  • Title: Myocardial hypertrophy, cardiac and urinary catecholamines during severe ethanol intoxication and withdrawal.
    Author: Adams MA, Hirst M.
    Journal: Life Sci; 1983 Aug 08; 33(6):547-54. PubMed ID: 6224996.
    Abstract:
    Cardiomegaly was observed in rats severely intoxicated with ethanol for a 4 day period. It was apparent at 48 hours of treatment, a time at which cardiac protein was elevated and continued into withdrawal. During a 4 day abstinence period the degree of hypertrophy declined towards normal. Cardiac noradrenaline was reduced at the 48 hour time of intoxication, then increased gradually in the further experimental period. As the cardiac hypertrophy occurs at a time that urinary catecholamines are elevated and the adrenal medulla is intensely stimulated, it is proposed that increased levels of circulating catecholamines are largely responsible for the enlargement of the heart.
