Key result
Cardiac overexpression of alcohol dehydrogenase significantly augmented ethanol-induced depression of cell shortening (43.7% vs 23.3%) and intracellular Ca2+ (40.6% vs 23.4%) in mouse myocytes.
Why the study?
Does overexpression of alcohol dehydrogenase exacerbate ethanol-induced contractile defects in cardiac myocytes?
Does overexpression of alcohol dehydrogenase exacerbate ethanol-induced contractile defects in cardiac myocytes?
Absolute Event Rate: 43.7% vs 23.3%
Elevated cardiac acetaldehyde exposure due to enhanced ADH expression exacerbates ethanol-induced contractile defects, suggesting a mechanism for the development of alcoholic cardiomyopathy.

Hypothesis-generating for acetaldehyde in alcoholic cardiomyopathy; human studies needed before clinical relevance.
Duan et al. (2002) studied Alcoholic cardiomyopathy. Cardiac overexpression of alcohol dehydrogenase (ADH) vs. Wild-type (FVB) mice was evaluated on Maximal inhibition of cell shortening upon acute exposure to ethanol. Cardiac overexpression of alcohol dehydrogenase significantly augmented ethanol-induced depression of cell shortening (43.7% vs 23.3%) and intracellular Ca2+ (40.6% vs 23.4%) in mouse myocytes.
