title: [Prognostic factors in dilated cardiomyopathy].
abstract: Thirty-eight patients, 27 men and 11 women, mean age 49 +/- 12 yr, suffering from dilated cardiomyopathy were included in this prospective study of prognostic factors. Twenty-two subjects admitted heavy alcohol consumption (greater than 80 g/d, for at least 10 yr). The survival rates for 2, 5 and 7 yr were 87, 35 and less than 20%, respectively. Prognostic factors were evaluated in 34 (22 alcoholic and 12 non-alcoholic) patients: 10 improved or were cured, as determined clinically, radiologically and echocardiographically (group 1); 24 deteriorated, 13 of whom died (group 2). Statistically significant values for group 1 versus group 2 were: echocardiographic left ventricular (LV) end diastolic diameter (3.50 +/- 0.80 vs 4.02 +/- 0.5 cm/m2, p less than 0.026) and LV end systolic diameter (2.97 +/- 0.65 vs 3.43 +/- 0.53 cm/m2, p less than 0.02); hemodynamic LV systolic pressure (113.9 +/- 15 vs 101.82 +/- 17.36 mm Hg, p = 0.045); angiographic LV end diastolic volume (137.8 +/- 57.44 vs 177.85 +/- 55.45 ml/m2, p = 0.057), LV end systolic volume 93 +/- 53.5 s 139.28 +/- 48.99 ml/m2, p less than or equal to 0.036), ejection fraction 0.36 +/- 0.16 vs 0.22 +/- 0.7%, p less than or equal to 0.006) and velocity of fiber shortening (0.79 +/- 0.53 vs 0.36 +/- 0.3 circ/s, p = 0.036). Other electrical, radiological and hemodynamic parameters were not significant and alcohol consumption did not influence the prognosis. The severity of LV functional impairment appears to be the major determinant of a poor prognosis and reduced survival in idiopathic and alcoholic cardiomyopathies.
