Alcohol and Hypertension —New Insights and Lingering Controversies

AbstractPurpose of ReviewTo examine outstanding issues in the relationship of alcohol to hypertension. These include whether the increase in BP with alcohol is causally related, the nature of the relationship in women, the contribution of alcohol-related increases in BP to cardiovascular disease and the aetiology of alcohol-related hypertension.Recent FindingsIntervention studies and Mendelian randomisation analyses confirm the alcohol –BP relationship is causal. The concept that low-level alcohol intake reduces BP in women is increasingly unsustainable. Alcohol-related hypertension is in the causal pathway between alcohol use and increased risk for several cardiovascular outcomes. The aetiology of alcohol-related hypertension i s multifactorial with recent data highlighting the effects of alcohol on the vasoconstrictor 20-HETE and oxidative stress.SummaryThe high prevalence of both alcohol use and hypertension mandates a careful alcohol history in every patient with elevated BP. Early intervention for excessive alcohol use offers the promise of lower levels of BP and reduced risk of adverse cardiovascular outcomes.
