          Abstract

          ResumenJustificación:el trabajo pretende obtener respuestas, sobre la relación existente entre la funcionalidad y el grado de hipertrofia ventricular izquierda, en los pacientes adultos mayores quienes padecen la hipertensión arterial sistémica, objetivizando ese grado de hipertrofia ventricular izquierda, mediante el estudio ecocardiográfico.Materiales y métodos:este trabajo se realizó mediante un estudio descriptivo, observacional, y retrospectivo de los registros médicos, se consideró a los pacientes hipertensos, a quienes se les realizó un estudio ecocardiográfico, entre los meses de julio y diciembre del 2011 en el Servicio de Cardiología, y a su vez, fueron valorados en la consulta de la Unidad de Valoración Geriátrica del Hospital Nacional de Geriatría y Gerontología.Resultados:Los datos obtenidos en la investigación, revelan una población, predominantemente, conformada por mujeres de la octava década de la vida, quienes tienen más de diez años de ser hipertensas, con hipertrofia ventricular izquierda leve, y cuyas comorbilidades asociadas son diabetes tipo 2, insuficiencia cardiaca y trastorno de la marcha.Se hace también, la descripción del estado funcional, tanto en las actividades básicas de la vida diaria con la escala de Barthel, como en las actividades instrumentales de la vida diaria con la escala de Lawton, relacionándolas con el grado de hipertrofia ventricular izquierda y otras comorbilidades asociadas.Conclusión: se obtuvo, que la población estudiada mantenía buenos niveles de independencia en las actividades básicas de la vida diaria, sin embargo, los pacientes que mantenían hipertrofia ventricular izquierda moderada asociaban dependencia parcial en las actividades instrumentales de la vida diaria según test de Lawton.

          AbstractJustification:this study pretends to obtain an answer about the relationship between functionality and left ventricular hipertrophy, in the elderly patients with high blood pressure, the degree of left ventricular hipertrophy was obtain by echocardiogram study.Materials and methods:descriptive and observational study. Data from patients with high blood pressure, who had an echocardiogram study from July thru December 2011 in the cardiology services, and then had an integral geriatric evaluation in the National Hospital of Geriatrics and Gerontology.Results:data obtained in this study shows a poblation main conformed by women on the eight decade, who had more than ten year of the diagnosis of high blood pressure, with mild left ventricular hipertrophy, in other disseases asotiated were type 2 diabetes, congestive heart failure, and wait problems.The functional state was described, on the basic daily activities with Barthel scale, also on the instrumental activities with Lawton scale, and the relation with left ventricular hypertrophy as other morbilities.Conclusion: the patients of this study maintained good levels of independence on basic daily activities, but the patients who had moderate left ventricular hypertrophy were associated with partial dependence of the instrumental activities of daily living as the Lawton scale showed.

          Echocardiography-based left ventricular mass estimation. How should we define hypertrophy?

          Left ventricular hypertrophy is an important risk factor in cardiovascular disease and echocardiography has been widely used for diagnosis. Although an adequate methodologic standardization exists currently, differences in measurement and interpreting data is present in most of the older clinical studies. Variability in border limits criteria, left ventricular mass formulas, body size indexing and other adjustments affects the comparability among these studies and may influence both the clinical and epidemiologic use of echocardiography in the investigation of the left ventricular structure. We are going to review the most common measures that have been employed in left ventricular hypertrophy evaluation in the light of some recent population based echocardiographic studies, intending to show that echocardiography will remain a relatively inexpensive and accurate tool diagnostic tool.

            Left atrial volume and geometry in healthy aging: the Cardiovascular Health Study.

            The left atrium is a validated marker of clinical and subclinical cardiovascular disease. Left atrial enlargement is often seen among older individuals; however, there are few population-based data regarding normal left atrial size among older persons, especially from those who are healthy, and from women. Furthermore, because the left atrium is a 3D structure, the commonly used parasternal long-axis diastolic diameter often underdiagnoses left atrial enlargement. We evaluated left atrial size in 230 healthy participants (mean age, 76+/-5 years) free of prevalent cardiac disease, rhythm abnormality, hypertension, and diabetes selected from the Cardiovascular Health Study, a prospective community-based study of risk factors for cardiovascular disease in 5888 elderly participants. In addition to the standard long-axis measurement, we obtained left atrial superoinferior and lateral diameters and used these dimensions to estimate left atrial volume. These measurements were used to generate reference ranges for determining left atrial enlargement in older men and women, based on the 95% percentiles of the left atrial dimensions in healthy participants, both unadjusted, and after adjustment for age, height, and weight. In healthy elderly subjects, indices of left atrial size do not correlate with age or height but with weight and other measures of body build. These data provide normative reference values for left atrial size in healthy older women and men. The results should be useful for refining diagnostic criteria for left atrial dilation in the older population and may be relevant for cardiovascular risk stratification.
