative injury is proposed to drive alcohol-related cardiovascular ageing, unifying mitochondrial dysfunction, inflammageing, senescence, impaired repair, and ventriculo-arterial uncoupling, with direct human evidence still incomplete.
