title: Alcohol and the cardiovascular system: research challenges and opportunities.
abstract: Excessive alcohol consumption has long been associated with cardiovascular disorders, including cardiomyopathy, hypertension, coronary artery disease, and stroke. However, recent evidence suggests that moderate alcohol intake can actually provide a measure of cardioprotection, particularly against coronary heart disease and ischemia-reperfusion injury. To explore the various dimensions of these opposing actions of alcohol, the National Institute on Alcohol Abuse and Alcoholism and the National Heart, Lung, and Blood Institute sponsored a state-of-the-art workshop on "Alcohol and the Cardiovascular System: Research Challenges and Opportunities" in Bethesda, Maryland, in May 2003. Speakers discussed the following topics: the epidemiology of alcohol and cardiovascular disease, clinical manifestations of alcohol, genetics of alcohol and cardiovascular disease, mechanisms underlying the molecular and cellular effects of alcohol, the application of new and emerging technology, and translation from discovery to therapeutic modalities of treatment. The panel concluded that future studies are needed to: 1) determine the role of genes and the environment in assessing mechanisms underlying the benefits of alcohol use and cardiovascular disease risk; 2) define the biological mechanisms underlying alcohol-induced peripheral vascular damage; 3) clarify the role of genetic variation in alcohol-metabolizing enzymes, genetic susceptibility, and pharmacogenomics in determining cardiovascular disease risk and effective treatment; 4) determine common mechanisms underlying alcohol-induced cardiovascular disease, such as oxidative stress and inflammation; 5) assess the role of insulin resistance, blood clotting, protein kinase C isoforms, and signal transduction mechanisms mediating alcohol's beneficial effects; and 6) explore the potential of stem cells in myocardial regeneration and repair in hearts damaged by alcohol.
