          Abstract

          Sixty dogs with idiopathic dilated cardiomyopathy were randomly treated with traditional therapy - digitalis, diuretics, angiotensin-converting inhibitors - (group A) or treated with these drugs plus carvedilol (group B). Echocardiographic variables were measured before and after 3, 13, 26, and 52 weeks of treatment or until death. Comparisons between groups and time were performed. No significant differences between groups were found in the most of the echocardiographic variables. The left ventricular end-systolic diameter indexed to body surface area (LVESDi) increased significantly in the group A dogs compared to the group B animals. The survival of groups A and B dogs were not different (P-value=0.1137). In conclusion, the stability of the LVESDi observed in the group treated with carvedilol may represent the beneficial effect over the ventricular remodeling.

          Sessenta cães com cardiomiopatia dilatada idiopática receberam, aleatoriamente, tratamento convencional - digitálicos, diuréticos, inibidores da enzima conversora de angiotensina - (grupo A) ou esses fármacos mais carvedilol (grupo B). As variáveis ecocardiográficas foram avaliadas antes e depois de três, 13, 26 e 52 semanas de tratamento ou até o óbito. Não foram encontradas diferenças significativas entre os grupos de animais quanto à maioria das variáveis ecocardiográficas. O diâmetro sistólico final do ventrículo esquerdo indexado à superfície corpórea (DSVEi) aumentou de forma significativa no grupo A quando comparado ao grupo B. Não se observou diferença na sobrevida dos grupos A e B (P=0,1137). Concluiu-se que a estabilização do DSVEi no grupo tratado com carvedilol pode representar o efeito benéfico deste fármaco sobre o remodelamento ventricular.

            Marked improvement in left ventricular ejection fraction during long-term beta-blockade in patients with chronic heart failure: clinical correlates and prognostic significance.

            Some patients with heart failure (HF) may have a marked improvement in left ventricular ejection fraction (LVEF) after long-term beta-blockade. We compared the clinical characteristics and the prognosis of these patients with those of other patients. One hundred seventy-one patients with chronic HF were assessed before and after 9 to 12 months of maintenance therapy with metoprolol or carvedilol. Thirty-eight patients (22%) showed an increase in their LVEF >or=15 units (from 20% +/- 8% to 43% +/- 10%). Compared with the other patients (LVEF change from 21% +/- 7% to 26% +/- 9%, P or=0.15 in LVEF. Patients who show a marked improvement in their LVEF after long-term beta-blockade have an excellent prognosis and have a high prevalence of nonischemic HF and a higher blood pressure at baseline.

              Left ventricular filling in dilated cardiomyopathy: relation to functional class and hemodynamics.

              Left ventricular systolic function does not correlate well with functional class in patients with dilated cardiomyopathy. To determine whether the correlation is better with Doppler indexes of left ventricular diastolic function, 34 patients with dilated cardiomyopathy (M-mode echocardiographic end-diastolic dimension greater than 60 mm, fractional shortening less than 25%, increased E point-septal separation) were studied. Patients were classified into two groups according to functional class. Group 1 consisted of 16 patients in New York Heart Association functional class I or II; group 2 included 18 patients in functional class III or IV. Left ventricular dimensions, fractional shortening, left ventricular mass, meridional end-systolic wall stress, peak early and late transmitral filling velocities and their ratio, isovolumetric relaxation period and time to peak filling rate were computed from pulsed wave Doppler and M-mode echocardiograms and calibrated carotid pulse tracings. Right heart catheterization was performed in 20 of 34 patients. No differences were observed between groups with regard to age, gender distribution, heart rate, blood pressure and M-mode echocardiographic-derived indexes of systolic function. Peak early filling velocity (72 +/- 13 versus 40 +/- 10 cm/s, p less than 0.001) was higher and atrial filling fraction (27 +/- 4% versus 46 +/- 8%, p less than 0.001) was lower in group 2 than in group 1. The ratio of early to late transmitral filling velocities was higher in group 2 patients (2.3 +/- 0.5 versus 0.7 +/- 0.2, p less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)
