Observational studies and clinical experiments solidly establish an empiric relationship between heavy drinking (>/= 3 standard drinks/day) and higher blood pressure. A biologic mechanism for this link remains unclear. It has been difficult to study the incidence of usual hypertension sequelae in alcohol-associated hypertension because of complex interactions of alcohol, hypertension and cardiovascular conditions. Even with these limitations, a causal association is the most likely explanation and control of alcohol intake is probably important in prevention and treatment of hypertension.
