| الوصف: | OBJETIVO: Este estudo compara a sobrecarga contínua versus intermitente do ventrículo direito (VD) de cabritos, para induzir a hipertrofia ventricular. MÉTODO: Foram utilizados três grupos de sete cabritos jovens (controle, contínuo, intermitente). A sobrecarga sistólica foi imposta por 96 horas, no contínuo e por quatro períodos de 12 horas, alternados com 12 horas de descanso, no intermitente. Avaliações ecocardiográficas e hemodinâmicas foram feitas diariamente. Os animais foram, então, mortos para avaliar o conteúdo de água e peso das massas cardíacas. RESULTADOS: O Intermitente mostrou aumento dos pesos de VD e de septo, em relação ao controle (pOBJECTIVE: This study compares ventricular hypertrophy induced by continuous versus intermittent systolic overload of the pulmonary ventricle (RV) of young goats. METHODS: Three groups of seven goats were used (control, continuous, and intermittent). Systolic overload was maintained for 96 hours in the continuous group, while the intermittent group suffered four 12-hour periods of systolic overload, alternating with 12-hour resting periods. Echocardiographic and hemodynamic evaluations were performed every day. The animals were then killed for myocardial water content and weight evaluation. RESULTS: Both study groups achieved significant increases in RV mass (p |
