RESUMO
Se realizó un estudio descriptivo transversal de 120 pacientes hipertensos con 5 o más años de evolución, quienes acudieron al cuerpo de guardia del Hospital Provincial Docente "Saturnino Lora" de Santiago de Cuba, desde noviembre de 2010 hasta igual mes de 2011, con vistas a determinar la presencia o ausencia de alteraciones ecocardiográficas típicas de hipertensión arterial. De ese total, 78,3 % resultaron afectados, la mayoría de los cuales refirieron no seguir tratamiento médico previo regular y 21,7 % no presentaron estas modificaciones. En la casuística predominaron el grupo etario de 50-60 años, el sexo masculino y el color negro de la piel. Los hallazgos ecocardiográficos más llamativos fueron: la hipertrofia ventricular izquierda y la insuficiencia cardíaca con fracción de eyección del ventrículo izquierdo conservada.
A descriptive cross-sectional study was carried out in 120 hipertensive patients with a course of 5 or more years, who went to the emergency room of "Saturnino Lora" Provincial Teaching Hospital from November 2010 to November 2011 in order to determine the presence or absence of echocardiographic abnormalities typical of hypertension. Of these, 78,3 % was affected, most of whom reported not to continue with regular previous medical treatment, and 21,7 % had not these abnormalities. Age group of 50-60 years, males and blacks prevailed in the case material. The most significant echocardiographic findings were left ventricular hypertrophy and heart failure with ejection fraction of left ventricle preserved.
RESUMO
PURPOSE: The purpose of this study was to evaluate M-mode echocardiographic abnormalities in infants of relatively well controlled diabetic mothers and to determine the timing of spontaneous regression. METHODS: Echocardiographic study was prospectively carried out in 9 neonates born to diabetic mothers(infants of diabetic mothers, IDM) and 6 newborn infants(control) matched for weight and age. And the study were repeated in 3 of 9 IDM(follow up) after 3 to 16 months. M-mode echocardiography included measurements of left and right ventricular free wall and interventricular septal thickness and ventricular diastolic and systolic dimensions; LV function is expressed as shortening fracion. RESULTS: Interventricular septal thickness(0.56+/-0.13 vs 0.32+/-0.09) and STd/PWTd(2.04+/-0.60 vs 1.19+/-0.44) were significantly higher in infants of diabetic mothers thanin control newborn infants. Follow up measurements showed regression of interventricular septal thickness(2.13+/-0.58 vs 1.02+/-0.66/M2) but no significant improvement in STd/PWTd(2.04+/-0.60 vs 1.67+/-1.25) compared with initial measurements. CONCLUSION: M-mode echocardiographic abnormalities including interventricular septal hypertrophy and high STd/PWTd were observed even in infants of relatively well controlled diabetic mothers and may persist for a somewhat longer period.
