title: Relation of left ventricular function to habitual alcohol consumption.
abstract: Left ventricular (LV) dysfunction is a frequent finding in chronic alcoholic subjects. LV function's relation to alcohol use in the general population, where low and moderate consumption predominate, was studied in this work. A random sample of 120 people born in 1954 was invited to participate in the study, and 93 (42 men and 51 women) enrolled. Ethanol use was studied by 2-month daily recording of all alcoholic drinks; smoking and physical activity were quantified likewise, and salt intake by 7-day food records. Subsequently, subjects underwent an LV examination by M-mode echocardiography, and a transmitral flow velocity study by pulsed Doppler ultrasound. The relations of LV measurements to alcohol use were studied by multiple linear regression adjusting for sex, body size, blood pressure, heart rate, smoking, physical activity and dietary salt intake. No subject had clinical heart disease. The average daily ethanol consumption ranged from 0 to 1.2 g/kg of body weight (median 0.2). Statistically significant associations with square-root daily ethanol use were found for LV end-systolic diameter (regression coefficient [b] +/- SE 4.0 +/- 1.5 mm/square root of g/kg; p < 0.01), fractional shortening (b = -3.9 +/- 1.8%/square root of g/kg; p < 0.05), peak early transmitral velocity (b = -8.9 +/- 3.5 cm/s/square root of g/kg; p < 0.05), and peak atrial transmitral velocity (b = -4.9 +/- 1.9 cm/s/square root of g/kg; p < 0.05). No interactions with sex were observed.(ABSTRACT TRUNCATED AT 250 WORDS)
