Preclinical abnormaltiy of left ventricular function in chronic alcoholics.

Left ventricular function of a sample of subjects with chronic alcohol intake, in the form of wine, and without clinical or electrocardiographic signs of heart disease was compared with that of a sample of normal control subjects using non-invasive polygraphic recordings. The statistical analysis has shown significant prolongation of PEP, PEPI, an increase in PEP/LVET, and a shortening of LVET and LVETI in the alcoholic subjects compared with the controls. All these abnormalities may be ascribed to left ventricular malfunction.
