The aim of this study was to review biochemical and electrocardiographic parameters on a group of patients diagnosed with alcoholic cardiomyopathy in order to see which correlates with a poor outcome. The analysis showed different degrees of hyponatremia, without a statistically significant correlation to outcome. We did not find a positive connection between the impaired renal function and severe evolution. On the other hand, LBBB presence was strongly correlated with the poor outcome (p<0.00001). We emphasize the importance of alcoholic dilated cardiomyopathy proportions in the study group and the prognostic value of LBBB presence for negative outcome.
